ChemPhysChem 8/2013: Converting methanol
K. Hemelsoet and and V. Van Speybroeck et al. unravel in their review the reaction mechanisms governing methanol-to-olefins catalysis by theory and experiment. A pedagogical perspective on ambipolar FETs is given in the concept written by M. S. Kang and C. D. Frisbie. In an article by D. Catone et al it is shown how temperature-dependent photoelectron circular dichroism can be used to analyze conformational and structural changes of unoriented chiral molecules, as exemplified by 3-methylcyclopentanone. And A. Vinu and co-workers present in their communication the enhanced supercapacitor performance of N-doped mesoporous carbons prepared from a gelatin poymer.

- Harnessing Light with Photonic Nanowires: Fundamentals and Applications to Quantum Optics
Dr. Julien Claudon, Dr. Niels Gregersen, Dr. Philippe Lalanne and Prof. Jean-Michel Gérard
Article first published online: 19 JUN 2013 | DOI: 10.1002/cphc.201300033

Fire the photons: Photonic nanowire antennas efficiently funnel the emission of an embedded quantum light source into a directive optical beam. In this Minireview, the physics and realization of such devices are discussed. The authors consider both bottom-up and top-down fabrication routes and review potential applications to solid-state quantum optics and beyond.
- Characterization of Thermally Stable Brønsted Acid Sites on Alumina-Supported Niobium Oxide after Calcination at High Temperatures
Tomoyuki Kitano, Dr. Tetsuya Shishido, Dr. Kentaro Teramura and Prof. Dr. Tsunehiro Tanaka
Article first published online: 19 JUN 2013 | DOI: 10.1002/cphc.201300189

Taking the heat: Thermally stable Brønsted acid sites are generated on Nb2O5/Al2O3 after calcination at high temperatures. Spectroscopic analysis shows that niobium oxide is supported as a monolayer domain and that the domains increase with increased loading up to 16 wt %. The Brønsted acid sites are generated at the boundaries of the niobium-oxide monolayer domains.
- Lithium-Functionalized Metal–Organic Frameworks that Show >10 wt % H2 Uptake at Ambient Temperature
Dr. Sang Soo Han, Dr. Dong Hyun Jung, Dr. Seung-Hoon Choi and Prof. Jiyoung Heo
Article first published online: 19 JUN 2013 | DOI: 10.1002/cphc.201300225

Grand designs: Grand canonical Monte Carlo simulations with a first-principles-based force field show that metal–organic frameworks (MOFs) with Li functional groups (i.e. C
Li bonds) offer exceptional H2 uptake at ambient temperature (see picture). For example, at 298 K and 100 bar, IRMOF-1-4Li shows a total H2 uptake of 5.54 wt % and MOF-200-27Li exhibits a total H2 uptake of 10.30 wt %, much higher than the corresponding values with pristine MOFs. - Study on Nanobubble Generation: Saline Solution/Water Exchange Method
Minghuan Liu, Wanchen Zhao, Shuo Wang, Wen Guo, Yuzhao Tang and Yaming Dong
Article first published online: 18 JUN 2013 | DOI: 10.1002/cphc.201201032

Repeatable nanobubble generation on a highly ordered pyrolytic graphite surface can be achieved by replacing water with saline solution or saline solution with water (see picture). Interestingly, nanobubbles are also observed by atomic force microscopy when saline liquids of different concentrations and valences are employed.
- The Registry Index: A Quantitative Measure of Materials′ Interfacial Commensurability
Dr. Oded Hod
Article first published online: 18 JUN 2013 | DOI: 10.1002/cphc.201300259

Simply sliding: The study of nanoscale tribology offers great potential in the fields of friction, wear, and lubrication. By considering a variety of hexagonal layered materials, including graphene, hexagonal boron nitride, and molybdenum disulfide, it is shown how a simple geometrical parameter, named the “registry index”, can capture the interlayer sliding energy landscape (see picture) as calculated by using advanced electronic structure methods as well as experimentally measured frictional behavior.
