Utilization of Agricultural Waste for Defluoridation of Water: A Review
Abstract: Fluoride is an essential micronutrient for human health which can be obtained from food items. Excess fluoride is one of the anionic, inorganic contaminants, found predominantly in ground water due to weathering of rocks, geochemical reactions or anthropogenic activity such as disposal of industrial wastewaters, because of which removal of excess fluoride is mandatory. Among various methods used for defluoridation of water, adsorption is widely used. It is more remarkable …

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 …
