Size matters — even for molecules

(PhysOrg.com) -- Two electrons that are emitted from a large molecule by a single photon may originate from far apart within that molecule. In a recent study on hydrocarbon molecules consisting of one to five fused benzene rings (each ring consisting of six carbon atoms), Synchrotron Radiation Center researchers Tim Hartman and Ralf Wehlitz have found that the relative probability for ejecting two electrons scales linearly with the length of the molecule.

New "Sponge" Material Could Trap Power Plant Pollution

There is a new sponge that researchers hope could absorb greenhouse gases from power plants one day. In a recent study, scientists at Lehigh University created a new material that pulls carbon dioxide and methane selectively from a stream of other gases. In theory, the new spongy substance could sop up heat-trapping gases emitted from the burning of coal or natural gas

Physicists offer countermeasure to new quantum eavesdropping attack

(PhysOrg.com) -- As early communications systems using quantum cryptography become commercially available, physicists have been investigating new types of security attacks in an effort to defend against them. In a recent study, researchers have identified and demonstrated a new, highly effective way to eavesdrop on a quantum key distribution (QKD) system that involves blinding the receiver’s detector during the "dead time" of single-photon detectors.
