(Kureczka/Martin Associates) A nonabsorbed, oral co-polymer therapy under development by Midway Pharmaceuticals demonstrated the ability to protect against damage to healthy gastrointestinal tissues and to prevent lethal bacterial infections in animal models of radiation damage. The results suggest the compound, a high molecular weight co-polymer of polyethylene glycol (PEG), may provide a new way to prevent serious GI side effects of radiation in patients receiving fractionated radiotherapy for abdominal cancers or in accidental exposures to harmful radiation.

(Swiss Federal Laboratories for Materials Testing and Research (EMPA)) Two-dimensional carbon layers, so-called graphenes, are regarded as a possible substitute for silicon in the semiconductor industry. The electronic properties of these layers can be varied by “building in” specific arrays of holes in their structure. Physicists at Empa, together with chemists from the Max Planck Institute for Polymer Research in Mainz have, for the first time, succeeded in synthesizing a graphene-like porous polymer with atomic accuracy.

A way to toughen up the latex particles used to make emulsion paints has been developed by UK chemists. The approach involves adding tiny slivers of clay armor to make the particles more hard wearing and fire resistant.
Until now, latex emulsion paints have been made by adding a soap-like surfactant molecule to allow the hydrophobic, [...]
