The question of "What binds the world in its innermost core?" was on Johann Wolfgang von Goethe's mind in "Faust." Many researchers at Chemnitz University of Technology also search for answers to this question. At the new Transmission Electron Microscopy Center (TEM-Center), officially opened on April 14^th, 2026, at Erfenschlager Straße 73 in Chemnitz, researchers aim to visualize structures smaller than the wavelength of visible light. This will enable them to identify atoms, molecules, and the bonds of matter. To achieve this, they will utilize the top-tier research infrastructure.

High-resolution microscopes enable precise material analysis

"The core of the new, single-story building are two highly sensitive transmission electron microscopes that allow us to examine the structure and properties of materials at the molecular and atomic levels, and then translate these findings to new applications," says Prof. Dr. Andreas Undisz, the Chair of Electron Microscopy and Microstructural Analysis at Chemnitz University of Technology and head of the new center. For example, processes that lead to material damage can be examined in very detail, enabling more accurate conclusions to be made about the durability and performance of components.

A worthwhile investment at Chemnitz University of Technology

"With this new building and the two electron microscopes, Chemnitz University of Technology is once again at the forefront of global materials research. The complex technical features offered by this facility as a whole can be found at only a few other locations worldwide. In addition to the three faculties, partner institutions will also benefit. This makes Chemnitz University of Technology even more attractive to top researchers from around the world. Thus, we strengthen the entire scientific region of Southwest Saxony,” said Saxony’s Minister of Science, Sebastian Gemkow, in a statement from the State Ministry of Finance.

"We at Chemnitz University of Technology are delighted to celebrate the opening of the Transmission Electron Microscopy Center. This is an important investment in Chemnitz University of Technology and, by extension, in Chemnitz as a research hub, in our core competencies in materials science and intelligent systems, and in our university’s national and international reputation. We are very grateful to the Free State of Saxony and to everyone involved who actively supported the establishment of the center," says Prof. Dr. Gerd Strohmeier, President at Chemnitz University of Technology. Prof. Dr. Anja Strobel, Deputy President and Vice President for Research and University Development at Chemnitz University of Technology, who represented the Rector in receiving the key, added: "The new Transmission Electron Microscopy Center, which brings together expertise from various research areas at Chemnitz University of Technology, significantly strengthens our university’s STEM field in research and teaching and creates highly attractive conditions for new interdisciplinary research projects as well as for recruiting and training our next generation of academics by providing researchers and students with access to the latest technologies and methods in materials science."

Technological marvels explore the nano cosmos

The electron microscopes, which tower over four meters, capture images of the tiniest structures at the nanometer level. "To ensure these sensitive marvels of technology can operate optimally, they are housed in specially shielded, climate-controlled rooms and rest on a 1.4-meter-thick vibration-damping concrete slab," explains Undisz. This keeps mechanical, acoustic, electromagnetic, and thermal sources of interference at a distance. Experiments using the large-scale research equipment in the protected inner core of the building are conducted remotely from operating rooms. In-depth material analysis using the two transmission electron microscopes requires preparing material samples just a few nanometers thin. This process is semi-automated in an adjacent room using a focused ion beam system.

Researchers from over 20 professorships will work with the equipment in the future

The new center has the advantage of merging all of Chemnitz University of Technology’s high-resolution transmission electron microscopy equipment in one location. More than 20 professorships of the faculties of mechanical engineering, natural sciences, and electrical engineering and information technology will use the equipment for their transdisciplinary and interdisciplinary basic and applied research. They will also collaborate with non-university research institutions, such as Fraunhofer Society institutes, as well as companies.

Background: Transmission Electron Microscopy Center at Chemnitz University of Technology

Construction of the new research building began in September 2023 under the direction of the State Office for Real Estate and Construction Management. The building was designed by Heinle Wischer Partnership of Independent Architects mbB in Dresden. The sculpture "Impact", created by Stefanie Welk from Walldorf near Heidelberg as part of the "Art in Architecture" competition, frames the building’s entrance.

