• American biochemist to receive this year's Inhoffen Medal
  

  How do bacteria cope when exposed to toxic mercury, how are they able to outlast antibiotics, and how can they be killed using so-called "suicide inhibitors?" These are but a few of the many research topics US biochemist Christopher Walsh has devoted his career as a scientist to. Walsh will be honou more

• Light tsunami in a superconductor
  

  In their latest experiment, Prof. Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter at the Hamburg-based Center for Free-Electron Laser Science (CFEL) and Dr. Michael Gensch from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) investigated together with other co more

• Titanium dioxide nanoreactor
  

  Now, Dr. Katja Henzler and a team of chemists at the Helmholtz Centre Berlin have developed a synthesis to produce nanoparticles at room temperature in a polymer network. Their analysis, conducted at BESSY II, Berlin's synchrotron radiation source, has revealed the crystalline structure of the nanop more

• Macro- versus Microscopic View on the Electrokinetics of a Water–Membrane Interface

  Electrophoresis is an experimental method widely used to study electrostatic properties of interfaces. Here, we question the validity of the macroscopic theory for the planar geometry by Helmholtz and Smoluchowski by considering a POPC bilayer in an aqueous solution with 500 mM NaCl, using molecular more

• Bubble-Point Measurements of Eight Binary Mixtures for Organic Rankine Cycle Applications

  The bubble-point pressures of two compositions of each of eight binary mixtures have been measured over a temperature range of 270 K to 380 K. Six of the mixtures included pentane, which was mixed with 1,1,1,3,3-pentafluoropropane (R-245fa); methyl perfluoropropyl ether (R-E347mcc); 1,1,1,2,2,4,5,5, more

• Sum Frequency Generation Spectroscopy of Imidazolium-Based Ionic Liquids with Cyano-Functionalized Anions at the Solid Salt–Liquid Interface

  A surface-sensitive nonlinear vibrational spectroscopic technique, sum frequency generation (SFG), has been used to study cyano-containing ionic liquids in contact with two different solid salt surfaces. Specifically, the interfacial chemistry of BaF2(111) single-crystal and solid NaCl{100} surfaces more
