Individual silver nanoparticles observed in real time

31-Jul-2018

The particles have an antibacterial and anti-inflammatory effect. They are used in medicine and the food industry. But little is known about their mode of action and degradation so far. Chemists at Ruhr-Universität Bochum have developed a new method of observing the chemical reactions of ...

Olfactory receptors have more functions than merely smell perception

19-Jul-2018

Olfactory receptors can be found in all types of human tissue, and they may become of great interest in the field of medical science. Numerous studies to date have shown that olfactory receptors are relevant not only for smell perception, but that they also play a significant physiological and ...

Robust and inexpensive catalysts for hydrogen production

12-Apr-2018

Hydrogen gas is considered a possible future source of energy and can be produced from water using platinum catalysts and electricity. However, alternative catalysts made of cheaper and more readily available materials with equally high efficiency are barely known. Electrodes without precious ...

How the brain might compensate stress during learning

08-Mar-2018

Friend or foe, chequered or striped – the brain divides everything around us in categories. How the brain manages this task under pressure. When people have to assess a situation within seconds, it helps them to draw on learned categories. Psychologists from the Ruhr-Universität Bochum examined ...

Self-healing catalyst films for hydrogen production

29-May-2017

Chemists at the Centre for Electrochemical Sciences at Ruhr-Universität Bochum have developed a catalyst with self-healing properties. Under the challenging conditions of water electrolysis for hydrogen production, the catalyst material regenerates itself, as long as the components required for ...

Spicy molecule inhibits growth of breast cancer cells

22-Dec-2016

Capsaicin, an active ingredient of pungent substances such as chilli or pepper, inhibits the growth of breast cancer cells. This was reported by a team headed by the Bochum-based scent researcher Prof Dr Dr Dr habil Hanns Hatt and Dr Lea Weber, following experiments in cultivated tumour cells. ...

How solvent molecules cooperate in reactions

10-Oct-2016

Molecules from the solvent environment that at first glance seem to be uninvolved can be essential for chemical reactions. This has been shown by researchers studying the formation of an ether in pure solvents and in their mixtures. They explained the underlying mechanisms in detail using ...

Synthesis of hydrogen: Enzymes assemble themselves in the test tube

01-Jun-2016

Researchers from Bochum have engineered a hydrogen-producing enzyme in the test tube that works as efficiently as the original. The protein - a so-called hydrogenase from green algae - is made up of a protein scaffold and a cofactor. The latter is the reaction centre where the substances that ...

Switching specific G-protein-coupled signalling pathways on and off

12-Apr-2016

Blue on, yellow off: using different-coloured light, researchers are able to switch signalling pathways in the brain on and off. Researchers in Bochum have utilised light-sensitive proteins from nerve cells of the eye – so-called melanopsins – to switch on specific signalling pathways in brain ...
