New filtering technology has environmental, industrial applications
(20 Nov 2008)
Materials engineers have created a new type of membrane that separates oil from water and, if perfected, might be used for environmental cleanup, water purification and industrial applications. The new technology would last longer than ......

'Enlightened' atoms stage nano-riot againsts uniformity
(19 Nov 2008)
Harnessing this behavior could lead to cooler computer chips, better bio-sensors
When atoms in a crystal are struck by laser light, their electrons, excited by the light, typically begin moving back and forth together in a regular pattern, resembling nanoscale soldiers marching in a lockstep formation. But according to a ......

Test identifies toxic platinum and palladium without time-consuming sample pretreatment
(18 Nov 2008)
Fluorogenic solution glows green within four hours when even minute traces of poisonous Pd(II) and Pt(IV) are present
The painstaking process of detecting toxic species of platinum and palladium mixed in with the form of platinum essential to certain pharmaceuticals could be reduced to one simple step, University of Pittsburgh researchers report in the ......

Putting a new spin on current research
(18 Nov 2008)
Physicists in the USA and at the London Centre for Nanotechnology have found a way to extend the quantum lifetime of electrons by more than 5,000 per cent, as reported in Physical Review Letters. Electrons exhibit a property called 'spin' and ......

Brushing up on sensors
(14 Nov 2008)
Jason Locklin and his colleagues from the University of Georgia have developed covalently bound polymer brushes that can bind metal ions when irradiated with UV light. The polymer brushes, containing spiropyran moieties, were synthesised using ......

Improved spectrometer based on nonlinear optics
(14 Nov 2008)
New tool allows for higher sensitivity at reduced complexity and cost
Scientists at Stanford University and Japan's National Institute of Informatics have created a new highly sensitive infrared spectrometer. The device converts light from the infrared part of the spectrum to the visible part, where the ......

Mechanical calculations for methyl transfer in solution
(13 Nov 2008)
Ian Williams and colleagues at the University of Bath, UK, have demonstrated that kinetic isotope effects (KIEs) for a prototypical SN2 methyl transfer in solution, and in an enzyme active site, show significant variations in magnitude owing ......

UK fingerprint "developer” can read a letter from its envelope
(12 Nov 2008)
UK scientists have discovered a fingerprint "developer” which can highlight invisible prints on almost any surface – and read the text of a letter just from the envelope it was sent in. Paul Kelly and colleagues at Loughborough University found ......

New small-scale generator produces alternating current by stretching zinc oxide wires
(11 Nov 2008)
Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a flexible plastic substrate with two ends ......

Making cars and airplanes cheaper, safer and more efficient
(11 Nov 2008)
DFG funds 2 major instruments to test components made of fiber-reinforced composites
Two novel testing facilities for materials research will be provided to the Technical University of Braunschweig and Hamburg University of Technology by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation). For the first time ......
