Strange things happen when a crystal gets split in two

05-Feb-2018

When a crystal is broken along certain directions the atoms reorganize in amazing ways. Researchers in Vienna have watched this happen, and have learned to control it. The remarkable strength of ionic crystals is easily explained at the atomic scale: Positively and negatively charged atoms sit ...

Artificial materials atom-by-atom

29-Mar-2017

Researchers at Aalto University have manufactured artificial materials with engineered electronic properties. By moving individual atoms under their microscope, the scientists were able to create atomic lattices with a predetermined electrical response. The possibility to precisely arrange the ...

Sorting machine for atoms

13-Feb-2017

Physicists at the University of Bonn have cleared a further hurdle on the path to creating quantum computers: in a recent study, they present a method with which they can very quickly and precisely sort large numbers of atoms. Imagine you are standing in a grocery store buying apple juice. ...

Molecular selfie reveals how a chemical bond breaks

Proton is seen escaping the molecule

24-Oct-2016

Imagine what it would be like to watch how the individual atoms of molecules rearrange during a chemical reaction to form a new substance, or to see the compounds of DNA move, rearrange and replicate. Such capability would give unprecedented insight to understand and potentially control the ...

Ultrasensitive sensors made from boron-doped graphene

04-Nov-2015

Ultrasensitive gas sensors based on the infusion of boron atoms into graphene -- a tightly bound matrix of carbon atoms -- may soon be possible, according to an international team of researchers from six countries. Graphene is known for its remarkable strength and ability to transport electrons ...

Terahertz dance of amino acids

RUB chemists explain the fingerprint of dissolved glycine in the Terahertz range

01-Apr-2014

Chemists at the Ruhr-Universität Bochum (RUB) have, for the first time, completely analysed the fingerprint region of the Terahertz spectrum of a biologically relevant molecule in water, in this case, an amino acid. By combining spectroscopy and molecular-dynamics simulations, they rendered the ...

High-strengh materials from the pressure cooker

A surprise in materials chemistry: At Vienna University of Technology, materials for lightweight construction, protective clothing or sports equipment can be produced at high temperatures and high pressures.

19-Mar-2014

The earth’s crust works like a pressure cooker. Minerals typically do not form under standard conditions, but at high temperatures and pressures. However, an environment of extreme heat and pressure has been considered to be absolutely unsuitable for organic molecules. Scientists at Vienna ...

New: An environmentally friendly chemical reaction that does not waste any atoms

06-Mar-2014

In the Research Group of Nuno Maulide, a chemist working at the University of Vienna, a new chemical synthesis forα-arylated Carbonyl derivatives was developed. Members of this class of substances typically possess interesting biological and pharmacological properties and often find applications ...
