Like Fish on Waves: Electrons Go Surfing

Published: September 22, 2011.
By Ruhr-University Bochum
http://www.ruhr-uni-bochum.de

Physicists at the RUB, working in collaboration with researchers from Grenoble and Tokyo, have succeeded in taking a decisive step towards the development of more powerful computers. They were able to define two little quantum dots (QDs), occupied with electrons, in a semiconductor and to select a single electron from one of them using a sound wave, and then to transport it to the neighbouring QD. A single electron "surfs" thus from one quantum dot to the next like a fish on a…

A Semi-artificial Leaf Faster Than 'Natural' Photosynthesis
In leaves, photosystem 1 (PS1) absorbs light and its energy is finally utilized for the conversion of carbon dioxide to biomass. Photovoltaic devices, mostly build from silicon based semiconductors, also harness solar light but produce electricity. One approach for the development of cheaper and renewable photovoltaics consists in replacing the semi-conductor with the isolated membrane protein complexes of photosynthesis. Prof. Dr. Matthias Rögner's team isolates a highly stable PS1 from thermophilic cyanobacteria that live in a hot spring in Japan. However, the integration…

A Protecting Umbrella Against Oxygen
In a paper published this week in the journal Nature Chemistry, researchers from the Center for Electrochemical Sciences – CES at the Ruhr-University Bochum and from the Max-Planck-Institute for Chemical Energy Conversion in Mülheim an der Ruhr report a novel concept to work with efficient and possibly cheaper catalysts. A kind of buffer protects the catalysts against the hostile conditions encountered in fuel cells, which have been to date dismissed utilization. The scientists report in the current issue of Nature Chemistry. …

Preterm Children Do Not Have an Increased Risk for Dyscalculia
Preterm children do not suffer from dyscalculia more often than healthy full term children. Dr Julia Jäkel, a developmental psychologist from Bochum, and her colleague Prof Dr Dieter Wolke from the University of Warwick, UK proved this thesis to be true in their analyses – thus refuting previous scientific studies. Unlike other studies, the researchers took the children's IQ into consideration. Dyscalculia in preterm children often impossible to diagnose

RUB Chemists Develop Novel Catalyst with 2 Functions
Chemists at the Ruhr-Universität Bochum have made a decisive step towards more cost-efficient regenerative fuel cells and rechargeable metal-air batteries. They developed a new type of catalyst on the basis of carbon, which can facilitate two opposite reactions: electrolysis of water and combustion of hydrogen with oxygen. A catalyst of this kind might make the storage of wind and solar energy and the manufacture of cost-efficient batteries, for example for electric cars, possible. The team published their report in the "International Edition" of…

Sandalwood Scent Facilitates Wound Healing And Skin Regeneration
Skin cells possess an olfactory receptor for sandalwood scent, as researchers at the Ruhr-Universität Bochum have discovered. Their data indicate that the cell proliferation increases and wound healing improves if those receptors are activated. This mechanism constitutes a possible starting point for new drugs and cosmetics. The team headed by Dr Daniela Busse and Prof Dr Dr Dr med habil Hanns Hatt from the Department for Cellphysiology published their report in the "Journal of Investigative Dermatology". …
