Transmission electron microscopy of interfaces in structural ceramic composites
(Blackwell Science LTD, 1999)Ceramic composites based either on a particulate, fibre or a lamellar architecture are potentially useful as damage-tolerant high-temperature engineering materials. The ability of the interfaces in such systems to deflect ... -
Capacitor-discharge joining of oxide ceramics
(Amer Ceramic Soc, 1999)A capacitor-discharge joining technique has been used to fabricate alumina-metal-alumina and zirconia-metal-zirconia joints using thin foils of aluminum, titanium, or amorphous AlxNiyYz alloys as interlayers. The technique ... -
Biochemical profile of those who are subject to the industrial wastes of battery factories in Eskisehir
(Mbr Press Inc, 1999)Lead poisoning is one of the most important which among professional diseases. The industries which causes environmental lead pollution are lead mining, lead metalurgy, battery manufacturing, ship parts, cristal glass ... -
Electron microscopy studies of municipal sludge contaminated marine clay
(IOP Publishing LTD, 1999)The effects of municipal sludge on physico-chemical and microstructure of laboratory prepared marine clay sediments were investigated. Experiments were conducted on artificially prepared marine sediments to investigate ... -
Optimum conditions for the precipitation of chitosan oligomers with DP 5-7 in concentrated hydrochloric acid at low temperature
(Elsevier Sci LTD, 1999)Chitosan was partially hydrolysed with 35% hydrochloric acid for 2 h at 80 degrees C and the hydrolysate stored at - 20 degrees C after dilution with water to precipitate higher molecular weight (MW) chitosan oligomers. ... -
Identification of the different sources of chlorides in streams by regression analysis using chloride-discharge relationships
(Water Environment Federation, 1999)Chloride-discharge relationships at several stations on Turkish streams are investigated, both qualitatively and quantitatively, to identify natural and anthropogenic sources of chloride. Simple expressions are used to ... -
New developments in alpha-SiAlON ceramics
(Elsevier Sci LTD, 1999)Two different alpha-sialon compositions have been densified by either pressureless sintering or capsul-free sinter HIPing using either single cation namely strontium, lanthanum, cerium, neodymium or their equimolar mixtures ... -
Wetting and non-wetting behaviour of silicon carbide grain boundaries
(Transtec Publications LTD, 1999)Silicon carbide (SiC) grain boundaries have been observed to be free from intergranular films. On the basis of equilibrium film thickness calculations, it has been proposed elsewhere that because SiC has very high refractive ... -
Melting behaviour of glasses in the SrO-MgO-ZrO2-SiO2 system
(Soc Glass Technology, 1999)In the SrO-MgO-ZrO2-SiO2 system a large range of compositions with 60, 55, 50, 45, 40 and 35 wt% silica has been thoroughly investigated The effect of silica and other constituents on melting, annealing and colour variations ... -
Piezoelectric hollow spheres for microprobe hydrophones
(Taylor & Francis LTD, 1999)Miniature hollow spheres of lead zirconate titanate have been prepared with a coaxial nozzle process using fine grain slurry of PZT-5. Following the binder burnout and sintering, the spheres were poled radially and ... -
alpha ->beta sialon transformation in calcium-containing alpha-SiAlON ceramics
(Elsevier Sci LTD, 1999)Recent studies on rare earth densified a-sialon ceramics have shown that the resulting alpha-sialon product, present either as a single phase or in conjunction with beta-sialon, is unstable when heat treated at lower ... -
Composition of the essential oil of Plumeria obtusa L.
(John Wiley & Sons LTD, 1999)The essential oil of fresh flowers of Plumeria obtusa L. collected in Brunei Darussalam was isolated by hydrodistillation and examined by GC-MS. Forty-seven components were identified, representing 97% of the oil, with ... -