Approximately 13.1 million euros were invested in the construction of the building. Of this amount, approximately 7.4 million euros were provided by the European Regional Development Fund and around 5.7 million euros by the Free State of Saxony. The project was co-financed with tax revenues based on the budget approved by the Saxon State Parliament. The German Research Foundation (DFG) and the Free State of Saxony each provided 3.5 million euros for the large-scale equipment. Professors Christoph Tegenkamp, Martin Wagner, and Bernhard Wunderle successfully acquired the funding on behalf of the three participating faculties at Chemnitz University of Technology.

Sustainability is a central research topic in supply chain management. It encompasses sustainable, environmentally friendly, closed-loop, and circular concepts. A current research paper in this field, "On cost and revenue in circular supply chains: Where to close the loop?", in which the Chair of Factory Planning and Intralogistics (Head: Prof. Dr. Matthias Thürer) at Chemnitz University of Technology is significantly involved, was honored with a "Best Research Award 2024" by the renowned international journal "Cleaner Logistics and Supply Chain." The study, conducted jointly with the Josef Ressel Center for Data-Driven Business Model Innovation in Steyr, Austria, examined companies' cost and revenue sharing through analytical modeling of cash flows in linear and circular multi-stage supply chains.

"Previous research has predominantly focused on dyadic or triadic supply chain structures. The question of where loops should be closed — that is, where recycler, repurposer, remanufacturer, refurbisher, repairer, and/or reuser should be positioned — remains largely unanswered," Thürer summarizes. "We were particularly interested in how the position in the supply chain affects companies' costs and revenues. The results have important theoretical and practical implications. They show that companies upstream of the loop closer are negatively impacted by the reuse of materials. There is therefore a risk that companies will leave circular supply chains if no balancing mechanism is installed," adds the Chemnitz professor.

For the Chair of Factory Planning and Intralogistics, the award from the journal "Cleaner Logistics and Supply Chain" is already the second recognition this year. In March 2025, the International Journal of Production Research named a paper on simulation in relation to resilience as "Top Trending Article 2024".

Keyword: Journal "Cleaner Logistics and Supply Chain"

The Journal "Cleaner Logistics and Supply Chain" is an international, transdisciplinary companion journal to the Journal of Cleaner Production. It focuses on topics related to logistics and supply chains that support the sustainable development of society.

In the year 2030, the University Library has turned into a „5D-Library”. This is the objective determined in the strategy of the University Library of Chemnitz University of Technology which she has published now in short version on a website (mytuc.org/xrfv). In this context, “5D” stands for: digital, dynamic, durable, divers and discursive. Within those thematic fields, the University Library has defined 24 measures in total which will be implemented by already established task teams step by step within the next five years.

“Naturally, we do not start at zero but we may rely on a lot of what we already achieved, for example regarding the engagement for Open Science, the promotion of Open Access, the digitization of our collections, the modularization of services and within sustainability” comments Angela Malz, Director of the University Library. And as so-called “Third Place”, the University Library offers, in addition to the place of work and the own home, a variable location of learning and knowledge inviting to relax, to learn, to stay and to participate in a variety of events and which, within the upcoming years, enhances its portfolio by i.a. a Virtual Reading Hall. Complementarily Malz adds: “Within the strategy, however, we start also a lot of other projects, for example in the field of enhanced engagement in internationalization, in dealing with new AR- and AI-technologies in the library sector as well as in our engagement for long-time-archiving.”

All started with the moving of the University Library to the Old Spinning Mill building in the year 2020. With respect to the concentration from three de-centralized to one central library location, the geographic location and the related task, the new functionalities of the building like an exhibition and an event area as well as to the merging to one team, it was decided to jointly also determine a direction for the short-, mid- and long-term development of the Library. In this context, i.a. workshops with all staff members of the University Library were organized who merged to working groups dealing with respective thematic key fields. At the beginning of 2023, a comprehensive survey among its users consisting of students and scholars of Chemnitz University of Technology, non-scientific staff members as well as external users was implemented. Non-users were included as well. The objective consisted on including the internal as well as the external point of view in the strategy development process. “In total, 630 online-surveys were filled in completely and integrated in the evaluation of results for deriving action measures”, Dr. Wolfgang Lambrecht, Deputy Director of the University Library, reported.

