aim: to enhance the aqueous solubility of olanzapine by using the solid dispersion technique. solid dispersions of olanzapine were prepared by the dispersion method using using pgs and ssg as carriers. drug:carrier ratios such as 1:1, 1:2, 1:4, 1:6, 1:8 and 1:10 were tried for optimization. characterization was done by phase solubility, in vitro release, saturation solubility, permeation, wetta...

Near IR, multi epoch, spectroscopic and photometric observations of the enigmatic, eruptive variable V838 Mon in the JHK bands are reported. One of unusual features of the spectra is the detection of several strong neutral TiI lines in emission in the K band. From the strength of these lines, the mass of the ejected envelope is estimated to be in the range 10−7 to 10−5 M . The spectra also show...

Ultraviolet Visible Near-Infra red (UV-Vis-NIR) spectroscopy is useful to characterize the absorption, transmission, and reflectivity of a variety of technologically important materials, such as pigments, coatings, windows, and filters. This more qualitative application usually requires recording at least a portion of the spectrum for characterization of the optical or electronic properties of ...
