Researchers succeed in synthesizing a molecule that should not actually exist

03-Jun-2022

How many atoms can an aromatic ring have if it contains only two electrons? The answer has recently been changed: five! For the first time, a team from chemistry has succeeded in synthesizing and describing a five-membered aromatic compound - an important class of substances in chemistry - by ...

The conversion to a metal only takes 20 femtoseconds

16-Feb-2021

A group of researchers from the Fritz Haber Institute of the Max Planck Society and the Humboldt-Universität zu Berlin have found out that semiconductors can be converted to metals and back more easily and more quickly than previously thought. This discovery may increase the processing speed and ...

Scientists photographed, for the first time, individual atoms floating less than a thousandth of a millimeter above a light-conducting glass fiber

06-Aug-2020

The first photograph of a single trapped atom represented a milestone for quantum research. This breakthrough was made possible because the atom was captured in a vacuum using electric fields and held far from surfaces whose scattered light could blind the camera. Scientists at Humboldt ...

Discovery lays the foundation for recycling of yet non-recyclable plastics

15-Aug-2018

Robust plastics are composed of molecular building-blocks, held together by tough chemical linkages. Their cleavage is extremely difficult to achieve, rendering the recycling of these materials almost impossible. A research team from the Humboldt-Universität zu Berlin (HU) developed a molecule, ...
