An amperometric biosensor for the determination of glycated hemoglobin in human whole blood is proposed. The principle is based on the electrochemical measurement of ferroceneboronic acid (FcBA) that has been specifically bound to the glycated N-terminus. Hemoglobin is immobilized on a zirconium...

A voltammetric determination of possible organic pollutants such as diol and phenolic compounds in water was studied using ferroceneboronic acid (FBA) as a redox-active marker. A cyclic voltammogram of FBA exhibited a pair of oxidation and reduction peaks at 230 and 170 mV at pH 7.0, respectivel...

Ferroceneboronic acid (FcBA) was used as a redox-active probe suitable for monitoring of diol–boronate interactions. Voltammetric and amperometric measurements allowed to detect FcBA forms – free and bound in the boronate complex. In this way, the complexation interaction was studied for a set...

Ferroceneboronic acid (FcBA) was employed as a model compound for clarification of binding and signalling properties of molecular probe for saccharides. As the simplest electrochemically active boronic acid, its interactions with diverse diols were studied in homogeneous phase under aqueous and ...

The low temperature γ-irradiation of norbornadiene and (1,5-ciclooctadiene) platinum(II) dichloride in methyltetrahydrofurane matrix leads to a selective production of electron capture centres which were identified by ESR as platinum(I) diolefin radical anions. The Molecular Orbital calculation...

The effects of high external pressures on the principal IR and Raman bands of crystalline dichloro(1,5-cycloctadiene)platinum(II), Pt(COD)Cl2 (COD = η4-C8H12), have been investigated for pressures up to ∼30 kbar by diamond-anvil cell microspectroscopy. This square-planar Pt(II) complex does no...

Phenylation of dichloro-μ4-norbornadienepalladium either with diphenylmercury or, more conveniently, with sodium tetraphenylborate gave di-μ-chlorobis(2:5.6-μ-3-endo-phenylnorbornen-2-yl-endo-palladium) (IV). This reaction provides the first definitive evidence for a cis addition of Pd-R to a...

Microwave and spark plasma sintering processes were used to produce magnesium-B4C metal matrix composites by powder metallurgy route. Magnesium powder with 5 wt% B4C in ethanol media was blended in a high-energy ball mill for 10 min. The sintering process was performed at 500° and 670 °C using...

In this experimental study, magnesium (AZ91D) based boron carbide (B4C) and graphite (Gr) particle reinforced hybrid composite materials were manufactured by stir casting.
