Scientists from the “AM Bridge 2019” research project at TU Darmstadt are revolutionizing steel construction. Their goal: a 3D-printed steel bridge over flowing water. The demonstration project on the site of the Department of Civil and Environmental Engineering at Lichtwiese has now been completed. The plan: Welding a complete bridge over water.

But the people in Darmstadt wanted more: Instead of printing individual components, the robots welded the bridge as a whole, on site and over water. The idea was realized with the help of the “CMT Cycle Step” welding process. What's special about it is that welding spots can be produced in any size and precisely reproduced.

New test chamber enables simulation of processes in the body

Teams from the departments of mechanical engineering and biology at the TU Darmstadt observe the growth of cells on bone implants. For this purpose, they have developed a special test chamber that is intended to make some animal experiments superfluous.

Hip and knee joints made of titanium, vertebral bodies made of plastic and other bone implants have already relieved many patients of pain. However, some people who wear such endoprostheses suffer from complications, for example if the artificial bone does not grow in properly. “What exactly happens in the body after implantation is still unclear,” says materials scientist Anne Martin from the Institute of Materials Science at the Department of Mechanical Engineering at Darmstadt Technical University. Together with her former colleague Markus König and researchers from Bianca Bertulat's Department of Biology, she has developed a model system that simulates the first days after the insertion of a bone implant.

Scientists evaluate the potential of materials for magnetic cooling.

For the year 2060, futurologists expect a paradigm shift in global energy consumption: for the first time, mankind will then use more energy for cooling purposes than for heating. The increasing penetration of cooling applications in our everyday lives has resulted in a steadily growing ecological footprint. New processes such as magnetic cooling could minimize this impact on the climate and the environment. Researchers at the TU Darmstadt and the Helmholtz Centre Dresden-Rossendorf (HZDR) have examined the materials currently in question for their suitability in more detail. The result of their work is the first systematic material library with important parameters, which they have now published in the journal Advanced Energy Materials.

Materials scientists at the TU Darmstadt want to reinvent the material ceramics. To do this, they intervene in its atomic structure. The German Research Foundation (DFG) is funding this as part of a highly endowed Reinhart Koselleck project.

When you think of ceramics, you think of dishes or sharp knives. However, Professor Jürgen Rödel from the Department of Non-Metallic Inorganic Materials at TU Darmstadt believes that much more can be gained from the hard and brittle material than the huge selection of sensors or capacitors already known.

Researchers use machine elements as sensors

Tobias Schirra, who specializes in product development and machine elements, spent one and a half years researching further development together with his colleague from the department, Georg Martin. They have turned a standard rolling bearing into a sensor bearing that can be used to measure loads and lubricant film thickness, among other things. The new development is intended to help “estimate the time of the next maintenance or when the component needs to be replaced,” reports Schirra. The service life can thus be predicted better and operating procedures can be designed more smoothly.

The TU researchers have not installed any additional measuring sensors, but instead use the electrical properties of the rolling bearing itself as a sensor. Tobias Schirra explains the principle in simple terms: “We hold a kind of voltage measuring device to the bearing rings. The advantage of TU technology: ”Other bearings on the market equipped with extra sensors require more space. Our development, on the other hand, does not take up more space than a conventional bearing,“ he emphasizes.

At the Hannover Exhibition, the TU researchers presented their technology and established contacts with companies. Initial reactions, Mr. Schirra and Mr. Martin report, were already encouraging. ”Thanks to the support of the Pioneer Fund, we can now concentrate on further development work," they say. The support ensures a full-time position for the next one and a half years.

TU successful in the ideas competition “Real Laboratories of the Energy”

We are happy and congratulate our member Prof. Jens Schneider and his team:

Federal Minister of Economics Peter Altmaier today announced the winners of the “Real Laboratories of the Energy Turnaround” competition, including the TU with its DELTA project outline. The aim is to test sustainable energy technologies under real conditions and on an industrial scale. Nationwide, the Federal Ministry of Economics and Energy (BMWi) awarded prizes to 20 consortia, which can now submit their applications for funding in the coming months. The BMWi is providing 100 million euros annually for this purpose.

