Scientists produce best image yet of atoms moving in real time

April 18, 2013 – 11:01 am
  • Scientists produce best image yet of atoms moving in real time - Scientists have recorded atomic motions in real time, offering a glimpse into the very essence of chemistry and biology at the atomic level. Their recording is a direct observation of a transition state in which atoms undergo chemical transformation into new structures with new properties -- in this case the transfer of charge leading to metallic behavior in organic molecules.(10.1038/nature12044)

    Catalyst for green chemistry: Amberlyst-15 can act as a catalyst for the acylation of phenols and alcohols

    April 6, 2013 – 11:01 am
  • Catalyst for green chemistry: Amberlyst-15 can act as a catalyst for the acylation of phenols and alcohols - Researchers offer a novel and highly sustainable method for the acylation of phenols and alcohols. They found that Amberlyst-15 is an active catalyst for the acylation of phenols and alcohols by means of acetic anhydride as an acylating agent at room temperature under heterogeneous conditions. The scientists confirmed that applications of this catalyst allow mild and highly selective transformations and synthesis in a facile and environmentally friendly manner.(10.2478/recat-2012-0002)
