Wissenschaftler der Uni Hamburg konnten erstmals ein funktionierendes Spintronik-Logik-Bauteil verwirklichen, das aus wenigen magnetischen Atomen aufgebaut ist. Beim Schalten des realisierten logischen Oder-Gatters ist im Gegensatz zu herkoemmlichen elektronischen Bauteilen kein Stromfluss noetig, da nur die magnetische Ausrichtung der Atome umgeschaltet wird.
Flash forward 20 years... What if our best efforts to lower carbon emissions, wean off fossil fuels, and plan for a soaring population weren't enough? Would we ask ourselves why we didn't take action sooner, transforming the ideas from our greatest innovators into the technologies needed to prepare for a more secure and sustainable future?
Adding a few graphene layers onto the conventional gold-film surface plasmon resonance (SPR) biosensor will boost up its sensitivity dramatically. The improved sensitivity comes from the graphene layer's increased adsorption of biomolecules and the graphene layer's optical modification to the SPR.
Researchers from the Vienna Center for Quantum Science and Technology at the University of Vienna and the Institute of Quantum Optics and Quantum Information at the Austrian Academy of Sciences used a quantum mechanical system in the laboratory to simulate complex many-body systems.
Researchers in the Materials Science and Technology division of the Naval Research Laboratory have recently demonstrated electrical injection, detection and precession of spin accumulation in silicon, the cornerstone material of modern device technology, at temperatures up to 225 degrees Celsius.
A world-first cattle vaccine based on nanotechnology could provide protection from the Bovine Viral Diarrhoea Virus (BVDV), which costs the Australian cattle industry tens of millions of dollars in lost revenue each year.
Intel Corporation today announced a significant breakthrough in the evolution of the transistor, the microscopic building block of modern electronics. For the first time since the invention of silicon transistors over 50 years ago, transistors using a three-dimensional structure will be put into high-volume manufacturing.
The Nanoinformatics 2020 Roadmap is the first broad-based nanotech community effort to attempt to comprehensively meet the needs and goals of nanoinformatics, which is the intersection of nanotechnology, computer science and data management.
In a new study, UCLA scientists report that by using engineered mesoporous silica nanoparticles as delivery vehicles, they were able to achieve significant increases in the percentage of drug-carrying nanoparticles that reach and are retained at tumor sites.
The Center of Innovation for Nanobiotechnology (COIN) today announced the upcoming NanoBio Executive Roundtable event to be hosted at RTP Foundation in Durham, NC on May 17, 2011. This Roundtable will tackle regulatory issues surrounding nanomedicine commercialization.