From this emerged a strategy document comprising of more than 40 pages which was presented in summary to the Library Board of Chemnitz University of Technology in December 2024 and was highly appreciated. The short version of the strategic approaches may now be read on the Library-website mentioned above. “I am very delighted that we completed the strategy development process as scheduled so that we may now, right in time of the year of the Capital of Culture, proceed on our way to a 5D-Library” Malz says. In the mid of the strategy period, a mid-term assessment of the way to the “5D-Library” is envisaged where again adherents of Chemnitz University of Technology and external Library users will be asked for their engagement.

The center for micro- and nanotechnologies (ZfM) at Chemnitz University of Technology coordinates the recently started European project HaloFreeEtch to explore novel and sustainable processes for semiconductor manufacturing. The project aims to develop sustainable and halogen-free etching processes for the semiconductor industry by reducing the use of halogene-containing chemicals and energy consumption.

Established semiconductor etching processes rely on halogene-containing materials which pose significant environmental and health risks. Thus, scientists from the ZfM will explore novel approaches to etch silicon or glass by using hydrogen and innovative catalysts. Using such environmentally friendly alternatives will reduce the ecological footprint of the sector significantly.

At the ZfM, quantum chemical simulation methods will be used to screen promising materials on the computer in front of lab scale research to explore the process performance in the clean room environment on state-of-the-art equipment. Together with the partners, novel methodologies for sustainability-driven process development will be established. By combining process- and sustainability models, the use of critical materials as well as the consumption of energy will be tracked and optimized.

“For us it is very important, that the new semiconductor processes are not only environmentally friendly, but also meet the performance requirements of the modern semiconductor industry, leading the industry into a more sustainable future.” says Dr. Jörg Schuster from Chemnitz University of Technology, who is coordinating the European project.

Funded with about four million Euro from the EU, HaloFreeEtch will run for four years. The project consortium involves several leading European research and industry partners, among them the Fraunhofer Institute for Electronic Nano Systems (ENAS) in Chemnitz. The results are expected not only to revolutionize semiconductor manufacturing but also enable applications in areas such as microsensors and photonics.

In this context, the University Library (UL) of Chemnitz University of Technology invites for several events from October 21 to 27. Among them a workshop, a virtual fun riddle and a hands-on activity are being offered at the dining hall Reichenhainer Straße.

The theme of the OAW of 2023 “Community over Commercialization” is determined as focus point again this year due to its urgency. The reason why: Authors, funding organizations, research institutions and service providers like libraries world-wide are reconsidering their ways of transformation to Open Access selected. Which Open Access-business models are really serving at science? Thus, the Open Science Team of the UL would like to discuss its thesis that “All research results should be open to public. Change my mind!” at its booth at dining hall Reichenhainer Straße on October 23 between noon and 2 pm.  

On October 24, the University Library invites to panel discussion at Weinhold-building from 12:30 pm on. The focus is put on the question “Is this the future or just rip-off? Open Access Publishing at Elsevier, Wiley and Springer vs. MDPI and Frontiers”. An input is given i.a. by Prof. Dr. Arved C. Hübler, Head of the Institute for Print and Media Technology. He says: “The publication market counts among the last pillars for good science, it serves for selection – in Open Access as well.” The panel is also joined by Prof. Dr. Robert Kretschmar, holder of the professorship of Inorganic Chemistry. He thinks; “The great challenge of the present peer- review-system is that profits of the publishers are financed by tax money and this in three ways: Scientists elaborate and format the articles, other scientists are reviewing them and last but not least one pays in the one or the other manner. Although, there are alternatives like Diamond Open Access.” To the panel participants counts also Prof. Dr. Olfa Kanoun, holder of the Professorship of Measuring and Sensor Technologies. She may report, jointly with her PhD-students, from nice and less nice experiences with entire Open Access Publishers as well as the traditional publishing system. Persons interested are asked for prior registration for the panel discussion.

The highlight of this year is the according of the “Open Access Award” in different categories. In acknowledgement of their efforts for enhancing Open Access at Chemnitz University of Technology, awards are accorded to some scientists resp. representatives of the different ways of publication: Open Access Gold, Open Access Green, Diamond Open Access and Open Access Monographs.  

