Converting biomass by applying mechanical force

15-Mar-2019

One of the greatest global challenges is the efficient use of renewable sources in order to meet the increasing demand for energy and feedstock chemicals in the future. In this context, biomass is a promising alternative to existing fossil sources such as coal or oil. Cellulose plays a decisive ...

Fixation of powder catalysts on electrodes

04-Jul-2017

Chemists at Ruhr-Universität Bochum have developed a new method to tightly fix catalyst powders on electrode surfaces. Currently, the high physical stress induced on catalyst films by gas evolving reactions hampers the application of powder based catalysts. The developed technique is potentially ...

Splitting disulphide bonds in water is more complicated than previously thought

26-Oct-2016

From a chemical perspective, splitting disulphide bonds under tensile stress is a substantially more complicated process than previously assumed. A team headed by Prof Dr Dominik Marx from Ruhr-Universität Bochum found out what happens in detail during this process - with the aid of extensive ...

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 ...

New insights into the supercritical state of water

Researchers predict terahertz spectra using computer simulations

25-Jan-2016

Using molecular dynamics simulations, researchers have analysed the properties of supercritical water. The researchers showed which structure of the hydrogen bond network is formed in different supercritical states and also simulated the relevant terahertz spectra. This approach may help in ...

New access to the interior of electronic components

Potential application: sensors for chemical substances

25-Nov-2015

An interdisciplinary team at the Ruhr-Universität Bochum has found a way of accessing the interior of transistors. The researchers have manipulated the electron gas contained within by applying resonators to generate rhythmic oscillation in the terahertz range inside. Transistors can be ...

Researchers from Kiel and Bochum develop new information storage device

14-Oct-2015

Scientists from Kiel University and the Ruhr Universität Bochum (RUB) have developed a new way to store information that uses ions to save data and electrons to read data. This could enable the size of storage cells to be reduced to atomic dimensions. But that is not the only advantage of the new ...

New method facilitates research on fuel cell catalysts

Faster design – better catalysts

12-Oct-2015

While the cleaning of car exhausts is among the best known applications of catalytic processes, it is only the tip of the iceberg. Practically the entire chemical industry relies on catalytic reactions. Catalyst design plays a key role in improving these processes. An international team of ...

New method to better understand atomic nuclei

28-Sep-2015

The precise structure of atomic nuclei is an old problem that has not been fully solved yet, and it also constitutes a current research focus in the field of natural sciences. Together with colleagues from Bonn University, physicists at Ruhr-Universität Bochum have developed an approach to carry ...
