ChemPhysChem 10/2014: Special issue on electrochemical energy conversion and storage
Issue 10 is a special issue on electrochemical energy conversion and storage. It has been guest edited by H. Baltruschat, K. Rajeshwar, and Y.-K. Sun and includes 27 invited contributions in this interesting field. In a Review, N. Dupré and colleagues study the interphase evolution at two promising electrode materials for Li-ion batteries. The Minireview by L. M. Peter and K. G. Upul Wijayantha summarizes the fundamental problems and new perspectives of photoelectrochemical water splitting at semiconductor electrodes. In the Articles section, W. Schmickler et al. combine DFT and molecular dynamics to study the electrochemical adsorption of OH on Pt in alkaline solutions while S. Komaba and co-workers report on a new enzyme-based anode for biofuel cells. Finally, in the Communications section, J. M. Feliu et al. describe the synthesis and electrocatalytic properties of Pt nanoparticles prepared in a water-in-oil microemulsion.

A series of functionalized porphyrin molecules containing electron-rich alkynes, synthesized by means of the Sonogashira coupling reaction, are further modified by reacting the ethynyl groups with click reagents through a formal [2+2] click reaction. Through a phase-exchange self-assembly method, highly organized morphologies are observed by scanning electron microscopy.

Ground control to Major Tom: Global control over the self-assembly of tetraundecyl metal porphyrins into a monolayer at a solid/liquid interface is governed by the concentration and composition of the supernatant solution. Subsequent manipulation by nanoshaving with a scanning tunneling microscopy tip creates monolayer defects, which can mediate a decrease or increase in local surface density, or the insertion of a second species of the same shape.
- Dioxetane Scission Products Unchanged by Mechanical Force

Illuminating mechanoluminescence: Dioxetane-based force-induced light emission from polymers is a powerful new way to characterize polymer behavior under stress. Here we reveal that the dioxetane is broken mechanically into products almost identical to those formed by heating at elevated temperatures (see figure). Excited- and ground-state degeneracy is thought to play a critical role in regulating the outcome of the mechanical scission process.
- Determination of Solubility Parameters of Ionic Liquids and Ionic Liquid/Solvent Mixtures from Intrinsic Viscosity

Viewing the Mix in 3D: The solvation power of ionic liquids and ionic liquid/solvent mixtures was studied by using an intrinsic viscosity method that allowed the determination of Hildebrand and Hansen solubility parameters, in particular, dispersion, polar and hydrogen-bonding solubility parameters. These partial solubility parameters can be visualized as coordinates in a 3D diagram, allowing illustration of the miscibility of different materials.
