Major advances in the field of organic electronics are currently revolutionising previously silicon-dominated semiconductor technology. Customised organic molecules enable the production of lightweight, mechanically flexible electronic components that are perfectly adapted to individual applications.
An interdisciplinary team headed by Charité – Universitätsmedizin Berlin scientists has examined the complicated structure of dentin in human teeth. Human teeth are designed to last a lifetime irrespective of the number of forces they are subjected to. However, the scientists have still not fully interpreted the high failure resistance of dentin. The scientists at the synchrotron sources BESSY II at HZB, Berlin, Germany, and the European Synchrotron Radiation Facility ESRF, Grenoble, France were able to report precompression of mineral particles. The resistance of the biostructure was increased as internal stress works against the advancement of cracks.
Today, with the theme “Nanotechnology for European competitiveness”, EuroNanoForum 2015 is bringing together major industry players, policymakers, leading academia representatives and most innovative SMEs from around the world to address key challenges of the economic growth and European re-industrialisation by embracing change.
Photoinduced chemical reactions are responsible for many fundamental processes and technologies, from energy conversion in nature to micro fabrication by photo-lithography. One process that is known from everyday’s life and can be observed by the naked eye, is the exposure of photographic film.
Researchers at the University of Illinois at Urbana-Champaign have reported physical mechanisms that use heat to manipulate magnetic information. Unlike the conventional methods that involve application of magnetic fields, these mechanisms are based on the transport of heat energy, providing a suitable way to control magnetization at nano-level.
Due to the weak electron-phonon coupling in graphene, 2D Dirac massless carriers can present a much more elevated temperature than the graphene lattice. Such hot carriers propagate over long distances resulting in novel thermoelectric and optoelectronic phenomena.
The nanoLED SEM image (pictured) by Eindhoven University of Technology (TU/e) recently won a competition held by Oxford Instruments Plasma Technology, and chosen from a large number of entries, all demonstrating unique and intriguing process results obtained using Oxford Instruments equipment.
Working with a device that slightly resembles a microscopically tiny tuning fork, researchers at the University of Tsukuba in Japan have recently developed coupled microcantilevers that can make mass measurements on the order of nanograms with only a 1 percent margin of error -- potentially enabling the weighing of individual molecules in liquid environments. The findings are published this week in Applied Physics Letters, from AIP Publishing.
Protea Biosciences Group, Inc. announced today a new, silicon chip technology that enables the rapid identification and quantitation of small molecules in biofluids. The announcement was made at the 63rd American Society of Mass Spectrometry (ASMS) Conference on Mass Spectrometry and Allied Topics, held in St. Louis, MO.
Imagine a fabric that will keep your body at a comfortable temperature--regardless of how hot or cold it actually is. That's the goal of an engineering project at the University of California, San Diego, funded with a $2.6M grant from the U.S. Department of Energy's Advanced Research Projects Agency - Energy (ARPA-E). Wearing this smart fabric could potentially reduce heating and air conditioning bills for buildings and homes.
