There is growing interest in developing chemical and biochemical processes to obtain and modify biopolymers, and to other useful technical properties for their applications in different fields. The latest and most interesting example is chitin, it is mainly used for production of chitosan by a deacetylation reaction usually obtained in alkaline medium. Chitosan exhibits several favorable properties, such as biodegradability and biocompatibility. It also has mucoadhesive properties due to its positive charges at neutral pH that enable an ionic interaction with the negative charges of sialic...

Several alternative fuels like hydrogen, CNG, LNG, producer gas, biogas, alcohols, vegetable oils etc. are being explored around the globe with a view to supplement fuels and reduce environmental pollution. The alcohol fuels could not be exploited on a large scale because the petroleum fuels were abundant, cheap and easy to produce. Several vegetable oils are being produced in the country. Among vegetable oils rice bran oil can be used as CI engine fuel. Rice bran oil and its ester have been used satisfactorily for partial replacement of the diesel fuel. Use of vegetable oil and ethanol blend...
