Investigation of Groundwater Contamination Due to Heavy Metals for Sustainable Development of Agriculture in Punjab State, India
Abstract: Punjab, an intensive agricultural state, is currently experiencing a problem because of elevated levels of heavy metals and uranium (U) in its groundwater. It is commonly known that the groundwater in every district in Punjab's Malwa region has anomalous levels of uranium, with a U content that exceeds the World Health Organization (WHO) safe limit of 30 parts per billion. There have been reports of arsenic (As) in the Majha …

A comprehensive study on elemental analysis and sustainable integration of CETP (common effluent treatment plant) sludge as a substitute to sand in concrete
Abstract: This study examines the utilization of sludge from common effluent treatment plants (CETP) as a fractional substitute for sand in M20 concrete mixtures. Its aim is to address disposal challenges associated with CETP sludge while promoting sustainable use of natural resources. The research assesses the structural and microstructural attributes of concrete mixes containing varying percentages of CETP sludge (0%, 10%, 20%, 30%, 40%, and 50%). Tests conducted include compressive, flexural, …

Experimental Investigation of Aluminum Alloy 8010 by Friction Stir Welding
Abstract: A solid state welding method called friction stir welding (FSW) is used to fuse metals and alloys that are challenging to fuse using traditional fusion welding. The effects of tool pin and shoulder diameter on joining the aluminum alloy Al 8010 were examined in this study. The basis material for combining single butt-welded joints is a plate with a thickness of 6 mm. The welding was carried out on the …

The Effects of Physiochemical Parameters and Microbial Counts on Metal Coupons Corrosions in Freshwater Environment at Different Water Depths
Abstract: The effect of water quality on metal coupon corrosion was investigated at the New Calabar River in Choba. The study examined metal corrosion rates at five different depths: 30 cm, 60 cm, 90 cm, 120 cm, and 150 cm in a freshwater environment. Water samples were collected at each depth and analyzed for physicochemical and microbial parameters to understand their impact on metal degradation. Key parameters measured included pH, Electrical …

Green Fabrication of Glutaraldehyde-Crosslinked Chitosan/PVA Biocomposite for Heavy Metal Removal from Wastewater
Abstract: Chitosan (CS) and Polyvinyl alcohol (PVA) are polymers that possess biodegradable, biocompatible, and non-toxic properties, making them suitable for wastewater treatment applications. The primary objective of this research is to chemically modify chitosan in a novel manner to enhance its ability to remove hexavalent chromium Cr(VI) from aqueous solutions. In this study, a composite material was synthesized by crosslinking PVA and CS with glutaraldehyde (GA), resulting in the formation of …
