Nanoengineering of inorganic and hybrid composites
(Materials Science Forum, 2000)
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 ...
Colloid particles and advanced materials
(Materials Science Forum, 1996)
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, ...
Modification of carbon cloth by interaction with pulsed TEA CO2 laser
(Materials Science Forum, 2004)
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 ...
Thermal diffusivity of cold sintered Co
(Materials Science Forum, 2004)
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 ...
Hyperbolic propagation of a thermal signal in an inhomogeneous medium
(Materials Science Forum, 2005)
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 ...
Comparison of hydroxyapatite sorption properties towards cadmium, lead, zinc and strontium ions
(Materials Science Forum, 2005)
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 ...
The influence of the solid/liquid ratio on the point of zero charge of alumina
(Materials Science Forum, 2004)
The point of zero charge (pH(pzc)) of three samples of commercial aluminum oxide in aqueous KNO3 (10(-3) - 10(-1) mol/dm(3)) solution was investigated using batch equilibration, mass titration and acid-base titration ...
Hot pressing of Y2O3 doped Si3N4 ceramics
(Materials Science Forum, 2005)
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 ...
The effect of reversing current on the properties of copper and electrolytic copper powder II. The apparent density and flowability of powders
(Materials Science Forum, 2004)
The apparent density and flowability of copper powder are related to the structure of powder particles and the reversing current (RC) regimes. It was shown that the apparent density of the powders increases with the increase ...
Curing characteristics and dynamic mechanical behaviour of reinforced acrylonitrile-butadiene/chlorosulfonated polyethylene rubber blends
(Materials Science Forum, 2005)
This paper deals with the control of the adhesion strength in metal-elastomer joints by fillers and the use of rubber blends to produce advanced high performance adhesive systems. The curing behavior of rubber compounds ...
