[Press release from the TU Dresden Press Office dated 26 March 2020. The mentioned SIXONIA tech company is a start up from the cfaed Chair for Molecular Functional Materials led by Prof. Xinliang Feng. Deutsche Version unter read more]

The "Taicang High-Tech Park" near Shanghai (China) is donating 10,000 urgently needed respiratory protective masks to TU Dresden and its Carl Gustav Carus University Hospital.  

"We are extremely grateful for this gesture of friendship and this strong signal of international solidarity and I am personally deeply touched", says Prof. Hans Müller-Steinhagen, Rector of TU Dresden. "In times of need, such a humanitarian gesture has a significance that goes far beyond its mere material value."

Scientists at TU Dresden and Hasselt University in Belgium investigated the physical causes that limit the efficiency of novel solar cells based on organic molecular materials. Currently, the voltage of such cells is still too low - one reason for their still relatively low efficiencies. In their study, by investigating the vibrations of the molecules in the thin films, the scientists were able to show that very fundamental quantum effects, so-called zero point vibrations, can make a significant contribution to voltage losses. The study has now been published in the journal Nature Communications.

A team of international scientists under the lead of Francesca Moresco (Center for Advancing Electronics Dresden – cfaed at TU Dresden) and Diego Peña Gil (Center for Research in Biological Chemistry and Molecular Materials – CiQUS at University of Santiago de Compostela) has achieved a breakthrough in the field of π-electron structures research. For the first time, they synthesized a chain of twelve benzene rings, called dodecacene, which is the longest acene ever obtained to date. This was made possible by using on-surface synthesis and observed by scanning tunneling microscopy. The investigation of the properties of higher acenes also revealed an unexpected increase in the energy gap of dodecacene. The scientists have now published their results in the journal "ACS Nano".

Hermetically sealed semi-conductors

New encapsulation technique protects electronic properties of sensitive materials

Published on in PRESS RELEASES

HZDR researchers have developed a new method to protect semi-conductors made of sensitive materials from contact with air and chemicals. It becomes, thus, possible to integrate these ultra-thin layers in electronic components, without impairing their performance. Copyright: HZDR / Sahneweiß / graphicINmotion, Shutterstock

Tomorrow’s electronics are getting ever smaller. Researchers are thus searching for tiny components that function reliably in increasingly narrow configurations. Promising elements include the chemical compounds indium selenide (InSe) and gallium selenide (GaSe). In the form of ultra-thin layers, they form two-dimensional (2D) semi-conductors. But, so far, they have hardly been used because they degrade when they get in contact with air during manufacturing. Now, a new technique allows the sensitive material to be integrated in electronic components without losing its desired properties. The method, which has been described in the journal ACS Applied Materials and Interfaces (DOI: 10.1021/acsami.9b13442), was developed by Himani Arora, a doctoral candidate of physics at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR).

As part of the German government's High-Tech-Strategy 2025, the Federal Ministry of Education and Research (BMBF) is funding an interdisciplinary research group that aims to use an innovative circuit technology to solve a central problem of genetic investigation of human single cells. Medical professionals hope that such research will drastically improve the diagnosis and therapy of many serious diseases and enable the treatment of or even cure for cancer and immune diseases, for which there are currently no suitable methods available.
