Preparation of Bi2Se3 quantum dots by dissolution of crystalline powder in acetonitrile
(Journal of Materials Science Letters, 1998)
The role of solitons in charge and energy transfer in 1D molecular chains
(Physica. D: Nonlinear Phenomena, 1998)
The idea that polarons and solitons could play the crucial role in the transport processes in biological structures, has been critically reexamined on the basis of the general theory of self-trapping phenomena. The criteria ...
Modified pyrophosphate-Tc-99m kit for application in nuclear cardiology
(Journal of Radioanalytical and Nuclear Chemistry, 1998)
A modified Tc-99m(Sn)-pyrophosphate (PyP) kit for the application in nuclear cardiology (radioventriculography, angiocardiography, scintigraphy of blood pool) was developed. Each vial contains 12 mg PyP (Na4P2O7), 4 mg ...
Classification and existence of polarons and solitons in molecular chains: Phase diagram
(Solid State Phenomena, 1998)
The problem of the existence and stability of various types of self-trapped (ST) states (polarons) in 1-d molecular systems has been analysed within the framework of the general theory of self-trapping phenomena. An ...
Mechanochemical synthesis of PbTiO3 from PbO and TiO2
(Journal of Alloys and Compounds, 1998)
Data on mechanochemical synthesis of PbTiO3 from PbO and TiO2 without subsequent heating of activated mixtures are presented. Physical and chemical processes occurring during mechanical activation are followed by the X-ray ...
Optimization of nonlinear optical rectification in parabolic quantum wells using supersymmetric quantum mechanics
(Solid State Phenomena, 1998)
A systematic procedure is proposed for the optimized design of semiconductor quantum well structures that provide maximal values of the resonant optical rectification coefficient. It relies on employing supersymmetric ...
Exact solution of the Ising model on checkerboard fractals in an external magnetic field
(Physical Review E, 1998)
In this paper we use a diagrammatic technique to determine the exact recursion relations for the partition function of the Ising model in an external magnetic field, situated on the first two members of the checkerboard ...
Simulations of anomalous stimulated Raman backscattering in a bounded plasma
(Journal of the Physical Society of Japan, 1998)
Temporal pulsations, bursting and incoherence of stimulated Raman backscatter in a bounded, underdense plasma were observed in relativistic particle-in-cell simulations. We show that backscatter complexities, modulated and ...
Quantum well shape tailoring via inverse spectral theory: Optimization of nonlinear optical rectification
(Physics Letters A, 1998)
A procedure for the design of quantum well structures optimized in respect to the intersubband resonant optical rectification generation is proposed. It relies on the inverse spectral theory, allowing one to generate a ...
Reaction cross sections in Si of light proton-halo candidates N-12 and Ne-17
(Nuclear Physics A, 1998)
Total reaction cross sections, sigma(R), on Si were measured near 40 A MeV for the proton-halo candidate N-12 and the two-proton-halo candidate Ne-17, and were compared with sigma(R) for other light proton-rich nuclei. The ...
