To the Editor: We read with interest a paper on phospholipid analysis in this journal (1) but deferred comment until the publication of our own paper on the subject, which we believe contains relevant material (2). Sandhu refers to the formation of a Prussian blue complex as the result of a reaction between phospholipids and a chromogenic reagent containing molybdenum. Clearly this cannot be so...

Carbon film resistor electrodes have been evaluated as transducers for the development of multiple oxidase-based enzyme electrode biosensors. The resistor electrodes were first modified with Prussian Blue (PB) and then covered by a layer of covalently immobilized enzyme. Electrochemical impedance spectroscopy was used to characterize the interfacial behaviour of the Prussian Blue modified and e...

In the article we intend to present some recent achievements in the chemistry and physics of 3d and f electron mixed valence systems based on the Prussian blue in the field of molecular magnetism. Prussian blue is sometimes considered as the first coordination compound and in the paper we would like to demonstrate how it is possible to obtain completely new results based on the old one compound.

Negative charged sites in the normal rabbit articular cartilage were investigated using cationic colloidal iron methods. In light microscopy of the cartilage stained with the colloidal iron at pH 1.5, a distinct Prussian blue reaction was observed in the pericellular matrix, and a weak blue reaction in the territorial and interterritorial matrices. At pH 7.0, a diffuse Prussian blue reaction wa...

This paper reports on molecular-based magnetic thin films of Prussian blue analogues (PBA) with high critical temperatures composed of mixed-valence chromium cyanides. The thin films of PBA were synthesized by means of electrodeposition technique. Morphology and magnetic study are presented in a function of electrochemical deposition conditions. We present the electrochemical methods as a promi...

Prussian blue and its analogues consisting of different transition-metal ions (Fe, Mn, Ni, Cu, Co and Zn) have been synthesized at room temperature. Insertion of Na into KFe(2)(CN)(6) in a carbonate electrolyte exhibited a reversible capacity near 100 mA h g(-1) with no capacity fade in 30 cycles. The data indicate that a Na-ion battery with a Prussian blue framework as a cathode will be feasible.

There is an increasing interest in studying still more complicated magnetic systems. A group of ternary mixed alloys is, among them, a point of interest for as well historical as scientific reasons. The most known material belonging to this group is the famous pigment Prussian blue. The Prussian blue analogues may be characterized by special properties, like the existence of compensation points...

The electronic spectra, electrical conductivity, magnetism, and gas adsorption properties of the newly prepared Prussian blue analogues Fe4[Ru(CN)6]3 · 18H2O (2) and K1.2Ru3.6[Ru(CN)6]3 · 16H2O (3) are compared with those of Prussian blue itself (Fe4[Fe(CN)6]3 ·14H2O, 1). The increase in the degree of electronic localization for the unsymmetrical iron-ruthenium analogue 2 is reflected in a shif...

A highly ordered two-dimensional hybrid magnetic nanocomposite has been prepared by synthesizing and intercalating a new cationic aluminum-hydroxy ferric ferrocyanide compound into a cation-adsorbing nanoclay (montmorillonite). Chemical and structural properties were investigated by X-ray diffraction, transmission electron microscopy, thermogravimetric and differential thermal analyses, Fourier...
