Abstract. In the present work, hydrotalcite-like compound precursor for preparing mixed oxide catalyst was successfully synthesized by a novel method, which was a combination of the reverse microemulsion and coprecipitationmethods. It was observed that the precursor obtained from the above method possessed superior characteristics for preparing mixed oxide catalyst used in ethanol steam re…
Abstract. Nanosized semiconductor crystals can increase efficiency of photochemical reactions and greatly improve the catalytic activity of enzymes to generate novel photoelectrochemical systems. In this work, glucose oxidase (GOx)/zinc oxide (ZnO) is selected as a model system to assess the photovoltaic effect of semiconductor nanoparticles on the enzyme electrode. UV-spectrum and circular…
Abstract. We present a novel colloidal discotic system: the formation and self-assembling of wax microdisks with a narrow size distribution. Uniform wax emulsions are first fabricated by electrospraying of melt a-eicosene. The size of the emulsions can be flexibly tailored by varying the flow rate of the discontinuous phase, its electric conductivity, and the applied voltage. The process of…
Abstract. A core-shell structure material, carbon fiber/SnO2 was prepared by a surface modification precipitation process in aqueous solution. Results indicated that coating was obtained with 250 nm-thick SnO2 shell on the surface of carbon fiber from 0.05 M SnCl2. Optical properties of the composites were also investigated by photoluminescence (PL) spectroscopy. It was found that there is …
More than 300 plant orthoesters isolated in the past several decades were covered in this review. Plant orthoesters represent one category of structurally fascinating and biologically important plant metabolites. Their complex stereochemistry and the important biological activities, as wellas the available structure-activity relationship of some structural types of plant orthoesters, have provi…
