Sharper than ever: Physicists make molecular vibrations more detectable

The new method will improve the understanding of interactions in molecular systems and to further develop simulation methods

22-Sep-2022

In molecules, the atoms vibrate with characteristic patterns and frequencies. Vibrations are therefore an important tool for studying molecules and molecular processes such as chemical reactions. Although scanning tunnelling microscopes can be used to image individual molecules, their vibrations ...

Precise control of catalytic reactions

“Using this nanoreactor, it is possible to synthesize complex drugs that could not be synthesized inside the body until now”

16-Sep-2022

Various chemical reactions occur one after another in cells, and life is maintained as each step of the reaction is regulated without error. Recently, a Korean research team has developed a dual-catalyst system that can precisely control catalytic reactions like cells. A POSTECH research team led ...

Making and breaking of chemical bonds in single “nanoconfined” molecules

Research team investigates reactivity of single molecules under controlled microscopic conditions

14-Sep-2022

Researchers around the world are working to develop efficient materials to convert CO2 into usable chemical substances – work that is particularly pressing in view of global warming. A team from the University of Göttingen, Germany, and the Ulsan National Institute for Science, South Korea, has ...

A new rule for orbital formation in chemical reaction discovered

07-Sep-2022

Squeaky, cloudy or spherical - electron orbitals show where and how electrons move around atomic nuclei and molecules. In modern chemistry and physics, they have proven to be a useful model for quantum mechanical description and prediction of chemical reactions. Only if the orbitals match in ...

Recycling Greenhouse Gases

Novel perovskite catalysts could be used wherever methane and carbon dioxide are produced simultaneously

05-Sep-2022

CO2 and methane can be turned into valuable products. But until now the catalysts required for such reactions quickly lose their effectiveness. TU Wien has now developed more stable alternatives. Wherever the production of harmful greenhouse gases cannot be prevented, they should be converted ...

Tip tricks control reactions in a single molecule

Pulses from an atom-sharp tip enable researchers to break and form chemical bonds at will

31-Aug-2022

Chemical reactions often produce messy mixtures of different products. Hence, chemists spend a lot of time coaxing their reactions to be more selective to make particular target molecules. Now, an international team of researchers has achieved that kind of selectivity by delivering voltage pulses ...
