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 ...

"Funnel" attracts bonding partners to biomolecule

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 ...

Efficient production of hydrogen by algae

20-Aug-2014

Microalgae need only sunlight and water for the production of hydrogen. However, in order to make hydrogen production by microalgae economically feasible their efficiency has to be increased by 1-2 orders of magnitude. In the current issue of Energy and Environmental Science scientists from the ...

Toward fuel cells built from renewable and abundant components

07-Aug-2014

In the development of fuel cells the effort of generations of scientist and engineers have led to efficient and stable catalysts based on noble metals. These catalysts have reached the required threshold in terms of performance for applications such as electric cars. However, the high costs of ...

Terahertz dance of amino acids

RUB chemists explain the fingerprint of dissolved glycine in the Terahertz range

01-Apr-2014

Chemists at the Ruhr-Universität Bochum (RUB) have, for the first time, completely analysed the fingerprint region of the Terahertz spectrum of a biologically relevant molecule in water, in this case, an amino acid. By combining spectroscopy and molecular-dynamics simulations, they rendered the ...

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.
