Effect of acid-methanol treatment on the physicochemical and structural characteristics of cassava and maize starches
Physicochemical, structural and morphological characteristics of maize and cassava starches treated with 0.36% concentrated HCl in anhydrous methanol at WC for 1-8 h were analyzed and compared. Average yield of modified ...
Effects of heat treatments on the electrocatalytic activity of Pt-Ru/C for methanol oxidation
The Pt-Ru/C materials of this study were prepared by a microemulsion method with fixed water to surfactant molar ratio and heat treated at low temperatures, to avoid changes in the average particle size, in different ...
Effects of Alloyed and Oxide Phases on Methanol Oxidation of Pt-Ru/C Nanocatalysts of the Same Particle Size
(Amer Chemical Soc, 2009-05-14)
In this work, methanol oxidation was studied on carbon-supported Pt-Ru nanocatalysts, where the amounts of alloyed and oxide phases were modified by heat treatments in different atmospheres. Because particle growth was ...
Performance of a DMFC Using Pt-Ru/C Catalysts Prepared by Reduction with Formic Acid
Butia Yatay coconut oil: Process development for biodiesel production and kinetics of esterification with ethanol
The aim of this work is to study biodiesel production using Butia Yatay coconut oil. This oil has acid values between 109 and 140 mg KOH/g, and phosphorus content in the order of 600 ppm. A three-step degumming pre-treatment ...
