When an atom collides with a molecule, traditional wisdom said the atom had to strike one end of the molecule hard to deliver energy to it. Researchers now found that a speeding hydrogen atom does not have to score a direct hit on a deuterium molecule, a form of molecular hydrogen made up of two heavy isotopes of hydrogen, to set the molecule vibrating.
The engineers unveiled a method for making integrated circuit chips with complex nanotube components on the scale and with the parallelism that the semiconductor industry must employ to make chips that are economical.
The Research Explorer is a comprehensive source of information on all types of research institutions in Germany, presented in a systematic and compact form, and available to users worldwide free of charge.
The integration of biosensors in wound dressing materials or other medical textiles opens up new and cost-effective perspectives in patient care. In a European project directed by the CSEM, intensive research is being conducted in this area. The sixth NanoEurope, which will be held in St.Gallen (Switzerland) on September 16 and 17, 2008, will present this application and other innovations from the field of nanotechnology to the interested specialist public.
Scientists discovered a new physical phenomenon that enables them to see high frequency waves by combining molecular dynamics simulations of shock waves with an experimental diagnostic, terahertz (THz) radiation.
The state-of-the-art technique for seeing atoms - transmission electron microscopy (TEM) - will become an important tool for chemical analysis over the next decade as instrument manufacturers commercialise advances pioneered in laboratories, researchers heard at the Microscience 2008 conference in London, UK.
Through the EU-backed, three-year NEMSIC (Nano-electro-mechanical-system-integrated-circuits) project, scientists aim to get the world's smallest, high-performance and low-power sensor in silicon off the ground.
A dynamic way to alter the shape and size of microscopic three-dimensional structures built out of proteins has been developed by biological chemist Jason Shear and his former graduate student Bryan Kaehr at The University of Texas at Austin.
