Read moreWorld's smallest semiconductor laser heralds new era in optical science
This breakthrough, described in an advanced online publication of the journal Nature on Sunday, Aug. 30, breaks new ground in the field of optics. The UC Berkeley team not only successfully squeezed l...
Physics and Astronomy | Read moreUCR scientists manipulate ripples in graphene, enabling strain-based graphene electronics
Graphene is nature's thinnest elastic material and displays exceptional mechanical and electronic properties. Its one-atom thickness, planar geometry, high current-carrying capacity and thermal c...

Materials Sciences | Read moreNew method could lead to narrower chip patterns
Such materials are not new, but the researchers found a novel way of harnessing that property to create a mask with exceptionally fine lines of transparency. This mask can then be used to create a cor...

Nanotubes, the tiny honeycomb cylinders of carbon atoms only a few nanometers wide, are perhaps the signature material of modern engineering research, but actually trying to organize the atomic scale ...
Physics and Astronomy | Read moreInfrared light visualizes nanoscale strain fields
The method, which is based on near-field microscopy, opens new avenues for analyzing mechanical properties of high-performance materials or for contact-free mapping of local conductivity in strain-eng...
Materials Sciences | Read moreNew Hybrid Nanostructures Detect Nanoscale Magnetism
A key challenge of nanotechnology research is investigating how different materials behave at lengths of merely one-billionth of a meter. When shrunk to such tiny sizes, many everyday materials exhibi...
Physics and Astronomy | Read more'Point of care diagnostics' in the starting blocks
Lab-on-a-chip systems bring the laboratory to the patient instead of the other way around: a blood sample will no longer have to go to the laboratory and the patient will no longer have to wait for th...
Health and Medicine | Read moreNew metamaterials that bend light backwards bring invisibility cloaks 1 step closer
Two breakthroughs in the development of metamaterials - composite materials with extraordinary capabilities to bend electromagnetic waves - are reported separately this week in the Aug. 13 advanced on...
Materials Sciences | Read more“Nanosculpture” Could Enable New Types of Heat Pumps and Energy Converters
A new technique for growing single-crystal nanorods and controlling their shape using biomolecules could enable the development of smaller, more powerful heat pumps and devices that harvest electricit...
Power and Electrical Engineering | Read moreNew technique to optimize computer speed
Until now, this strain remained difficult to observe. Now, thanks to a new electron holography technique (1) invented by researchers at the Centre d’élaboration de matériaux et d’études structurales (...

Three student teams will participate in a public exhibition at the 2008 U.S. “RoboCup Open” in Pittsburgh, Pa., May 25 to 27, where miniature “soccer players”—computer-driven robots six times smaller ...
Event News | Read moreNPL extends strategic relationship with the Advanced Technology Institute, Surrey for a further three years
This will further extend the contract signed in 2005, which included the appointment of a visiting NPL Strategic Research Fellow to work jointly between Surrey and NPL. The work undertaken under an um...
Physics and Astronomy | Read morePhysicists discover gold can be magnetic on the nanoscale
In another paper, they relate their discovery that gold in this size regime can be made magnetic through oxygenation of gold nanowires. They also found that up to a certain length, oxygenated gold na...
