How ice particles promote the formation of radicals

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 in combination with ice particles, such as those found ...

How water fleas detect predators

Water fleas of the genus daphnia detect via chemical substances if their predators, namely Chaoborus larvae, are hunting in their vicinity. If so, they generate defences that make them more difficult to consume. The signalling ...

Noble metal-free catalyst system as active as platinum

Industry uses platinum alloys as catalysts for oxygen reduction, essential in fuel cells and metal-air batteries, among other applications. Expensive and rare, that metal imposes tight restrictions on manufacture. Researchers ...

A protective shield for sensitive enzymes in biofuel cells

An international team of researchers has developed a new mechanism to protect enzymes from oxygen as biocatalysts in fuel cells. The enzymes, known as hydrogenases, are just as efficient as precious metal catalysts, but unstable ...

Security gaps identified in internet protocol IPsec

In collaboration with colleagues from Opole University in Poland, researchers at Horst Görtz Institute for IT Security (HGI) at Ruhr-Universität Bochum (RUB) have demonstrated that the internet protocol IPsec is vulnerable ...

Infrared sensor as new method for drug discovery

Using an infrared sensor, biophysicists at Ruhr-Universität Bochum (RUB) have succeeded in analysing quickly and easily which active agents affect the structure of proteins and how long that effect lasts. Thus, Prof Dr. ...

New chemical compounds make catalysts more efficient

A team from the Chair of Inorganic Chemistry II at Ruhr-Universität Bochum has developed new chemical compounds that make catalysts more efficient. With their electronic and spatial properties, the new class of what are ...

Security gaps identified in LTE mobile telephony standard

By abusing security weaknesses in the LTE mobile telephony standard, attackers are able to identify which web pages a user visits and to reroute him to a scam website. This is the result of a study carried out by security ...

Why bioelectrodes for energy conversion are not stable

Researchers at the Ruhr-Universität Bochum have discovered why bioelectrodes containing the photosynthesis protein complex photosystem I are not stable in the long term. Such electrodes could be useful for converting light ...
