Lucigenin hexacyanoferrates

Russian Journal of Inorganic Chemistry, 2008
The reaction of lucigenin (Lc) with potassium hexacyanoferrate is accompanied by the appearance of charge-transfer bands in the visible spectral region and yields Lc{H}2[Fe(CN)6] · 4H2O in an acidic medium and Lc4[Fe(CN)6](NO3)5 · 18H2O in a neutral medium in air.

Inhibition of transketolase by hexacyanoferrate(III)

Biochemistry (Moscow), 2010
The effect of hexacyanoferrate(III) on the catalytic activity of transketolase has been studied. This oxidant inactivates only one of two active sites of the enzyme, the one with a higher affinity to the coenzyme (thiamine diphosphate). The second active site does not lose its catalytic activity.

Development of biosensors based on hexacyanoferrates

Talanta, 2000
Ferric and copper hexacyanoferrates (PB and CuHCF, respectively) were electrodeposited on glassy carbon electrodes providing a suitable catalytic surface for the amperometric detection of hydrogen peroxide. Additionally glucose oxidase was immobilized on top of these electrodes to form glucose biosensors.

A conductivity study of dilute aqueous solutions of tetramethylammonium hexacyanoferrate(III), tetraethylammonium hexacyanoferrate(III) and benzyltrimethylammonium hexacyanoferrate(III)

Journal of Molecular Liquids, 2017
Electrical conductivities of tetramethylammonium hexacyanoferrate(III), tetraethylammonium hexacyanoferrate(III) and benzyltrimethylammonium hexacyanoferrate(III) in dilute aqueous solutions, in the 278.15 K to 313.15 K temperature range are reported. These conductivities are examined in terms of the molecular model which includes an existence of three

Hierarchically Designed Cathodes Composed of Vanadium Hexacyanoferrate@Copper Hexacyanoferrate with Enhanced Cycling Stability

ACS Applied Materials & Interfaces, 2020
Prussian blue analogues (PBAs) have been highlighted as electrode materials for aqueous rechargeable batteries (ARBs) because of their favorable crystal structure and electrochemical activity. However, dissolution of the transition-metal ions during cycling degrades the materials and hinders the development of long-life-span batteries. To overcome this

Photoresponse of indium hexacyanoferrate

Solar Energy Materials and Solar Cells, 1993
Abstract Formation of insoluble metal hexacyanoferrate films on chalcogenide semiconductor materials in ferrocyanide medium has been found to be responsible for enhanced photocurrents and inhibition of photocorrosion. Similar beneficial properties recorded by us for the first time on indium hexacyanoferrate in ferrocyanide medium and explained in ...
