Old Mystery Solved: a "New Kind of Electrons"

Why do certain materials emit electrons with a very specific energy?

20-Nov-2020

It is something quite common in physics: electrons leave a certain material, they fly away and then they are measured. Some materials emit electrons, when they are irradiated with light. These electrons are then called "photoelectrons". In materials research, so-called "Auger electrons" also play ...

Metal-organic frameworks become flexible

Materials science: Combined efforts of experiment and simulation pave the way to new applications.

19-Nov-2020

Materials consisting of inorganic and organic components can combine the best of two worlds: under certain circumstances, the so-called MOFs – short for metal-organic frameworks – are structured in the same order as crystals and are at the same time porous and deformable. This opens up the ...

Photons in a can

A new way to design materials

16-Nov-2020

Crystal symmetry is one of the decisive physical attributes that determines the properties of a material. In particular, the behaviour of an electron is largely affected by the symmetry of the crystal which in turn governs the fundamental behaviour of the material, such as its conductive or ...

Nano coatings with many functions

Materials scientists synthesize nanoscale gradient copolymers with contradictory properties for the first time

05-Nov-2020

Materials that simultaneously have contrasting properties – for example, they are soft on the one hand and hard on the other, the transition is gradual - could enable completely new applications like gradual anti-reflective lenses. In nature, such merging properties are indeed common, for example ...

Analysis system enables targeted investigation of antiviral surfaces for material developers

Use of real-time polymerase chain reaction to test antiviral effectiveness

28-Oct-2020

The need for everyday objects with antiviral surfaces is high due to the COVID 19 pandemic. It is known that the material composition of an object has an influence on the viability of viruses on surfaces. This is where the work of the Fraunhofer IFAM comes in: In cross-disciplinary research ...

Rare glassy metal discovered during quest to improve battery performance

Materials scientists made an astonishing discovery that could open the door to better batteries, faster catalysts and other materials science leaps

19-Aug-2020

Scientists from Idaho National Laboratory and University of California San Diego scrutinized the earliest stages of lithium recharging and learned that slow, low-energy charging causes electrodes to collect atoms in a disorganized way that improves charging behavior. This noncrystalline "glassy" ...

"Simulation microscope" examines transistors of the future

"We have created one of the largest databases of transistor materials"

12-Aug-2020

Since the discovery of graphene, two-​dimensional materials have been the focus of materials research. Among other things, they could be used to build tiny, high-​performance transistors. Researchers at ETH Zurich and EPF Lausanne have now simulated and evaluated one hundred possible materials ...

How can you perforate an atomic layer of material and leave the one underneath intact?

The Art of Making Tiny Holes: Scientists developed a technique for processing surfaces on an atomic scale

04-Aug-2020

Nobody can shoot a pistol bullet through a banana in such a way that the skin is perforated but the banana remains intact. However, on the level of individual atomic layers, such a feat has now been achieved - a nano-structuring method has been developed at TU Wien (Vienna), with which certain ...

A new synthesis method for three-dimensional nanocarbons

Connecting carbon by catalysis to create octagonal structures

04-Aug-2020

A team of scientists led by Kenichiro Itami, Professor and Director of the Institute of Transformative Bio-Molecules (WPI-ITbM), has developed a new method for the synthesis of three-dimensional nanocarbons with the potential to advance materials science. Three-dimensional nanocarbons, ...

Self-healing soft material outsmarts nature

New stretchable material entirely recovers its structure and properties at the blink of an eye – and it can do this over and over again

30-Jul-2020

A soft material that heals itself instantaneously is now reality. A team of scientists at the Max Planck Institute for Intelligent Systems and at Pennsylvania State University tune the nanostructure of a new stretchable material in such a way that it now entirely recovers its structure and ...
