In order to celebrate the great achievements accomplished by the late Dr. Heinrich Rohrer, Nobel Laureate and IBM Fellow and to further promote progress in research and development in the field of nanoscience and nanotechnology, an international prize was named after him in 2013 by The Surface Science Society of Japan (SSSJ) in collaboration with IBM Research Zurich, the Swiss Embassy in Japan and his wife Rose-Marie.
Modern hard drives only require an area of a few square nanometers for each bit of information. To protect ourselves from sunburn we use sunscreens that contain nanoparticles of titanium dioxide or zinc oxide. Is this the beginning of the nano era? Younan Xia from Georgia Institute of Technology pursues this question in his editorial.
The study results show that TriSilanol POSS, created by silanol bonds at the corners of the POSS molecule, increased both the strength and toughness of A4047 and A359 aluminum alloys. In the A359 sample where POSS was added, elongation to failure increased from 23% to 250% over the control sample. According to the authors, these results hold great promise for the automotive industry.
In Dimensionen vordringen, die nie ein Physiker zuvor gesehen hat: Auf diesem Weg befindet sich Professor Bert Hecht. Die Deutsche Forschungsgemeinschaft flankiert seinen Vorstoss mit 1,5 Millionen Euro.
Researchers have developed a coating technique that they plan to use to protect tur- bine engine and waste incinerator components against heat and oxidation. A topcoat from micro-scaled hollow aluminium oxide spheres provides heat insulation, in the lab, already proved more economical than conventional techniques.
Researchers at Sandia National Laboratories have received a $1.2 million award to develop a technique that they believe will significantly improve the efficiencies of photovoltaic materials and help make solar electricity cost-competitive with other sources of energy.
Researchers report on the in-situ self-assembly of vine-tree-like nanostructure using carbon nanotubes as the building blocks by chemical vapor deposition. This work also provides a general biomimetic strategy toward the design of hierarchical nanomaterials with extraordinary electron pathways as well as tunable surface/interface that can be used in areas of catalysis, separation, and energy conversion and storage.
Wissenschaftler haben eine neue Ansteuerung für Rastertunnelmikroskope entwickelt, die es ihnen ermöglicht, einzelne grosse Molekuele interaktiv mit der Hand zu verschieben. Bisher waren nur simple, starr programmierte Bewegungen moeglich.
Usually, light waves do not interact with each other. Coupling of photons with other photons is only possible with the help of special materials and very intense light. Scientists in Vienna have now created the strongest possible coupling of only two photons - an important achievement for quantum optics.
