"El presente estudio de pre factibilidad se lleva a cabo en la empresa Resinpol S.A.I.C., la cual se encuentra ubicada en Capilla del Señor, Provincia de Buenos Aires, y se dedica a la producción de resinas sintéticas...

Materiais poliméricos foram propostos no desenvolvimento de novos excipientes potencialmente biodegradáveis para liberação colo-específico de fármacos. Oligossacarídeo α-gluco-oligossacarídeo (α- GOS/Bioecolian...

Os sistemas matriciais são de fácil obtenção e custo reduzido frente a outros sistemas de liberação controlada de fármacos, constituindo-se uma alternativa simples no desenvolvimento de formulações eficazes. Den...

The present study was undertaken to investigate the effect of nature of polymers like HPMC, carbopol-934P and their content levels on the release profiles of water soluble drug, diclofenac potassium. For this purpose, di...

Debido a la astringencia que manifiesta Maytenus vitis-idaea Griseb. (Celastraceae), se abordó el estudio de los taninos condensados presentes en los extractos acuosos obtenidos de hojas frescas y secas, determinándose...

The deposition of chlorhexidine base on thermosensitive N-isopropylacrylamide polymeric microparticles was assessed in this study using energy dispersive X-ray spectrometry (EDXS) in scanning electron microscopy (SEM) se...

Se ensayaron diversos polímeros de la povidona (PVP) con el objeto de determinar el tipo, técnica operativa y proporciones más adecuadas para dispersar extractos crudos vegetales en agua administrables en forma oral o...

Transdermal drug delivery systems of venlafaxine hydrochloride were prepared by using combination of hydrophilic (HPMC E15) and hydrophobic (ERS100 and ERL 100) polymers in 1:5, 2:4, 3:3, 4:2, 5:1 ratios by solvent casti...

In this critical review, metal oxides-based materials for electrochemical supercapacitor (ES) electrodes are reviewed in detail together with a brief review of carbon materials and conducting polymers. Their advantages, ...

In this new edition of their classic work on Cellular Solids, the authors have brought the book completely up to date, including new work on processing of metallic and ceramic foams and on the mechanical, electrical and ...

Examination of nature's favorite molecules reveals a striking preference for making carbon-heteroatom bonds over carbon-carbon bonds-surely no surprise given that carbon dioxide is nature's starting material and that mos...

Multilayer films of organic compounds on solid surfaces have been studied for more than 60 years because they allow fabrication of multicomposite molecular assemblies of tailored architecture. However, both the Langmuir-...

We report a method to form multifunctional polymer coatings through simple dip-coating of objects in an aqueous solution of dopamine. Inspired by the composition of adhesive proteins in mussels, we used dopamine self-pol...
