Short Laser Pulses for Material Deposition with Cold Spray Technology

17-Apr-2015

In a new EU-funded project, ultra-short laser pulses modify material surfaces so that metal powder from a cold gas jet can adhere more easily. With Cold Spray Technology, coating lightweight materials such as plastics or carbon fiber reinforced plastic (CFRP) becomes significantly simpler. The EU ...

Bury nuclear waste down a very deep hole, say UK scientists

Deep borehole disposal of high level nuclear waste

17-Apr-2015

Scientists at the University of Sheffield calculate that all of the UK's high level nuclear waste from spent fuel reprocessing could be disposed of in just six boreholes 5km deep, fitting within a site no larger than a football pitch.The concept - called deep borehole disposal - has been ...

Nanostructures: customized carbon

A new synthesis method produces novel nanostructures from carbon

17-Apr-2015

They are tiny and comprise spherical, sheet-like or fibrous particles. And they consist chiefly of the chemical element carbon. The talk here is about unusual carbon nanostructures that scientists at the Max Planck Institute of Colloids and Interfaces in Potsdam-Golm are now producing with a ...

New synthetic technology for medicines and fine chemicals

17-Apr-2015

A University of Tokyo research group has succeeded in synthesizing (R)- and (S)-rolipram, the active component of a medicine, in high yield with high selectivity by a catalyzed flow fine synthesis instead of the traditional batch method used in the production of 99% of medicines.Professor Shu ...

'Parachuting' boron on benzene rings

A bulky catalyst induces pinpoint targeting on benzene to create bioactive molecules

16-Apr-2015

Tuning the para position of benzene moieties is significant for creating biologically active compounds and optoelectronic materials. Yet, attaching a functional handle specifically at the para position of benzene has been challenging due to multiple reactive sites on the ring. Chemists at ITbM, ...

Fast charging cycles make batteries age more quickly

X-ray study images structural damage in lithium-ion batteries

16-Apr-2015

Charging lithium-ion batteries too quickly can permanently reduce the battery capacity. Portions of the energy storage structure are thereby destroyed and deactivated. These structural changes have been visualized for the first time by DESY researcher Dr. Ulrike Bösenberg along with her team at ...

Rapid transfer from lab to roll – continuous coating on the pilot scale

Saving R&D time while reliably bringing new material formulations into near-production coating processes in a cost-efficient way: A clear benefit offered by Fraunhofer Institute for Silicate Research

16-Apr-2015

Saving R&D time while reliably bringing new material formulations into near-production coating processes in a cost-efficient way: A clear benefit offered by Fraunhofer Institute for Silicate Research ISC with a novel coating plant especially designed for easy up-scaling. Functional coatings are ...

Graphene looking promising for future spintronic devices

14-Apr-2015

Researchers at Chalmers University of Technology have discovered that large area graphene is able to preserve electron spin over an extended period, and communicate it over greater distances than had previously been known. This has opened the door for the development of spintronics, with an aim ...
