Guar gum Ganganagar and Hanumangarh in Rajasthan are the major Guar trading markets. The United States has produced 4,600 to 14,000 tonnes of guar over the last 5 years. Texas acreage since 1999 has fluctuated from about 7,000 to 50,000 acres. The world production for guar gum and its derivatives is about 1.0 Million tonnes. Non-food guar gum accounts for about 40% of the total demand. Mainly it is used as a proppant transport / proppant suspending agent in hydraulic fracturing. At its peak the price was $8000 per ton.

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
