The effect of seeding on the microstructure and mechanical properties of hot-pressed silicon nitride was investigated by introducing large, elongated beta-Si3N4 particles into an alpha-Si3N4 matrix. Densification and ...

Apatites are well known matrix for heavy metal immobilization and remediation of ground water and contaminated soils. In this work, capacities of different synthetic hydroxyapatite (HAP) samples for Pb, Cd, Sr and Zn ...

This review reveals certain aspects of the preparation, properties, and applications of monodispersed metal (hydro) oxide sols. Methods for preparation of well defined colloidal metal oxides (including those of silicon, ...

A numerical procedure for the calculation of space distribution of the thermal field in thermally inhomogeneous solids with thermal memory induced by a harmonically modulated surface heat source is presented. The procedure ...

The engineering of materials and devices on the nanometer scale is of considerable current interest in electronics, optics, catalysis, ceramics and magnetic storage. Different methodologies of processing that lead to the ...

Cd1-xMnxS quantum dots (QDs) of 4.5 nm average size with various compositions, from x = 0.001 to x = 0.15, have been synthesized by using aqueous solution precipitation. Diluted magnetic semiconductor (DMS) quantum dots ...

The interaction of a Transversely Excited Atmospheric (TEA) CO2 laser (pulse duration less than 2 mus) with carbon and activated carbon cloth was investigated. The investigations have shown that carbon cloth had been ...

Cd1-xMnxS quantum dots (QDs) with a diameter d less than or equal to 4.5 nm and manganese concentration from x 0.001 to x 0.15 have been prepared using aqueous Solution precipitation. The EPR measurements have been performed ...

Cold sintering of cobalt powder (up to 1.2 GPa) was accompanied by measurements of density and thermal diffusivity. Dependence of density change upon pressing pressure is derived. Thermal diffusivity of the material was ...

Electron paramagnetic resonance (EPR) linewidth in the Cd1-xMnxS bulk crystals with manganese concentrations x = 0.25, 0.33, 0.35 and 0.42 has been studied in the high-temperature region. An analysis of the infinite-temperature ...
