Thermal properties of Nichrome 5 - a contribution to the understanding of kinetics of structural transitions
(High Temperatures: High Pressures, 2003)
A study is presented of the structural transition in the Nichrome 5 alloy (80Ni-20Cr), more precisely of its dependence on the heating rate. The phenomenon was observed in the study reported at the 12th ECTP in Vienna, ...
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 ...
Surface properties of HAP particles obtained by hydrothermal decomposition of urea and calcium-EDTA chelates
(Key Engineering Materials, 2003)
In this paper surface properties of calcium-hydroxyapatite, synthesized by modified hydrothermal reaction of urea and Ca(EDTA)(2-) in phosphate solutions, as well as the dependence of calcium hydroxyapatite dispersion ...
An operator for simultaneous unsharp measurement of coordinate and momentum
(Fortschritte der Physik = Progress of Physics, 2003)
Starting from a complete but not overcomplete set of coherent states defined on a lattice in the phase space, we construct the orthonormal basis using the procedure due to Lodwin, in which all states to be normalized enter ...
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 ...
On stimulated scattering of laser light in inertial fusion energy targets
(Fusion Science and Technology, 2003)
Propagation of a laser light through regions of an underdense plasma is an active research topic in laser fusion. In particular, a large effort has been invested in studies of stimulated Raman scattering (SRS) and stimulated ...
Vibrational analysis of the beta system of (BO)-B-10-O-18
(Spectroscopy Letters, 2003)
Ten bands of the system (B(2)Sigma(+)- X(2)Sigma(+)) of the (BO)-B-10-O-18 molecule have been observed for the first time. The spectrum was obtained by emission spectroscopy from a low-pressure arc, at medium dispersion, ...
Sorption of selenium anionic species on apatites and iron oxides from aqueous solutions
(Journal of Environmental Radioactivity, 2003)
The sorption of selenite and selenate ions from aqueous solutions was investigated on hydroxyapatite, fluorapatite, goethite and hematite, in order to simulate the behavior of radioactive selenium in natural or artificial ...
