Abstract Calcium phosphate bions (CPB) are biomimetic mineralo-organic nanoparticles which represent a physiological mechanism regulating the function, transport and disposal of calcium phosphorus in human body. We hypothesised that CPB may be pathogenic entities even cause cardiovascular calcification. Here we revealed isolated from calcified atherosclerotic plaques artificially synthesised morphologically chemically indistinguishable entities. Their formation is accelerated along with...
An association between high serum calcium/phosphate and cardiovascular events or death is well-established. However, a mechanistic explanation of this correlation lacking. Here, we examined the role calciprotein particles (CPPs), nanoscale bodies forming in human blood upon its supersaturation with calcium phosphate, disease. The patients coronary artery disease cerebrovascular displayed an increased propensity to form CPPs combination elevated ionised as well reduced albumin levels,...
Nanocomposites based on poly(styrene-block-isobutylene-block-styrene) (SIBS) and single-walled carbon nanotubes (CNTs) were prepared characterized in terms of tensile strength as well bio- hemocompatibility. It was shown that modification CNTs using dodecylamine (DDA), featured by a long non-polar alkane chain, provided much better dispersion SIBS compared to unmodified CNTs. As result such modification, the nanocomposite with low molecular weight (Mn = 40,000 g mol-1) containing 4%...

Abstract In this work, on the example of bimetallic systems FePt and FePd, an approach is developed to assessing structural parameters nanoscale mono-and polymetallic by transmission electron microscopy (TEM), in comparison with X-ray diffraction method analysis. The interplanar distances, average sizes phase compositions FePd nanosystems are calculated.
This study is aimed at elucidating the fractional composition, volume and toxicity of dust that deposited in snow cover for period accumulation different distances from coal mines a coal-fired power station Kemerovo region (Russia). During filtration process, fractions 10–0.1 µm less than 0.1 were isolated weighed. Light microscopy was used to estimate size particles fraction. We found total composition has no significant trend change research space. The contamination associated mainly with...
This paper reveals and describes the features of NicoreAushell nanoparticles' magnetic properties. Their activation energy monodomain thermal relaxation (5.1 × 10–20 J) constant crystalline anisotropy ((2.0–2.1) 104 J/m3) are higher than bulk nickel has. Compared with nanostructured fcc-Ni powders, there is a decrease in coercive force, presence "hard" magnetization, rising magnetization along increasing degree oxidation, characteristics to very low values at 300 K. These related structure...
The surface plasmon resonance of gold nanoparticles in a polycrystalline energy-related material – pentaerythritol tetranitrate (PETN) has been observed for the first time. extinction spectra this are recorded, and its absorption characteristics determined by photoacoustic method using pulsed laser irradiation. Using data obtained, it is concluded that promising inclusions explosive materials when designing an optical detonator.
Abstract Joint reduction with hydrazine from aqueous solutions of precursors produced nanostructured powders the Fe – Pt system in three characteristic phase regions.
