Kinetics and reaction mechanism of biothiols involved in SNAr reactions: an experimental study
(Frontiers Media, 2022)
Few kinetic parameters, or reaction rates, are known up to date in detail about 1-chloro and 1-fluoro-2,4-dinitrobenzene (ClDNB and FDNB, respectively) with a series of biothiols in aqueous media. These biological nucleophiles ...
A comprehensive kinetic simulation of different types of plant fibers: autocatalytic degradation mechanism
(2019-08-15)
Kinetic analysis of the non-isothermal degradation of three different plant fibers has been performed using isoconversional model-free methods, model-fitting methods in order to establish if different kinetic approaches ...
Analysis of the applicability of short time chronoamperometry for the kinetic study of the hydrogen oxidation reaction
(Elsevier, 2013-09)
This work analyses the applicability of the chronoamperometric method for the evaluation of the kinetic parameters of the hydrogen oxidation reaction. It consists in the application of an overpotential step and the subsequent ...
Criteria for the selection of the scan rate in the evaluation of the kinetic parameters of the hydrogen oxidation reaction by a potentiodynamic sweep
(Elsevier Science Sa, 2015-07)
The use of the current density values obtained from a voltammetric sweep at a slow scan rate jvs(η) in place of those of a steady state polarization jss(η) for the determination of the kinetic parameters of the hydrogen ...
The kinetics and mechanism of the reaction of ZINCON, o-[1-(2-hydroxy-5-sulfophenyl)-3-phenyl-5-formazane] benzoic acid, with Zn2+, Cu2+, and [Zn2++Cu2+] equimolar mixtures

Cure kinetics of diglycidylether of bisphenol A– ethylenediamine revisited using a mechanistic model
(John Wiley & Sons Inc, 2001-09-14)
The polymerization kinetics of the reaction between diglycidylether of bisphenol A (DGEBA) and ethylenediamine (EDA) was analyzed, using dynamic scanning calorimetry, in both isothermal and programmed heating-rate modes. ...
Study of the pozzolanic reaction kinetics in sugar cane bagasse-clay ash/calcium hydroxide system: kinetic parameters and pozzolanic activity
(THOMAS TELFORD PUBLISHING, 2009)
This paper presents a study of the pozzolanic reaction kinetics between calcium hydroxide and a mixture of sugar cane bagasse with 20 and 30% of clay, burned at 800 and 1000 degrees C (SCBCA) by electrical conductivity ...
Hydrolysis of acetic anhydride: Non-adiabatic calorimetric determination of kinetics and heat exchange
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
A simple calorimetric method to estimate both kinetics and heat transfer coefficients using temperature-versus-time data under non-adiabatic conditions is described for the reaction of hydrolysis of acetic anhydride. The ...
Activation energy for the reverse eutectoid reaction in hypo-eutectoid Cu-Al alloys
(Elsevier B.V., 2012-03-10)
The values of the activation energy for the reverse eutectoid reaction (alpha + gamma(1)) -> beta in the Cu-9 wt.%Al, Cu-10 wt.%Al and Cu-11 wt.%Al alloys were obtained using nonisothermal methods and considering two ...
