There are specific areas where the nanoparticles administration may have an advantage over microparticles based on drug delivery system. One area that has been of great interest is the use of the biodegradable polymer nanoparticles as PLGA or some modification on its surface for delivery of anti-cancer agents and other therapeutic agents. The understanding of…
DetailsA patent is the right to ownership where by a person / organization discovers a lesser known concept or invents something new and holds sole intellectual ownership rights to that particular idea. These are usually published / granted after a lot of research and exhaustive verification. Pharmaceutical patents protect manufacturers of prescription drugs, prohibiting others…
DetailsChemical companies large and small are eager to become greener. They want to be able to select greener starting materials and use cleaner chemical processes to make environmentally preferred products. But there are no authoritative marketplace criteria to identify green, greener, or greenest. And for those who think they are green, there’s uncertainty over the…
DetailsRock S.O.S. (Stars Of Science) [1] es una campaña de promoción de la investigación medica, diseñada por la compañía del diseñador Geoffrey Been (fallecido en 2008 por Cáncer), en donde buscan concienciar al ciudadano común y corriendo que cada avance en el campo de la investigación en aplicaciones biomedicas representa una mejora en la calidad de vida de todos, por lo que se busca que la gente entienda la…
DetailsNo se cuantos de nosotros estamos siguiendo el derrame del golfo de Mexico, pero aqui les “posteo” varios articulos interesantes de la pagina livescience.com. Anatomy of the Gulf Oil Spill Here’s a look under the hood at how officials, and their robots, are trying to stem the flow of oil leaking from the well beneath the…
DetailsReview the x-ray technique in the ” In-situ X-ray Absorption Spectroscopy of Supported Ru Catalysts in the aqueous phases’ Many of the techniques used to characterize catalysts in the presence of vapor-phase molecules are not appropriate for liquid water. Because X-ray absorption spectroscopy and H2 chemisorption are specific probes of the active transition metal, we…
DetailsIn recent years there is an increasing interest in developing new approaches to improve the efficiency of photovoltaic cells (solar cells). Silicon is the most widely used material for solar cells and is due to its abundance in nature, stability, non-toxicity and well established refining and processing technologies [1]. Even though commercial single crystalline silicon solar…
DetailsNematic liquid crystalline polymers (LCP’s) are interesting anisotropic fluids, which may have some orientational order at rest (molecules tend to align in the same direction). Those polymers may be useful to obtain oriented materials with excellent mechanical, electrical and thermal properties. Its rheological, mechanical and optical properties may be changed by the particle inclusion, depending…
