Thermoplastic elastomers (TPEs), based in PP (Polypropylene) / EPDM (Ethylene Propylene Diene Monomer) have as purpose improving resistance and impact, aiming to a more comprehensive use automotive market, among edifications, construction packaging sectors, due their recyclability properties. is commodity, with high melting point, mechanical low density, posing balance between physical properti...

The deficiency of water sources and the environmental disposal large amounts biomass waste (orange peels) produces economic problems, though its conversion into biochar by a pyrolysis procedure might be used to improve soil productivity. In current study, we investigated performance superabsorbent composite grafted on CMC as low-cost, alternative, biodegradable terpolymer (IPNCB) for retention ...

Polymers based on 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) attract significant attention due to their large water absorption capacity when swollen in water. Poly(AMPS) (PAMPS) hydrogels are usually synthesized via free-radical cross-linking copolymerization of AMPS and a chemical cross-linker aqueous solutions. Owing the covalently cross-linked network structure PAMPS preventing diss...

Different types of lamellar-within-lamellar structure formations in A-b-(B-b-A)(n)-b-C terpolymer melts, with a volume fraction of components A, B, and C in the ratio of 1:1:2, are analyzed in the strong segregation limit using a simple theoretical approach. We consider the lamellar, parallel lamellar-within-lamellar, and perpendicular lamellar-within-lamellar self-assembled states. The influen...

Many studies in recent years have focused on surface engineering of implant materials in order to improve their biocompatibility and other performance. Porous tantalum implants have increasingly been used in implant surgeries, due to their biocompatibility, physical stability, and good mechanical strength. In this study we functionalized the porous tantalum implant for sustained drug delivery c...
