Merck and Mulliken Center for Theoretical Chemistry Collaborate in Machine Learning Project

The three-year collaboration will focus on the development of new tools for computational chemistry modelling as well as new molecular representations


Merck announced a collaboration with the Mulliken Center for Theoretical Chemistry at the Rheinische Friedrich-Wilhelms-University of Bonn, Germany. The three-year collaboration will focus on the development of new tools for computational chemistry modelling as well as new molecular ...

Protons are probably actually smaller than long thought

Study suggests errors in the interpretation of older measurements


A few years ago, a novel measurement technique showed that protons are probably smaller than had been assumed since the 1990s. This surprised the scientific community; some researchers even believed that the Standard Model of particle physics would have to be changed. Physicists at the University ...

"Heavy" hydrogen stabilizes drugs

New method may, for instance, help to make already approved medicines even more effective


Researchers at the University of Bonn have presented a method that allows the heavier hydrogen "brother" deuterium to be introduced specifically into many different molecules. The deuterated compounds obtained in this way are more stable against degradation by certain enzymes. Drugs produced ...

Chemists design "molecular sea of flags"

Nanostructures self-assemble and cover specific surfaces: "This may allow novel catalysts to be realized"


Researchers at the University of Bonn have developed a molecular structure that can cover graphite surfaces with a sea of tiny flagged "flagpoles". The properties of this coating are highly variable. It may provide a basis for the development of new catalysts. The compounds could also be suitable ...

Kekulé's shattered dream: snakes become ladders

Researchers create novel molecules that serve as ziplines for energy


Researchers from the Universities of Bonn and Regensburg move packets of energy along a molecular ladder made of hundreds of benzene rings. Such polymers can potentially be used to design new displays based on organic light-emitting diodes, or for solar cells. The extraordinary material is now ...

New substance classes for nanomaterials

Nano spheres and diamond slivers made of silicon and germanium


Chemists at Goethe University Frankfurt have developed two new classes of materials in the field of nanomaterials and investigated them together with their cooperation partners at the University of Bonn: for the first time, they have succeeded in producing a nano sphere of silicon atoms and a ...

Thawing permafrost releases greenhouse gas from depth


In a study led by the University of Bonn, geologists compared the spatial and temporal distribution of methane concentrations in the air of northern Siberia with geological maps. The result: the methane concentrations in the air after last year's heat wave indicate that increased gas emissions ...

Bioplastics in the sustainability dilemma

Scientists investigate the factors affecting the global land use impacts and CO2 emissions of plant-based plastics


Plastics made from crops such as maize or sugarcane instead of fossil fuels are generally considered sustainable. One reason is that plants bind CO2, which compensates for the carbon released into the atmosphere when plastics are disposed. However, there is a catch: With increasing demand for raw ...

Innovations through hair-thin optical fibres

Study shows what miniaturised optical filters make possible


Scientists at the University of Bonn have built hair-thin optical fibre filters in a very simple way. They are not only extremely compact and stable, but also colour-tunable. This means they can be used in quantum technology and as sensors for temperature or for detecting atmospheric gases. The ...

Researchers develop sustainable catalysis process

Method enables sustainable oxidations related to enzyme reactions


Acetals are important chemical compounds that are used, for example, in the production of certain medical agents. A new method now makes their synthesis easier and more environmentally friendly. Chemists at the University of Bonn have developed and optimized the sustainable catalytic process. ...
