Reducing the allowable kinetic space by constructing ensemble of dynamic models with the same steady-state flux
(Elsevier, 2011-01)
Dynamic models of metabolism are instrumental for gaining insight and predicting possible outcomes of perturbations. Current approaches start from the selection of lumped enzyme kinetics and determine the parameters within ...
Complex SRO isothermal kinetics in quenched Cu-12 at.% Mn assessed by microhardness measurements
(ELSEVIER, 2006-01-15)
The isothermal kinetics of the return of short-range-order (SRO) in quenched Cu-12 at.% Mn alloy samples subsequently annealed at various temperatures was analyzed by means of microhardness measurements. An apparent ...
Hydrogen kinetics limitation of an autotrophic sulphate reduction reactor
(Universidad Nacional de Colombia Sede Medellín, 2012)
Sulphate-reducing bacteria (SRB) are microorganisms that can be used as removal agents in polluted water sources. The use of inorganic substrates in SRB systems could reduce the cost and simplify operation. However, the ...
Validation of the rancimat test for the assessment of the relative stability of fish oils
(American Oil Chemists' Society, 1996)
The induction periods for the peroxidation of various fish oils at 55-90°C were studied by the Rancimat test. The natural logarithms of the induction periods varied linearly with respect to temperature, with a mean coefficient ...
Quasi-isothermal DSC testing of epoxy adhesives using initial fast heating rates
(Wiley, 2017)
Three major factors decrease the accuracy of the cure measurement in standard-isothermal testing using differential scanning calorimetry (DSC). First, cure occurs during the heating step. Second, data are lost during the ...
Electrochemical method to study the environmental behavior of Glyphosate on volcanic soils: Proposal of adsorption-desorption and transport mechanisms
(Elsevier B.V., 2019)
Glyphosate is used extensively worldwide, but current evidence suggests detrimental effects on the environment, pollinators, and human health. Glyphosate adsorption kinetics and adsorption/desorption were studied through ...
Time Decay of the Activity of the Reduction Reaction of NO by CO on a Pd/Al2O3 Catalyst
(SPRINGER, 2008-11)
An experimental study is made of the time decay of activity of the CO-NO reaction on a Pd/Al2O3 looking at the effect on reaction order and apparent activation energy. The optimum kinetics parameters fitting the steady ...
Monte Carlo study of the influence of the structural heterogeneity of the surface in the CO-NO reaction on Pd and its relation with experimental data
(ELSEVIER, 2008-09-22)
The reduction reaction of NO by CO over Pd is studied by means of a Monte Carlo simulation. A reaction mechanism similar to that established previously in the literature for Rh and a set of recently published kinetics ...
The kinetic effect of H 2 O pressure on CO hydrogenation over different Rh cluster sizes
(Elsevier Ltd, 2019)
© 2018 Hydrogen Energy Publications LLC The effect of H 2 O pressure (P H2O ) on CH 4 formation turnover rate (TOF CH4 ) was evaluated as a function of Rh cluster size. In-situ DRIFTS and kinetic measurements were used to ...
Calculation of kinetic parameters beff and L with modified open source Monte Carlo code OpenMC(TD)
(Elsevier, 2022)
This work presents the methodology used to expand the capabilities of the Monte Carlo code OpenMC for the calculation of reactor kinetic parameters: effective delayed neutron fraction beff and neutron generation time L. ...
