the purpose of this study was to investigate the effect of additives, poly(ethylene glycol) (peg) 1450, poloxamer 407, polyvinyl alcohol (pva) and sodium chloride in order to improve physico-chemical characteristics, encapsulation efficiency and in vitro release of bovine serum albumin, form poly(d,l-lactic-co-glycolic acid) (plga) microparticles prepared by the w/o/w solvent evaporation method...

In recent years, the demand for tantalum capacitors has been increasing due to miniaturization of electronic devices. Tantalum capacitors, which use rare metal as capacitor element, are used in devices such cell phones because they smaller and have a higher capacity than conventional capacitors. Japan, there reports that minerals containing elements being extracted from discarded electrical equ...

Crystallization in the presence of additives like surfactants and polymers is a relatively less explored area but is important for polymorphic screening of a compound during its developmental stage. Surfactants and polymers act by various mechanisms to influence either the growth or the nucleation phase, resulting in modification of either the polymorphic form or the crystal habit. The present ...