As consortium leader of the DELTA project, Professor Jens Schneider from the Institute for Statics and Design at the TU, in close cooperation with the Institute for Production Management, Technology and Machine Tools (PTW) under the direction of Professor Eberhard Abele, is working on energy-optimised neighbourhoods with the aim of reducing energy consumption and carbon dioxide emissions in urban neighbourhoods. To this end, Darmstadt is linking several types of neighbourhood, from industry, commerce and education to housing, with network infrastructures in the areas of electricity, heat, gas, communications and transport in order to reduce energy requirements as far as possible and use energy efficiently.

The TU also took part in the ideas competition with the Institute for Mechatronic Systems in Mechanical Engineering, the Department of Electrical Energy Supply using Renewable Energies and the Construction Management and Technical Operations Department.

Flexible sun protection made of perforated textiles

Professor Stefan Schäfer demonstrate the prototype
Professor Stefan Schäfer demonstrate the prototype

Sun protection systems for buildings typically are available as louvre systems (venetian blinds) and as textile blinds (roll-down blinds). Venetian blinds do not illuminate the room optimally and require more maintenance effort especially as outdoor systems. Conventional textile roll-down blinds provide better illumination of rooms because of diffuse blinding effects, but cannot completely prevent glare effects and do not allow individual adjustment of light transmission.

A sun protection system which promises a high adaptability with low production and maintenance costs at the same time is planned to be developed within this research project. For this purpose, special patterns are laser-cutted on textile surfaces which effects 3D deformation under tensile stress. The effect is possible through textile “joints“ within the perforated surface only.

Therefore, stepless adaption is doable by controlled insertion of tensile stress. This offers the possibility to react to changing light conditions individually.

At the same time, the deformation needs no additional components, which extends the life span of the system positively. read more

How squares become curves

Researchers at TU Darmstadt develop shell structures from prefabricated brick parts

For centuries, vaulted brick constructions were an established method of bridging large rooms and spans without columns. Due to the great effort involved in their manufacture, this type of supporting structure is no longer used today. A research team at Darmstadt Technical University has now developed a process that enables the cost-effective production of multiple-curved brick shells from flat prefabricated parts.

Thin load-bearing constructions are called planar structures. If these are additionally curved, one speaks of shells. Shell structures made of bricks are highly load-bearing, aesthetic and can cover large spans with small cross-sections. However, their manufacture is material- and personnel-intensive, above all because a substructure in the form of a full-surface so-called falsework is required for construction. This determines the curvature and can only be removed after complete completion, as brick shell structures are only fully load-bearing with the last stone. This type of load-bearing structure is therefore practically never used.

In a research project of the Institute for Constructive Design and Building Construction (KGBauko) at the Department of Civil and Environmental Engineering at the TU Darmstadt, a team led by Alexander Pick within the framework of the ZukunftBau research initiative has investigated whether and how brick shells can be produced economically – for example by using prefabricated parts. The work was carried out in two stages: first digitally on the computer, then with bricks in field trials. The design and calculations of the brick shell were carried out with the aid of a computer model. A prototype 15 meters long and 11.5 centimeters thick with multiple curved geometry was designed on the computer as a 3D model. A complex, static and constructionally rather unfavourable geometry was deliberately chosen in order to prove the efficiency of the principle. read more

Washing sludge as an alternative raw material

TU researchers develop novel expanded granulate from waste products

Sand and gravel are important raw materials for a wide range of building materials, which are extracted by surface or wet mining. They are washed in processing plants and classified according to grain size. In this process, a fine grain fraction that cannot be used directly is separated as a suspension, the so-called washing sludge. This water-solid mixture, which also contains clay particles, remains in the mining area and is no longer used.

“Central Europe is estimated to produce 50 million tons of washing sludge every year, which has so far been almost completely untapped”, says Professor Eddie Koenders, head of the Institute of Construction and Building Materials (WiB) at TU Darmstadt. Of the 15 million tons produced annually in Germany, only about 0.7 percent would be used.

As part of a research project funded by the Arbeitsgemeinschaft industrieller Forschungsvereinigungen (AiF) and the Zentrales Innovationsprogramm Mittelstand (ZIM), a team at WiB is developing a production process as well as possible raw material compositions for the manufacturing of expanded granules from washing sludge. The expanded granules are fine-pored, mineral, spherical structures with a closed-pored surface that can be produced in various sizes.

