Water Defluoridation: Nanofiltration vs Membrane Distillation
(American Chemical Society, 2018-10)
Nowadays, fluoride contamination of drinking water is a major problem for various countries, because high concentrations of fluoride pose a risk of dental and skeletal fluorosis. Over past years, membrane nanofiltration ...
Improving the osteointegration and bone–implant interface by incorporation of bioactive particles in sol–gel coatings of stainless steel implants
(Elsevier, 2009-10-14)
In this study, we report a hybrid organic–inorganic TEOS–MTES (tetraethylorthosilicate–methyltriethoxysilane) sol–gel-made coating as a potential solution to improve the in vivo performance of AISI 316L stainless steel, ...
Monofunctional epoxy-POSS dispersed in epoxy - Amine networks: Effect of a prereaction on the morphology and crystallinity of POSS domains
(American Chemical Society, 2007-02)
Several studies have recently reported the use of monofunctional octahedral oligomeric silsesquioxanes (monofunctional POSS) to modify polymer networks. In most of these studies the final material is depicted as a network ...
Mapping of a Regulatory Site of the Escherichia coli ADP-Glucose Pyrophosphorylase
(Frontiers Media S.A., 2019-09)
The enzyme ADP-glucose pyrophosphorylase (ADP-Glc PPase) controls the biosynthesis of glycogen in bacteria and starch in plants. It is regulated by various activators in different organisms according to their metabolic ...
New thiourea and urea derivatives containing trifluoromethyl- and bis-triflouromethyl-4H-chromen-3-yl substituents
(Taylor & Francis Ltd, 2019-02)
Two new thiourea (1) and urea (2) derivatives, substituted with 2-trifluoromethyl-4H-chromen-3-yl moieties at defined positions, were obtained by convenient synthetic methodologies. The pure compounds were studied in solid ...
Temperature dependence of the effective interdimer exchange interaction in a weakly coupled antiferromagnetic dimer copper compound
(American Physical Society, 2017-08)
We report a variation with temperature T of the effective interdimeric interaction J´eff in the antiferromagnetic (AFM) copper dimeric organic compound Cu2[TzTs]4 (N-thiazol-2-yl-toluenesulfonamidate CuII). This T dependence ...
Hierarchical assemblies of gold nanoparticles at the surface of a film formed by a bridged silsesquioxane containing pendant dodecyl chains
(American Chemical Society, 2009-01)
Hierarchical aggregates of gold nanoparticles (NPs) on different length scales were in situ generated at the surface of a bridged silsesquioxane during the process of film formation by polycondensation and solvent evaporation. ...
Desarrollo y evaluación de un nuevo fertilizante nitrogenado de liberación lenta: complejo de inclusión de urea con ácido esteáricoEvaluation of new slow-release nitrogen fertilizer: inclusion complex of urea with stearic acid
(Universidad Nacional de La Plata, 2020-08-06)
La fertilización nitrogenada a gran escala y con productos o dosis inadecuados produce contaminación del suelo y napas, como así también la eutrofización de cuerpos de agua y la contaminación del aire, llevando a la formación ...
Hydrocarbon-bearing sulphate-polymetallic deposits at the Colipilli area, Neuquén Basin, Argentina: Implications in the petroleum system modeling
(Elsevier, 2021-04)
This work deals with the hydrocarbon-bearing barite-polymetallic mineralizations of the Colipilli area, located in the western sector of the Agrio Fold and Thrust Belt (Neuquén Basin, Argentina). The mineralizations consist ...
Enol-imino-keto-enamine tautomerism in a diazepine derivative: How decisive are the intermolecular interactions in the equilibrium?
(American Chemical Society, 2019-08)
The strange tautomeric equilibrium behaviour exhibited by a new o-hydroxyphenyl diazepine derivative, when the compound is analysed both in solution and solid state, open the structural study of the enol-imino-keto-enamine ...
