Kinetic Study to Predict Sigma Phase Formation in Duplex Stainless Steels
(2016)
© 2016, The Minerals, Metals & Materials Society and ASM International.This work presents an improved kinetic study of sigma phase formation during isothermal aging between 973 K and 1223 K (700 °C and 950 °C), based on ...
Comportamento cinético do cloro livre em meio aquoso e formação de subprodutos da desinfecção
(2008-04-01)
One indirect approach to predict the disinfection by-product (DBP) formation potential for a given water source is by evaluation of the kinetic behavior of free chlorine in the liquid phase and chlorine demand determination ...
Determination of the intrinsic kinetic parameters of sulfide-oxidizing autotrophic denitrification in differential reactors containing immobilized biomass
(ELSEVIER SCI LTDOXFORD, 2012)
Nitrogen removal coupled with sulfide oxidation has potential for the treatment of effluents from anaerobic reactors because they contain sulfide, which can be used as an endogenous electron donor for denitrification. This ...
DNA hybridization mechanism in an interfacial environment: What hides beneath first order k (s(-1)) kinetic constant?
(Elsevier B.V. Sa, 2012-08-01)
The scientific question addressed in this work is: what hides beneath first order kinetic constant k (s(-1)) measured for hybridization of a DNA target on a biosensor surface. Kinetics hybridization curves were established ...

Investigação teórica da cinética de formação de hidratos de metano e dióxido de carbono
(Universidade Tecnológica Federal do ParanáCuritibaBrasilGraduação em Engenharia MecânicaUTFPR, 2017-07-07)
Hydrates are crystal structures that can be formed from the interaction of water molecules and low molecular weight gases such as methane, ethane, propane and carbon dioxide. These structures are formed under favorable ...
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 ...
Color kinetics and acrylamide formation in NaCl soaked potato chips
(ELSEVIER SCI LTD, 2007)
The objective of this work was to study the kinetics of color development in blanched and blanched-NaCl impregnated potato slices during frying by using the dynamic method and also to evaluate the effect of NaCl in reducing ...
