Guar the use of guar gum in the hydraulic fracturing (fracking) extraction of oil and shale gas, the demand has increased substantially. Only 10% of the Indian production stays within the country and the remaining 90% is exported for shale gas and oil industries. Consequently, many former cotton or wheat fields are converted into guar fields as production costs are also lower. But the increase of guar gum prices also has other reasons. Guar The Guar or cluster bean, with the botanical name Cyamopsis tetragonoloba, is an annual legume and the source of guar gum. It is also known as Gavar,
Sol–gel process for a variety of medical applications. A sol–gel processed alumina can be used as a carrier for the sustained delivery of drugs and as an established wound healer. A marked decrease in scar size was observed because of the wound healing composite including sol–gel processed alumina. A novel approach to thrombolysis treatment is possible by developing a new family of injectable composites: plasminogen activator entrapped within alumina. Sol–gel process In materials science, the sol–gel process is a method for producing solid materials from small molecules. The method is used for the fabrication of metal oxides, especially the oxides of silicon
