Аннотация: IIn this study, electrospinning was used to prepare ultrafine fibers from PHAs with different chemical compositions: P(3HB) and copolymers: P(3HB-co-4HB), P(3HB-co-3HV), and P(3HB-co-3HHx). The main process parameters that influence ultrafine fiber diameter and properties (polymer concentration, solution feeding rate, working distance, and applied voltage) have been investigated and their effects evaluated. The study revealed electrospinning parameters for the production of high-quality ultrafine fibers and determined which parameters should be varied to tailor the properties of the products. This study is the first to compare biological and physical-mechanical parameters of PHAs with different chemical compositions as dependent upon the fractions of monomers constituting the polymers and ultrafine fiber orientation. Mechanical strength of aligned ultrafine fibers prepared from different PHAs is higher than that of randomly oriented ones; no significant effect of ultrafine fiber orientation on surface properties has been found. None of the fibrous scaffolds produced by electrospinning from PHAs had any adverse effects on attachment, growth, and viability of NIH 3T3 mouse fibroblast cells, and all of them were found to be suitable for tissue engineering applications.

Аннотация: This paper reports on the results of investigations into the dielectric properties of liquid crystals embedded in polycapillary matrices and describes a technique for their measurement. It has been revealed that the chemical structure of the rigid core and the length of mobile alkyl groups of liquid-crystal molecules of the alkylcyanobiphenyl group substantially affect the equilibrium configuration of the liquid-crystal director in capillaries. The reorientation of liquid-crystal molecules embedded in capillaries in the nematic phase under the influence of an external magnetic field has been investigated.

Заглавие : POLARIZED LUMINESCENCE SPECTRUM OF IMPURITY LIQUID-CRYSTAL - THE DEGENERATION LIFTED AND RENEWED BY RELAXATION

Аннотация: The general molecular-statistical approach is proposed for the analysis or the polarized luminescence spectrum for impurity molecule of an arbitrary symmetry in the nematic liquid crystal matrix. On the particular example of uniaxial molecules the influence of features of the molecular electron structure, orientational statistics, molecular dynamics, and features of the anisotropic intermolecular coupling upon the positions of maxima v(if)(t) of impurity fluorescence polarized bands J(ij)(t) is studied. For the first time it is shown that all these factors significantly affect the degree of spectrum v(ij)(t) degeneration. For t not-equal 0, relaxation of excited impurity molecule subsystem toward the orientational distribution lifts a partial degeneration of spectrum v(ij), occuring at t not-equal 0, and renews partial or total degeneration of spectrum v(ij) in the limit t = infinity. In the lack of the spectrum v(ij) degeneration for t = 0 the relaxation may restore partial degeneration for t not-equal 0 as a function of the features of electron structure of molecules. The results of work explain the familiar experimental data on the number of independent component v(ij) and relation between them, on dependence of v(ij) upon the order of matrix and impurity subsystem, on the mutual relation in the positions of impurity band polarized component in the absorption and fluorescence spectra.
