New Material Breaks World Record Turning Heat into Electricity

15-Nov-2019

A new type of material generates electrical current very efficiently from temperature differences. This allows sensors and small processors to supply themselves with energy wirelessly. Thermoelectric materials can convert heat into electrical energy. This is due to the so-called Seebeck effect: ...

Researchers develop new 3D printing for the direct production of nanostructures

14-Nov-2019

A team from Graz University of Technology succeeded in using the FEBID method to produce complex 3D-printed nano-components for the first time without additional support structures. In the nanometer range, complex, free-standing 3D architectures are very difficult to produce in a single step due ...

Atomic images reveal unusually many neighbors for some oxygen atoms

22-Oct-2019

The identification of new chemical bonds is crucial for the design of new material structures. A team led by Jani Kotakoski at the University of Vienna and Jannik Meyer at the University of Tübingen has found unexpected new configurations of oxygen and nitrogen in graphene. Direct images of the ...

Solving the Mystery of Quantum Light in Thin Layers

17-Oct-2019

A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna). It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material ...

The fast dance of electron spins

Chemists investigate the interactions of metal complexes and light

07-Oct-2019

Metal complexes show a fascinating behavior in their interactions with light, which for example is utilized in organic light emitting diodes, solar cells, quantum computers, or even in cancer therapy. In many of these applications, the electron spin, a kind of inherent rotation of the electrons, ...

2000 atoms in two places at once

A new record of quantum superposition

30-Sep-2019

The quantum superposition principle has been tested on a scale as never before in a new study by scientists at the University of Vienna in collaboration with the University of Basel. Hot, complex molecules composed of nearly two thousand atoms were brought into a quantum superposition and made to ...

From years to days: Artificial Intelligence speeds up photodynamics simulations

Scientists use deep neural networks to achieve simulations on long time scales

16-Sep-2019

The prediction of molecular reactions triggered by light is to date extremely time-consuming and therefore costly. A team led by Philipp Marquetand from the Faculty of Chemistry at the University of Vienna has now presented a method using artificial neural networks that drastically accelerates ...

Milestones on the Way to the Nuclear Clock

Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition

13-Sep-2019

If you want to build the most accurate clock in the world, you need something that “ticks” very fast and extremely precise. In an atomic clock, electrons are used, which can be switched back and forth between two different states in a very precisely defined way. Even more precise, however, would ...

Single atoms as catalysts

03-Sep-2019

Incorporating individual metal atoms into a surface in the right way allows their chemical behavior to be adapted. This makes new, better catalysts possible. They make our cars more environmentally friendly and they are indispensable for the chemical industry: catalysts make certain chemical ...
