Shedding light on comet Chury’s unexpected chemical complexity

The secret was hidden in the dust

07-Jul-2022

A team of researchers led by the University of Bern has for the first time identified an unexpected richness of complex organic molecules at a comet. This was achieved thanks to the analysis of data collected during ESA’s Rosetta mission at comet 67P/Churyumov-Gerasimenko, also known as Chury. ...

Anionic Nickel

Nickel-catalyzed cross-coupling of aromatic ethers proceeds via a nickelate anion

26-Oct-2021

Metal catalysts are widely used in the production of drugs, dyes, adhesives, and plastics. Researchers have now discovered an intriguing property of nickel as a catalyst: it is able to catalyze the coupling of aromatic hydrocarbons in its anionic form, the nickelate ion. In this form, the two ...

Breaking the rules of chemistry unlocks new reaction

Scientists have broken the rules of enzyme engineering to unlock a new method for creating chemical reactions that could unlock a wide range of new applications - from creating new drugs to food production

03-Dec-2020

In their paper published in Nature Catalysis, Professor Francesca Paradisi and Dr. Martina Contente of the University of Nottingham and the University of Bern show a new method to produce chemical molecules more efficiently through a new one step reaction in the enzyme. Professor Paradis is ...

Fuel cells for hydrogen vehicles are becoming longer lasting

Electrocatalyst without a carbon carrier developed

26-Aug-2020

An international research team led by the University of Bern has succeeded in developing an electrocatalyst for hydrogen fuel cells which, in contrast to the catalysts commonly used today, does not require a carbon carrier and is therefore much more stable. The new process is industrially ...

Recycling carbon dioxide from the ocean

Floating power plants

11-Jun-2019

Paper, tin cans, glass - the world recycles as much as possible. So why not declare the greenhouse gas carbon dioxide (CO2) a recycling product as well? Liquid fuels based on carbon will continue to play an important role in the future - despite international efforts to reduce them. So it seems ...

Atmospheric chemistry on paper

26-Jul-2016

Normally computers speed up calculations. But with his new pen-and-paper formula Kevin Heng of the University of Bern gets his results thousands of times faster than using conventional computer codes. The astrophysicist calculates the abundances of molecules (known as atmospheric chemistry) in ...

Rosetta’s mass spectrometer ROSINA detected argon at comet Churyumov-Gerasimenko

29-Sep-2015

The mass-spectrometer ROSINA on ESA’s comet probe Rosetta has for the first time detected the noble gas argon in the coma of 67P/Churyumov-Gerasimenko. This measurement adds to the debate about the role of comets in delivering various «ingredients» to Earthsuch as water. Comets are considered to ...

GKSS scientists refute argument of climate skeptics

The global increase of warmer years is no accident

13-Jan-2009

Between 1880 and 2006 the average global annual temperature was about 15°C. However, in the years after 1990 the frequency of years when this average value was exceeded increased. The GKSS Research Centre asks: is it an accident that the warmest 13 years were observed after 1990, or does this ...
