| Electrical control of single atom magnets Posted: 08 Dec 2013 10:36 AM PST The energy needed to change the magnetic orientation of a single atom -- which determines its magnetic stability and therefore its usefulness in a variety of future device applications -- can be modified by varying the atom's electrical coupling to nearby metals.  |
| Scientists discover quick recipe for producing hydrogen Posted: 08 Dec 2013 10:36 AM PST Scientists have discovered a quick-cook recipe for copious volumes of hydrogen, a breakthrough suggesting a better way of producing the fuel that propels rockets and energizes battery-like fuel cells. It could eventually even help meet key world energy needs -- without carbon emissions contributing to climate change.  |
| Possibility of cloning quantum information from the past Posted: 08 Dec 2013 06:06 AM PST Popular television shows such as "Doctor Who" have brought the idea of time travel into the vernacular of popular culture. But problem of time travel is even more complicated than one might think. Scientists have now shown that it would theoretically be possible for time travelers to copy quantum data from the past.  |
| Tiny drops of hot quark soup -- how small can they be? Posted: 06 Dec 2013 01:30 PM PST New analyses of deuteron-gold collisions indicate that collisions between gold ions and much smaller deuterons, designed as control experiments, may be serving up miniscule drops of hot quark-gluon plasma.  |
| Quantum effects help cells capture light, but the details are obscure Posted: 06 Dec 2013 09:44 AM PST By studying the behavior of light-gathering molecules used by plants, algae, and some bacteria in photosynthesis, researchers have found evidence that quantum coherence eases ultrafast energy transfers among the molecules.  |
| Coal yields plenty of graphene quantum dots Posted: 06 Dec 2013 08:17 AM PST Coal is a cost-effective source of abundant graphene quantum dots for photovoltaic, medical, electronic and sensing applications.  |
| The heat is on...or off: Having the sense to cut office energy bills Posted: 06 Dec 2013 07:16 AM PST Office buildings have an enormous carbon footprint, but often energy is being wasted maintaining empty rooms and spaces at a comfortable temperature. New research shows how the ubiquity of smart phones connected to the office network could be used to monitor occupancy and reduce heating or air conditioning for unused spaces.  |
| Tougher dies for automotive manufacturing Posted: 06 Dec 2013 06:14 AM PST Forming dies are put under immense strain. Yet by using a laser to alloy their surfaces with filler material you can make them more robust and resistant to wear. This process increases the service life of dies used in automotive manufacturing by 150 percent.  |
