Steel corrosion about application of inhibitors
Abstract: In chronology of prevention of irreversible degradation of metals, inhibitors to corrosion have studied to inhibit use of toxic inhibitors. Prevention of toxic inhibitors has further studied to explore non-toxic inhibitors prepared from biological origins, e.g. plant originated or underwater organisms or expired drugs. Toxic organic inhibitors are further studied to select those in which toxicity is removed by dilution of processing chemical. If water pipelines are considered use of …

Recent Advances in Crystal Defect Engineering of Semiconductor Photocatalysts for Sustainable Environmental and Energy Applications
Abstract: Semiconductor photocatalysis has emerged as one of the most promising green technologies for addressing environmental pollution and global energy challenges through solar energy utilization. Nevertheless, the practical application of conventional semiconductor photocatalysts is often limited by their narrow visible-light absorption, rapid recombination of photogenerated electron–hole pairs, insufficient active sites, and poor charge-transfer efficiency. Defect engineering has recently attracted significant attention as an effective strategy to overcome these limitations by deliberately …

Cadmium Toxicity: Oxidative Stress and Organ Dysfunction
Abstract: Due to continued anthropogenic mobilization, cadmium accumulation in the environment causes various health problems because of its diverse toxic effects, extremely lingering biological half life (20–30 years), low rate of excretion from the body and storage predominantly in soft tissue primarily liver and kidney. Cadmium is known to have numerous noxious effects, including nephrotoxicity, hepatoxicity, osteoporosis, cardiovascular toxicity, lung toxicity, and reproductive toxicity. The biologically significant ionic form of cadmium, …

Machine-Learning-Assisted Development of Polymer-Biochar Composite Adsorbents for the Removal of Heavy Metals from Gomti River Water
Abstract: Rapid urbanization, industrial discharge, and agricultural runoff pose a significant threat to freshwater sustainability and public health. Within these ecosystems, polymer pollutants—such as microplastics, nanoplastics, synthetic fibres, and additive residues—have emerged as persistent vectors capable of adsorbing and transporting toxic heavy metals. Because these polymeric contaminants dynamically interact with conventional aquatic parameters to alter pollutant mobility and ecological risk profiles, there is an urgent need to transition from passive environmental …
