Synthesis of aluminum nitride in a coke – calcium reduction bed using nitrogen in air

引用

international Journal of minerals,metallurgy and materials 2015年第9期22卷 972-976页

作者： Ehsan noorizadeh Dehkordi H.r.Samim Banihashemi r.naghizadeh H.r.rezaie m.Goodarzi School of metallurgy & materials Engineering Iran University of Science & Technology

An experimental study on the heating of a mixture of aluminum and lithium hydroxide （LiOH） powders in a reductive bed under air atmosphere is reported. The formation of aluminum nitride （A1n） during this process was the focus of this study. The formation of A1n was achieved using LiOH as an additive and heating the sample in a resistance furnace in a specially designed double crucible within a bed of a mixture of coke and filamentous calcium. The temperature range of the reaction was between 700℃ and 1100℃. The optimum temperature of 1100℃ and the optimum LiOH amount （Swt%） required to achieve maximum yield were determined by powder X-ray diffraction （XrD） analysis. Scanning electron microscopy （SEm） micrographs clearly indicated the transformation of grain structures from rods （700℃） to cauliflower shapes （1100℃）.

A histological ground-section from a duck-billed dinosaur nestling(Hypacrosaurus stebingeri) revealed microstructures morphologically consistent with nuclei and chromosomes in cells within calcified *** hypothesized that this exceptional cellular preservation extended to the molecular level and had molecular features in common with extant avian cartilage. Histochemical and immunological evidence supports in situ preservation of extracellular matrix components found in extant cartilage, including glycosaminoglycans and collagen type ii. Furthermore, isolated Hypacrosaurus chondrocytes react positively with two DnA intercalating stains. Specific DnA staining is only observed inside the isolated cells, suggesting endogenous nuclear material survived fossilization. Our data support the hypothesis that calcified cartilage is preserved at the molecular level in this mesozoic material, and suggest that remnants of once-living chondrocytes, including their DnA, may preserve for millions of years.

Synthesis and characterization of CnT/Ce-TiO_2 nanocomposite for phenol degradation

引用

Journal of rare Earths 2012年第7期30卷 651-658页

作者： Shaari n Tan S H mohamed A r School of Chemical Engineering Engineering Campus University Sains Malaysia

An innovative photocatalyst, Carbon nanotube （CnT） supported Ce-TiO2 nanocomposite was successfully synthesized via modi-fied sol gel method and investigated in a batch reactor for abolition of phenol under UV light spectrum. Characterization of catalyst micro-structure and internal properties were done by means of X-ray diffraction （XrD）, Brunauer-Emmett-Teller （BET）, scanning electron micros-copy （SEm）, transmission electron microscopy （TEm） and UV-vis diffuse reflectance spectra （DrS）. Ce doping can inhibit phase transfor-mation from anatase to rutile and eliminate the recombination of electron-hole pairs in the catalyst. The presence of CnT in TiO2 composite can both increase the photoactivity under UV and change surface properties to achieve sensitivity to visible light. The optimum mass ratio of CnT support and cerium （Ce） dopant in TiO2 was the prominent factor to harvest CnT/Ce-TiO2 photocatalyst nanocomposite. The results demonstrated that optimum mass ratio of CnT：TiO2：Ce was 0.02：1.0：0.06, which resulted in the great performance of the photocatalyst to de-grade about 94% of phenol in a 50 mg/L solution in only 3 h. in this paper, dissimilar role of CnT support and Ce dopant in the TiO2 photo-catalysis of phenol was also discussed.
