(Elsevier Science BV, 2004)Sesame stalk pyrolysis experiments were conducted in a fixed-bed reactor in an attempt to determine the effects of pyrolysis temperature, particle size, heating rate and sweeping gas (N-2) flow rate on the product yields ... -
A Statistical Study of Fatigue Life Prediction of Fibre Reinforced Polymer Composites
(Ismithers, 2011)In this study, the tension-tension fatigue response of bidirectional woven E-glass fibre reinforced unsaturated polyester composites was experimentally determined. The composite parts were produced via continuous laminating ... -
Processing and characterisation of three-layer alumina-based composites with enhanced damage tolerance
(Elsevier Sci LTD, 2005)Three-layer alumina-based composites reinforced with iron in the inner layer and with chromium in the outer layers were fabricated by first uniaxially pressing the three-layer assembly, followed by cold isostatic pressing ... -
The use of pumice (pumicite) in transparent roof tile glaze composition
(Elsevier Sci LTD, 2006)In this study, the use of pumice as an alternative fluxing agent instead of Na-Feldspar in the transparent roof tile glaze composition was investigated. The experiments were designed as a mixture experiment. According to ... -
Electrophoretic deposition of nano-sized BaTiO3
(Springer, 2006)In this study, a non-aqueous method in a simple one pot reaction process was employed to synthesize nano-sized BaTiO3 particles and then electrophoretic deposition technique was employed for thin film coatings. In the first ... -
Electrophoretic deposition of nanocrystalline BaTiO3 in ethanol medium
(Trans Tech Publications LTD, 2006)Electrophoretic deposition technique is a versatile coating method. With this method not only flat surfaces but also curved or rough surfaces can be coated in various thicknesses. In this study, BaTiO3 nanocrystals were ... -
Use of tuncbilek thermal power plant's fly ash in stoneware glazes as a colouring agent
(Trans Tech Publications LTD, 2004)With the increased energy needs thermal power plants enlarge their production rates. In spite of high productivity in energy supplies, the concentration of fly ash filtered in the chimneys of these plants raises subsequently. ... -
Production of bio-fuels from cottonseed cake by catalytic pyrolysis under steam atmosphere
(Pergamon-Elsevier Science LTD, 2006)The purpose of this study is to evaluate the amounts of catalytic pyrolysis products of cottonseed cake in steam atmosphere and investigate the effects of both zeolite and steam on pyrolysis yields. The effect of steam was ... -
