Innovative computational method unveils high-performance ceramics for extreme environments

Research team identifies hundreds of representatives of a particularly heat-resistant class of materials

31-Jan-2024 - An international research team has developed a method for rapidly discovering new types of materials that function at extremely high temperatures of several thousand degrees Celsius. These high-performance ceramics could one day form the basis for more robust coatings, batteries and ...

A “gold standard” for computational materials science codes

23-Jan-2024 - Physicists and materials scientists can choose from a whole family of computer codes that simulate the behavior of materials and predict their properties. The accuracy of the results obtained by these codes depends on the employed approximations and chosen numerical parameters. To verify that the ...

Machine learning takes materials modeling into new era

Deep learning approach enables accurate electronic structure calculations at large scales

11-Jul-2023 - The arrangement of electrons in matter, known as the electronic structure, plays a crucial role in fundamental but also applied research such as drug design and energy storage. However, the lack of a simulation technique that offers both high fidelity and scalability across different time and ...

On the Hunt for Ultra-Thin Materials Using Data Mining

Study identifies extensive set of novel 2D materials

14-Mar-2022 - Two-dimensional (2D) materials possess extraordinary properties. They usually consist of atomic layers that are only a few nanometers thick and are particularly good at conducting heat and electricity, for instance. To the astonishment of many scientists, it recently became known that 2D ...

How to cool more efficiently

Scientists break new ground in future refrigeration

03-Dec-2020 - In the journal Applied Physics Reviews, an international research team from the University of Barcelona, the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), and TU Darmstadt report on possibilities for implementing more efficient and environmentally friendly refrigeration processes. For this ...

Tomorrow's coolants of choice

Scientists assess the potential of magnetic-cooling materials

18-Sep-2019 - Later during this century, around 2060, a paradigm shift in global energy consumption is expected: we will spend more energy for cooling than for heating. Meanwhile, the increasing penetration of cooling applications into our daily lives causes a rapidly growing ecological footprint. New ...

Frustrated materials under high pressure

Researchers modify magnetic behavior of exotic materials

26-Apr-2019 - People are not the only ones to be occasionally frustrated. Some crystals also show frustrations. They do so whenever their elementary magnets, the magnetic spins, cannot align properly. Cesium copper chloride (Cs2CuCl4) – or CCC for short – is a prime example of frustrated materials. In this ...

Miniature X-ray source using wiggling electrons

02-Oct-2009 - A team at the Laboratory for Attosecond Physics of Ludwig Maximilian's University of Munich and Max Planck Institute of Quantum Optics in Garching has succeeded in reducing X-ray sources of typically several kilometres in size to the dimensions of a dining table. This involved a new method using ...
