Metal oxides hold the key to cheap, green energy

Harnessing the energy of sunlight can be as simple as tuning the optical and electronic properties of metal oxides at the atomic level by making an artificial crystal or super-lattice 'sandwich' says a Binghamton University ...

Nano discs pose potential health risk

(PhysOrg.com) -- A revolutionary material that is used in computer technology could pose health risks to those involved in its manufacture.

Nanotechnology may lead to more energy-efficient electronics

Carbon nanotubes and graphene consist of just a couple of layers of carbon atoms, but they are lighter than aluminium, stronger than steel and can bend like spring-coils. Physicist Niklas Lindahl at the University of Gothenburg, ...

ORNL microscopy explores nanowires' weakest link

Individual atoms can make or break electronic properties in one of the world's smallest known conductors—quantum nanowires. Microscopic analysis at the Department of Energy's Oak Ridge National Laboratory is delivering ...

A quantum connection between light and motion

(PhysOrg.com) -- Physicists have demonstrated a system in which light is used to control the motion of an object that is large enough to be seen with the naked eye at the level where quantum mechanics governs its behavior.

Shaken, not heated: The ideal recipe for manipulating magnetism

(PhysOrg.com) -- Scientists have found a way to distort the atomic arrangement and change the magnetic properties of an important class of electronic materials with ultra-short pulses of terahertz (mid-infrared) laser light ...

Spotted under the microscope: How a virus puts on its armor

Scientists from VU University Amsterdam, Scripps Research Institute and the University of Michigan discovered how a virus 'puts on its armor'. This 'armor', consisting of mere proteins, is initially flexible and weak, but ...
