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.

Exciton–photon interactions: Coupling of ladder-type quarterphenyl to the photon modes of a dielectric ZrOx/SiOx microcavity at ultraviolet wavelengths is investigated. Single-mode lasing with a threshold of 0.4 mJ cm−2 in the weak-coupling regime and strong coupling with pronounced anti-crossing features at the (0,0) and (0,1) vibronic transitions of the molecule are observed.

Looking inside the barrel: Theoretical work aimed at understanding the absorption lineshape of the green fluorescent protein (GFP) chromophore in solution is presented. The spectra in various solvents of two analogues as mimics of the GFP chromophore are modeled using different approaches and compared to experimental data.
- Assessment of Luminescent Downshifting Layers for the Improvement of Light-Harvesting Efficiency in Dye-Sensitized Solar Cells
Zahra Hosseini, Prof. Eric Wei-Guang Diau, Dr. Khashayar Mehrany and Dr. Nima Taghavinia
Article first published online: 18 SEP 2014 | DOI: 10.1002/cphc.201402505
On reflection: Luminescent downshifting is a photon management technique that can be used in transmissive (front of the cell) or reflective configurations (back of the cell; see picture, QE=quantum efficiency). Optical loss analysis of the two configurations proves the reflective configuration to be more effective.

Article first published online: 18 SEP 2014 | DOI: 10.1002/cphc.201402585
First steps of H2 production: The light-induced excited state processes, accompanied by a structural change, of several heteroleptic copper(I) complexes are discussed with respect to their application as noble-metal-free photosensitizers in proton reducing systems.

Pucker up: Local molecular motions in the plastic crystal [C2 mpyr][BF4] are studied by a combination of quantum chemical calculations and advanced solid-state nuclear magnetic resonance spectroscopy. In the low-temperature solid phase, restricted puckering motion with a small fluctuation angle of 25° is observed in the pyrrolidinium ring.
