| 1 | 锐钛矿(TiO_2)含量对粉末冶金制备铝基复合材料磨损性能和显微硬度的影响(英文)显示文摘研究了锐钛矿(TiO_2)含量对铝基复合材料磨损性能和显微硬度的影响。采用粉末冶金方法制备不同TiO_2含量(0,4%,8%,12%,质量分数)的Al-15% SiC复合材料。在干摩擦条件下,采用盘-销装置进行磨损试验。采用X射线衍射仪、扫描电子显微镜(SEM)和能谱仪(EDS)对预制品进行表征。复合材料的光学显微组织表明TiO_2在基体中分布均匀。定量分析表明,随着TiO_2含量的增加,复合材料的抗磨损性能和显微硬度提高。SEM显微组织揭示了复合材料的高抗磨损性能与变形面的高位错密度和TiO_2的高硬度有关。磨屑的SEM组织表明随着TiO_2含量的增加,磨屑的尺寸逐渐减小。能谱分析证实氧化层的形成能明显地减小摩擦表面的有效接触面积,进而减小复合材料的磨损。分层和黏附磨损是主要的磨损机理。 | C.ANTONY VASANTHA KUMAR J.SELWIN RAJADURAI | 2016 | Transactions of Nonferrous Metals Society of China2016，26，1： | 2 |
| 2 | Evidence for a sequential transfer of iron amongst ferritin, transferrin and transferrin receptor during duodenal absorption of iron in rat and human显示文摘AIM: To elucidate the sequential transfer of iron amongst ferritin, transferrin and transferrin receptor under various iron status conditions. METHODS: Incorporation of 59Fe into mucosal and luminal proteins was carried out in control WKY rats. The sequential transfer of iron amongst ferritin, transferrin and transferrin receptor was carried out in iron deficient, control and iron overloaded rats. The duodenal proteins were subjected to immunoprecipitation and quantitation by specific ELISA and in situ localization by microautoradiography and immunohistochemistry in tandem duodenal sections. Human duodenal biopsy (n = 36) collected from subjects with differing iron status were also stained for these proteins. RESULTS: Ferritin was identified as the major protein that incorporated iron in a time-dependent manner in the duodenal mucosa. The concentration of mucosal ferritin was significantly higher in the iron excess group compared to control, iron deficient groups (731.5 ± 191.96 vs 308.3 ± 123.36, 731.5 ± 191.96 vs 256.0 ± 1.19, P < 0.005), while that of luminal transferrin which was significantly higher than the mucosal did not differ among the groups (10.9 ± 7.6 vs 0.87 ± 0.79, 11.1 ± 10.3 vs 0.80 ± 1.20, 6.8 ± 4.7 vs 0.61 ± 0.63, P < 0.001). In situ grading of proteins and iron, and their superimposition, suggested the occurrence of a sequential transfer of iron. This was demonstrated to occur through the initial binding of iron to luminal transferrin then to absorptive cell surface transferrin receptors. The staining intensity of these proteins variedaccording to the iron nutrition in humans, with intense staining of transferrin receptor observed in iron deficient subjects. CONCLUSION: It is concluded that the intestine takes up iron through a sequential transfer involving interaction of luminal transferrin, transferrin-transferrin receptor and ferritin. | Vasantha L Kolachala B Sesikeran K Madhavan Nair | 2007 | World Journal of Gastroenterology2007，13，7： | 2 |
