How acids behave in ultracold interstellar space

12-Jun-2019

Solvated acids tend to release a proton. However, they display more complex behaviour under space conditions. Bochum-based researchers from the Cluster of Excellence Ruhr Explores Solvation (Resolv), together with cooperation partners from Nijmegen, have investigated how acids interact with water ...

Applying precious metal catalysts economically

17-May-2019

Precious metal nanoparticles of platinum and gold are excellent catalysts. But they are expensive and rare. This new method makes it possible to save material. Researchers at Ruhr-Universität Bochum and the Fritz Haber Institute Berlin have developed a new method of using rare and expensive ...

New class of catalysts for energy conversion

08-May-2019

“The theoretical possibilities seem almost too good to be true,” says researcher Tobias Löffler. Numerous chemical reactions relevant for the energy revolution are highly complex and result in considerable energy losses. This is the reason why energy conversion and storage systems or fuel cells ...

Monitoring the lifecycle of tiny catalyst nanoparticles

06-May-2019

Since they are so tiny, it is difficult to investigate single nanoparticles. However, this is exactly what researchers are aiming for in order to tailor their properties. A novel approach: particle at the stick. Nanoparticles can be used in many ways as catalysts. To be able to tailor them in ...

Improving the lifetime of bioelectrodes for solar energy conversion

29-Apr-2019

The key to a long life for bioelectrodes lies in an oxygen-free environment. The use of proteins involved in the photosynthetic process enables the development of affordable and efficient devices for energy conversion. However, although proteins such as photosystem I are robust in nature, the use ...

Catalysts for controlled cascade reactions

01-Apr-2019

It is difficult to convert carbon dioxide or nitrogen oxides into useful or harmless substances. Wolfgang Schuhmann wants to find a way and is being helped to do so by the EU. Professor Wolfgang Schuhmann intends to produce useful platform chemicals from harmful gases on an industrial scale using ...

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 ...

Examining silver nanoparticles in natural environments

28-Feb-2019

Thanks to their antibacterial properties, the particles are used in many products. Their effect on the environment is largely unexplored. This is mainly due to the lack of suitable analytical methods. Researchers from the Resolv Cluster of Excellence at Ruhr-Universität Bochum have developed a ...

How ice particles promote the formation of radicals

Chemistry in clouds

10-Dec-2018

Certain molecules with fluorine, chlorine or bromine, together with water, can release harmful substances into the atmosphere. The production of chlorofluorocarbons, which damage the ozone layer, has been banned as far as possible. However, other substances can also tear holes in the ozone layer ...

How a crystal is solvated in water

The solvation process is of fundamental importance for chemistry – but is very difficult to observe

22-Nov-2018

How a molecule from a solid crystal structure is solvated in a liquid solvent has been observed at a molecular level for the first time by chemists at Ruhr-Universität Bochum. The process is too fast to decipher at room temperature. The team from the Ruhr Explores Solvation (Resolv) Cluster of ...
