Effects of gamma-irradiation on the dielectric properties of the barium salt of 12-tungstophosphoric acid hydrate
(Materials Science Forum, 2003)
The main aim of this paper is to investigate the effects of gamma-irradiation on dielectric properties of barium salt of 12-tungstophosphoric acid (WPA) hydrate BaHPW12O40-7H(2)O (BaHWPA(.)7). Irradiation was carried out ...
Influence of the HAp ratio on the thermodynamic and kinetic parameters of PDMS/HAp composites cross-linking
(Materials Science Forum, 2003)
Injectable and gas-permeable composite cements, polydimethylsiloxane/hydroxyapatite (PDMS/HAp), were synthesized using bi-component polysiloxane precursors (RTV-A and RTV-B), which react by hydrosilylation, and different ...
Size effect in carbon fiber/epoxy resin composite
(Materials Science Forum, 2003)
Size effect in carbon fiber/epoxy resin unidirectional composites was studied, by analyzing this effect in carbon fibers, as well as, in unidirectional composites themselves. Carbon fibers were tested by the single-filament ...
Effect of powder dispersion on the stability of silicon nitride aqueous and nonaqueous suspensions
(Materials Science Forum, 2003)
Stability of aqueous and nonaqueous silicon nitride suspensions prepared in an ultrasonic bath was compared with the stability of analogous suspensions prepared by an ultrasonic disrupter. The settling velocities of the ...
Low-energy broad-beam sputter deposition of TiNx thin films
(Materials Science Forum, 2003)
The method and parameters of TiN film deposition processes are of dominant influence on the film growth microstructure and its physical properties. One of the PVD methods is the low energy ion beam reactive sputter deposition ...
Influence of the background electrolyte on the point of zero charge of chromium(III)-oxide
(Materials Science Forum, 2003)
The Point of zero charge of chromium(Ill)-oxide (pH(pzc)) was investigated by a batch equilibration method. The effect of several background electrolytes, in the concentration range of 10(-5)-10(-1) mol/dm(3), on pH(pzc) ...
Nanocrystallization and hydrogenation of amorphous Zr-Al-Cu alloys
(Materials Science Forum, 2003)
Zr-Ni-Cu-Al is not only one of the best glass forming system, but exhibits also excellent hydrogen absorption properties. In order to understand this behavior more clearly, the properties of closely related ternary systems ...
Temperature stability of the photogeneration rate in silicon thin film with back diffuse reflector
(Materials Science Forum, 2003)
The influence of temperature and other physical parameters (incident photon wavelength, Si wafer thickness, average diffuse reflectance of the back reflector) on the carrier photogeneration rate in Si thin film (less than ...
Synthesis and characterization of Cd1-xMnxS quantum dots
(Materials Science Forum, 2003)
Cd1-xMnxS quantum dots (QDs) of 4.5 nm average size with various compositions, from x = 0.001 to x = 0.15, have been synthesized by using aqueous solution precipitation. Diluted magnetic semiconductor (DMS) quantum dots ...
Influence of radiation effects on the electrical characteristics of photodetectors
(Materials Science Forum, 2003)
Radiation effects in photodetectors (photodiodes) induced by various sources and fluences were studied in this paper. The influence of irradiation was determined by forward current-voltage (I-V) measurements of electrical ...
