Hydrogen distribution in high-purity-based polycrystalline Al-5%Mg alloys prepared by changing the melting atmosphere was visualized by means of hydrogen microprint technique with electron backscattering pattern analysis after a tensile deformation at room temperature. The number of hydrogen atoms observed as silver particles on the slip lines was increased when the applied strain was increased...

The hyperfine splitting in hydrogenlike 209Bi, 203Tl, and 205Tl is calculated with the nuclear magnetization determined from experimental data on the hyperfine splitting in the corresponding muonic atoms. The single-particle and configuration-mixing nuclear models are considered. The QED corrections are taken into account for both electronic and muonic atoms. The obtained results are compared w...
The recent report of the observation of Bose-Einstein condensation in atomic Hydrogen, characterized by an ”anomalous” density spectrum, is shown to be in agreement with the prediction of the existence of two condensates for temperatures lower than a well defined temperature (which for Hydrogen is 105 μK ), based on the QED coherent interaction in a gas of ultracold atoms at a density n > n0 (n...
Background: The aim of this study was to investigate interaction between vanillin and alpha-, beta- and gamma-cyclodextrin carriers for targeted drug delivery and compare the performance between them using theoretical methods. Methods: All theoretical calculations were performed on a Intel® Core™ i5 Processors computer at Kerman University using Gaussian 09 program package (Gaussian, Inc., Wal...

In the title Mannich base, C(20)H(21)N(3)O(3), an isatin derivative of thymol, the O-CH(2)-C(=O)-N(H)-N fragment connect-ing the aromatic and fused-ring systems is approximately planar, with the N-N single bond in a Z configuration. The amino H atom of this N-N fragment is intra-molecularly hydrogen bonded to the carbonyl O atom of the indolinone fused ring as well as to the phen-oxy O atom of ...
In the title compound, [Ir(C15H22BN6)(C8H7O)Cl]·CHCl3, the Ir atom is formally trivalent and is coordinated in a slightly distorted octa-hedral geometry by three facial N atoms, one C atom, one O atom and one Cl atom. The Ir=Ccarbene bond is strong and short and exerts a notable effect on the trans-Ir-N bond, which is about 0.10 Å longer than the two other Ir-N bonds. The chloro-form solvent mo...
