  • Breaking the bond: To take part or not?

    Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exc more

  • Filling lithium-ion cells faster

    Developers from Bosch and scientists at the Technical University of Munich (TUM) are using neutrons to analyze the filling of lithium ion batteries for hybrid cars with electrolytes. Their experiments show that electrodes are wetted twice as fast in a vacuum as under normal pressure. One of the most more

  • Stacking on the graphene

    Researchers in Japan have found a way to form two materials, each made of three layers of graphene. Each material's graphene is stacked differently and has unique electrical properties. Their work has implications for the development of novel electronic devices, such as photo sensors that convert li more

  • Particle sizing with static laser scattering

    When determining particle sizes a wide variety of techniques are used in which sieving may be the most popular. Sieving is a relatively simple technique, despite the fact that of course different instrumental approaches can be used. The main advantag more

  • Innovative Vacuum Regulation for Rotary Evaporators

    Different methods of vacuum regulation in rotary evaporators are compared according to their benefit for the user. Essential criteria of such analyses are process time, rate of solvent recovery, ease of handling, and flexibility. Speed controlled dia more

  • Battling Corrosion in Refineries

    Corrosion in refinery operations has been, and still is, the subject of many studies, papers, courses and web forums. Although a lot of what has been written shows that significant progress in understanding corrosion has been made, it also makes it more