Background: Ways of Open Access-publishing

Politics and science are promoting the transformation from Closed Access to the free availability of knowledge. Funding organizations support projects for the establishment of appropriate sustainable infrastructures. Publishers offer different Open Access options. Academic institutions and consortia re-allocate publications costs from subscription to the financing of individual publications. Although authors as well as users do not have to pay for publishing of and access to scientific results, all Open Access ways are not possible without the investment of resources. During the last decades, no way of publication could be determined as royal road on the national as well as on the international level. Also the further enhancement of Diamond Open Access requires intensive reflection on sustainability or potential dependencies.

March 2025 marks the begin of a new „Marie-Skłodowska-Curie doctoral network” titled “CATALOOP - Closing the loop in stereoselective catalysis with data-driven approaches”. This collaborative networks brings together twelve research groups from all over Europe from the fields of catalyst research and data-driven methods in chemistry. As part of the training, the graduate students will work on hard-to-realize catalytic transformations, but will also have the opportunity to apply their skills with one of nine industrial partners. The network is funded by the European Commission with about 2.8 million Euro (of which about 20% is remaining at Chemnitz University of Technology).

To dive a bit deeper into the research: Catalysts are crucial for all kinds of processes in the chemical industry. As a matter of fact, catalytic reactions have been identified as cornerstone technology for green and sustainable chemistry. In the typical approach, new catalysts are being developed in a time and resource-intensive manner, which will optimize after each other key parameters of the reactions such as temperature, concentration, reaction time or pressure. This takes a significant amount of time. This is why methods from data science have appeared also on the scene of synthetic chemistry in the lab. New computer-based methods allow for the parametrization of catalyst molecules and for the use of statistics to optimize the catalysts of interest in a iterative process. This process of optimizing chemical reactions leads to shorter research an development times.

„While the basic methods for data-driven research and development processes are generally known, the exact how-to’s and procedures have not found broad entry into the experimental research groups. One reason for this could be that many of the synthetic chemical research groups have a certain distance to the rather theoretically-driven groups,” says Prof. Dr. Johannes Teichert, professor for organic chemistry at Chemnitz University of Technology and spokesperson of the CATALOOP network. At the same time, the ability to work hand in hand with data science also requires a broader education. “The CATALOOP networks aims to bridge this gap by introducing a joint initial phase in which all researchers develop a common language for their individual research and learn key methods,” adds Teichert. Afterwards, they continue by working in mixed teams of three, keeping synthetic and theoretical chemists in close collaboration. In the end, the data-driven research method will be applied to difficult-to-realize chemical transformations.

Another clearly states goal of the CATALOOP network is to simplify the entry to data-driven chemical research for the general research community: “It is the aim to provide a clear handbook or tool from the experience of this network in which important learnings and working protocols are provided for other researchers,” says Teichert.

Background: Marie-Skłodowska-Curie actions

The European Commission supports scientists in collaborating across borders and building an international career with the so-called Marie-Skłodowska-Curie actions. These actions are part of the European Program “HORIZON 2020”. They are named after Marie Skłodowska-Curie, chemists and physicist of polish origin who lived in France and studied radioactivity. Marie Skłodowska-Curie was awarded two Nobel prizes.

On April 5, 2024, Prof. Ursula Staudinger, Rector of TU Dresden (TUD), Prof. Uwe Götze, Vice-Rector Transfer and Continuing Education at TU Chemnitz (TUC), Prof. Klaus-Dieter Barbknecht, Rector of TU Bergakademie Freiberg (TUBAF), and the Rector of Zittau/Görlitz University of Applied Sciences (HSZG) - Prof. Alexander Kratzsch - signed a cooperation agreement at the industrial park “Schwarze Pumpe” near Spremberg to establish the "Green Circular Economy" (CircEcon) research campus for a greenhouse gas-neutral circular economy, the only one of its kind in Europe. The signing took place in the presence of Thomas Schmidt, Saxon State Minister of Regional Development, and Dr. Andreas Handschuh, State Secretary of the Saxon State Ministry for Science, Culture and Tourism.

With these joint pilot lines, test facilities and demonstration systems, the participants are pooling their expertise in the field of materials and production technologies, as well as process and recycling technology, in order to map future-oriented technologies for the circular economy onto an industrial scale, thus initiating the creation of new jobs through the establishment of companies and spin-offs in the region.

"CircEcon" is scheduled to begin operations at the end of 2026. Up until this date, the Federal Government and the Free State of Saxony will invest around EUR 108M. Around EUR 48M of this will be used for the construction of the center, leaving around EUR 60M for equipment and pilot plants.

