Alpinetin is a flavonoidal constituent of seeds of Amomum subulatum Roxb., recently reported to possess vasorelaxant and antiHIV activities. Simple, accurate and precise HPLC and HPTLC methods were developed for the analysis of alpinetin in A. subulatum seed extracts and extraction technique was optimized to get maximum yield using conventional, ultrasonic and matrix solid phase dispersion extr...

A mathematical model is described and applied for adsorption process of ethyl acetate from supercritical CO2 stream on activated carbon particles. This model has the ability of illustrating variation of effluent concentration towards different parameters such as flow rate, temperature and pressure. In this research, a vast area of operational conditions is experienced. Mass transfer resistance ...

carbon nano-tube (cnt) reinforced metal matrix nano-composites have attracted a great deal of attention in recent years due to the outstanding physical and mechanical properties of cnts. however, utilizing cnt as reinforcement for alloy matrixes has not been studies systematically and is still a challenging issue. in the present study, cu80fe20/10cnt nanocomposite was synthesized by mechanical ...

In this study, a novel mesoporous silica nanoparticles drug carrier contributes to improving the solubility, dissolution, and the oral bioavailability of apigenin (AP). The apigenin of solid dispersion of mesoporous silica nanoparticles (AP-MSN) was prepared by physical absorption method and also, in-vitro drug release and in-vivo bioavailability performance were evaluated. Based on its solubil...
