With AI against material wear

13-Aug-2024 - Friction and wear lead to considerable economic losses in industry. The complexity of technical systems makes it difficult to predict damage accurately. Dr. Stefanie Hanke, new Professor of 'Materials Engineering' at the Faculty of Engineering at the University of Duisburg-Essen, is developing an ...

New Material Paves the Way to On-Chip Energy Harvesting

09-Jul-2024 - Researchers from Germany, Italy, and the UK have achieved a major advance in the development of materials suitable for on-chip energy harvesting. By composing an alloy made of silicon, germanium and tin, they were able to create a thermoelectric material, promising to transform the waste heat of ...

Refrigerator cools by flexing artificial muscles

The new technology is based on an incredibly simple principle

04-Apr-2024 - There is room for just one small bottle in the world’s first refrigerator that is cooled with artificial muscles made of nitinol, a nickel-titanium alloy. But the mini-prototype that the team led by professors Stefan Seelecke and Paul Motzki will be presenting at the Hannover Messe from 22 to 26 ...

Golden future for thermoelectrics

Record breaking material

20-Sep-2023 - Researchers at TU Wien discover excellent thermoelectric properties of nickel-gold alloys. These can be used to efficiently convert heat into electrical energy. Thermoelectrics enable the direct conversion of heat into electrical energy - and vice versa. This makes them interesting for a range of ...

Shape memory for nano-sized objects

Shape memory objects as thin as twenty nanometers produced for the first time: Broad range of applications

21-Mar-2023 - Researchers at ETH Zurich achieved a shape memory effect for the first time with objects that are only a few nanometers in size. This can be used to manufacture tiny machinery and robotic devices on the nanoscale. Alloys that can return to their original structure after being deformed have a ...

Slim steel - strong and safe

A material made from a few readily available components is very strong in tension and is nevertheless highly formable

31-Jan-2023 - Until now, developers of steels have had to make a choice: Either they increase the tensile strength of the material and usually accept that their material becomes relatively brittle. Or they rely on the fact that the steel can be strongly stretched and thus absorb a lot of energy in the event of ...

Changing shapes at the push of a button

A single piece of material can take the place of entire systems of sensors, regulators and actuators

04-Jan-2023 - Programmable materials are true shapeshifters. They can change their characteristics in a controlled and reversible way with the push of a button, independently adapting to fit new conditions. They can be used, for example, to make comfy chairs or mattresses that prevent bedsores. To produce ...

High entropy alloys: structural disorder and magnetic properties

"High-entropy alloys are an extremely diverse and exciting class of materials”

26-Oct-2022 - High-entropy alloys (HEAs) are promising materials for catalysis and energy storage, and at the same time they are extremely hard, heat resistant and demonstrate great variability in their magnetic behaviour. Now, a team at BESSY II in collaboration with Ruhr University Bochum, BAM, Freie ...
