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 ...

Molecular telegraphy

Precisely sending and receiving single molecules

23-Nov-2020 - Researchers of the University of Graz, Austria, managed to send single molecules to a distant location and receive them from there. The study appears as the cover story in the current issue of the magazine Science. The idea of throwing and catching a ball is familiar to everyone. Now, if the ball ...

Photosynthetic microalgae as biocatalysts

The biocatalytic production of chemicals should become considerably more sustainable

06-Mar-2018 - A carpet of blue-green algae can literally ‘cloud’ the summer’s swimming pleasure at the lake. This is caused by a few strains of photosynthetically active microalgae, also known as cyanobacteria. Other harmless strains of cyanobacteria have great potential for biotechnological applications and ...

New Light On Electron Density

Measuring electron orbitals

18-Nov-2009 - For the first time, it has been possible to measure electron density in individual molecular states using what is known as the photoelectric effect. Now published in Science, this method represents a key building block in the development of organic semiconductor elements. Supported by the ...

Arsenic-containing lipids in fish oil

01-Aug-2008 - Scientists have identified a novel group of arsenic-containing compounds in fish oil that may have an unusual biosynthetic origin. Kevin Francesconi at Karl-Franzens University, Graz, Austria, and colleagues found three arsenic-containing lipids in the oil from capelin fish found in the North ...
