A series of high-density polyethylene/Cloisite 20A/graphite nanocomposites were prepared via melt blending for the production of polymeric pipes for natural gas transfer. The microstructural, mechanical, thermal, electrical and barrier properties of prepared nanocomposites were investigated. An intercalated morphology was observed for prepared nanocomposites. Improved mechanical properties ...

In this research, polypropylene fibers and nonwoven samples were produced with the commercial samples of nanoclay additives in semi-commercial processing machinery. Influence of two different types of nanoclay additives, at different add on levels on processing, structure and morphology of nonwovens is studied. The WAXD and DSC data showed some change in crystallinity and melting behavior indic...

Sciortino, Christopher M., and Michael F. Romero. Cation and voltage dependence of rat kidney electrogenic Na-HCO3 2 cotransporter, rkNBC, expressed in oocytes. Am. J. Physiol. 277 (Renal Physiol. 46): F611–F623, 1999.— Recently, we reported the cloning and expression of the rat renal electrogenic Na-HCO3 2 cotransporter (rkNBC) in Xenopus oocytes [M. F. Romero, P. Fong, U. V. Berger, M. A. Hed...

We have systematically investigated the phase diagram of clay particles in water to understand the relation between the local and macroscopic properties and the structures of clay suspensions. We focused, in particular, on sodium Cloisite (CNa) particles at concentrations typically used in nanocomposites (concentrations from 1 to 4 wt %) and at an extended range of ionic strengths (10(-5) to 10...

dermoid cyst is a tumor arises due to embryogenesis impairment. it accounts for less than 0.3 percent of all intracranial masses. a 35 years old man presented with a tonic clonic seizure without any significant past history of seizure. physical examination and imaging propounded epidermoid cyst as diagnosis. the patient had a craniotomy and cyst was totally removed. operative findings and histo...

Abstract The present study introduces an overview of gentamicin-clay mineral systems for applications in biomedicine and then focuses on the development a series gentamicin/clay hybrid materials to be used as bioactive phase hydroxypropylmethylcellulose (HPMC) produce bionanocomposite membranes possessing antimicrobial activity interest wound-dressing applications. Gentamicin (Gt) was adsorbed ...