Ulrike Kramm, Christina Birkel and Bai-Xiang Xu organized the 680th WE-Heraeus-Seminar on ‘Materials Development for Automotive Propulsion’ that took place in Bad Honnef from Oct 14th to Oct 17th 2018. About 60 scientists with physics, materials science, chemistry and engineering background came together to talk about materials challenges in battery, catalysis and syn-fuel research. Particularly unusual was the large number of female scientists that accounted for > 50 % of the participants, which was realized by providing flexible child care options.

The overall seminar was financed by the WE-Heraeus foundation that also offered great support for the organisation of the meeting. During the seminar, a discussion table was sponsored by the PMP profile area with the focus on career perspectives, work life balance and similarities/differences in scientific careers in- or outside Germany.

Prof. Dr. Markus Biesalski

The DFG supports the research package “Geometric and Chemical Structure of Functional Papers”, in which 7 sub-projects jointly carry out basic research on functional papers over the next 3 years. In addition, the DFG is funding further 5 individual projects focusing on the same topic for the same period. The 11 researchers at TU Darmstadt, supported by 2 colleagues from Freiburg University and TU Grenoble, have now joined forces to promote functional papers from material understanding to product innovation.

In the subprojects of the association, in which 14 doctoral students and 2 postdocs will work, the long-term goal addresses the fundamental understanding or structure-property relations of (polymer) functionalized paper, in order to explore the hitherto largely untapped potential of paper as a functional material. The subprojects will address the following key questions:

• How can a high orientation of the fibers in the paper sheet be adjusted and can an orientation of the fibers also be switched by external stimuli?

• How do fiber orientation and functionalization affect mechanical properties of paper and how do functionalized paper webs behave in the presence of liquids?

• Can polymers be incorporated into the pore structure as functional modules in such a way that they impart elastically deformable properties to paper, chemically stable paper webs are accessible or, after conversion, thermally stabilized, paper-derived materials result?

• Can the functionalization of paper fibers with polymers be better understood across scales across model systems?

• What design principles must be followed when polymer modifying papers and thermally converting them to obtain the aforementioned properties?

• In experimental work, can theoretical models be used to accompany such design principles and, ideally, to make them predictable?

From profile area PMP, the following scientists participate in this initiative as PI:

Markus Biesalski (Spokesperson), Hans-Joachim Kleebe, Regine von Klitzing (Vice-Spokesperson), Ralf Riedel, and Bai-Xiang Xu.

Funktionsmaterialien für Energiespeicher

Im neuen LOEWE Schwerpunkt „FLAME – Fermi Level Engineering Antiferroelektrischer Materialien für Energiespeicher und Isolatoren“ wird erforscht, wie sich die Eigenschaften von Funktionsmaterialien über deren elektronische Struktur einstellen lassen. Koordinator ist Professor Andreas Klein. Zwölf Arbeitsgruppen aus den Fachbereichen Material- und Geowissenschaften, Chemie sowie Elektrotechnik und Informationstechnik werden Funktionswerkstoffe etwa für Kondensatoren mit hoher Energie- und Leistungsdichte entwickeln. Diese ermöglichen eine effizientere Wandlung und Übertragung elektrischer Energie aus erneuerbaren Quellen und in der Elektromobilität. Das Projekt wird begleitet von Unternehmen aus der Funktionskeramik und der Elektrotechnik sowie von der Tongji-Universität in Shanghai, einer der Partneruniversitäten der TU Darmstadt.

Der auf andere Materialien und Anwendungsbereiche übertragbare Forschungsansatz basiert darauf, optimierte elektronische Strukturen einzustellen („Fermi Level Engineering“), die mit Computersimulationen vorhergesagt und experimentell verwirklicht werden. Das ermöglicht eine zielgenaue Einstellung der Eigenschaften bei verkürzten Entwicklungszeiten.

Nukleare Photonik und schaltbare Funktionsmaterialien – diese Forschungsthemen werden zwei neue LOEWE-Schwerpunkte an der TU Darmstadt ab 2019 intensiv bearbeiten. Beide Schwerpunkte werden jeweils mit 4,65 Millionen Euro gefördert; die Laufzeit beträgt vier Jahre. Dies gab Hessens Wissenschaftsminister Boris Rhein heute im Rahmen der Förderentscheidungen für die 11. Staffel des LOEWE-Programms (Landesoffensive zur Entwicklung Wissenschaftlich-ökonomischer Exzellenz) bekannt.

