Helmut Schwarz and Edward Valeev win 2015 WATOC Awards
The World Association of Theoretical and Computational Chemists (WATOC) has awarded the 2015 Schrödinger Medal to Helmut Schwarz of the Technical University of Berlin (TU Berlin, Germany) and the 2015 Dirac Medal to Edward Valeev of Virginia Tech (USA). The awards will be presented to the two scientists at the next triennial WATOC congress, which will take place in Munich, Germany, in August 2017.

- Single-Molecule Methods to Study Membrane Receptor Oligomerization
Franziska Fricke, Marina S. Dietz and Prof. Dr. Mike Heilemann
Article first published online: 17 DEC 2014 | DOI: 10.1002/cphc.201402765
Singles′ party: Single-molecule techniques suitable for studying the oligomerization of membrane receptors are reviewed: photobleaching, Förster resonance energy transfer, localization microscopy and co-tracking. Experimental requirements, benefits and difficulties are discussed and biological applications are highlighted.
- Experimental Charge Density Evidence for Pnicogen Bonding in a Crystal of Ammonium Chloride
Dr. Yulia V. Nelyubina, Prof. Alexander A. Korlyukov and Prof. Konstantin A. Lyssenko

The ties that bind: Chemical binding in crystalline ammonium chloride was studied by using a topological analysis of electron density function derived from high-resolution X-ray diffraction. Supported by periodic quantum chemical calculations, it provided experimental evidence for weak σ-hole bonds (1.5 kcal mol−1) that involve ammonium cations in a crystal (see figure). This type of supramolecular interaction is even more numerous than now appears.
- Li[B(OCH2CF3)4]: Synthesis, Characterization and Electrochemical Application as a Conducting Salt for LiSB Batteries

Conducting salt for Li batteries? Li[B(OTfe)4] (OTfe=OCH2CF3) was synthesized as a water- and thermally stable lithium-ion electrolyte salt. The electrochemical stability in EC/DMC and in DME lies outside the limits of the solvents. As electrolyte salt, it exhibits good conductivities in many solutions. It was tested in LiS Batteries and shows good performance.
- Silver-Assisted Chemical Etching on Silicon with Polyvinylpyrrolidone-Mediated Formation of Silver Dendrites
Prof. Chia-Yun Chen and Po-Hsuan Hsiao
Article first published online: 17 DEC 2014 | DOI: 10.1002/cphc.201402634
The metal-assisted chemical etching (MaCE) of Si is systematically investigated. The morphology and crystallographic nature of silver dendrites grown by this method can be significantly modulated by the addition of polyvinylpyrrolidone (PVP).
- Enhanced Ferromagnetism in a Mn3C12N12H12 Sheet
Junyi Liu and Prof. Qiang Sun
Article first published online: 16 DEC 2014 | DOI: 10.1002/cphc.201402713
Attractive replacement: When sulfur atoms are replaced by NH groups in Mn3C12S12, the resulting Mn3C12N12H12 sheet exhibits strong ferromagnetism with a high Curie temperature (see figure). The enhanced ferromagnetism is due to the reduced lattice constant and nitrogen being more effective at mediating magnetic couplings through p–d exchange interactions.
