Skin drug delivery systems with controlled release are suitable means for the local transfer of pharmaceutical compounds to the damaged and healthy layers of skin. Nanofibrous membrane prepares uniform moisture in the wound environment with less accumulation of fluid secretion due to its variable pore size. Electrospinning takes advantage of using herbal extracts in the form of electrospun nano...

recently, the use of biological absorbent in removal of hazardous pollutants such as heavy metals has increased because of the decrease in sludge problems, economical issues, high efficiency and compatibility with the environment. this study was done over the biosorption of nickel by biosolids obtained from the municipal wastewater treatment in a batch reactor. the pretreatment of the biosolids...

Sunscreens have become a product based on increasingly complex formulations that include, among many ingredients, mixture of UV filters to provide optimal sun ultraviolet radiation protection. A significant group scientific works deals with the impact in aquatic media. However, knowledge mechanism and kinetics compound’s direct release, fate, its transformation interaction living organisms is n...
