Chemists monitor single-molecule switching in action

An international team under the leadership of chemists from Innsbruck succeeded in monitoring the S-adenosylmethionine (SAM) II-riboswitch in action. SAM is a cofactor which is involved in many metabolism processes by transferring methyl groups to other molecules.

Physicists create quantum twin atoms

Objects that are well separated in space but still cannot be understood separately belong to the profoundest mysteries of quantum physics. Pairs of photons are prominent examples of such systems. They allow the teleportation of quantum states or tap-proof data transfer using quantum cryptography. In future, such experiments will not be restricted simply to photons: at the Vienna University of Technology, a method has been developed to create correlated pairs of atoms using ultracold Bose-Einstein condensates.

Eco-friendly nanotechnology

Dr. Yuri Lvov, professor of chemistry and T.C. Pipes endowed chair in micro and nanosystems at Louisiana Tech University, recently led a symposium at the 241st Conference of the American Chemical Society (ACS), discussing his application of a more eco-friendly and cost-effective nano-material that can be used to significantly improve the properties of plastics, paints and other synthetic composites.
