Abstract The adsorption of CO2 on Ba0.5Sr0.5Co0.8Fe0.2O3-d (BSCF) perovskite oxides in the absence and presence of O2 and H2O at various temperatures was investigated by temperature programmed desorption (TPD). XRD was used to characterize the phase of the samples before and after adsorption. No CO2 desorption peak was observed when CO2 was adsorbed on BSCF at room temperature. A CO2 desorpti…
Abstract. We report a modified method to synthesize SBA-16 mesostructured silica under refluxing condition using block co-polymer poly(ethylene oxide)–poly(propylene oxide)–poly(ethylene oxide) (F127) as template, cetyltrimethylammonium bromide (CTAB) as co-template, and tetraethyl orthosilicate (TEOS) as silica source. The physiochemical properties of SBA-16 silica were characterized b…
Abstract. Dye adsorption and microstructure of TiO2 film are important properties when it is used as photoelectrode of dye-sensitized solar cells (DSCs). This study investigated the application of a low crystallinity TiO2 film in DSCs. The low crystallinity TiO2 film is composed of interconnected spherical particles with an average size of 20 nm and has homogeneous mesoporous inner structur…
Abstract. The influence of CO pretreatment on the properties of CuO/CeO2/y-Al2O3 catalysts was investigated using X-ray diffraction (XRD), temperature programmed reduction (TPR), X-ray photoelectron spectroscopy (XPS) and infrared spectroscopy (IR). The activities of the treated catalysts were measured in low-temperature CO oxidation reactions (
Abstract. Chiral proline derivative was anchored on mesoporous SBA-15 materials by nucleophilic substitution of chloropropyl-functionalized SBA-15 with (S)-(-)-a,a-diphenyl-2-pyrrolidinemethanol. Chloropropylfunctionalized SBA-15 prepared by co-condensation of tetraethyl orthosilicate and 3-chloropropyltrimethoxysilane using P123 copolymer as the pore directing agent in strong acidic environ…
High temperature stress disturbs cellular homoeostasis and results in a severe retardation in crop growth and development. Thus, it is important to reveal the mechanism of plants coping with heat stress. In this study, a novel gene that we identified from Brassica napus, referred to as BnTR1, was found to play a key role in heat stress response in planta. BnTR1 is a membranebound RINGv (C4H…
