Research on Semiconductors: Light Weakens Magic Nano Clusters

15-Dec-2020

They are known as "magic sized nano clusters" because they have special properties: The particles consist of only a few atoms, but since they are arranged in a special crystal structure, they are extremely stable. Unless you expose them to light. Scientists from the Center for Nanointegration ...

Catalyst Material from the Laser Lab

Industrial Relevance Proven

06-Oct-2020

In catalysts, more surface area usually equals more activity. And hardly anything offers more surface than structures made of nanoparticles. Scientists from the Center for Nanointegration (CENIDE) at the UDEhave shown that it makes sense in economic terms to produce catalytically highly active ...

3D Laser Printing in Color

Seasoning with Nanosilver

02-Sep-2020

Ventilation grilles in aircraft cabins, serial components in cars and lately even mascara brushes: The industry has been using laser-based 3D printers for several years now when precision and good mechanical properties are required. However, these printers are expensive, large and print only in ...

Superconduction: Cuprate-like behavior in a nickel-oxide film

Two-dimensional electron gas discovered

21-Jul-2020

Superconductors transmit electric current without loss at any distance and play an important role in quantum computers and medical imaging. But the stars among the electrical conductors work exclusively at extremely low temperatures. Since the discovery of high-temperature superconducting ...

New Form of Microscopy Developed

Breakthrough in nanooptics

28-Apr-2020

The duration of their snapshot relates to one second as one second relates to the age of the universe: In a joint collaboration with Australian Scientist Tim Davis and the Group around Harald Gießen (University of Stuttgart), Physicists from CENIDEhave developed ultrafast vector microscopy as a ...

Catalyst deposition on fragile chips

17-Feb-2020

Electrocatalysts can help to obtain chemicals from renewable raw materials or to use alternative energy sources. But testing new catalysts brings challenges. Researchers at the Ruhr-Universität Bochum (RUB) and the University of Duisburg-Essen have developed a new method of depositing catalyst ...

From 2D crystal to 1D wire

Unexpected behaviour of the material

31-Jan-2020

No volume, not even a surface: a one-dimensional material is like a wire and has properties that are completely different to its 3D counterpart. Physicists at the University of Duisburg-Essen (UDE) have now discovered a system that, at warmer temperatures, forms self-organized wires consisting of ...

Self-organizing molecules: Nanorings with two sides

26-Jul-2019

The tiny rings that chemists at the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) create in the laboratory are as small as a bacterium. Self-organized, individual polymer chains form the flexible structures that can even squeeze themselves through cell membranes. ...

Production of catalyst in one single step

Patent pending for process

17-Jul-2019

Not much is possible without catalysts: More than 80% of all chemically manufactured products undergo a catalytic step during their production. The active material is usually platinum or another precious metal, so production is correspondingly expensive and requires several steps. Physicists at ...

Self-organizing molecules: Cups with attoliter volume

22-May-2019

They look like interlocking egg cups, but a hen's egg is 100,000 times as thick as one of the miniature cups: Scientists at the Center for Nanointegration (CENIDE) at the University of Duisburg-Essen (UDE) have made polymers to form themselves into tiny cups on their own. They could, for example, ...
