Enhanced photocorrosion stability of colloidal cadmium sulphide-silica nanocomposites
(Journal of Materials Science Letters, 1999)
Room-temperature luminescence of AgBr quantum dots
(Chemical Physics Letters, 1999)
A new method for the preparation of 25 Angstrom AgBr quantum dots has been developed. The room-temperature emission of size-restricted AgBr crystallites was observed. The emission spectrum of 25 Angstrom AgBr quantum dots ...
Numerical simulation of photothermal effects in solids with inhomogeneous thermal properties
(Journal of Physics. D: Applied Physics, 1999)
A numerical simulation procedure for the calculation of surface temperature in thermally inhomogeneous solids induced by a harmonically modulated external heat source is presented. The procedure is based on the separation ...
Some optical properties of the spiral inflector
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 1999)
This paper compares some optical properties of different spiral inflectors using the program CASINO. The electric field distribution in the inflectors has been numerically calculated from an electric potential map produced ...
Prevention and recovery of CuSO4-induced inhibition of Na+/K+-ATPase and Mg2+-ATPase in rat brain synaptosomes by EDTA
(Toxicology Letters, 1999)
Enzymatic activities of Na+/K+-ATPase and Mg2+-ATPase from rat brain synaptic plasma membrane were studied in the absence and presence of EDTA. The aim of the study was to examine the ability of this strong chelator to ...
Some observations on mechanical activation of the CeO2-ZrO2-SiO2 system
(Journal of Alloys and Compounds, 1999)
Mechanical activation of CeO2-ZrO2-SiO2 mixtures was performed in a high energetic vibratory mill with WC lining and grinding media. It was shown that in air atmosphere the reduction of Ce4+ into Ce3+ took place at 1400 ...
Surface properties of metal ions modified silicas
(Colloids and Surfaces. A: Physicochemical and Engineering Aspects, 1999)
The surface properties of metal (alkali and alkaline earth) modified silica beads were investigated by the inverse gas chromatography method. Silica beads, obtained from silica sol, were characterized by their specific ...
Fully relativistic description of extraordinary and quasilongitudinal waves propagating in plasmas
(Plasma Physics and Controlled Fusion, 1999)
Extraordinary and quasilongitudinal waves propagating at an arbitrary angle with respect to the steady magnetic field are investigated within the fully relativistic theory. The results of the present paper complement the ...
Prefission neutron multiplicities and the fission modes of Th-226
(Europhysics Letters / EPL, 1999)
The neutron spectra associated to the two fission modes of Th-226 have been measured in coincidence with the fragment yields of the O-18 + Pb-208 reaction at E-lab = 78 MeV. The pre- and post-fission multiplicities and ...
Tc-99(m)-p-aminohippuric acid as a new renal agent
(Nuclear Medicine Communications, 1999)
Tc-99(m)-p-aminohippuric acid (Tc-99(m)-PAH) is a new renal radiopharmaceutical prepared from a lyophilized kit by the addition of sodium pertechnetate ((NaTcO4)-Tc-99-O-m. Each vial contains PAH, the calcium trisodium ...
