The photoluminescence and excitation spectra of natural olivines from dunites and harzburgites in Ural Alpine-type hyperbasites have been examined. Emission bands have been observed from SiO4 3- centers (420, 440, and 470 ...
The correlated effective field approach, proposed by Lines, for computing the magnetic ordering temperature of a ferromagnet with single-ion anisotropy, is generalized for the case of a collinear uniaxial antiferromagnet. ...
The strongly correlated system HoB1211 with boron sublattice Jahn-Teller instability and nanoscale electronic phase separation (dynamic charge stripes) was studied in detail by inelastic neutron scattering (INS), magnetometry, ...
We have constructed the crystalline electric field (CEF) splitting of the energy levels of Yb3+ (4f13) in the clean intermetallic compounds YbRh2Si2 and YbIr2Si2. The data of measurements using methods of inelastic neutron ...
After isothermal crystallization of the crystallizable poly(ethylene oxide)/amorphous poly(propylene oxide) mixture, partially crystalline structures were formed. They present a specific heterogeneous medium with a hard ...
The use of the amorphous forms of drugs is a modern approach for the enhancement of bioavailability. At the same time, the high cooling rate needed to obtain the metastable amorphous state often prevents its investigation ...
Fast scanning calorimetry (FSC) is used to study crystallization of poly(vinylidene fluoride) (PVDF), and its blends with a random fluorinated copolymer (FCP) of poly(methyl methacrylate) and 1H,1H,2H,2H-perfluorodecyl ...
The kinetics of crystallization of oligo(ethylene glycol) in the presence of carbon tetrachloride, have been studied by the pulsed NMR method. It was found that the overall rate of crystallization and the shape of the ...

The kinetics of isothermal crystallization of poly(ethylene oxide) confined in pores of active carbon was studied by nuclear magnetic resonance relaxation. At equal temperatures the induction period of crystallization in ...
Crystallization of three 4-arylsulfonyl-2(5H)-furanones from chloroform leads to the formation of a conglomerate of sulfone with para-tolyl substituent and racemic crystals of chloro and bromo analogs. The high degree of ...
For the last fifty years, X-ray crystallography and allied methods have been one of the most important analytical techniques for chemical analysis. With improved equipment, computers, and programs, the time required for ...
We introduce a notion of CS-Rickart module being a modular analog of the ACS-ring concept. We describe the rings over which each finitely generated projective module is CS-Rickart module. The presented results yield the ...
