The aim of this study was to understand the effect high shear homogenization (HSH) and ultrasonication (US) on physicochemical properties blank olanzapine loaded nanostructured lipid carriers (NLCs) along with their drug loading potential release profiles from formulated particles. NLCs were prepared different ratios Compritol Miglyol as solid liquid lipids, respectively, under changing HSH US ...

Multicomponent reactions involving polyfunctional 4-amino-5-carboxamido-1,2,3-triazole and cyclic carbonyl-containing CH-acids were studied under conventional thermal heating, microwave and ultrasonic irradiation. The features of the reactions studied were discussed and the optimized procedures for the synthesis of final triazolopyrimidines were elaborated. In contrast to the similar MCRs of nu...

Guinea pigs, each with an established syngeneic dermal line 10 tumor and microscopic lymph node metastases, were immunized by injection of a mixture of irradiated line 10 tumor cells and an oil-in-water emulsion containing heat-killed cells of Mycobacterium bovis strain Bacillus Calmette-Guérin. Squalane or squalene-in-water emulsions, prepared by ultrasonication and containing mg doses of myco...

Gradient concentric rings of polymers, including (poly[2-methoxy-5-(2-ethylhexyloxy)-1,4-phenylenevinylene] (MEH-PPV) and poly(methyl methacrylate) (PMMA), with unprecedented regularity were formed by repeated "stick-slip" motion of the contact line in a sphere-on-flat geometry. Subsequently, polymer rings served as templates to direct the formation of concentric Au rings. Three methods were de...

We report the direct formation of multiwalled carbon nanotubes (MWNT) by ultrasonication of graphite in dimethylformamide (DMF) upon addition of ferrocene aldehyde (Fc-CHO). The tubular structures appear exclusively at the edges of graphene layers and contain Fe clusters. Fc in conjunction with benzyl aldehyde, or other Fc derivatives, does not induce formation of NT. Higher amounts of Fc-CHO a...
