Laser beams can be made to form dark as well as bright intensity helices, or corkscrews of light. Researchers have now shown that forming dark helices can have considerable advantages over employing their commonly considered bright cousins.
A newly developed carbon nanotube material could help lower the cost of fuel cells, catalytic converters and similar energy-related technologies by delivering a substitute for expensive platinum catalysts.
A team of researchers from Harvard University have invented a way to keep any metal surface free of ice and frost. The treated surfaces quickly shed even tiny, incipient condensation droplets or frost simply through gravity. The technology prevents ice sheets from developing on surfaces - and any ice that does form, slides off effortlessly.
In the past 100 years, 11 Nobel Prizes have been awarded to nearly two dozen people for the discovery or theoretical explanation of such cold materials - superconductors and Bose-Einstein condensates, to name two - yet a unifying theory of these extreme behaviors has eluded theorists. Physicists have now discovered a commonality among these materials that can be used to predict or even design new materials that will exhibit such unusual behavior.
The Health Council of the Netherlands has published a draft report in which a committee of the council advices on the implementation of an exposure registry and a system of health monitoring when working with engineered nanoparticles.
Recent studies have shown that microporous membranes can facilitate migration of epidermal cells, enabling the development of a seal that resists movement of fluid and microorganisms and therefore improving the implant life. Researchers have now devised a simple but innovative approach that combines both of these aspects simply by coating silicon nitride microporous membranes with a conformal coating of ultrathin ultrananocrystalline diamond films.
Das Institut für Laserphysik der Universität Hamburg hat gemeinsam mit vier Universitäten in Grossbritannien, Frankreich und Griechenland eine europäische Graduiertenschule zum Thema Quantensensoren eingeworben.
The collaboration agreement sets the framework for future collaboration projects between imec and Tohoku University where students, research staff, and professors will be exchanged between both organizations.
An international team of scientists, funded in the UK by the Biotechnology and Biological Sciences Research Council (BBSRC), has uncovered the structure of the protective protein coat which surrounds many bacteria like a miniature suit of armour.
A group of Swiss researchers from UNIGE, HUG and the University of Basel have developed a veritable 'time bomb,' a treatment for atherosclerosis that can recognize the diseased areas and treat only them.
Enabling bioengineers to design new molecular machines for nanotechnology applications is one of the possible outcomes of a study by University of Montreal researchers that was published in Nature Structural and Molecular Biology today.
