"Honey, I shrunk the detector"
Silicon chip (approx. 3 mm x 6 mm) with multiple detectors. The fine black engravings on the surface of the chip are the photonics circuits interconnecting the detectors (not visible with bare eyes). In the background a larger scale photonics circuit on a silicon wafer. Researchers have developed the world's smallest ultrasound detector Researchers at the Technical University of Munich (TUM) and Helmholtz Zentrum München have developed the world's smallest ultrasound detector.

New Analytical Methods for Longer-Lasting Lithium-ion Batteries
New Analytical Methods for Longer-Lasting Lithium-ion Batteries
How can the lithium-ion battery (LIB) be further improved? To answer this question, MEET scientists around Lenard Hanf developed new methods for capillary electrophoresis. For the first time, this enables a detailed analysis of the transition metal dissolution from LIB cathode materials or the current collector - such as manganese or copper.

Battery Research Centre: new international research school opened
Longer ranges for electric vehicles and the effective storage of electricity from renewable energies - these are research topics for the future which PhD students in Münster will be working on in a new international Graduate School. The research centre for "Battery Chemistry, Characterization, Analysis, Recycling and Application" (BACCARA for short) was officially opened on August 5 at the MEET Battery Research Centre at the University of Münster.

Tailored light inspired by nature
Tailored light inspired by nature
Researchers develop for the first time light fields using caustics that do not change during propagation / Study in "Nature Communications" Modern applications as high resolution microsopy or microor nanoscale material processing require customized laser beams that do not change during propagation. This represents an immense challenge since light typically broadens during propagation, a phenomenon known as diffraction.

Topological control by tuning structural chirality
Topological control by tuning structural chirality
Chiral crystals that have a distinct handedness have recently emerged as one of  the most exciting new classes of topological materials. An international research team from institutions in Germany, Switzerland, United Kingdom, and China has now demonstrated that their crystal handedness directly determines how quasiparticles propagate and scatter at impurities in such materials.

New method enables a view inside batteries
The Solid Electrolyte Interphase (SEI) inside both lithium-ion and lithium metal batteries is indispensable for successful battery cell operation and at the same time an analytical challenge. Up to now, its analysis has only been possible to a limited extent; knowledge about formation, composition, growth or reactions is incomplete.

Cherned up to the maximum
In topological materials, electrons can display behaviour that is fundamentally different from that in 'conventional' matter, and the magnitude of many such 'exotic' phenomena is directly proportional to an entity known as the Chern number. New experiments establish for the first time that the theoretically predicted maximum Chern number can be reached - and controlled - in a real material.

New insights into lithium metal technology
New insights into lithium metal technology
It is one of the key technologies for high-performance batteries of the future: the lithium metal battery (LMB). Designed for instance as solid-state battery with polymer electrolyte, it promises a significantly higher energy density than the currently common lithium-ion battery (LIB). However, it is not yet fully developed for the final commercial breakthrough and is therefore currently used by only a few pilot projects.

A fresh twist in chiral topology
Electrons in "chiral crystals", solid-state materials with definite "handedness", can behave in unexpected ways. An interdisciplinary team from research institutions in Germany and China has realized now a theoretically predicted peculiar electronic state in a chiral compound, PtGa, from the class of topological materials.

Three Research Groups, Two Kinds of Electronic Properties, One Material
An outstanding collaboration combines materials science, experimental and theoretical physics. The work paves the way to new designed materials that combine in them multiple electrical functionalities. This is the story of a unique material - made of a single compound, it conducts electrons in different ways on its different surfaces and doesn't conduct at all in its middle.

MEET - Publication galvanic corrosion
MEET - Publication galvanic corrosion
In addition to high purchase costs and the still underdeveloped charging infrastructure, the limited range is one of the biggest obstacles to switching to electric vehicles. Industry and science are therefore working intensively on developing batteries with a higher energy density and making them suitable for series production.

Photonic chips made possible by light-emitting silicon-germanium alloys For the past 50 years, researchers around the globe have been looking for a way to make lasers with silicon or germanium. A team from the Technical University of Eindhoven (TU/e) and the Technical University of Munich (TUM) has now succeeded in developing a light-emitting, silicon-germanium alloy.

Activating palladium catalysis by light: teaching an old transition metal new tricks
Activating palladium catalysis by light: teaching an old transition metal new tricks
In the production of compounds, chemists have the fundamental goal of finding strategies that are most selective and avoid waste products. Breakthroughs in this area serve, among other things, to drive industrial innovation and drug development. In this context, allylic substitution reactions using catalysts made of so-called transition metals have already led to significant advances in science.

Strange metal behavior in a pure ferromagnetic Kondo lattice
Strange metal behavior in a pure ferromagnetic Kondo lattice
In the quest to harness quantum mechanics for new kinds of materials and new kinds of technologies, physicists are turning to the study of 'quantum materials' where the effects of quantum mechanics give rise to new forms of collective behavior. Normal metals, such as copper, gold or aluminum are well understood in terms of the quantum mechanics of individual electrons, and their resistivity depends linearly on temperature due to scattering of electrons by the vibrations of the lattice of atoms.

Spider silk: A malleable protein provides reinforcement
09/26/2019 Scientists from the University of Würzburg have discovered that spider silk contains an exceptional protein. It generates high bonding strength by making use of an amino acid scientists have hitherto paid little attention to. Why are the lightweight silk threads of web spiders tougher than most other materials' Scientists from the Universities of Würzburg and Mainz teamed up to find answers to this question.

Physicists Develop "Time Machine" for Materials Science
Physics experiments are often time-consuming and expensive. Sometimes scientists do not realize until the very end that they have been using the wrong calibration for measurements the whole time. What if there were a way to go back in time to the start of the experiment and re-examine the data? Researchers at Martin Luther University Halle-Wittenberg (MLU), Freie Universität Berlin, and the Technical University of Munich (TUM) hope to create a machine that would make that possible.

05/23/2019 A great success for Würzburg's physics department: its Collaborative Research Centre was rated as excellent and is now entering its second funding phase. The German Research Foundation is providing 12 million euros for this purpose. In 2015, physicists at Julius-Maximilians-Universität (JMU) Würzburg in Bavaria, Germany, succeeded in establishing a new Collaborative Research Centre in Würzburg.
