The details of a potentiodynamic preparation method for a composite nickel(II) and copper(II) hexacyanoferrate (MeHcF) and poly[8-(3-acetylimino-6-methyl-2,4-dioxopyran)-1-aminonaphthaline] (PAMDAN) on a platinum electrode, (Pt |PAMDAN|MeHcF) are reported. The cyclic voltamograms recorded the direct deposition and growth of inner layer (PAMDAN) and the outer layer (MeHcF) from their solutions. ...

One of the first events taking place when a crystal of a metalloprotein is exposed to X-ray radiation is photoreduction of the metal centres. The oxidation state of a metal cannot always be determined from routine X-ray diffraction experiments alone, but it may have a crucial impact on the metal's environment and on the analysis of the structural data when considering the functional mechanism o...

Prussian Blue (ferric hexacyanoferrate (II)), discovered accidentally in 1706 in Berlin by Johann Jacob Diesbach (1) and Johann Konrad Dippel (2), remains an intensively investigated material. Currently, more than 200 scientific publications with Prussian Blue as a research subject are published annually. Johann Leonhard Frisch (see below) and Diesbach produced Prussian Blue in the years follow...

investigation of the redox properties of drugs and their determination are performed by electrochemical techniques. data obtained from electrochemical techniques are often correlated with molecular structure and pharmacological activity of drugs. in this regard, different modified electrodes were applied as sensors for quantification of different drugs.a nanocomposite of reduced graphene oxide-...

Consecutive thymine sequences were oxidized more efficiently with a mixture including potassium osmate, potassium hexacyanoferrate(III), and bipyridine than an isolated thymine, and, in particular, osmium oxidation at the 5'T of TT progressed much more rapidly, compared with those of other thymines.

A charge transfer between Fe and Co in cobalt hexacyanoferrate has been observed for the first time by anatase doping. The charge transfer, which involves a spin transition at the Co site, is supported by high-resolution XANES spectra. EXAFS evidenced a consistent change (10%) of the Co-N first shell.

New types of energy storage are required in conjunction with the deployment of renewable energy sources and their integration with the electrical grid. A new kind of energy storage technology is needed for short-term grid storage applications, as existing technology struggle to meet the needs of these applications at a reasonable price. We previously introduced a new family of cathode materials...

Copper hexacyanoferrate (CuHCF) nanoparticles with tunnel-like Prussian blue structure were deposited on graphite substrate via pulse galvanostatic electrochemical deposition at 25 mA cm-2 with both on-time and off-time periods of 0.1 s, which presented the ability to intercalation/de-intercalation of Al ions reversibly in aqueous solution. The crystal structure of the as-prepared CuHCF f...