Prof. Ursula Staudinger, Rector of TUD: "By signing the contract today, we are creating the basis for a unique cooperation between the three Universities of Technology in Saxony and the Zittau/Görlitz University of Applied Sciences in the highly innovative field of the circular economy, thereby making a valuable contribution to structural change. CircEcon will allow us to establish a unique European technology network for the development of new materials and production technologies as well as process and recycling techniques at the industrial park “Schwarze Pumpe”. TU Dresden is delighted to coordinate the construction measures in close cooperation with its partner universities and on behalf of the Saxon Property and Construction Management. In the future research center, we are exploring the closed circuit from component production to comprehensive recycling and reuse. This will make Lusatia an internationally visible, technological region that excels in the field of the circular economy - a win-win situation that opens up the prospect of new jobs and dynamic development for the region, all the while enabling us to improve research and transfer and to explore new forms of cooperation in the field of the circular economy."

Prof. Uwe Götze, Vice-Rector Transfer and Continuing Education at TUC: "TU Chemnitz is actively pursuing the strategy of setting up regional offices in order to promote its regional effectiveness, as well as effectively establish itself and increase its visibility in the Free State of Saxony, all the while fulfilling its economic and social responsibility. CircEcon is the fourth regional office of our university to be launched - this time as a joint institution in cooperation with three partner universities. This close collaboration will open up new paths towards a highly efficient circular economy through coordinated research activities on the future campus. The transfer of acquired knowledge into innovations will not only provide new approaches to climate protection, but will also make a significant contribution to regional development in Lusatia. We would like to thank the many people involved in this complex and future-oriented project for their valuable input and contributions - especially Prof. Lothar Kroll and his team at Chemnitz University of Technology."

Prof. Klaus-Dieter Barbknecht, Rector of TUBAF: "TU Bergakademie Freiberg is contributing its comprehensive expertise in the fields of processing technology, metallurgy and materials technology to the project. The focus is on the high-quality recycling of composite materials and metallic lightweight materials. With the large-scale pilot plants that will be set up as part of CircEcon, we can accompany innovative technologies from their conception to market maturity. We are certain that this will effect a sustainable transformation of the region and its economy."

Prof. Alexander Kratzsch, Rector of Zittau/Görlitz University of Applied Sciences: "The signing of the cooperation agreement for the 'Green Circular Economy' project marks a very special moment for our Zittau/Görlitz University of Applied Sciences. With this pilot project, which is unique in Europe, we are joining forces and boldly entering the future of the circular economy. CircEcon will not only become an innovation center for sustainable technologies, but also an engine for regional development and new jobs in our home region of Lusatia. It shows what great things universities of applied sciences can achieve and that, alongside strong partners, we can play a pioneering role in shaping a sustainable future."

About CircEcon

Due to the necessary phasing-out of the coal-fired power generation by 2038, Lusatia is in the midst of an accelerated structural change. For the region and its inhabitants, this means major challenges - but also a great opportunity to emerge even stronger. Chemnitz and Dresden Universities of Technologies, TU Bergakademie Freiberg and the Zittau/Görlitz University of Applied Sciences are contributing to this and pooling their expertise in the field of materials and production technologies as well as process and recycling technology. "CircEcon," a center for researching and developing new technologies for recycling and reusing fiber composites from wind turbines, for example, is to be established that is unique in Europe.

With joint pilot lines, test facilities and demonstration systems, research expertise in Saxony is being linked in a targeted manner for the first time, and innovative approaches to the efficient structuring of the circular economy are being developed and marketed alongside regional companies. Modern methods, such as comprehensive digitalization and artificial intelligence, will be used to manage energy and recyclable materials in order to realistically map the entire value chain - from raw material extraction and processing of recyclables and materials to re-production - and to round it all off, it will be done in an industry-relevant, greenhouse gas-neutral manner.

