The kinetic and mechanistic studies of Ru(III) and Ir(III) homogeneously catalyzed oxidation of d-fructose (d-fru) by N-bromophthalimide (NBP) in the presence of aqueous perchloric acid medium have been made at 303 K using mercuric acetate as Br- ion scavenger. The stoichiometry and the oxidation products in both catalysts were found to be the same. The determined stoichiometric ratio was found to be 1:2 ([d-fru]:[NBP]). Arabinonic and formic acids were obtained as the major oxidized products of both the reactions. The kinetics of the reaction were studied as a function of temperature, ionic strength, concentration of the salt, concentration of the added reaction product, and the dielectric constant of the medium to learn the mechanistic aspects of the reaction. Possible mechanisms are proposed, which are consistent with the kinetics, stoichiometry and products of the reaction. © 2013. Source

In this paper a hybrid power system combining animal energy and human energy is experimentally studied to supply continuous power to home lighting applications. The animal systems is used as main energy source while the human system is used as secondary or back-up energy source. This invention provides animal powered and human powered mechanical device for prime mover to electric generator. Human and animal energy in form of high-torque low-speed can be converted into low-torque high-speed through speed increaser to energize the electric generator. The electricity generated is stored in the battery and used when lighting is required either for DC light or AC light using inverter. This equipment is emission free, low cost and has long life. Also this equipment needs less maintenance and any person can run either skilled or unskilled. © Research India Publications. Source
