• Water is an active element in proteins
  

  Biophysicists in Bochum have discovered a diode for protons: just like the electronic component determines the direction of flow of electric current, the “proton diode” ensures that protons can only pass through a cell membrane in one direction. Water molecules play an important role here as active more

• Watching electrons move in real time

  At its most basic level, understanding chemistry means understanding what electrons are doing. Research published in The Journal of Chemical Physics not only maps the movement of electrons in real time but also observes a concerted electron and proton transfer that is quite different from any previo more

• How to count the messenger out

  Water molecules are continuously forming short-lived networks called clusters. These can in turn bind positively charged protons, and such clusters can provide active functional groups in proteins. Using infrared spectroscopy, it is possible to determine the bond strengths, geometrical structures an more

• Stress acidulated amphoteric molecules and mechanochromism via reversible intermolecular proton transfer

  Stress has been proved to acidulate amphoteric molecules and promote an intermolecular proton transfer, which results in a significant absorption and emission change. The stress acidulated amphoteric molecules open a new avenue for developing mechanochromic materials and anticipate many broad applic more

• CLIP-HSQMBC: Easy measurement of small proton-carbon coupling constants in organic molecules

  A user-friendly 2D NMR approach denoted as CLIP-HSQMBC is proposed for the very easy, direct and accurate measurement of long-range proton-carbon coupling constants in organic molecules and natural products. The J value can be extracted directly from the analysis of resolved in-phase 1H multiplets t more

• Electrogenerated Polypyridyl Ruthenium Hydride and Ligand Activation for Water Reduction to Hydrogen and Acetone to iso-Propanol

  The complex [Ru(tpy)(bpy)(S)]2+ (tpy = 2,2':6',2''-terpyridine, bpy = 2,2'-bipyridine, S = solvent) is an electrocatalyst for water or proton reduction to hydrogen and for reduction of acetone to iso-propanol in CH3CN. Electrocatalysis is initiated by sequential 1e– reductions at the tpy and bpy lig more
