Preparation of Bi2Se3 quantum dots by dissolution of crystalline powder in acetonitrile
(Journal of Materials Science Letters, 1998)
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 ...
Production of fragments with Z GT = 8 in interaction of 12.7 GeV He-4+U, Pb, Au and Ag: track detector study
(European Physical Journal A. Hadrons and Nuclei, 1998)
The processes of production of fragments with Z greater than or equal to 8 in the interaction of 12.7 GeV He-4 with U, Pb, Au and Ag have been analyzed using the polycarbonate track detector Makrofol. The sandwich technique ...
Human extracellular proteins display a different pattern of local sequence similarity with the four classes of human T-cell receptor V regions than foreign proteins and human intracellular proteins: a preliminary report
(Immunology Letters, 1998)
A pool of 110 randomly selected/generated amino acids sequences was used to perform specific local sequence similarity alignment analysis with the pool of 279 reported sequences of human T-cell receptor (TCR) V-regions. ...
The sorption characteristics and thermal stability of epoxy coatings electrodeposited on steel and steel electrochemically modified by Fe-P alloys
(Progress in Organic Coatings, 1998)
The corrosion behaviour and thermal stability of epoxy coatings electrodeposited on steel and steel electrochemically modified by Fe-P alloys of different phase structures have been investigated during exposure to 3% NaCl. ...
Full-potential linear-muffin-tin orbital atomic-sphere approximation calculations of the electric field gradient in HCP metals
(Physica B: Condensed Matter, 1998)
In this paper we suggest a new scheme for obtaining electronic contribution to the electric field gradient (EFG) at the nucleus. The EFG for ali HCP metals from Be to Cd is obtained from band structure calculations using ...
Vibrational structure of the B-X system of isotopic AgO molecules
(Spectroscopy Letters, 1999)
Spectra of (AgO)-Ag-107-O-18 and (AgO)-Ag-107-O-16 molecules have been obtained in a low-pressure are in oxygen atmosphere, and recorded with medium dispersion. Vibrational assignments for the bands of B(2)Pi-X(2)Pi system ...
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 ...
Phase composition and fracture toughness of Si3N4-ZrO2 with CeO2 additions
(Ceramics International, 1999)
Zirconia toughened Si3N4 was prepared with addition of CeO2 by applying hot pressing technique. Phase composition, densification, fracture toughness and hardness were investigated as a function of hot pressing temperature ...
Transition metal complexes with thiosemicarbazide-based ligands. 33. [4-(2-diphenylphosphino-alpha-ethoxybenzyl-P)-3-methyl-1-salicylidene-isothiosemicarbazido-N-1,N-4,O]nickel(II)
(Acta Crystallographica. Section C: Crystal Structure Communications, 1998)
The title compound, [Ni(C30H28N3O2PS)], is the first example of a transition metal complex involving a thiosemicarbazide-based tetradentate ligand with a P atom in its coordination sphere. The Ni atom in the complex has a ...
