Ru(III)-Catalyzed Oxidative Cleavage of Ritodrine Hydrochloride: A Kinetic and Mechanistic Study
Abstract: A systematic kinetic and mechanistic study of the oxidation of ritodrine hydrochloride (RTH) with chloramine-T (CAT) in both HClO4 and NaOH media has been carried out at 303 K. In acid medium, the reaction rate is very sluggish to be measured kinetically. Ruthenium (III) chloride ([Ru(III)]) was found to be an efficient catalyst. The reaction rate exhibits a first-order dependence on [CAT]0 in both media. It shows a fractional-order on …

Corrosion inhibitors of steel applicable by green but toxics
Abstract: Inhibitors in detergent and alkali based chemicals are used in various media for steels. Toxicity has induced pharmaceutical compounds as better inhibitors to restrict pollutant gases emissions after reaction with alkaline inhibitors. Green in origin inhibitors are toxin free to use with detergents for inhibition of both pollutant gases and corrosion of processing machineries made of metals. Eco-friendly inhibitors have appeared for steel corrosion being embedded in concrete i.e. alkaline …

Polypropylene Fibres in Cementitious Composites: A Critical Review of Polymer Structure, Processing, Interfacial Behaviour and Performance
Abstract: Polypropylene (PP) fibres are widely used as secondary reinforcement in cementitious composites, yet their performance is governed as much by polymer structure and interfacial chemistry as by dosage. This review synthesises 50 primary sources (2003-2025, concentrated post-2015) to examine how PP molecular structure, fibre-manufacturing history, morphology, surface properties and environmental ageing govern fibre-matrix interaction and multiscale composite performance. Isotacticity, molecular weight, crystallinity and drawing ratio are shown to set the …

Status of Surfactant-Polymer Flooding
Abstract: Abstract Surfactant-polymer (SP) flooding emerged from the principle that good sweep efficiency and displacement efficiency result in good oil recovery. Its research and development was shifted to alkaline-surfactant-polymer (ASP) because higher oil recovery can be achieved from the latter. Apparently, some research-development focus is coming back to SP, because ASP has problems in practical applications, e.g., scaling and emulsion. This paper provides the status of surfactant-polymer flooding technology. It covers …

Status of Phosphatases in Basella alba L. Leaves During Water Stress
Abstract: Activity of acid phosphatase and alkaline phosphatase in the leaves of medicinally important plant Basella alba with respect to its two cultivars under water deficit and water logging stress was estimated. It was recorded that the activity of both the phosphatases increased with increase in water stresses with single exception. The increased activities probably help in release of inorganic phosphates at intracellular level that might regulate proper plant metabolism which …

Understanding the Molecular Mechanisms of Proteases in Bioprocessing: A Review on the Future of the Food Industry
Abstract: Proteases are enzymes that break down proteins through peptide bond catalysis. A protease is a single polypeptide chain of some 250 amino acids and is devoid of sulfhydryl groups. The COOH-terminal tryptic peptide of the protease molecule contains some 43 residues. Because of this unique structure and mechanism, they play a crucial role in the Bioprocessing industry, especially in food processing applications. Herein, the sources of proteases are discussed as …

A Review of Properties of Geopolymer Concrete
Abstract: The growing need for concrete around the world has led to both more concrete being made and more of it being used. Carbon dioxide is released into the atmosphere when regular Portland cement is made, which contributes to global warming (OPC). because concrete that is good for the environment needs new kinds of binders. Using different binders could cut down on the energy needed to make traditional concrete and the …

A Critical Review on Semi-solid and Solid Lubricants for Industrial Applications
Abstract: Friction materials are very important for the safe moving of automobiles and the safety of people. As the pad slides against its match, the moving energy is turned into heat by the friction. As the vehicle's speed is lost as heat in the pads and rotors, the friction at the contact slows it down. Lubricants are compounds that are applied to moving parts to reduce friction and wear. Used primarily …
