Most conventional aerosol neutralizers are based on radioactive sources, which are controlled by strict regulations restricting their handling, transport, and storage. The TSI 3087 soft X-ray （SXR） neutralizer circumvents these legal restrictions. The aim of the present work is to compare the performance of a standalone SXR aerosol neutralizer with that of conventional radioactive aerosol neutralizers based on 85Kr （TSI 3077） and 241Am （Grimm 5522） by performing field tests in a real environmental scenario. The results obtained when the SXR neutralizer was connected to a mobility particle sizer spectrometer （MPS）, different from the device suggested by the manufacturer, were comparable with those obtained with the use of radioactive aerosol neutralizers. In changing the neutralizer, the particle number concentrations, measured with the MPS connected to the SXR neutralizer, almost remained within the 10% uncertainty bounds for the particle size interval 10-300 nm, when diffusion losses inside the SXR tube were considered. Based on our comparisons, the SXR neutralizer can be regarded as a standalone instrument that could solve the problems associated with legal restrictions on radioactive neutralizers and fulfil the need for a portable instrument for different field test purposes.

为缩短实验室样本制备时间,Milestone采用具有创新性的微波技术和特殊的温度探头设计出第一台超速微波组织处理仪URM.利用微波加速试剂对样本的渗透和加热作用,可以明显缩短实验室样本周转时间.Milestone微波组织处理方法中采用了多项国际专利技术, 改变了脱水模式,仅仅用95%乙醇进行脱水,并用异丙醇替代毒性较强的二甲苯.考虑到各种组织脂肪含量的不同,我们设计出两种基本的工作流程.对含中少量脂肪的组织可采用以下4个脱水步骤:(1)95%乙醇脱水;(2)异丙醇乙醇透明;(3)在较低功率微波条件下真空干燥;(4)浸蜡.为解决脂肪含量较多的组织不易吸收微波和脱水困难的问题,Milestone研制开发了一种脱水试剂***是由乙醇、异丙醇和长链碳水化合物组成的混合溶液,对脂肪含量较多的组织能取得理想的脱水效果,组织处理流程仅需3个步骤:(1)用JFC同步脱水与去脂透明;(2)真空干燥,避免组织损伤;(3)在预先设定的真空条件下进行浸蜡,这个过程同时还可以抽出残余的微量JFC.所以石蜡不受污染,可重复使用数次。

Preparation and Microstructural Characterization of Activated Carbon-Metal Oxide Hybrid Catalysts:New Insights into Reaction Paths

引用

Journal of Materials Science & Technology 2015年第8期31卷 806-814页

作者： A.Barroso-Bogeat M.Alexandre-franco C.Fernndez-Gonzlez V.Gómez-Serrano Department of Organic and Inorganic Chemistry Faculty of SciencesUniversity of Extremadura

In catalysis processes, activated carbon （AC） and metal oxides （MOs） are widely used either as catalysts or as catalyst supports because of their unique properties. A combination of AC and MO nanoparticles in a single hybrid material usually entails both chemical and microstructural changes, which may largely influence the potential catalytic suitability and performance of the resulting product. Here, the prepa- ration of a wide series of AC-MO hybrid catalysts is studied. Three series of such catalysts are prepared by support first of MO （Al2O3, Fe2O3, SnO2, TiO2, WO3, and ZnO） precursors on a granular AC by wet impregnation and oven-drying at 120 ℃, and by subsequent heat treatment at 200 or 850℃ in inert atmosphere. Both the chemical composition and microstructure are mainly investigated by powder X-ray diffraction. Yield and ash content are often strongly dependent on the MO precursor and heat treatment temperature, in particular for the Sn catalysts. With the temperature rise, trends are towards the transformation of metal hydroxides into metal oxides, crystallinity improvement, and occurrence of drastic composition changes, ultimately leading to the formation of metals in elemental state and even metal carbides. Reaction paths during the preparation are explored for various hybrid catalysts and new insights into them are provided.
