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 ...

The computer as microscope

18-Jan-2017

Protein switches are active everywhere in the body and often affect the generation of diseases. Thanks to a special method, researchers from Bochum have gained new insights into their workings. Using a combination of infrared spectroscopy and computer simulation, researchers at Ruhr-Universität ...

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 ...

Sustainable chemical processes

01-Apr-2016

In order to manufacture chemical products in the industry, a high energy input is required, which consumes mainly our fossil resources. At RUB, two scientists are researching into a resource-efficient and, consequently, sustainable approach. Prof Dr Robert Kourist from the junior research group ...

Assessing quality of flowing waters with DNA analyses

Organisms in streams and rivers shed light on quality of waters

10-Jul-2015

The quality of waters can be assessed using of the organisms occurring therein. This approach often results in errors, because many species look alike. Therefore, new methods focus on DNA analyses instead. Biologists at the Ruhr-Universität Bochum (RUB) have optimised the process so that they are ...

Water ice renders short-lived molecule sustainable

12-Feb-2015

“Antiaromatic compounds” is what chemists call a class of ring molecules which are extremely instable – the opposite of the highly stable aromatic molecules. Because they exist for mere split seconds, they can only be detected by extremely demanding, ultrafast methods. Together with colleagues ...

Water movement as detection aid for molecules

26-Sep-2014

Water is a ubiquitous solvent in all life sciences – sometimes referred to as the "matrix of life". Contrary to earlier assumptions, it is not a passive witness of biochemical processes; rather, it participates in them actively. By influencing the movement of water molecules surrounding their ...

q&more – the networking platform for quality excellence in lab and process

The q&more concept is to increase the visibility of recent research and innovative solutions, and support the exchange of knowledge. In the broad spectrum of subjects covered, the focus is on achieving maximum quality in highly innovative sectors. As a modern knowledge platform, q&more offers market participants one-of-a-kind networking opportunities. Cutting-edge research is presented by authors of international repute. Attractively presented in a high-quality context, and published in German and English, the original articles introduce new concepts and highlight unconventional solution strategies.