The Professorship of Advanced Powertrains at Chemnitz University of Technology (TUC) is part of a Saxon consortium that aims to put Europe's first hydrogen-powered tramway on the rails in Görlitz at the end of 2026. Funding of around eight million euros has been pledged for this ambitious project, of which 1.2 million euros will go to TUC. The research project "HyTraGen" (Hydrogen-Tramway of the next Generation) has been launched under the leadership of Hörmann Vehicle Engineering GmbH in Chemnitz. The project partners for the prototype are tramway manufacturer Heiterblick GmbH from Leipzig and Flexiva Automation & Robotik GmbH from Amtsberg in the Erzgebirge. The tramway will be tested together with Görlitzer Verkehrsbetriebe (GVB).

"Hydrogen drives will be an integral part of new vehicle developments in the future," says Dr. Volkmar Vogel, Senior Vice President of Hörmann Vehicle Engineering GmbH. With a view to Asia, where H2 tramways are already in use, Hörmann developed the project idea for a catenary-free tramway with hydrogen and fuel cell drive back in 2019. The hydrogen tramway is not intended to be in direct competition with existing overhead lines, but rather an alternative for routes where overhead lines are not necessary or practical. New districts and suburban areas can thus be made accessible much more easily and with lower infrastructure costs.

"In the future, hydrogen will be able to show its advantages above all where large masses are transported over long distances, i.e. especially in heavy duty, freight and passenger transport," says Prof. Dr. Thomas von Unwerth, head of the Professorship of Advanced Powertrains at TUC. For him, the hydrogen tramway is therefore a sensible option, but its practicable use depends on many parameters, especially the availability of hydrogen filling stations. "In addition, H2 tramways must not be much heavier than conventional ones, so the additional weight of the hydrogen tanks must be," says von Unwerth.

"Over the next three years, the research team at the Professorship of Advanced Powertrains will focus in particular on developing a refueling strategy, developing simulation models for the aging of the powertrain and measuring the fuel cell system in the laboratory environment before integrating it into the tramway," explains project manager Erik Pohl, research associate at the Professorship of Advanced Powertrains.

The Saxon consortium intends to use the project results to pave the way for the construction of new, innovative rail vehicles in Saxony. Both vehicles and system components should generate new added value, as the project results should also be used for other types of rail vehicles such as tram-trains. This approach could also be of particular interest for the Chemnitz model in the future. This model is the variant of a light rail network used in the Chemnitz region to link tramways and railroads.

The "HyTraGen" project is funded by the Federal Ministry for Digital and Transport as part of the "National Innovation Program Hydrogen and Fuel Cell Technology Phase 2".

“Waste comes in many forms, and it is and remains an issue even in times of digitalization,” says Prof. Dr. Matthias Thürer, who heads the Professorship of Factory Planning and Intralogistics at Chemnitz University of Technology. “Given the current global context, which is characterized by increasing uncertainty and ever higher costs, the exchange on how to better manage organizations is particularly important. Lean Thinking provides a comprehensive philosophy, but also requires innovative educators.”

Against this background his Professorship organizes the 10th European Lean Educator Conference (ELEC). It will take place from September 25th to 27th at Chemnitz University of Technology. The high-profile conference brings together leading lean management experts that aim at making processes better and possibly cheaper. The focus is on the latest insights from practice, and the exchange of experiences within science as well as between academic institutions, industry and public services. An industry tour and social events round off the official program, consisting of keynotes, sessions and workshops. Researchers, teachers, coaches, company representatives and anyone interested are invited to attend.

Conference website: www.lean-educator.eu

Background of lean management

It is becoming increasingly difficult for high-wage countries to maintain living standards. There is the inevitable globalization, an aging population and the lack of skilled workers. “It is therefore no coincidence that greater efficiency and effectiveness is called for in production and administration. Many organizations are trying to solve the challenges with new (digital) technologies. They overlook the fact that a technology is only as good as its application. Otherwise, the supposed solution creates new digital waste. The key to more efficient and effective processes lies in process design,” explains Thürer. This is exactly where lean management comes into play.

The Professorship of Factory Planning and Intralogistics at Chemnitz University of Technology is bringing the production management community back to its roots in West Saxony. The professorship is organizing the 43rd Advances in Production Management Systems (APMS) conference together with the Chair of Logistics at the West Saxon University of Applied Sciences Zwickau. World-renowned thought leaders share their latest research results and discuss pressing questions about current changes in the areas of intelligent manufacturing, production management, production planning and control, supply chain management and Industry 4.0 - also against the background of artificial intelligence.

