Invisible for electrons

As thin as it gets: the carbon membranes recently created by Max Planck scientists are only one atom thick. For electrons, such membranes are almost completely transparent -- using an electron microscope, scientists may thus be able to examine absorbed individual molecules on the membranes, and image the atomic structure of complex biological molecules. Such ultra-thin membranes may also be used to filter out gases (Nature, March 1, 2007).

   07-16-2007 · EurekAlert!
   NRL scientists have efficiently injected a current of spin-polarized electrons from a ferromagnetic metal contact into silicon, producing a large electron spin polarization in the silicon. This demonstration is a key enabling step for developing devices which rely on electron spin rather than electron charge, a field known as semiconductor spintronics, and is expected to provide higher performance with lower power consumption and heat dissipation.

4. All alone, ammonia and hydrogen chloride use negativity to get attached
   02-14-2008 · EurekAlert!
   Electrons can spur the chemical reaction between an acid and a base, according to new results in Science, a finding that may help researchers precisely control reactions in areas from biology to energy technology. By isolating one molecule each of hydrogen chloride and ammonia, the researchers found that by adding or removing one extra electron to this skeletal environment, they could make the reaction go from acid and base to neutral molecule or back again.

   Research published online in the journal Science this week by Tonica Valla, a physicist at Brookhaven, appears to resolve one mystery in the 20-year study of high-temperature (high Tc) superconductors -- materials that lose their resistance to the flow of electricity at relatively high temperatures. The research shows that a "pseudogap" in the energy level of the material's electronic spectrum is the result of the electrons being bound into pairs above the so-called transition temperature to the