Wir freuen uns und gratulieren Dr. Leopoldo Molina-Luna aus der Gruppe Geomaterialwissenschaft (Angewandte Mineralogie) von Prof. Kleebe zur Förderung durch den Europäischen Forschungsrat (ERC).

Drei Forschungsprojekte an der TU Darmstadt werden vom Europäischen Forschungsrat (ERC) als exzellente und innovative Grundlagen- und Pionierforschung mit ERC Starting Grants gefördert. Insgesamt fließen rund 5,2 Millionen Euro an drei Nachwuchswissenschaftlerinnen und -wissenschaftler.

Das Projekt „FOXON“ von Dr. Leopoldo Molina-Luna beschäftigt sich mit der Transmissionselektronenmikroskopie (TEM). Diese hat in den letzten zwanzig Jahren einen rasanten Fortschritt gemacht. Aberrationskorrektoren, die auf Forschungen des früheren Darmstädter Physikprofessors Harald Rose zurückgehen, drückten die räumliche Auflösung bis auf 50 Pikometer (pm). Elektronenkanonen mit hoher Helligkeit, verbesserte Energieauflösung des Elektronenenergieverlustes (EEL) und hocheffiziente energiedispersive Röntgendetektoren ermöglichen die 2D-Abbildung von Zusammensetzungen und chemischen Bindungsinformationen. „FOXON“ führt diese Entwicklungen fort.

Ziel ist die Anwendung einer operando TEM-Methode, um die Korrelation von elektrischem Verhalten, Struktur und chemischer Zusammensetzung von oxidbasierten Funktionsmaterialien simultan unter einem angelegten elektrischen Feld zu untersuchen. Pixel- und ultraschnelle Elektronen-Detektoren ermöglichen dabei die Erfassung eines Beugungsmusters für jeden Abtastpunkt und den Zugriff auf Informationen, die weit über die Möglichkeiten der Standard-STEM-Detektoren hinausgehen. Ständig steigende Rechenleistung und die Entwicklung von Werkzeugen zur effizienten Simulation von TEM-Experimenten sowie die ab-initio-Berechnung von Materialeigenschaften verbessern die Modellierung und Interpretation von TEM-Daten. Der nächste Schritt besteht darin, Reize wie elektrische Spannung und Temperatur in-situ auf ein funktionales Gerät anzuwenden und strukturelle und chemische Veränderungen mit höchstmöglicher Auflösung zu beobachten.

Die Zielverbindungen gehören zu der Familie der so genannten MAX-Phasen, von denen bereits mehr als 70 Vertreter – jedoch bisher keine eisenhaltigen – synthetisiert wurden. Die möglichen Mitglieder dieser Materialklasse mit den chemischen Zusammensetzungen Fe2AlC und Fe2SiC versprechen sehr spannende magnetische Eigenschaften.

Im Projekt „Wet chemical synthesis of nanoscale and magnetic ternary carbides“ sollen diese über nasschemische Syntheserouten nanoskalig (im Milliardstel-Meter-Bereich) das erste Mal hergestellt werden. Magnetische Nanopartikel finden in diversen biomedizinischen Bereichen Anwendung, wie z.B. bei der gezielten Arzneimittelabgabe und der Magnetresonanztomographie. Neben den magnetischen Eigenschaften stehen daher außerdem die Biokompatibilität und Stabilität im Fokus; in diesen Bereichen können die genannten Carbid-Nanopartikel von großem Vorteil sein. Dadurch berührt das Projekt wichtige Bereiche aus der Chemie, den Lebens- und Materialwissenschaften.

Mit dem Exploration Grant ermöglicht es die Boehringer Ingelheim Stiftung herausragenden Grundlagenforscherinnen und Grundlagenforschern aus Biologie, Chemie und Medizin, neue Ideen zu bearbeiten. Die Förderung kann für Personal- und Sachmittel verwendet werden.

Alexander von Humboldt-Fellowship for Experienced Researcher for Prof. Yu

We congratulate Prof. Dr. Zhaoju from Xiamen University, China. She received the Alexander von Humboldt-Fellowship for Experienced Researcher. Prof. Yu will stay in the Dispersive Solid Group of the Materials Science Department from July 1, 2017- June 30, 2018. Her research interest is devoted to single-source-precursor route towards carbon nanophase containing SiCN ceramic nanocomposites with multifunctional electromagnetic properties.

