Metal speciation studies are of great importance in assessing metal bioavailability aquatic environments. Functionalized membranes a simple tool to perform chemical speciation. In this study, we have prepared and tested polymer inclusion membrane (PIM) made the cellulose triacetate (CTA), extractant di-(2-ethylhexyl) phosphoric acid (D2EHPA), plasticizer 2-nitrophenyloctyl ether (NPOE) as senso...

We introduce a new disorder regime for directed polymers in dimension 1 + 1 that sits between the weak and strong disorder regimes. We call it the intermediate disorder regime. It is accessed by scaling the inverse temperature parameter β to zero as the polymer length n tends to infinity. The natural choice of scaling is βn := βn−1/4. We show that the polymer measure under this scaling has prev...

Tissue engineering has shown great promise for creating biological alternatives for implants. In this approach, scaffolding plays a pivotal role. Hydroxyapatite mimics the natural bone mineral and has shown good bone-bonding properties. This paper describes the preparation and morphologies of three-dimensional porous composites from poly(L-lactic acid) (PLLA) or poly(D,L-lactic acid-co-glycolic...

Present days natural fibers have transformed the matter of research field among various fields study to inculcate it in manufacture composites instead production using areca and sisal polymer-based composite. This is due respective advantages related like eco-friendly, low cost, convenience copiousness, biodegradability. Stacks work been carried out fiber-reinforced polymer composites, composit...
