a etilcelulosa (EC) ha sido ampliamente usada como material adecuado en el desarrollo de nuevos sistemas para liberación modificada de fármacos. Algunos oligo-polisacáridos como inulina (IN), goma guar(GG) y sus deriv...

The viability of employing flow analysis coupled to Fourier transform infrared spectroscopy (FA-FTIR) as a useful tool for quantitative measuring of magnesium sulphate in pharmaceuticals was explored, developed and valid...

Optical detection and spectroscopy of single molecules and single nanoparticles have been achieved at room temperature with the use of surface-enhanced Raman scattering. Individual silver colloidal nanoparticles were scr...

To use solar irradiation or interior lighting efficiently, we sought a photocatalyst with high reactivity under visible light. Films and powders of TiO(2-x)N(x) have revealed an improvement over titanium dioxide (TiO2) u...

Two methods for simultaneous estimation of acetaminophen, chlorpheniramine maleate and caffeine in pure and tablet dosage form have been developed. Method I employs formation and solving of simultaneous equation using ...

The influence of the nonionic surfactant lauryl alcohol ethoxylate with 12 moles ethylene oxide (LAE-12OE) was evaluated on the Stratum corneum model biomembrane (SCMM) of shed snake skin (Bothrops jararaca and Spilotes ...
