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.

- Nonuniform Continuum Model for Solvatochromism Based on Frozen-Density Embedding Theory
Dr. Sapana Vitthal Shedge and Prof. Tomasz A. Wesolowski
Article first published online: 29 AUG 2014 | DOI: 10.1002/cphc.201402351
Simplifying solvents: Frozen-density embedding theory (FDET) has been developed to include a statistically averaged electron density of the solvent. The model has been used to investigate specific solute–solvent interactions and to accurately describe solvatochromic shifts in both absorption and emission.

Article first published online: 28 AUG 2014 | DOI: 10.1002/cphc.201402103
You can print anything these days: A simple and general solvent exchange technology is introduced for inkjet printing of 2D layered materials. The technology addresses the critical challenges and improves the manufacturing efficiency and product quality. Excellent jetting performance, ideal printing patterns and a variety of promising applications for inkjet printing of 2D layered materials are demonstrated.
- Assessments of Semilocal Density Functionals and Corrections for Carbon Dioxide Adsorption on Metal–Organic Frameworks
Hyunjun Ji, Joonho Park, Moses Cho and Prof. Yousung Jung
Article first published online: 28 AUG 2014 | DOI: 10.1002/cphc.201402291
COO-ing over MOFs: An accurate yet economical description of CO2–metal–organic framework (MOF) is a topical issue in computational science. In this minireview, several generalized gradient approximation (GGA)-based functionals are assessed, and the individual effects of the components of the GGA methods (dispersion correction, Hubbard U correction, and exchange functional) are discussed.
- On the Origin of Damped Electrochemical Oscillations at Silicon Anodes (Revisited)
Prof. Joris Proost, Frédéric Blaffart, Dr. Stuart Turner and Dr. Hosni Idrissi
Article first published online: 27 AUG 2014 | DOI: 10.1002/cphc.201402207
Seeing is believing: A widely accepted model of oxide growth during galvanostatic anodizing of Si in fluoride-free electrolytes is questioned by revisiting the underlying seminal experiment carried out about two decades ago. As such, the fundamental hypothesis of a stress-induced morphological transition of the anodic oxide accompanying the damped electrochemical oscillations is disproven.
