Apps such as Uber are an important mobility feature in many big cities. Driving others from A to B in their own car has become a job for many people. However, many drivers complain that their income is too low. In May 2019, the US television station ABC reported how Uber drivers at Washington airport artificially inflated the price of the service by all going offline at the same time. Within a few minutes, the price of the service had risen by 13 dollars, which almost doubled the amount.  
How exactly does this strategy work and when is it used? This is what Dr. Malte Schröder and Professor Marc Timme from the Chair for Network Dynamics at the Center for Advancing Electronics Dresden (cfaed) and the Institute for Theoretical Physics at TU Dresden have been investigating alongside PhD students David-Maximilian Storch and Philip Marszal.

Broad spectrum. Novel hybrid material proves an efficient photodetector

Press release from HZDR, 9 April, 2020

Published on in PRESS RELEASES

Physicists of HZDR and TU Dresden have developed a photodetector, which is completely based on layers of metal-organic frameworks. Since this compound can detect and transform a broad range of light wavelengths into electrical signals, it could become a novel detector material. Image: HZDR / Juniks

Digital cameras as well as many other electronic devices need light-sensitive sensors. In order to cater for the increasing demand for optoelectronic components of this kind, industry is searching for new semiconductor materials. They are not only supposed to cover a broad range of wavelengths but should also be inexpensive. A hybrid material, developed in Dresden, fulfills both these requirements. Himani Arora, a physics PhD student at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), demonstrated that this metal-organic framework can be used as a broadband photodetector. As it does not contain any cost-intensive raw materials, it can be produced inexpensively in bulk.

[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.
