Room temperature ionic liquid [1-butyl-3-methylimidazolium]BF4 was prepared under microwave irradiation. Platinum （Pt） nanoparticles were synthesized in the ionic liquid with ethanol as reductant. The structure and morphology of the Pt nanoparticles were characterized by SEM, FTIR and TG-DTA. The results show that the mean diameter of the nanoparticles was about 10nm and the surface was modified with the room temperature ionic liquid. The catalytic property was evaluated by hydrogenation of benzaldehyde in ethanol and the conversion reached up to 80% under hydrogen pressure.

粉煤灰中氧化铝质量分数可达15%-40%,是制备氧化铝和氢氧化铝的很好资源。综述了近年来国内外从粉煤灰中提取氧化铝的制备工艺及进展,主要分为酸浸取法及烧结法。分别从各制备工艺的特点、优点及其存在的缺陷等方面进行简要的评述,并对其发展趋势进行了阐述。传统制备工艺不同程度地存在能量消耗高、产生二次污染、生产周期长、提取率不稳等不足。采用超声波、微波等新技术代替传统制备工艺中的煅烧、研磨和氟化物助溶等高耗能、高污染的技术将具有广阔的应用前景。

自中国电影诞生之日起,电影与话剧就存在着千丝万缕的联系。二者皆为舶来品,其艺术形式、呈现空间与传播条件相似,因此自然而然地携起手来,在互动中批评与自我批评、相互促进,在差异式的“重复性”循环中螺旋式提升。20世纪一二十年代,文明戏出身的编导影响了早期电影的形态建构;30年代,随着左翼运动兴起,大批剧人跨入影界后又重返舞台,令戏剧与电影产生前所未有的深度交流.

在分析纺轮基本结构及运动特点的基础上,对纺轮的旋转过程进行了力学解析,对比分析了纺轮材质和形制对其纺纱的影响。研究表明,纺轮的材质、形状、半径是影响其纺纱平稳性的重要因素。体积相同,材质不同的纺轮具有不同的动能储备。密度越大,动能储备更大,旋转起来更省力,加捻平稳性更好。纺轮直径大小是其加捻平稳性的最大相关量,质量大小是牵伸平稳性的最大相关量,圆饼型纺轮的加捻平稳性最好。纺轮材质、质量和形状的密切配合,才能使得纺轮这一纺纱工具的牵伸和加捻组合平稳性同步提升。

VO2 thin films were obtained from V2O5 thin film in the thermal decompose process. V2O5 thin films were prepared in the spin-coating way and with V2O5 sol-gels as raw materials fabricated by the reformative inorganic sol-gel method. The effects of the viscosity of colloid on the fabrication of V2O5 film and the thermal decomposing temperature on the fabrication of VO2 film were studied. The results show that the appropriate viscosity of colloid to obtain well-distributed V2O5 film was in the range of 30g/L-40g/L and suitable thermal decomposing temperature was about 500℃.

Study on the SiC-Al Co-continuous Phase Composites

中国材料大会2012

ISBN: (纸本)9783037856079

SiC/Al co-continuous phase composites were fabricated by pressureless infiltration technology with reticulated silicon carbide porous ceramics as matrix and aluminum or magnesium as reinforcement phase. The effect of magnesium addition and holding time on the relative density, mechanical properties and macro morphology of the composites was investigated. The results showed that the porosity of SiC/Al co-continuous phase composites decreased with the increase of the holding time. The wettability of SiC and Al was improved with the addition of Mg. The hardness of SiC/Al co-continuous phase composites increased with the increase of the holding time. SiC and Al combined closely at longer holding time.

Reticulated silicon carbide porous ceramics was fabricated through organic foam infiltration process by using silicon carbide slurry prepared from silicon carbide, alumina and clay and other raw materials. The effect of solid content on the viscosity and Zeta potential of the slurry were investigated. The results showed that the viscosity of slurry increased with the increase of the solid content. The absolute value of Zeta potential increased with the increase of pH value of the slurry from acid to alkaline aptitudes, and it became smaller with the further increase of the pH value. The maximum was reached at the pH around 10. The viscosity of slurry in the range of 4000mPa s 5000mPa s was appropriate to prepare reticulated silicon carbide porous ceramics. The sintered body collapsed or cracked apparently, when the viscosity was too low. On the other hand, the viscosity could not be too high because it’s hard for slurry to impregnate foam. The performance of the samples coated once and recoated was compared. The porosity of the sample with one layer was higher than that of the samples with two layers. However, the recoating process improved the compressive strength and flexural strength of the reticulated silicon carbide porous ceramic.

目的研究大鼠放射性脑损伤模型中葡萄糖代谢与神经元活性的相关性,探讨2-18F-2-脱氧-D-葡萄糖(18F-FDG)micro-PET用于放射性认知功能障碍评估的潜在价值。方法将3周龄雄性SD大鼠按照随机数表法分成对照组以及全脑照射组,每组10只,脑照射组利用小动物精确放疗仪给予10 Gy X射线照射,对照组不予照射。通过Morris水迷宫(MWM)实验评估大鼠认知功能,对两组大鼠脑部micro-PET图像数据进行对比分析,免疫组织化学染色检测神经元活性标记物c-Fos蛋白在脑内的表达变化,免疫荧光染色检测幼稚神经元标志物DCX及新生成熟神经元标志物BrdU/NeuN阳性细胞数的变化。结果照射3个月后,与对照组相比,全脑照射的大鼠在MWM定向航行实验中第2至4天的潜伏期均显著延长(t=2.179、3.393、3.219,P<0.05),MWM空间探索实验中的目标象限的探索时间百分比减少(t=3.857,P<0.01),提示全脑照射可引起海马依赖性认知能力下降;SPM分析micro-PET图像显示全脑照射组海马区域葡萄糖代谢显著降低(t=5.12,P<0.05);此外,全脑照射组海马区域神经元活性标记蛋白c-Fos的表达显著减少(t=14.22,P<0.01),幼稚神经元标志物DCX及新生成熟神经元标志物BrdU/NeuN阳性细胞数均较对照组减少(t=18.77、9.304,P<0.01)。结论全脑放疗后海马区域的葡萄糖代谢减低,与海马神经元活性下降及神经发生减少相一致,表明18F-FDG micro-PET可以作为评估放射性认知功能障碍的有效方法。
