Lithium-ion battery pack arrays for lifespan enhancement
(2017 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)2017 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON), 12/21/2017)
Depending on the application, power and energy requirements may differ significantly and, most likely, a single lithium-ion cell will not suffice. Battery packs offer cell interconnections that allow to obtain several ...
Parameter optimization of an electrochemical and thermal model for a lithium-ion commercial battery
In this work, a LiFePO4/C commercial cylindrical battery cell is modeled with a P2D model coupled with a 2D axisymmetric heat transfer model to adequately represent the electrochemical and thermal responses of a battery. ...
Catanionic reverse micelles as an optimal microenvironment to alter the water electron donor capacity in a SN2 reaction
(American Chemical Society, 2019-02)
The effect of interfacial water entrapped in two types of catanionic reverse micelles (RMs) on the kinetic parameters of the SN2 reaction between dimethyl-4-nitrophenylsulfonium trifluoromethanesulfonate (S+) and n-butylamine ...
Phosphorus adsorption by a modified polyampholyte-diatomaceous earth material containing imidazole and carboxylic acid moieties: Batch and dynamic studies
(Royal Society of Chemistry, 2017-06)
The aim of this study was to investigate phosphorus removal in water by using a polyampholyte obtained by the reaction of methacrylic acid, ethylene glycol diglycidyl ether and imidazole by a one step synthesis, mixed with ...
Instability, political regimes and economic growth: A theoretical framework
(John Wiley & Sons Inc., 2021-11-25)
This paper models the influence of political instability on long-term economic growth. We consider three political systems associated to real-world political systems of increasing participation in policy-making. For each ...
Perspective of the distribution transformer in electric networks with high penetration of distributed generation and electric vehiclesPerspectiva del transformador de distribución en redes eléctricas con alta penetración de generación distribuida y vehículos eléctricos
(Universidad Militar Nueva Granada, 2016)
Photocatalytic Oxidation of Urea on Surface-Modified Bi 2 WO 6 with trans -4-Stilbenecarboxaldehyde
(American Chemical Society, 2021-06)
Modification of the Bi2WO6 surface with trans-4-stilbenecarboxaldehyde (4SCA) by the equilibrium adsorption method and its application in photoredox reactions under solar irradiation were studied. The modification of the ...
Hydrogenated amorphous silicon characterization from steady state photoconductive measurements
(IOP Publishing, 2019-03)
We propose to use steady state measurements and a teaching-learning-based optimization (TLBO) algorithm to get the complete set of material transport parameters of disordered semiconductors, taking undoped hydrogenated ...
