Fabrication of SiC by carbothermal-reduction reactions of sepiolite
(Materials Science Forum, 2007)
The objective of this manuscript was to investigate the synthesis of SiC by carbothermal-reduction reactions of sepiolite. Sepiolite of Serbian origin and carbon (from various precursors) as a reducing agent were used. The ...
Particle-in-cell modelling of a neutral beam source for material processing in nanoscale structures fabrication
(Materials Science Forum, 2007)
Neutral beam processing has evolved into one of the most promising methods for overcoming plasma process induced damage. Surface treatment by neutrals avoids problems with surface charging effects, frequently encountered ...
Dielectric and ferroelectric properties of BaTi1-xSnxO3 multilayered ceramics
(Materials Science Forum, 2007)
Multilayered BaTi1-xSnxO3 (BTS) ceramics with different Ti/Sn ratios were produced by pressing and sintering at 1420 degrees C for 2 hours. X-ray diffractometry, scanning electron microscopy and energy dispersive spectroscopy ...
Influence of charging on SiO2 etching profile evolution etched by fluorocarbon Plasmas
(Materials Science Forum, 2007)
A comprehensive simulation of etching profile evolution requires knowledge of the etching rates at all points of the profile surface during the etching process. Electrons do not contribute directly to the material removal, ...
Low-temperature synthetic route for boron carbide powder from boric acid-citric acid gel precursor
(Materials Science Forum, 2007)
Boron carbide powder was synthesized by sol-gel polycondensation of boric acid with citric acid. The starting materials of Serbian origin were dissolved in water and mixed homogeneously until a precomposite gel was formed, ...
Changes in structure and properties of oligophenylenes under selected external influences
(Materials Science Forum, 2007)
Effects induced by uniaxial compression and external electric field in P2P to P6P oligophenylene molecules are investigated by versatile calculations. In this way some useful relations between particular values of compression ...
Delamination strain energy release rate in carbon fiber/epoxy resin composites
(Materials Science Forum, 2007)
The paper reports on an experimental study of the Mode I interlaminar fracture of unidirectional carbon fibers/epoxy resin composites. Mode I delamination strain energy release rate G(IC) was determined in double cantilever ...
Rietveld refinement of crystal phases (Ca1-xLax)MnO3 with perovskite-type structure
(Materials Science Forum, 2007)
Two nanopowders with nominal compositions (Ca0.7La0.3)MnO3 (CLM) and (Ca0.7La0.3)(Mn0.8Ce0.2)O-3 (CLMC) were synthesized by a modified glycine/nitrate procedure. XRD analysis revealed binary phase mixture in both samples. ...
Adsorption of some weak organic electrolytes from aqueous solutions on silica
(Materials Science Forum, 2007)
The adsorption of organic electrolytes from aqueous solutions on various adsorbents has been frequently investigated because of its importance in water purification. Phenol and substituted phenols are very common contaminants ...
The stabilizer influence on morphological characteristics of poly-(DL-lactide-co-glycolide) nanospheres
(Materials Science Forum, 2007)
Copolymer poly(D,L-lactide-co-glycolide) is used for obtaining the systems for controlled delivery of medicaments. Its specific characteristics make it suitable for various researches where its synthesis is performed in ...
