In the active centre of carbon dioxide conversion

Scientists reveal the features of efficient carboxylase enzymes

12-Jul-2019

In order to overcome the climate crisis, two measures are required: The reduction of carbon dioxide (CO2) emissions, and removal of CO2 from the earth atmosphere. The latter is the goal of Tobias Erb's research group at the Max Planck Institute for Terrestrial Microbiology in Marburg. Their ...

Experimental mini-accelerator achieves record energy

Coupled terahertz device significantly improves electron beam quality

12-Jul-2019

Scientists at DESY have achieved a new world record for an experimental type of miniature particle accelerator: For the first time, a terahertz powered accelerator more than doubled the energy of the injected electrons. At the same time, the setup significantly improved the electron beam quality ...

Testing chemicals without animal testing on rodents

Replacement method with locusts to test whether chemicals cause neurological developmental disorders in children

11-Jul-2019

In recent years, the number of neurological developmental disorders in children has increased. Epidemiological data suggest that lifestyle factors and chemicals used in our environment contribute to this. Scientists from the Institute of Physiology and Cell Biology at the University of Veterinary ...

Charge transfer within transition-metal dyes analysed

11-Jul-2019

Transition-metal complexes in dye-based solar cells are responsible for converting light into electrical energy. A model of spatial charge separation within the molecule has been used to describe this conversion. However, an analysis at BESSY II shows that this description of the process is too ...

Producing Graphene from Carbon Dioxide

Direct Synthesis of Technological Material Graphene from Greenhouse Gas Carbon Dioxide

10-Jul-2019

The general public knows the chemical compound of carbon dioxide as a greenhouse gas in the atmosphere and because of its global-warming effect. However, carbon dioxide can also be a useful raw material for chemical reactions. A working group at Karlsruhe Institute of Technology (KIT) has now ...
