Phase Transitions and Nonlinear Optical Property Modifications in BaGaSe.

Phase transitions can change the crystal structure and modify the physical properties of crystals. In this work, we investigate the phase transition behavior in BaGaSe, an important middle infrared (mid-IR) nonlinear optical (NLO) crystal, in the temperature range from room temperature to 1173 K. Interestingly, the BaGaSe crystal undergoes a reversible ferroelastic phase transition at = 528 K, resulting in the presence of a newly discovered phase (γ-phase) at the higher temperature.

Thermophysical properties of lithium thiogallate that are important for optical applications.

Lithium thiogallate LiGaS is one of the most common nonlinear crystals for mid-IR due to its extreme beam strength and wide transparency range; however, its thermophysical properties have not yet been practically studied. Large crystals of high optical quality are grown. DTA revealed features at 1224 K below melting point (1304 K) that are associated with the oxygen containing compounds of the LiGaO S type.

Computer Simulations of Deep Eutectic Solvents: Challenges, Solutions, and Perspectives.

Deep eutectic solvents (DESs) are one of the most rapidly evolving types of solvents, appearing in a broad range of applications, such as nanotechnology, electrochemistry, biomass transformation, pharmaceuticals, membrane technology, biocomposite development, modern 3D-printing, and many others. The range of their applicability continues to expand, which demands the development of new DESs with improved properties. To do so requires an understanding of the fundamental relationship between the structure and properties of DESs.

Branched linear lactide chains for cellulose nanoparticle modification: an atomistic molecular dynamics study.

We studied the structure of brushes consisting of branched oligolactide (OLA) chains grafted onto the surface of cellulose nanoparticles (CNPs) in polylactide (PLA) and compared the outcomes to the case of grafting linear OLA chains using atomistic molecular dynamics simulations. The systems were considered in a melt state. The branched model OLA chains comprised one branching point and three branches, while the linear OLA chains examined had a molecular weight similar to the branched chains.

Grafting-Induced Structural Ordering of Lactide Chains.

The structure of a grafted layer of lactide chains in the "dry brush" regime immersed in a melt of chemically similar polymer was examined while varying graft lengths. To this end, microsecond atomistic molecular dynamics simulations were performed. Almost no influence of graft length on the fraction of the grafted chains backfolded to the grafting surface was found.

Sequence of phase transitions in (NH)SiF.

Single crystals of silicon double salt (NH)SiF = (NH)SiF·NHF = (NH)[SiF]F were grown and studied by the methods of polarization optics, X-ray diffraction and calorimetry. A sequence of symmetry transformations with the temperature change was established: P4/mbm (Z = 2) (G) ↔ Pbam (Z = 4) (G) ↔ P2/c (Z = 4) (G) ↔ P1[combining macron] (Z = 4) (G) ↔ P2/c (Z = 8) (G). Crystal structures of different phases were determined.

A non-typical sequence of phase transitions in (NH4)3GeF7: optical and structural characterization.

Single crystals of germanium double salt (NH4)3GeF7 = (NH4)2GeF6·NH4F = (NH4)3[GeF6]F were grown and studied by the methods of polarization optics and X-ray diffraction. The birefringence Δn = (no - ne), the rotation angle of the optical indicatrix ϕ(T) and unit cell parameters were measured in the temperature range 100-400 K. Three structural phase transitions were found at the temperatures: T1↓ = 279.

Facilitation of acetylcholine secretion in mouse motor synapses caused by calcium release from depots upon activation of L-type calcium channels.

Pharmacological disinhibition of L-type Ca(2+) channels by two ways (with agonist S(-) BAY K 8644 and iberiotoxin, a Ca(2+)-activated BK-type K(+)-channel blocker) increases quantal content of evoked end-plate potentials, which was completely prevented by ryanodine (2 microM) blockade of ryanodine receptors. We conclude that increased quantal secretion of the transmitter induced by L-type Ca(2+) channel functioning requires activation of ryanodine receptors and calcium release from depots in motor terminals in mice.

[Single-stage detection of A and B antigens in the hair by absorption-elution and mixed agglutination techniques].

The proposed method is intended for single-stage detection of A and B antigens in ultrafine hair fragments by means of absorption-elution and mixed agglutination techniques with the use of a mixture of anti-A and anti-B sera.

Orthorhombic aluminium oxyfluoride, AlOF.

Crystals of the title compound were extracted from the bulk of grown SrAlF(5) crystals as unexpected inclusions that were identified as the long sought after aluminium oxyfluoride. The structure of AlOF is built up from tetrahedral and octahedral polyhedra. Each tetrahedron is bisected by a mirror plane, with the Al atom and two vertex anions in the plane.

[The prognosis of liver failure in patients with liver cirrhosis under surgical treatment for portal hypertension].

On the basis of studying the intraoperative biopsy specimens in 44 patients with hepatic cirrhosis and portal hypertension syndrome, who had a distal splenorenal anastomosis been created, the authors have distinguished three types of morphological changes--A, B, C. A significant dependence between the type of cirrhosis and pronouncement of hepatic failure after the operation and life-time of a patient after the operation as well has been established. Type C has the greatest risk, type B requires differential approach, type A is prognostically favourable concerning both the outcome of the operation and life-time of a patient.

[Reaction of the salivary glands to acute stress].

Experiment on male rats has shown that acute stress suppressed amylase and superoxide dismutase activity in the submandibular salivary glands. The influence of short repeated stresses weakened the inhibiting effect of the acute stress on the activity of enzymes. A conclusion is drawn about the high sensibility of salivary glands to stress influences.

[Results of coded trials of the activity of the trivalent subunit influenza vaccine Grippovak in Moscow kindergartens in December 1983 through the 1st quarter of 1984].

During the autumn-winter epidemic of influenza-like diseases in December, 1983--first quarter, 1984, in Moscow commissioned coded observations on the effectiveness of prophylactic vaccination against influenza of 3-7-year-old children with a preparation "Grippovak SE-AZh" were carried out in day-care centers. In the previous large-scale trials, 1981-1984, the "Grippovak" had been evaluated positively as a completely harmless, serologically and immunologically active preparation reducing 3-3.5-fold the number of laboratory-verified cases of viral type A and B influenza in the vaccinees.

[Immunogenicity and the protective effectiveness of the subunit trivalent influenza vaccine Grippovac].

In the process of the immunological approbation of several experimental batches of the triyalent subunit influenza vaccine Grippovac, the pronounced immunogenicity of the antigens of all strains contained in the vaccine was established; most of the vaccinees were found to retain sufficiently high antibody titers for a year, and the essential total increase of antibody titers was found to occur after a single booster immunization. The serological checking of the diagnosed cases of influenza among immunized and nonimmunized children, carried out in two boarding schools during the influenza epidemic in the winter of 1984-1985 provided the proofs of the high effectiveness of Grippovac in preventing viral influenza, types A and B: the decrease of influenza morbidity among the immunized children reached 79,5-67,2-66,5% and the total morbidity rate in influenza in these two boarding scholls dropped, on the average, 3,0-3,5 times.

Subunit influenza virus vaccine Grippovac SE-AZh (vaccination of adults).

Grippovac SE-AZh a polytype, subunit influenza virus vaccine containing H1N1 and H3N2 influenza A virus strains and one influenza B virus strain has been tested in 80 volunteers. The trials demonstrated the harmlessness, the absence of adverse reactions, and except of the B type, the high antigenicity of vaccine preparation when administered in two injections. The optimal dose of each viral strain haemagglutinin (HA) was 15 micrograms in 0.
