Crystal growth and characterisation of rare earth phosphates
No full textGrowth of rare earth phosphates has been carried out from aqueous phosphoric acid solutions. The system K2O - La2O3 - P2O5 - H2O has been studied in detail within a temperature range 150 to 700 degrees C, and a series of hydrous and anhydrous phosphates have been obtained. The influence of several growth parameters like the ratio of the alkali metals to rare earth metals, the concentration of P2O5, H2O, the pH of the growth media, experimental temperature, etc. on the type and quality of the rare earth phosphate obtained has been studied. The growth mechanism of the formation of various hydrous and anhydrous phosphates in the system K2O - La2O3 - P2O5 - H2O has been studied, in order to obtain crystals with a desired morphology and quality, which helps in the in-situ fabrication of the crystals ready for use as solid state laser hosts. LaP5O14 and KLaP4O12 crystals were doped with Nd up to 20%
Effect of dehydroabietylamine in angiogenesis and GSK3-b inhibition during wound healing activity in rats.
No full textThe present research evaluates the wound healing
capacity of dehydroabietylamine, a diterpenoid isolated
from methanolic leaves extract of Carthamus tinctorius L.
(Asteraceae). The wound healing activity was screened by
excision, incision, and dead space wound models on albino
rats and for the angiogenic property using chick chorioallantoic
membrane (CAM) assay. Significant increase in
wound contraction rate, skin breaking strength, granuloma
strength, and dry granuloma weights was observed as
compared to control. The pro-healing action may be due to
increasing in collagen deposition as well better alignment
and maturation. In CAM assay, the dehydroabietylamine
showed increased angiogenic zone formation in the developing
embryos compared to normal embryos and evidenced
pro-angiogenic activity of the active constituent. Further, in
silico comparative docking of dehydroabietylamine, standard
drug nitrofurazone and positive control CHIR_98014 to
ATP-binding active pocket of glycogen synthase kinase3-b
(GSK3-b) protein that consisted of Tyr216 as a catalytic
residue, with residues Asn64, Gly65, Ser66, Phe67, Gly68,
Val70, Lys85, Leu132, Val135, Asp181, Lys183, Gln185,
Asn186, and Asp200 in the active pocket docked with dehydroabietylamine
at the torsional degree of freedom 0.5 U
with Lamarckian genetic algorithm showed the inhibition
constant of 315.6 9 10-9. But the inhibition constant of
nitrofurazone and CHIR_98014 was 34.76 9 10-6 and
4.64 9 10-6 respectively. Docking of dehydroabietylamine
to GSK3-b protein involved in Wnt signaling pathway
supported the research on wound healing property. The
above said studies explore the role of dehydroabietylamine
in wound healing activity
Measurements of breakdown voltages and V-I characteristics in selenium and tellurium vapors
No full textMeasurements of breakdown voltages and V-I characteristics were carried out, using co-axial cylindrical electrodes in Se and Te vapors in the pressure range of 6 \times to 1.131 kPa. A high temperature heat-pipe app. developed in the laboratory for detetcting the elecronic and plasma properties of metal vapors was used. The breakdown voltages in Se and Te vapors are higher than those obtained by earlier workers in Hg, Na, K, Cd and Zn vapors under similar conditions. Since the studies were carried out in metals in their vapor state, the theory of gas breakdown is considered to explain the variation in the data. The V-I characteristics are pressure dependent and do not exhibit any neg. current growth
