Mysterious catalyst explained: how gold nanoparticles aid the production of plastic components

May 1, 2013 – 3:35 am
  • Mysterious catalyst explained: how gold nanoparticles aid the production of plastic components - From methanol to formaldehyde - this reaction is the starting point for the synthesis of many everyday plastics. Using catalysts made of gold particles, formaldehyde could be produced without the environmentally hazardous waste generated in conventional methods. Just how the mysterious gold catalyst works has been found out by theoretical and experimental researchers at the Ruhr-Universität Bochum in a cooperation project.(10.1002/anie.201301868)

    Specialised germanium surface as universal protein adapter

    March 10, 2013 – 3:01 pm
  • Specialised germanium surface as universal protein adapter - Researchers at the Ruhr Universität Bochum have developed a new method for attaching proteins to the surface of germanium crystals -- for the first time also membrane proteins. This enables time-resolved tracking of the interactions between molecules using infrared spectroscopy in a way that is accurate down to atomic resolution. The method is applied in the EU project "Kinetics for Drug Discovery, K4DD," in which scientists explore the interplay of drugs and their interaction partners. With the new technology, the researchers can also study so-called G-protein-coupled receptors, which are the site of action for many drugs.(10.1021/ja400253p)

    Temporary storage for electrons in a hydrogen-producing enzyme

    November 4, 2012 – 10:02 pm

    Temporary storage for electrons in a hydrogen-producing enzyme - Scientists at the Max Planck Institute for Chemical Energy Conversion (MPI CEC) and the Ruhr-Universität Bochum (RUB) have found through spectroscopic investigations on a hydrogen-producing enzyme that the environment of the catalytic site acts as an electron reservoir in the enzyme. Thus, it can very efficiently produce hydrogen, which has great potential as a renewable energy source.(10.1002/anie.201204800)