An “ERC Starting Grant” (1.5 million euro) goes to Sascha Preu, Assistant Professor for terahertz systems technology.

Taking full advantage of the terahertz spectrum

Professor Sascha Preu and his team want to combine optical and terahertz technologies, in order to develop new photonic vector network analysers and photonic spectrum analysers that are far more powerful than the existing electronic terahertz systems.

The terahertz range (100 GHz-10 THz) lies between infrared radiation and microwaves, that is, on the boundary between electronics and optics. Despite the great advances made over the last two decades, this is still the least used range of the electromagnetic spectrum. The extremely high cost of systems to characterise circuits and components is not the only factor making it difficult to develop efficient components and systems. This is the starting point for Professor Preu’s project, that intends to cover a considerable part of the THz spectrum. The project focuses in particular on photonic systems that can also analyse THz chips. This should help make it easier to develop THz circuits and compact THz systems.

New technologies must be explored, which can allow wideband photonic components to be integrated on a chip and which can be used for system integration. Photonic circuits have multiple advantages compared to conventional metallic circuits – such as far lower losses at high frequencies.

Cool research – Scientists receive research funding from the European Union

Three TU Darmstadt scientists were awarded substantial grants from the European Research Council (ERC) for their excellent projects.

The outstanding research of Professor Oliver Gutfleisch on the substitution of critical raw and other materials for energy technologies is acknowledged with an “ERC Advanced Grant” (2.5 million euro).

Energy-efficient cooling technologies

Oliver Gutfleisch is researching into permanent magnets with a drastically reduced rare earth content, for use in electric motors and wind turbines, and also into new materials for innovative solid-state based cooling technologies. The key issue preoccupying Gutfleisch is: How can the earth’s population cope with the challenge of having to invest increasing amounts of energy in cooling systems in the 21st century. “Keeping cool is fundamental to a higher standard of living, and many countries are quick to install ever greater cooling capacities based on non-sustainable and less-efficient technologies”, says Gutfleisch.

Gutfleisch thinks that the best opportunities for a new, energy-efficient cooling technology quite possibly lie in using the magnetocaloric effect. “Admittedly, the materials used so far are based on critical metals. And current cooling concepts do not yet exploit the full potential of the materials.” This is why Gutfleisch and his team are planning to use so-called Heusler materials in a fundamentally new process regime that capitalises on the effects of hysteresis. Should the tests prove successful, this could revolutionise cooling technology right down to product level, and greatly reduce the global energy consumption for cooling systems.

Das Loewe-Projekt BAMP! – Bauen mit Papier ist seit dem 1. Januar 2017 ein vom Land Hessen geförderter Forschungsschwerpunkt an der TU Darmstadt. Er beschäftigt sich in einem interdisziplinären Ansatz mit der Entwicklung von Grundlagen zum Einsatz von Papier als Baumaterial.

Papier ist kostengünstig herstellbar, besteht überwiegend aus nachwachsendem Rohstoff, bietet bezogen auf das Eigengewicht sehr gute Festigkeitseigenschaften und ist verhältnismäßig einfach chemisch zu funktionalisieren. Für Anwendungen wie Fassadenelemente mit hoher Wärmedämmwirkung oder als Schalenstrukturelemente fehlen heutigen Produkten jedoch die dreidimensionale Verformbarkeit, die Witterungs- und Langzeitbeständigkeit und andere Eigenschaften.

Ziel von BAMP! ist es, die noch vorhandenen Defizite bezüglich der Grundlagen zu eliminieren, Synergien aus den beteiligten Disziplinen zu nutzen und eine systematische Entwicklungsmethodik entlang der Materialverarbeitungskette zu erarbeiten. Dafür sind neue Gestaltungsansätze erforderlich, bekannte Materialeigenschaften sind auf die neuen Erfordernisse hin anzupassen. Auch die Fertigungstechnik muss weiter entwickelt werden.

Im Rahmen dieser Lehrveranstaltung nehmen wir Sie mit in aktuelle Forschungsansätze und bieten eine einzigartige Möglichkeit, einen Produktentstehungsprozess näher kennen zulernen und mitzugestalten.
