Effect of acid-methanol treatment on the physicochemical and structural characteristics of cassava and maize starches
(Wiley-Blackwell, 2008-08-01)
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 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 ...

Butia Yatay coconut oil: Process development for biodiesel production and kinetics of esterification with ethanol
(Elsevier, 2014-06)
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 ...
The improvement of grape juice quality using Thermomucor Indicae-Seudaticae pectinase
(2020-04-01)
The effect of pectinolytic enzyme preparation (PEP) produced by the fungus Thermomucor indicae-seudaticae-N31 (PEP-N31) on total phenolic content, concentrations of methanol and color of grape juice was studied. Positive ...
