Researchers succeed in synthesizing a molecule that should not actually exist

03-Jun-2022

How many atoms can an aromatic ring have if it contains only two electrons? The answer has recently been changed: five! For the first time, a team from chemistry has succeeded in synthesizing and describing a five-membered aromatic compound - an important class of substances in chemistry - by ...

Shrinking Tesla technology: An application-oriented method for an unsolved problem in microelectronics

22-Feb-2022

Computers are getting smaller and smaller, just as current cell phones offer computing power similar to that of a laptop. And the trend toward miniaturization continues. Smart dust applications (tiny microelectronic devices), such as biocompatible sensor systems in the body, demand computers and ...

Research team from Chemnitz and Berlin presents new concept for more reactive copper-based catalysts

25-Oct-2021

Catalysts are used wherever chemical reactions take place. For example, in organisms during respiration, in the chemical industry during product manufacture or in the exhaust gas stream of the combustion engine. Regardless of the place of action, the same principle applies everywhere: catalysts ...

How carbon-based nanostructures can get a new functionalit

20-Apr-2021

Scientists have already been able to demonstrate that graphene nanostructures can be generated by annealing of a nanostructured silicon carbide crystal for a few years. “These two-dimensional, spatially strongly restricted carbon bands exhibit a vanishingly small electrical resistance even at ...

A lamellar lens prototype has been successfully tested at DESY

08-Oct-2014

Researchers have taken an important step towards developing a new X-ray lens made of diamond. A team of scientists from the Technische Universität (TU) Dresden and Technische Universität Chemnitz as well as from DESY have successfully tested a new lens design. The group working with DESY Leading ...

Chemnitz University of Technology presents solar panels, which are printed with special inks with electrical properties on standard paper

22-Sep-2011

These days, everyone talks about the use of solar energy for the generation of electricity. Conventional solar cells, however, use expensive materials and are manufactured under costly clean room conditions. Consequently, they can only deliver expensive electricity. Researchers at Chemnitz ...
