Obtaining Long-Chain Esters with Lubricant Properties from Sesame Biomass ,ine value, kinematic viscosity at 40 °C, and density at 20 °C were determined. The products were characterized by infrared spectroscopy and .H and .C nuclear magnetic resonance (NMR). The thermogravimetric analysis (TGA) of the bioproducts was realized and the main thermal events were evaluated.

Proton Modified Pt Zeolite Fuel Cell Electrocatalystson fine-structure (EXAFS) technique, Pt particle size was predicted as 0.7–1.5 nm. It was found Pt oxides can be electrochemically reduced via a hydrogen ‘spillover’ phenomenon. A highly dispersed small Pt particle distribution could be achieved with excessive H. ions on zeolite acidic sites.