The APMS will take place from September 8th to 12th, 2024 in Chemnitz, the European Capital of Culture 2025. The venue is the Carlowitz Congress Center. The conference includes keynote speeches, panels to discuss academic results, and workshops in which participants integrate theory and practice. Industrial tours and social events are also planned. The event is sponsored by the International Federation of Information Processing (IFIP). Anyone interested can find topics, important deadlines, the call for papers and registration information at https://www.apms-conference.org/.

“New technologies are changing the way how we organize processes and work. At the same time, complementary performance results, such as sustainability and safety, are becoming increasingly important. The focus at APMS 2024 will therefore be on solutions for volatile, uncertain, complex and ambiguous production environments.” says Prof. Dr. Matthias Thürer, who heads the Professorship of Factory Planning and Intralogistics at Chemnitz University of Technology since March 2023.

Prof. Dr. Ralph Riedel, Professor of Logistics at the West Saxony University of Zwickau, adds: “We are proud that, after stations in Europe, Asia and the USA, we are able to bring APMS back to Germany, especially to Eastern Germany. The world’s leading specialist conference brings together international experts in production systems and logistics from science and industry. It is an excellent networking opportunity for researchers from our region.”

Production management: Origins in West Saxony

Production management is changing, driven on the one hand by external factors and on the other hand from within companies - today and in the past. The first textbook on production management, De Re Metallica, was published as early as 1556 in West Saxony by Georgius Agricola. Production management as a science begins with Scientific Management, a management model developed by Frederick W. Taylor at the beginning of the 20th century. Over the past 110 years (since 1911), a variety of developments have resulted in a variety of different management systems, including the Henry Ford Production System and the Toyota Production System. Today we are talking about Industry 4.0 and Industry 5.0.

During hip surgeries, physicians often have to exert significant force. At the same time, precision is crucial at the operating table. Dr. Mario Lorenz and Sebastian Knopp, research associates at the Professorship of Production Systems and Processes (headed by Prof. Dr. Martin Dix) at Chemnitz University of Technology, have further developed a virtual operation simulator that allows surgeons to realistically train the necessary force and precision for hip implant procedures. The researchers aimed to provide sensory perceptions to the surgeons as close as possible to those experienced during a real surgery, such as the resistance of bone during sawing and scraping. The combination of virtual reality and specialized haptic devices now makes this possible. "The technical base used has the potential to revolutionize the entire areas of training and further education for joint replacement surgeries," says Lorenz.

Surgeons can feel real forces and resistances during the virtual operation

"We can simulate not only the milling of the hip socket but all five main steps of the hip implant surgery," adds Knopp. These include sawing off the femoral head, milling and inserting the hip socket implant, rasping the inside of the femur, and finally, implanting the stem. The haptic feedback is provided by a haptic device specially developed for this application by HAPTION GmbH. For sawing and milling, the Chemnitz scientists built a handpiece that realistically simulates the vibrations during processing. Additionally, the researchers developed their own impaction device and have applied for a patent, as the surgeons need to exert such great forces during implant insertion, bone rasping, and stem implantation that neither a robot nor the haptic device would have been suitable.

"We conducted biomechanical measurements and found that the impaction device must withstand impulses of 22 kilonewtons during surgical training," says Lorenz. For these experiments on body donors, both the experimental setup and the measuring technology had to be completely redeveloped. This work was carried out in collaboration with researchers from the Centre for Research on Musculoskeletal Systems(ZESBO) at University of Leipzig and the Division of Macroscopic and Clinical Anatomy at Medical University of Graz. The University of Bremen developed new haptic rendering methods for two-handed tasks in the various surgical steps and adapted them for the operation of the impaction device.

Experts can be connected remotely

The finished training system can now be used either as a complete training or in individual modules with three different difficulty levels. Moreover, there are multiplayer modes for the collaboration of remotely located physicians, where one person operates, another instructs, and more viewers can attend the same virtual operation room. In the VR simulation, texts and images guide through the individual surgical steps. These were designed and implemented by FAKT Software GmbH with support from YOUSE GmbH based on the clinical knowledge of Zeisigwaldkliniken Bethanien Chemnitz. In addition, FAKT Software GmbH has created the possibility to record the surgical training, play it back later, and practice the surgical steps again with audio commentary. CAT Production GmbH, under the guidance of private lecturer Dr. med. habil. Dirk Zajonz, senior consultant at Zeisigwaldkliniken Bethanien Chemnitz, visually optimized the 3D models of a virtual patient.

