Computers might one day recycle part of their own waste heat, using a material being studied by researchers at Ohio State University. The material is a semiconductor called gallium manganese arsenide. The researchers describe the detection of an effect that converts heat into a quantum mechanical phenomenon - known as spin - in a semiconductor.
Ultra-thin solar cells can absorb sunlight more efficiently than the thicker, more expensive-to-make silicon cells used today, because light behaves differently at scales around a nanometer (a billionth of a meter), say Stanford engineers. They calculate that by properly configuring the thicknesses of several thin layers of films, an organic polymer thin film could absorb as much as 10 times more energy from sunlight than was thought possible.
Getting an inside look at the center of a cell can be as easy as a needle prick, thanks to University of Illinois researchers who have developed a tiny needle to deliver a shot right to a cell's nucleus.
A team led by engineers and physicists at the University of New South Wales (UNSW) in Sydney, Australia, have developed one of the key building blocks needed to make a quantum computer using silicon: a 'single electron reader'.
Researchers from University of New South Wales (Australia), University of Melbourne (Australia), and Aalto University (Finland) have succeeded in demonstrating a high-fidelity detection scheme for the magnetic state of a single electron, that is, the spin.
The study aimed to review the basic principles, application and the potential health implications associated with the use of nanotechnology in the food sector, particularly on food and food contact materials incorporated with nanomaterials.
By constructing a microscope apparatus that achieves resolution never before possible in living cells, researchers at Albert Einstein College of Medicine of Yeshiva University have illuminated the molecular interactions that occur during one of the most important 'trips' in all of biology: the journey of individual messenger Ribonucleic acid (RNA) molecules from the nucleus into the cytoplasm (the area between the nucleus and cell membrane) so that proteins can be made.
In a major physics breakthrough with international significance, University of Otago scientists have developed a technique to consistently isolate and capture a fast-moving neutral atom - and have also seen and photographed this atom for the first time.
The International Academy of Science, Engineering and Technology (International ASET) and the University of Ottawa are pleased to organize the 2nd International Conference on Nanotechnology: Fundamentals and Applications. The conference will take place in Ottawa, Canada, 27-29 July 2011.
Using optically dense, ultra-cold clouds of rubidium atoms, researchers have made advances in three key elements needed for quantum information systems - including a technique for converting photons carrying quantum data to wavelengths that can be transmitted long distances on optical fiber telecom networks.
