ChemElectroChem 07/2014: Materials and Methods
Issue 7 contains a mixture of reviews, full papers, and communications covering very different areas in electrochemistry. In a Review, B. Van der Bruggen and colleagues describe "electrokinetic remediation" as a suitable technique for the restoration of saline soil and the control of seawater intrusion. In the Articles section, J. Roncali and co-workers report on the production of nanostructured conjugated polymers by electropolymerization of tailored tetrahedral precursors, and D. S. Silvester, D. W. M. Arrigan et al. present their results on the electrochemical characterization of an oleyl-coated magnetite nanoparticle-modified electrode. The Communication by P. Schmuki and colleagues shows that controlled thermal annealing can tune the photoelectrochemical properties of nanochanneled tin-oxide structures.

The ferrocene-terminated Si (Si-Fc) as diodes: The diode nature of Si-Fc samples is attributed to the existence of a potential barrier between the Si substrate and the ferrocene layer. The diode nature of Si-Fc samples can be associated with some of its characteristics, such as the dependence of its cyclic voltammetry response on types of substrate and illumination.
- Cathodic Corrosion of Cu Substrates as a Route to Nanostructured Cu/M (M=Ag, Au, Pd) Surfaces

Feeling rusty: Electrodeposition of Ag, Au or Pd onto a Cu electrode under hydrogen evolution conditions results in unexpected deposition of Cu within the nanostructured metal deposit. This occurs through cathodic corrosion of Cu, which provides a source of Cu ions that can be reduced during the deposition process. The morphology of the final porous material and Cu content are highly dependent on the metal salt in solution, which impacts on the catalytic performance of the material where Cu/Ag is found to be highly active.
- New Layered Proton-Conducting Oxides LixAl0.6Co0.4O2 and LixAl0.7Co0.3O2
Rong Lan and Prof. Shanwen Tao

Layer cake: Coherent insertion of protons and reduction represent the major reasons for proton conduction in layered oxides LiAl0.5Co0.5O2, LiAl0.6Co0.4O2 and LiAl0.7Co0.3O2. The proton conductivity and working temperature of the materials are closely related to the composition. It is essential to integrate multivalent elements into the layered oxide lattice to achieve high proton conductivity.
