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.

Implantable biofuel cells: The main concepts and challenges in enzyme biofuel cells (BFCs) research are introduced. Some important topics in kinetics and thermodynamics applied to BFCs are also discussed. Wherever possible, an extensive review of work undertaken in recent years is performed. Topics covered include thermodynamics, kinetics and challenges in applicability.
- Fundamental Properties of Phenylboronic-Acid-Coated Gate Field-Effect Transistor for Saccharide Sensing
Dr. Taira Kajisa and Prof. Toshiya Sakata
Article first published online: 1 SEP 2014 | DOI: 10.1002/celc.201402193
Sweet, sweeter, sweetest! To detect various kinds of saccharides with high sensitivity, mono-, di-, and nucleotide saccharides are detected using a phenylboronic-acid (PBA)-coated gate field-effect transistor. The gate voltage changes in response to sugar concentrations, and the affinity of PBA is different for sugars at higher concentration, although it is less selective at lower concentration.
- The Mtr Pathway of Shewanella oneidensis MR-1 Couples Substrate Utilization to Current Production in Escherichia coli
Dr. Michaela A. TerAvest, Tom J. Zajdel and Dr. Caroline M. Ajo-Franklin
Article first published online: 29 AUG 2014 | DOI: 10.1002/celc.201402194
Anatomy of an E. coli: The coupling of the MtrCAB-CymA electron conduit to central metabolism in E. coli is studied. An electrode poised at an anodic potential acts as a terminal electron acceptor that relieves buildup of reducing equivalents during anaerobic lactate metabolism.
- High-Performance, Totally Flexible, Tubular Microbial Fuel Cell
Majid Taghavi, Prof. John Greenman, Dr. Lucia Beccai, Dr. Virgilio Mattoli, Dr. Barbara Mazzolai, Prof. Chris Melhuish and Prof. Ioannis Andrea Ieropoulos
Article first published online: 29 AUG 2014 | DOI: 10.1002/celc.201402131
Put to good use: Various tubular microbial fuel cells (MFCs) are fabricated using carbon veil and carbon sleeve as the anode electrode in addition to cation exchange membrane and Nafion as the membrane. They are characterised while being fed with urine, resulting in a high-performance totally flexible MFC.
