Not just cars, but living organisms need antifreeze to survive

20-Feb-2013 - If you thought antifreeze was only something that was necessary to keep your car from freezing up in the winter, think again. Plants and animals living in cold climates have natural antifreeze proteins (AFPs) which prevent ice growth and crystallization of organic fluid matter. Without such ...

Physicists capture first images of atomic spin

03-May-2010 - Though scientists argue that the emerging technology of spintronics may trump conventional electronics for building the next generation of faster, smaller, more efficient computers and high-tech devices, no one has actually seen the spin—a quantum mechanical property of electrons—in individual ...

Scientists discover world's smallest superconductor

Study paves way for development of nanocircuits for energy, electronics applications

07-Apr-2010 - Scientists have discovered the world's smallest superconductor, a sheet of four pairs of molecules less than one nanometer wide. The Ohio University-led study, published in Nature Nanotechnology, provides the first evidence that nanoscale molecular superconducting wires can be fabricated, which ...

Catalyst releases hydrogen from the ultimate renewable source: urine

06-Jul-2009 - You do two things at motorway services: fill up one tank and empty another. US chemists have combined refuelling your car and relieving yourself by creating a new catalyst that can extract hydrogen from urine. Chemistry World reports that the catalyst could not only fuel the hydrogen-powered ...

Scientists discover new method of observing interactions in nanoscale systems

18-Jan-2008 - Scientists have used new optical technologies to observe interactions in nanoscale systems that Heisenberg's uncertainty principle usually would prohibit, according to a study published in Nature. Researchers conducted experiments with high-powered lasers and quantum dots - artificial atoms that ...
