Effect of Polymer Crosslinking on Drug Release Kinetics
Abstract: In order to improve treatment effectiveness and minimise adverse effects, polymer-based drug delivery systems are often used to produce regulated and sustained drug release. Polymer crosslinking, which alters the structural, mechanical, and degrading characteristics of the polymer matrix, is one of the key elements affecting drug release kinetics. The porosity, swelling behaviour, and rate of degradation of the polymer are all impacted by the crosslinking process, which may be accomplished …

Experimental Study on the Impact of Polymer (PAM) in Enhancing Oil Recovery in Upper Assam Basin Oil fields
Abstract: The Upper Assam Basin, one of India’s most mature and extensively exploited hydrocarbon provinces, is experiencing declining oil production due to reservoir depletion and unfavorable crude oil–brine–rock (COBR) interactions. In this context, alkali–polymer (AP) flooding has emerged as a promising chemical enhanced oil recovery (EOR) strategy. AP flooding reduces interfacial tension (IFT) through in-situ surfactant generation by alkali and improves sweep efficiency via polymer-based mobility control, typically using polyacrylamide (PAM). …
