Principales procesos que impactan la calidad del agua para el riego en pozos costeros del centro sur cubanoProcesses impacting irrigation water quality in several coastal wells of Center-Southern Cuba
(Universidad Nacional Autónoma de México. Centro Ciencias de la Atmósfera, 2019-03)
La calidad del agua constituye una variable a controlar en la agricultura de regadío. El objetivo de la investigación fue identificar los principales procesos que impactaron la calidad del agua para el riego en pozos ...
Pyrolytic coproduction of biochar and upgraded biooils from abundant agroindustrial wastes
(Brazilian Society of Chemical Engineering, 2021-09-30)
The co-production of bio-char and upgraded bio-oil by fast pyrolysis of raw and sulfuric-acid pretreated agro-industrial wastes (corn cob, sugarcane bagasse and sunfower seed hull) was investigated to valorize wastes as ...
Chemistry of NOx on TiO2 surfaces studied by ambient pressure XPS: Products, effect of UV irradiation, water, and coadsorbed K +
(American Chemical Society, 2013-02)
Self-cleaning surfaces containing TiO2 nanoparticles have been postulated to efficiently remove NOx from the atmosphere. However, UV irradiation of NOx adsorbed on TiO2 also was shown to form harmful gas-phase byproducts ...
Theoretical study of N2O2 interaction with BaO(100) surface
(Elsevier Science, 2007-12)
In this work, the adsorption of the NO dimer on BaO(1 0 0) was studied using the density functional theory (DFT). N2O2 interacts with the surface mainly in three different ways. In the more favoured orientation it adsorbs ...
Confinement Effects in Protonation Reactions Catalyzed by Zeolites with Large Void Structures
(American Chemical Society, 2018-12)
In the present work, we studied the protonation reaction of styrene inside the cavity of acidic H-Y zeolite. Density functional theory calculation using M06-2X functional and analysis of quantum theory of atoms in molecules ...
Nanoarchitectonics of metal organic frameworks and PEDOT layer-by-layer electrodes for boosting oxygen reduction reaction
(Royal Society of Chemistry, 2021-09)
We present a strategy for the integration of three building blocks in a functional interfacial nano- architecture in order to fabricate composite films with improved features towards the electrochemical oxygen reduction ...
Effect of the electrode potential on the surface composition and crystal structure of LiMn2O4 in aqueous solutions
(Pergamon-Elsevier Science Ltd, 2018-04)
Cubic spinel LiMn2O4 has been studied for the reversible extraction of Li+ from natural brine after the application of suitable electrode potentials. In this work we report on the insertion/extraction of Li+ from natural ...
Hydrogeochemistry and isotope techniques to determine water interactions in groundwater-dependent shallow lakes, Wet Pampa Plain, Argentina
(Springer, 2014-02)
This paper gives an account of the implementation of hydrochemical and isotopic techniques to identify and explain the processes that govern solute exchange in two groundwater-dependent shallow lakes in the Southeastern ...
Síntesis de zeolitas ZSM-11 con porosidad jerarquizadaSynthesis of hierarchical ZSM-11 zeolites
(Universidad Tecnológica Nacional, 2019-10-16)
En este trabajo se propone la creación de porosidad adicional en zeolitas microporosas con estructura ZSM-11 mediante síntesis directa utilizando un surfactante catiónico (CTAB) como plantilla mesoporosa. Se investigó el ...
Catalytic performance of V-MCM-41 nanocomposites in liquid phase limonene oxidation: Vanadium leaching mitigation
(Elsevier Science, 2021-02)
Chemical stability and catalytic performance of MCM-41 materials functionalized with vanadium by template-ion exchange (TIE) were studied. Solids with different vanadium loadings were synthesized and characterized by a ...
