You can't really see them, but you can follow the energy flow like in a flip book: Physicists from the University of Duisburg-Essen (UDE) have investigated the energy transfer in a metal insulator material and published their results in "Physical Review B". In the long term, they could contribute to solving the heat problem in microelectronics through targeted material design.
The Sparkasse Duisburg has now honoured four students and four doctoral students* for their outstanding achievements. Two of them are members of working groups in our Materials Chain. The prizes are endowed with 2,000 and 1,000 euros respectively.
Normal movements without trembling or cramping - this is what brain pacemakers allow people with Parkinson's disease to do. High quality and long-term stability of the implanted electrodes are essential in order to minimize follow-up operations. To this end, researchers at the University of Duisburg-Essen (UDE) want to coat the implants with metal nanoparticles and thus improve the contact between implant and tissue. Dr. Brian Giera from the Livermore National Laboratory (USA), currently a Mercator Fellow at the UDE, is also involved.
State-of-the-art functional materials, such as strong permanent magnets for use in wind turbines and electric motors, or magnetic materials for efficient cooling, are needed to transition to a low emissions future. The German Science Foundation (DFG) has therefore granted €12 million for a new Collaborative Research Center (CRC) called “HoMMage”. This centre will begin its first 4 years on 1st of January 2020 at Technische Universität Darmstadt and UDE.
Dr. Chin Ken Wong is a fellow of the Alexander von Humboldt Foundation (AvH). Since October, he has been supported by the Foundation's Postdoctoral Fellowship. The chemist has been a research assistant at the Gröschel Working Group since October. He is researching the development of artificial building blocks for the transport of substances in the body.
On November 20, Dr. Franziska Muckel will be honored for her outstanding dissertation. She is awarded this year's doctoral prize by the Rhine-Ruhr Electrical and Electronic Manufacturers' Association (VDE). She received her doctorate in March 2019 from the UDE in the working group of Prof. Gerd Bacher.
"MaNaCa" is about the targeted destruction of cancer cells with magnetic nanoparticles. But at the same time, it is a mentoring program for the Academy of Sciences in Armenia: The project on two levels, in which physicists from the Center for Nanointegration (CENIDE) of the University of Duisburg-Essen (UDE) are significantly involved, is funded by the European Union with 800,000 €.
The wagon is packed, once again the courier points the reader at the loading area, checking: everything on board, nothing forgotten. Printed radio labels without chips should make this possible in the future. The DruIDe* project, in which four Materials Chain members from the University of Duisburg-Essen (UDE) are playing a leading role, will not only result in a new technology, but also in two start-ups that will take care of the market launch.
Around 120 representatives from industry and science met on 9 October for the 6th RUHR Symposium at the Fraunhofer inHaus Centre on the UDE Duisburg campus. Functional magnetic materials were the focus of the event, at which State Secretary Oliver Wittke promoted the electric car completely "made in Germany".
Precious metal-free nanoparticles could serve as catalysts for the production of hydrogen from water. Because they are so small, their properties are difficult to determine. Materials Chain chemists have now developed a new process with which they can characterize individual precious metal-free nanoparticle catalysts.
More than 40 experts in physics, chemistry and materials science from 12 countries meet in “Die Wolfsburg” Academy in Mülheim an der Ruhr on 2-4 October 2019. They share their research results and discuss new concepts in nanomagnetism and its applications, like energy-efficient computing and magnetic refrigeration.
Enzymes use cascade reactions to produce complex molecules from comparatively simple raw materials. Materials Chain researchers have copied this principle.
A suitable culture medium, some heat and the computer grows all by itself: a processor made of special bacteria could process considerably more data for the same size than its silicon counterpart. Scientists from the Materials Chain at the University of Duisburg-Essen (UDE) report in the journal Nature Communications about their discovery of magnetic oscillations inside bacteria.
Expert advice? Priceless for a career. Many of them will be given to young scientists from the materials sciences on September 16 at the 1st Materials Chain Early Career Researchers' Forum of the UA Ruhr in Dortmund. Registration is possible online.
Cooled food and drugs are very important for many humans. Simultaneously, keeping them cold harms the environment. Prof. Qiming Zhang explores how optimal chilling reduces the climate change. The winner of the Humboldt-Research-Award is guest of Prof. Dr. Doru C. Lupascu at the UDE-Institute of Materials Science.
And yet they move: An international team of scientists involving physicists from the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) has observed a new phenomenon: They have generated standing waves – which travel. The results of their research have been published in the scientific journal "Physical Review B" including videos of the effect.
Graphene does not like to be compressed – instead it forms twisted domains during epitaxial growth on an iridium substrate.
Colloquially, the term “quantum jump” is used to describe a tremendous development. In fact, it is the smallest change of state that can still be traced. Physicists from the Collaborative Research Center 1242 at the University of Duisburg-Essen (UDE) have now succeeded in measuring every single jump by optical means and drawing conclusions about the dynamics of the electrons inside a quantum dot. The journal Physical Review Letters reports on this in its 122ndissue.
The tiny rings that chemists at the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) create in the laboratory are as small as a bacterium. Self-organized, individual polymer chains form the flexible structures that can even squeeze themselves through cell membranes. This would enable them to deliver active substances in a very targeted manner. The renowned scientific journal ACS Nano reports on this in its current issue.
Not much is possible without catalysts: More than 80% of all chemically manufactured products undergo a catalytic step during their production. The active material is usually platinum or another precious metal, so production is correspondingly expensive and requires several steps. Physicists at the University of Duisburg-Essen (UDE) have now filed a patent application for a process that produces highly active and long-term stable catalyst material in a single step.
Precious metals are often efficient catalysts. But they are expensive and rare. However, it has so far been difficult to determine how efficient non-precious metal alternatives are. A team including Prof. Dr. Kristina Tschulik from the Ruhr-Universität Bochum, Prof. Dr. Stephan Schulz (UDE) and colleagues from Dresden published together in the Journal of the American Chemical Society.
Phase-change materials are used in the latest generation of smartphones enabling higher storage densities and energy efficiency. However, to date it has not been possible to study what happens at the atomic level during this process. In a paper published today in Science, a group of scientists led by researchers from the University of Duisburg-Essen and the European XFEL in Germany, show that changes of the chemical bonding mechanism in the liquid phase enables data storage in these materials.
They look like interlocking egg cups, but a hen's egg is 100,000 times as thick as one of the miniature cups: Scientists at the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) have made polymers to form themselves into tiny cups on their own. They could, for example, be used to remove oil residues from water. The scientists have published their results in the journal "Angewandte Chemie".
To improve car engines, produce nanomaterials or design rocket engines, it is essential to understand combustion processes. Professor Hai Wang from Stanford University (USA) is an expert in this field. As a winner of the prestigious Research Award of the Alexander von Humboldt Foundation, he is currently a guest researcher at the NanoEnergieTechnikZentrum (NETZ) of the University of Duisburg-Essen (UDE).
Generating electricity from heat differences or mechanical energy has been possible for a long time. But the materials required are usually expensive, rare or toxic. Physicist Dr. Anna Grünebohm from the University of Duisburg-Essen (UDE) researches harmless and easily available alternatives. She has succeeded in recruiting one of the coveted Emmy Noether junior research groups, and will be funded with more than €1.3 million for six years.
While politicians are struggling for mandatory solutions to limit carbon dioxide (CO2) emissions, Dr Corina Andronescu is researching a complementary solution – the electrochemical conversion of CO2into usable fuels such as methanol, called "Dream Reaction". In December, she was appointed junior professor for electrochemical catalysis at the University of Duisburg-Essen (UDE).
