A non-heme iron complex catalyses the oxidation of allylic, benzylic, and aliphatic C-H bonds by O(2). During this reactivity, a ferric hydroperoxide species is observed. The kinetic analysis of this complex's formation may suggest a ferric superoxo species as the initial metal-based oxidant.

This review focuses on recent advances in the post-synthetic modification of nano-sized Prussian blue and its analogues compares them with current strategies used metal–organic frameworks to give future outlooks this field.

The molecular magnet material, cobalt-Prussian Blue, has been synthesized using chitosan as a morphological structure-directing agent. The strong chelating ability of the biopolymer ensures that the inorganic phase remains nanoparticulate. SQUID magnetometry reveals that the nanoparticles exhibit a sharp ferrimagnetic to paramagnetic transition at 16 K.

We found that the alignments of the alkali cations can be controlled by a distortion of Prussian blue framework; the rubidium ions form a rod structure in a distorted framework of Rb(0.85)Cu[Fe(CN)(6)](0.95)·1.3H(2)O, while the cesium ions are isolated dot structures in a non-distorted framework of Cs(0.97)Cu[Fe(CN)(6)](0.99)·1.1H(2)O. The Madelung energy calculations revealed that the novel ro...

A quantitative analysis is presented for the site-selective Fe K-edge absorption spectra of Prussian Blue: Fe(4)[Fe(CN)(6)](3) x xH(2)O (x = 14-16). The site-selective spectra were recorded using high-resolution fluorescence detection of the K beta emission from a polycrystalline sample. The K beta fluorescence lines arising from the high-spin and low-spin sites are shifted in energy. Since the...

NOMOGRAMS ARE used regularly in our laboratory for various routine calculations (1). A frequent calculation, which may be performed rapidly with the nomogram presented here, is typified by the colorimetric determination of glucose concentration with a reaction in which absorbance decreases as glucose concentration increases (Figure 1). The system uses an AutoAnalyzer and depends upon the reduct...

A spectrophotometric flow-injection analysis (FIA) system for monitoring clinical hemodialysis is demonstrated. The role of a dialysate urea detector incorporated in this bioanalytical system is played by an optical flow-through biosensor based on Prussian Blue film with chemically linked urease forming a monomolecular layer of the enzyme. This pH-enzyme optode-FIA system is useful for the sele...

In the present work, Prussian blue analogues, Mn[Fe(CN)6]0.6667·nH2O (Mn-PBA), were synthesized by a simple synthetic route and characterized by XRD, SEM, TEM, FTIR and TGA. When this material was firstly used as an anode for lithium-ion batteries, it exhibited a large capacity, good rate capability and cycling stability with a high Coulombic efficiency. For instance, a reversible capacity of 2...
