Biomolekulare Computer, die aus DNS und anderen biologischen Molekuelen bestehen, existieren heute nur in einigen wenigen Speziallabors. Wissenschaftler am Weizmann Institut haben einen Weg gefunden, 'benutzerfreundliche' mikroskopische Computer zu entwickeln, die komplexe Berechnungen und komplizierte Datenabfragen durchfuehren koennen.
One of the long standing problems in the drinks industry is how to prevent chemical processes in the drinks compromising their taste, quality and shelf life. In particular, riboflavin (vitamin B2) is responsible for driving photooxidation reactions that affect the flavour of many drinks and so they often have to be packaged in light-shielded containers. Scientists now have developed a way of removing riboflavin.
The ultimate reference book, providing an in-depth introduction to nanotechnology, discussing topics from ethics and philosophy to challenges faced by this up-and-coming industry, all in one comprehensive volume.
Conquering one of the biggest challenges in the study of high-temperature superconductors, scientists at Brookhaven National Laboratory have grown crystals of one such material that are large enough to directly measure the material?s magnetic properties.
Thirty students from the Albany, Schenectady and Troy City School Districts participated in a tree-planting ceremony at the College of Nanoscale Science and Engineering of the University at Albany on July 31 to mark the completion of the first-ever Institute of Nanoscale Technology and Youth Summer Workshop.
Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building or the profile of the eastern seaboard.
Researchers in Sweden are breaking boundaries in the field of nerve cell communication by creating the first artificial nerve cell capable of communicating with human nerve cells. The research will fuel understanding in the pathophysiology, molecular targets and therapies for the treatment of various nervous system disorders such as Parkinson's disease.
The project will produce gallium arsenide-based solar batteries for satellites and space stations, with battery efficiency increased from 15 to 32% compared to silicon-based batteries. The new batteries are made up of three-junction solar cells consisting of up to 30 interleaving layers, each measuring 10-15 nm in thickness.
Graphane has the same honeycomb structure as graphene, except that it is 'spray-painted' with hydrogen atoms that attach themselves to the carbon. The resulting bonds between the hydrogen and carbon atoms effectively tie down the electrons that make graphene so conducting.
Neue Werkstoffe fuer die elektrochemische Energiespeicherung und Energiewandlung stehen im Fokus des Materialwissenschaftlichen Zentrums (MWZ), das am Karlsruher Institut fuer Technologie entstehen wird.
Engineers have developed a new method for creating high-performance membranes from crystal sieves called zeolites; the method could increase the energy efficiency of chemical separations up to 50 times over conventional methods and enable higher production rates.
