Direct functionalization of Mn12-(methacrylate) clusters on Si(100): surface characterization and electrochemical properties
(2016-09)
The reaction of H–terminated Si(100) with methacrylate–substituted manganese carboxylate clusters [Mn12O12{CH2C(CH3)COO}16(H2O)4], [Mn12–(methacrylate)] via hydrosilylation afforded Mn12–(methacrylate)−Si(100). The chemically ...
Análisis fisicoquímico no invasivo de colgantes hachoides de piedras verdes de las colecciones arqueológicas del Museo Nacional de Costa Rica y del Museo del Jade y de la Cultura Precolombina
(2021-05)
Las sociedades precolombinas de la actual Costa Rica formaron uno de los principales
centros de producción de artefactos de jade y piedras verdes de Mesoamérica, los
colgantes hachoides fabricados en el actual territorio ...
Synthesis and Crystal Structure of a Copper(II) Benzoate Complex Bearing a Bis-2,2′-Tetrahydrofuryl Peroxide Moiety
(2018-12)
Complex [Cu2(ben)4·2THF−(η1–O2)]∞ (2) (ben=C6H5CO2− benzoate; THF=tetrahydrofuran) was isolated when a solution of Cu2(ben)4·2THF (1) in THF upon natural sunlight irradiation yields crystals suitable for single-crystal ...
Structural and functional role of anions in electrochemical water oxidation probed by arsenate incorporation into cobalt-oxide materials
(2019)
Direct (photo)electrochemical production of non-fossil fuels from water and CO2 requires water-oxidation catalysis at near-neutral pH in the presence of appropriate anions that serve as proton acceptors. We investigate the ...
Influence of bitumen and aggregate polarity on interfacial adhesion
(2017)
The quality of the bitumen–aggregate interface formed in an asphalt mixture is dictated by the physicochemical properties of both materials, such as surface polarity. In order to better understand the role of polarity on ...
Estudio de aditivos anticorrosivos para las aleaciones comerciales de la batería alcalina alumino-aire
(2020)
La sociedad actual está avanzando hacia un modelo energético más responsable y
sostenible. La punta de lanza de esta necesaria tendencia es el uso de fuentes de
energía renovables y la reducción de las emisiones de CO2 ...
Influence of nanosilica and diatomite on the physicochemical and mechanical properties of binder at unaged and oxidized conditions
(2016)
Modification of binders helps address common distresses in pavements by changing their essential properties. In order to further characterize the role of additives in these changes, a set of nanosilica and diatomite modified ...
Heterogeneous Water Oxidation: Surface Activity versus Amorphization Activation in Cobalt Phosphate Catalysts
(2015)
Is water oxidation catalyzed at the surface or within the bulk volume of solid oxide materials? This question is addressed for cobalt phosphate catalysts deposited on inert electrodes, namely crystallites of pakhomovskyite ...
