Abstract:
... Regenerated cellulose obtained from sugarcane bagasse was used for hydrogel preparation using epichlorohydrin (crosslinker) and green zinc oxide nanoparticles (ZNPs) which were phytosynthesised from musk melon seed extract. The synthesised ZNPs were characterised using FESEM and EDAX. The swelling capacity of the hydrogel was determined by swelling measurements. For drug delivery studies from hydr ...

Abstract:
... The present investigation deals with the latex stage functionalization of carboxylated acrylonitrile butadiene rubber (XNBR) by chemically grafting cardanol onto its backbone main chain to impart multifunctional characteristics to it. The grafting of cardanol onto XNBR in the latex stage has been accomplished successfully using benzoyl peroxide (BPO) as a free radical initiator. Cardanol grafted X ...

Abstract:
... In this study, alginate (ALG) hybrid spheres supported with magnetic halloysite nanotubes (MHNTs) were synthesized and used effectively in the removal of Pb(II) ions from aqueous solutions. MHNTs were prepared using the “co-precipitation” method. Afterward, magnetic halloysite–alginate (MHNT–ALG) hybrid beads were formed using ALG and MHNTs by the “extrusion dripping” method. The characterization ...
