A kinetic and mechanistic study on the thermal decomposition reactions of cis- and trans- fused 1,2,4-trioxanes
(Asociación de Químicos e Ingenieros, 2003-09)
The kinetics of the thermal decomposition reactions of artemisinine (1), a cis-fused 1,2,4-trioxane, and trans-3,3dimethyl-1,2,4-trioxane (6) in solutions of benzene, toluene, and methanol in sealed tubes were compared at ...
Degradation of chlorpyrifos formulation in water by the UV/H2O2 process: Lumped kinetic modelling of total organic carbon removal
(Elsevier Science Sa, 2020-09)
The degradation of a commercial chlorpyrifos (CP) formulation solution under the UV/H2O2 process was predicted through a lumped kinetics modelling approach (LKA). The proposed models are based on different reaction schemes ...
A three dimensional kinetic Monte Carlo model for simulating the carbon/sulfur mesostructural evolutions of discharging lithium sulfur batteries
(Elsevier Science, 2020-01)
The carbon/sulfur composite cathodes of lithium sulfur batteries undergo mesostructural evolutions during discharge due to the dissolution/precipitation reactions of solid sulfur and Li2S. Furthermore, the cathode design ...
A new flow UV–Vis kinetics spectrophotometric method based on a photodegradative reaction for determining the oxidative stability of biodiesel
(Elsevier, 2020-02-15)
The biodiesel (BD) is an alternative fuel with some remarkable advantages compared to conventional diesel. However, the fatty acid methyl esters (FAMEs) which commonly compose BD are potentially oxidizable. This inherent ...
Finding the simplest mechanistic kinetic model describing the homogeneous catalytic hydrogenation of avermectin to ivermectin
(American Chemical Society, 2011-04)
Six mechanistic kinetic models of increasing complexity are analyzed to describe the RhCl(Ph3P)3 catalyzed hydrogenation process to produce ivermectin from avermectins B1a and B1b. Global sensitivity analysis (GSA) usefulness ...
Release kinetics of rosemary (Rosmarinus officinalis) polyphenols from polyvinyl alcohol (PVA) electrospun nanofibers in several food simulants
(Elsevier Ltd, 2018-12)
Polyvinyl alcohol (PVA) electrospun mats with antioxidant activity (PVA/Ros) were obtained by incorporating rosemary extract (RE) into the electrospinning precursor solution. RE compounds interact with PVA, favoring the ...
Advances in the study of the kinetics of color and fluorescence development in concentrated milk systems
(Elsevier, 2010-11)
The kinetics of color and fluorescence development in systems containing whole milk powder (WMP), sucrose (S) and water were studied; the influence of three design variables: pH (6, 7 and 8), temperature (105, 122.5 and ...
Water disinfection with UVC radiation and H2O2: a comparative study
(Royal Society of Chemistry, 2009-03)
A generalized kinetic model resulting from several modifications of the one originally known as the Series Event Model has been applied to describe three different disinfection processes and compare their efficiencies. The ...
Photocatalytic oxidation of oxalic acid in dilute aqueous solution, in a fully illuminated fluidized bed reactor
(Pergamon-Elsevier Science Ltd, 2010-12)
A comprehensive kinetic model for the photooxidation of oxalic acid (C2O4H4) in a fluidized bed (FB) of a TiO2/quartz sand composite, in a UV-fully illuminated photoreactor, was developed and correlated with experimental ...
Identifiability from a few species for a class of biochemical reaction networks
(Springer, 2019-07)
Under mass-action kinetics, biochemical reaction networks give rise to polynomial autonomous dynamical systems whose parameters are often difficult to estimate. We deal in this paper with the problem of identifying the ...
