Global market for nanotechnology incorporated in manufactured goods will worth US$ 1.6 Trillion in 2013
In coming years, products based on nanotechnology will have a huge impact on nearly all-industrial sectors and will enter the consumer market in large quantities. Considering the future prospects of nanotechnology, countries across the world are investing heavily in this sector to reap maximum benefits from it… read more
The world’s smallest superconductor
Superconducting materials have an electrical resistance of zero, and so can carry large electrical currents without power dissipation or heat generation. Superconductivity was first discovered in 1911, and until recently, was considered a macroscopic phenomenon. The current finding suggests, however, that it exists at the molecular scale, which opens up a novel route for studying this phenomenon… read more
Lab-on-a-chip: “Virtual Electrowetting Channels”
Microfluidic devices typically depend upon electrokinetic or traditional pressure methods to move microscopic amounts of fluid around a fixed microchip. UC engineering researchers create tiny pools without walls with programmable microfluidic systems… read more
Gold nanoparticles help researchers detect melamine in milk
Melamine is the compound found in contaminated pet food and in tainted dairy products from China in 2007 and 2008 respectively. The laced dairy products were responsible for sickening thousands of people, especially children. Monitoring melamine-tainted products continues to be a worldwide concern. This study develops a facile and accurate approach towards detection of melamine utilizing gold nanoparticles and a dual color and precipitation test. The complete detection methodology is completed in less than 15 minutes… read more
Carbon nanostructures – good or bad?
A Los Alamos National Laboratory toxicologist and a multidisciplinary team of researchers have documented potential cellular damage from “fullerenes”—soccer-ball-shaped, cage-like molecules composed of 60 carbon atoms. The team also noted that this particular type of damage might hold hope for treatment of Parkinson’s disease, Alzheimer’s disease, or even cancer… read more
