The main object of this research is to investigate synthesis of Cu23Cl Cu and CuO nanoparticles through electrospinning and heat-treated method The research is mainly focused on preparative parameter and the change of heat-treated temperature to form the nanoparticles inlaid in silicon fibers the shape and color change are dicussed First of all to prepare the Polyvinyl butyral and silica dioxide complex nanofiber by electrospinning and then to investigate different heat-treated temperature and reactive time to being an influence on the products The results detected by SEM XRD TEM EDS FTIR combined sol-gel process and electrospinning can prepare Polyvinyl butyral and silica complex nanofiber The experimental result is found when heat-treated temperature is 100~4750C it can produce Cu23Cl nanoparticles; Above 4750C~ 4900C it can produce Cu nanoparticles; Above 450~7000C it can produce CuO nanoparticles And the viscosity is lain between 20~40cp and the sol-gel process time is 3hr it can produce the thinner fibers The average diameter of the fibers are 107 88±21 01nm;Due to the nanoparticles inlaid in the silica fibers the thinner fibers can be inlaid the smaller nanoparticles so this is the result that the experiment is expected To calcine the complex fibers is to produce surface silica fibers contain Cu23Cl Cu and CuO nanoparticles due to surface plasma resonance it make the color of the fibers become yellowish green from light white green turn into the red nuclear finally As the experimental result to utilize sol-gel process combine electrospinning can produce porous silica fibers contain Cu23Cl Cu and CuO nanoparticles
本研究旨在探讨「利用放电纺丝和热处理法来合成Cu23Cl、Cu和CuO奈米粒」之研究,实验著重在制备参数与热处理温度变化对所形成的奈米粒镶嵌在二氧化矽纤维中的形态与颜色变化探讨。首先,利用放电纺丝法制备出聚乙烯醇缩丁醛及二氧化矽之奈米纤维,比较不同的热处理温度与反应时间的改变对产物生成产生影响,进而研究不同热处理温度和时间对生成奈米粒的影响。产物经由SEM、XRD、TEM、EDS和FTIR等仪器分析结果显示,结合溶胶-凝胶法(sol-gel process)和放电纺丝法可产生聚乙烯醇缩丁醛及二氧化矽复合奈米纤维。实验结果发现,若热处理温度在100~4750C下可得到Cu23Cl奈米粒,475~4900C 可得Cu奈米粒,450~7000C以上可得 CuO奈米粒。而黏度介於20~40cp间和溶胶-凝胶时间为3hr时,可产生直径比较细的纤维,纤维直径为107 88±21 01nm;且由於奈米金属颗粒镶嵌在二氧化矽纤维中,直径比较细的纤维,可以得到比较小的奈米金属颗粒,这与实验预期相符。而锻烧此复合物产生多孔的二氧化矽纤维并包含Cu23Cl、Cu和CuO奈米微粒时,由於表面电浆子共震关系,而使纤维颜色由淡白黄绿色变成黄绿色,再变红褐色。由实验结果得知,利用溶胶-凝胶法(sol-gel process)结合放电纺丝法和不同热处理温度,可产生Cu23Cl、Cu和CuO奈米粒镶嵌在二氧化矽纤维。

Special staining methods, such as Masson and the Van Gieson staining were used to study the distribution of collogen fibers and elastic fibers. ResultsBy HE staining, the subepithelial connective tissues and vessels in the pterygium were more prominent than normal conjunctival tissues. An amorphous subepithelial superficial hyalinized zone and coarse eosinophilic granular materials were observed in the pterygia, but they were not found in normal conjunctival specimens. Coarse fibers were visible only in the deeper subepithelial connective tissues of pterygial samples. With Masson′s staining, the dense staining of collagen fibers was also more prominent in the pterygium than in the subepithelial connective tissues of normal conjunctiva. Abnormal collagen fibers were visible in the deeper sub-epithelial connective tissues of pterygial samples. With Van Gieson staining, abnormal collagen fibers were visible in the deeper subepithelial connective tissues. Dark coarse elastic fibers were found in the abnormal fibers only in the subepithelial deep connective tissues of pinguecula in the pterygia but not in the conjunctiva. With immunohistochemistry staining, MMP-3 was strong in the pterygial epithelium, moderate in fibroblast and absent from pterygial vascular walls. LN was strongly expressed in the blood vessel wall, moderately in the epithelial basement membrane and absent from the entire stroma.
结果HE染色:翼状胬肉组织上皮下基质中存在结缔组织的增生和血管形成;基质浅层存在一无定形物质透明区及粗糙的颗粒样嗜酸性物质,在翼状胬肉体部深层基质中存在粗糙的纤维组织;正常球结膜组织细胞排列整齐;基质为疏松结缔组织,胶原纤维平行排列,其间可见成纤维细胞,散在少量中性粒细胞、毛细血管;Masson染色:翼状胬肉浅层基质中存在致密的胶原纤维染色,深层基质中的胶原纤维存在变性样改变;VG染色:翼状胬肉组织深层基质中存在大量变性的胶原纤维,其间夹杂黑色的弹性纤维;免疫组化染色法:MMP-3在翼状胬肉上皮细胞中呈强表达,成纤维细胞中呈中等强度表达,血管内皮细胞中未见表达;LN在血管壁中呈强表达,在上皮细胞基底膜中呈中等强度表达,在整个基质中未见明显表达;col Ⅲ在整个翼状胬肉基质中呈强表达。

The results indicate that the longitudinal nerve fibers in cerebral ganglia and a few of small cells in the surface layer of cerebral ganglia present NOS positive reaction. Abundant NOS positive small cells are in the surface layer of pedal ganglia, and abundant transverse positive nerve fibers in the center of pedal ganglia. A large number of transverse positive nerve fibers are in the center of visceral ganglia; abundant positive small cells and nerve fibers are in two anterior lobes; a few of positive small cells and many encircled positive nerve fibers are in the posterior lobe; a large number of radiate positive nerve fibers are in the lateral lobes.
