Four different types of high-density polyethylenes were blended with expanded perlite at different compositions. Gamma-aminopropyltriethoxysilane was applied to perlite (2 wt%) from ether and water solutions to enhance the interfacial adhesion between the polymer and the filler. It was shown that silane treatment advances the yield stress with improving dispersion and increasing the interfacial adhesion of the filler with the polymer matrix. The experimental results were then checked with the expression of Turcsanyi et al.'s.

Investigation of microstructure-ultrasonic velocity relationship in SiCp-reinforced aluminium metal matrix composites Gür, Cemil Hakan (Elsevier BV, 2003-11-25) Twenty-one sets of specimens were fabricated by hot pressing powder mixtures containing various volume and size combinations of pure Al and SiC particles. Neither heat treatment nor secondary deformation processes were applied. The microstructures of the specimens were characterised by optical and scanning electron microscopy. Using a 10 MHz probe, the velocity of ultrasonic longitudinal waves was measured. The results show that in general the ultrasonic velocity increases with an increase in SiC content. H...
A study of phase stability and mechanical properties of hydroxylapatite-nanosize alpha-alumina composites Evis, Zafer (Elsevier BV, 2007-04-01) Hydroxylapatite (HA)-nanosize alumina composites were synthesized to study their phase stability and mechanical properties. To make these composites, nanosize alpha-Al2O3 powder was used because of its better sinterability and densification as compared to nanosize gamma-Al2O3. The composites were air sintered without pressure and hot pressed in vacuum at 1100 degrees C and 1200 degrees C. In the composites, HA decomposed to tricalcium phosphate faster after the air sintering than hot pressing. Moreover, hex...
AN EXPERIMENTAL INVESTIGATION OF POLYVINYL-CHLORIDE) EMULSION POLYMERIZATION - EFFECT OF INITIATOR AND EMULSIFIER CONCENTRATIONS ON POLYMERIZATION KINETICS AND PRODUCT PARTICLE-SIZE Karakaş, Gürkan (Wiley, 1989-01-01) Effects of concentration changes in initiator species Na2SO3, (NH4)2S2O8 and CuSO4, and emulsifier, ammonium stearate, on poly(vinyl chloride) (PVC) emulsion polymerization kinetics and on product particle size were experimentally investigated. It was observed that to obtain industrially significant rates and overall conversions, not only an optimum concentration ratio of Na2SO3/(NH4)2S2O8/CuSO 4 must be used, but also the concentrations of these species must be above certain limits. Increasing the concentr...
A novel, simple, organic free preparation and characterization of water dispersible photoluminescent Cu2O nanocubes Zahmakiran, Mehmet; Özkar, Saim; Kodaira, Tetsuya; Shiomi, Toru (Elsevier BV, 2009-02-15) A novel method was developed for the organic and polymer free preparation of Cu2O nanocubes. Water-dispersible Cu2O nanocubes were prepared at room temperature by using a simple two steps procedure: the reduction of copper(II) sulfate by sodium borohydride generates the copper(O) nanoclusters stabilized by hydrogenphosphate towards the aggregation in aqueous solution. The hydrogen phosphate stabilized copper(0) nanoclusters initially formed are slowly oxidized by dissolved oxygen forming the Cu2O nanocubes ...
A SURVEY OF FATIGUE CRACK-GROWTH LIFE ESTIMATION METHODOLOGIES AKYUREK, T; BILIR, OG (Elsevier BV, 1992-07-01) In this study, three fatigue crack growth life estimation methodologies are reviewed and sample calculations are made using these methodologies. Comparisons of the results with respect to the methodologies are made. Three computer codes which represent these methodologies, CRACKS IV, FAST and FATIGUE, are selected for the analyses. The estimations are also correlated to the test results.
