Unraveling the Radiation Damage of n-dodecanetiol Self-Assembled Monolayers on Au(100) and Au(111): a Prerequisite to Understand the Oriented-Attachment of Au Nanoparticles
(American Chemical Society, 2021-11)
We present a quantitative X-ray Photoelectron Spectroscopy study on the electron-induced degradation of Self-Assembled Monolayers of n-dodecanethiol on Au(100) and Au(111). This study is motivated by the lack of mechanistic ...
A two-stage hydrogen compressor based on (La,Ce,Nd,Pr)Ni5 intermetallics obtained by low energy mechanical alloying - Low temperature annealing treatment
(Pergamon-Elsevier Science Ltd, 2009-02)
La0.67Ce0.19Nd0.08Pr0.06Ni5 was synthesized by low energy mechanical alloying. The AB5 was milled up to completion stage to reach the final composition and appropriate particle size distribution and microstructure ...
Sorption and desorption of phosphate on biochar and biochar-soil mixtures
(2013-09-01)
The term biochar refers to materials with diverse chemical, physical and physicochemical characteristics that have potential as a soil amendment. The purpose of this study was to investigate the P sorption/desorption ...
Diseño de catalizadores de metales de transición a partir de materiales con estructura laminar, promovidos con tierras raras para la oxidación de COVs
(2012)
La presente investigación contribuye al diseño, síntesis y caracterización de estructuras laminares: hidrotalcitas de Co-Cu-Mg-Al y minerales arcillosos como precursores para la obtención de catalizadores de metales de ...
Improving of cold-start and combustion emissions in lean NO conditions with active and selective AgAl mesoporous catalysts
(Elsevier Science, 2019-03)
Mesoporous AgAl-MCM41 catalytic adsorbents were synthesized.Template-ion exchange (tie) and incipient wet impregnation (iwi) methodswere employed to incorporate Ag. The presence of non-structural andstructural Ag(I) ionic ...
Reservoir and contaminated sediments impacts in high-Andean environments: Morphodynamic interactions with biogeochemical processes
(2014)
Rapid changes due to anthropic interventions in high-altitude environments, such as the Altiplano
region in South America, require new approaches to understand the connections between
physical and biogeochemical processes. ...
Association of anions to cationic micelles
(1980)
The relative association degrees of different anions to micelles of hexadecyltrimethylammonium bromide (CTA) were measured by spectrophotometrically determining the amounts of p-toluenesulfonate (TOS) or benzenesulfonate ...
Efectividad de un hongo inmovilizado en alginato para solubilizar P y promover el crecimiento vegetal en suelos tropicales
(2018)
La deficiencia de fósforo (P) es un factor limitante para el desarrollo, crecimiento y productividad vegetal, afectando 2016 millones de ha a nivel global. Para corregir este problema se usan altas dosis de fertilizantes ...
