Influence of sacrificial agent on Cu photodeposition over TiO2/MCH composites for photocatalytic hydrogen production
Martín-Gómez, Juan; Escamilla, Juan Carlos; Hidalgo-Carrillo, J.; López Tenllado, Francisco Javier; Estévez, R.; Herrera-Beurnio, M. Carmen; Castillo-Rodríguez, Miguel; Urbano, Francisco José; Marinas, Alberto (Elsevier, 2022)Titanium (ca. 11 wt%) was dispersed on a carbonaceous mesoporous support and modified with copper (ca. 5 wt%) photodeposited using either glycerol or methanol as the sacrificial agent ((Cu-TiO2/MCH_(Gly) and Cu-TiO2/MCH_(Met) ... -
Influence of the processing route on the carbon nanotubes dispersion and creep resistance of 3YTZP/SWCNTs nanocomposites
Castillo-Rodríguez, Miguel; Muñoz, A.; Morales-Rodríguez, Ana; Poyato, Rosalía; Gallardo-López, Ángela; Domínguez-Rodríguez, A. (The American Ceramic Society, 2014)3YTZP matrix composites containing 2.5 vol% of single-walled carbon nanotubes (SWCNT) were fabricated by Spark Plasma Sintering (SPS) at 1250°C, following different processing routines with the aim of optimizing the SWCNTs ... -
Microestructura y propiedades mecánicas a altas temperaturas del α-SiC sinterizado con fase líquida de Y2O3-Al2O3
Castillo-Rodríguez, Miguel; Muñoz, A.; Domínguez-Rodríguez, A. (Sociedad Española de Cerámica y Vidrio, 2005)Muestras de α-SiC han sido sinterizadas con fase líquida (LPS) a 1950 ºC, en atmósfera de argón y tiempos de procesado entre 1 y 7 horas. Mediante microscopia electrónica de barrido (SEM) se ha caracterizado la microestructura, ... -
Origin of the low precipitation hardening in magnesium alloys
Cepeda-Jiménez, C.M.; Castillo-Rodríguez, Miguel; Pérez-Prado, M.T. (Elsevier, 2019)In this work electron backscattered diffraction (EBSD)-assisted slip trace analysis and transmission electron microscopy have been utilized to investigate the interaction of basal dislocations with precipitates in the Mg ... -
Tensile deformation and fracture mechanisms of Cu/Nb nanolaminates studied by in situ TEM mechanical tests
Liu, Zhilin; Monclús, M. A.; Yang, L. W.; Castillo-Rodríguez, Miguel; Molina-Aldareguía, J. M.; Llorca, J. (Elsevier, 2018)The mechanisms of deformation and failure of Cu/Nb nanolaminates manufactured by accumulated roll bonding were analysed using in-situ TEM mechanical tests. Dog-bone small-scale tensile specimens were prepared using a ... -
The kink-pair mechanism and low-temperature flow-stress behaviour of strontium titanate single crystals
Castillo-Rodríguez, Miguel; Sigle, W. (Elsevier, 2011)The mechanical behaviour of strontium titanate exhibits a remarkable behaviour at low temperature, in the so-called regime A, where the flow stress experiences two different temperature dependences separated by a noticeably ... -
α-Al2O3 sapphire and rubies deformed by dual basal slip at intermediate temperatures (900–1300 °C): I. Dislocation organization
Castillo-Rodríguez, Miguel; Castaing, J.; Muñoz, A.; Veyssière, P.; Domínguez-Rodríguez, A. (Elsevier, 2009)Under a load orientation that hinders twinning and impedes fracture, sapphire and Cr-doped α-Al2O3 single crystals (rubies) were deformed from 1500 °C to slightly above the brittle to ductile transition temperature of 900 ... -
α-Al2O3 sapphire and rubies deformed by dual basal slip at intermediate temperatures (900–1300 °C): II. Dissociation and stacking faults
Castillo-Rodríguez, Miguel; Castaing, J.; Muñoz, A.; Veyssière, P.; Domínguez-Rodríguez, A. (Elsevier, 2009)Sapphire and rubies (undoped and Cr-doped α-Al2O3 single crystals) have been deformed in compression at temperatures lower than those previously used in studies of dislocations in the basal slip plane. Above 1400 °C, several ...
