Dynamic response of CoSb2O6 trirutile-type oxides in a CO2 atmosphere at low-temperatures
(2014)
Experimental work on the synthesis of the CoSb2O6 oxide and its CO2 sensing properties is presented here. The oxide was synthesized by a microwave-assisted colloidal method in presence of ethylenediamine after calcination ...
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 ...
Diseño de placas funcionalmente gradadas mediante el método de optimización topológica para aplicaciones de impacto a velocidad baja y media.
(Universidad Nacional de ColombiaMedellín - Minas - Doctorado en Ingeniería - Ingeniería Mecánica y MecatrónicaDepartamento de Ingeniería MecánicaFacultad de MinasMedellín, ColombiaUniversidad Nacional de Colombia - Sede Medellín, 2021)
Los materiales funcionalmente graduados (MFGs) son un tipo de compuestos en los que la microestructura, la composición u otras características se modifican de forma continua a través de una o varias direcciones, lo que ...
Hydrogelsand metallo-hydrogels: characterization,and their environmental and pharmaceutical applications
(Nova Science Publishers, 2017)
The versatility on the applications of hydrogel materials make them veryattractive as adsorbents than can be used for decontamination of pollutants as well for drug-delivery. Adsorption is an efficient option for decontamination ...

Regional and large-scale patterns in Amazon forest structure and function are mediated by variations in soil physical and chemical properties
(Copernicus Publications, 2009)
Forest structure and dynamics have been noted to vary across the Amazon Basin in an east-west gradient in a pattern which coincides with variations in soil fertility and geology. This has resulted in the hypothesis that ...
An alternative gas sensor material: Synthesis and electrical characterization of SmCoO3
(2007)
Single-phase perovskite SmCoO3 was prepared by a wet-chemical synthesis technique using metal-nitrates and citric acid; after its characterization by thermal analyses and X-ray diffraction, sintering at 900 °C in air, gave ...

Energy Transfer between CNT Surface and -Re(CO)3(phen)+∗ Pendants Grafted to P4VP in Nanohybrid Shish-Kebob-like Structures
(American Chemical Society, 2019-12)
The adsorption of a Re(CO)3(phen)-poly(4-vinylpyridine) polymer, RePVP, on multiwall carbon nanotubes surfaces is studied by transmission electron microscopy and absorption spectroscopy in combination with chemometric ...
