Natural and synthetic pesticide and their effect on life
Abstract: Natural and synthetic pesticides both play roles in pest control but differ significantly in their impact on life and the environment. Natural pesticides, often derived from plants and microorganisms, are biodegradable, eco-friendly, and generally exhibit lower toxicity to non-target organisms and humans. Synthetic pesticides, while highly effective in pest control and used extensively in conventional agriculture, tend to have greater toxicity, persist longer in the environment, and pose more significant …

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). …

Hydrogenated Nitrile Butadiene Rubber (HNBR): A Comprehensive Review
Abstract: HNBR is produced by the hydrogenation of nitrile rubber (NBR) using either a homogeneous or heterogeneous technique. NBR is a copolymer of butadiene and acrylonitrile monomers. The hydrogenation process involves adding hydrogen to the nitrile butadiene copolymer, which results in improved resistance to heat, oxidation, and chemicals compared to NBR. This process alters the molecular structure of the rubber, providing it with superior properties compared to its unmodified counterpart, NBR. …