Comprehensive user study ensures acceptance of the medical VR application

Orthopedic surgeons were involved in the entire development process. They formulated detailed requirements and evaluated the final training simulator in a comprehensive user study to ensure the acceptance of the medical VR application. Seventeen participants – from medical students to chief physicians – took part in the evaluation. "We are very pleased that the evaluation of our application at the Zeisigwaldkliniken in Chemnitz went so well and that the test persons assess our system as useful, meaningful, and realistic, even though there is still potential for improvement," says Lorenz.

The "DynamicHIPS" project was funded by the Federal Ministry of Education and Research with approximately 442,000 euros from May 2020 to April 2023 at Chemnitz University of Technology and received two Science Awards from the German Institute for Virtual Realities.

On September 7, 2023, representatives of Elmos Semiconductor SE presented the "Advantest T2000", a high-quality testing machine for semiconductor production, as a donation to the Professorship of Circuit and System Design at Chemnitz University of Technology (TUC). The machine was handed over to Prof. Dr. Ulrich Heinkel, head of the Professorship of Circuit and System Design, in the presence of Prof. Dr. Uwe Götze, Vice President for Transfer and Academic Qualification at TUC.

This equipment allows, among other things, students at the Faculty of Electrical Engineering and Information Technology at TUC to try out programs for the comprehensive testing of chips under practical conditions. In semiconductor production, the chips are tested rigorously under high time pressure during production - for example, by activating all functions and checking for functionality. This step is essential for quality assurance and subsequent use, including in smartphones, screens, and electromobility. The faster this step is completed, the more efficient the production process is.

"The T2000 IPS was used as a laboratory testing machine and was deployed in production. Thanks to this donation, students at the Faculty of Electrical Engineering and Information Technology at TUC will gain insight into the thinking and working methods of test engineers," says Markus Boll, Test Development Engineer from Elmos Semiconductor SE, which has a long-standing partnership with the Professorship of Circuit and System Design. "We wish the Professorship of Circuit and System Design, particularly under the direction of Prof. Dr. Ulrich Heinkel, a lot of fun with testing as well as practical training," adds Volker Fabiunke, Director of Test Development at Elmos.

"This example of close cooperation between industry and science shows how the study and research conditions at our university can be further improved with the help of practical partners. This enables the qualification of urgently needed specialists, in this case for the semiconductor industry, at a high level," says Prof. Dr. Uwe Götze from TUC.

"The testing machine donated today complements the equipment of our test laboratory and offers the opportunity to create even more practical study conditions on site, thereby improving the quality of our degree programs in the fields of microelectronics and microsystems technology and further developing the studies in this field," says Prof. Dr. Ulrich Heinkel.

Saxony is unique when it comes to research and growth in the fields of materials and production engineering as well as process and recycling technology. This expertise, combined with support from funding measures for structural change, will also benefit Lusatia. In the CircEcon – Green Circular Economy research cluster, TU Dresden, TU Bergakademie Freiberg, Chemnitz University of Technology and Zittau/Görlitz University of Applied Sciences will work together to develop groundbreaking solutions for the challenges of the circular economy and to strengthen the competitiveness in Lusatia. The circular economy is a key factor in the sustainable transformation of industry and society.

With the constituent meeting of the Steering Committee for CircEcon on August 16, the Rectors of TU Dresden, TU Bergakademie Freiberg, TU Chemnitz and Zittau/Görlitz University of Applied Sciences took the decisive step to set the course for the sustainable development of the region with a joint scientific facility. The planned location for the research center is the "Schwarze Pumpe" industrial park. The federal and state governments will fund the project with EUR 108 million.

Prof. Ursula M. Staudinger, Rector of TU Dresden, commented, “Bringing together the expertise of the universities of applied sciences and universities in Chemnitz, Dresden, Freiberg and Zittau/Görlitz in a joint facility will result in an outstanding pooling of specialist knowledge and technology that will facilitate the development of groundbreaking solutions to the challenges of the circular economy while also strengthening the competitiveness of the region.”
