The dissociation of apoferritin into subunits at pH 2 followed by its re-formation at pH 8.5 in the presence of hexacyanoferrate(III) gave rise to a solution containing hexacyanoferrate(III) trapped within the apoferritin and hexacyanoferrate(III) outside it. The addition of Fe(II) to the dialyzed solution resulted in the appearance of the characteristic Prussian blue color. The UV-vis spectrum...

Copper hexacyanoferrate (CuHCF) is a promising Zn2+ insertion material as positive electrode in mild aqueous Zn-ion batteries for power grid applications, due to its excellent capability, non-toxicity, low cost and easy synthesis route. Here, the effect of reactants’ concentration ratio during CuHCF on performance resulting has been investigated through morphological, crystallographic compositi...

The transaldolase-dihydroxyacetone carbanion intermediate formed in the reaction of transaldolase with its donor substrates fructose-6-P or sedoheptulose-7-P is susceptible to oxidation by hexacyanoferrate(III). The dihydroxyacetone moiety is oxidized to the corresponding 2-ketoaldehyde, i.e. hydroxy-pyruvaldehyde (CH2OH-CO-CHO). This oxidation product is, in contrast to dihydroxyacetone, readi...

We synthesized a variety o f colloidal and non-colloidal mixed hexacyanoferrate(II) com plexes of Fe, C u, C o, Ni, Z n . Mn and studied the cesium sorption in vitro under physiological conditions (artificial gastric juice. pH 1.2 and artificial duodenal ju ice. pH 6.8). All of the hexacyanoferrates under study (except cesium iron (III) hexacyanoferrate C sFeH C F) sorb tracer am ounts of 1'7Cs...

The transaldolase-dihydroxyacetone carbanion intermediate formed in the reaction of transaldolase with its donor substrates fructose-6-P or sedoheptulose-7-P is susceptible to oxidation by hexacyanoferrate(II1). The dihydroxyacetone moiety is oxidized to the corresponding 2-ketoaldehyde, i.e. hydroxypyruvaldehyde (CH,OH .CO ‘CHO). This oxidation product is, in contrast to dihydroxyacetone, read...

A glassy carbon electrode was modified with graphene oxide nanosheets and a hybrid of copper-cobalt hexacyanoferrate. The nanocomposite was characterized by cyclic voltammetry, FT-IR and scanning electron microscopy. Cyclic voltammetry showed a stable and reversible redox pair with surface confined characteristics in phosphate buffer solution (0.1 M, pH 3). Hydrodynamic amperometry was used for...

Copper hexacyanoferrate (CuHCF) has become an attractive Zn2+ insertion material as a positive electrode in aqueous zinc-ion batteries thanks to its high reversibility towards (de-)insertion, simple, inexpensive and easily scalable synthesis route, low toxicity, working potential. It is known that the physiochemical properties of CuHCF can be modified by manipulating parameters. However, effect...
