Nanostructured materials with extremely fine grain sizes, typically less than 100 nm, have been shown to exhibit extremely high strength and hardness, increased diffusivity, useful sintering characteristics, and other unusual properties. Significant developments have taken place in recent years in trying to achieve high strength and ductility at the same time. New and potential applications are also being sought after. Several commercial ventures have also started (estimated to be around 1000 in different parts of the world). This overview will present the recent developments in our understanding of the mechanical behavior and molecular dynamics simulation studies, highlight the present unresolved issues, and discuss some of the promising applications for these novel and exciting materials. 相似文献

Tubular and fibrous nanostructures of titanates have recently been synthesized and characterized. Three general approaches (template assisted, anodic oxidation, and alkaline hydrothermal) for the preparation of nanostructured titanate and TiO2 are reviewed. The crystal structures, morphologies, and mechanism of formation of nanostructured titanates produced by the alkaline hydrothermal method are critically discussed. The physicochemical properties of nanostructured titanates are highlighted and the links between properties and applications are emphasized. Examples of early applications of nanostructured titanates in catalysis, photocatalysis, electrocatalysis, lithium batteries, hydrogen storage, and solar‐cell technologies are reviewed. The stability of titanate nanotubes at elevated temperatures and in acid media is considered. 相似文献

纳米磁性材料及其应用 总被引:17,自引:0,他引:17
纳米磁性材料是纳米材料中最早进入工业化生产,应用十分广泛的一类功能材料,纳米磁性材料的特性不同于常规的磁性材料,其原因在于与磁性相关联的特征物理长庆恰好处于纳米量级,例如,磁单畴尺寸,超顺磁性临界尺寸,交换作用长度,以主电子平均自由路磁程自由路程等大致处于1-100nm量级,当磁性体的尺寸与这些特征物理长度相当时,就会呈现反常的磁学与电学性质,利用这些新特性,已涌现出一系列新材料与众多应用。 相似文献

In this introductory paper an attempt is made to give an overview of the area of nanostructured materials irrespective of the synthesis process. The various microstructural features such as clusters or isolated nanoparticles, agglomerated nanopowders, consolidated nanomaterials and nanocomposite materials as well as all materials classes are considered. As an important component of modern research on nanomaterials a section describes the various characterization tools available. Based on these remarks some properties of nanostructured materials will be summarized emphasizing the property–microstructure relationships. Finally, a brief outlook on applications and initial industrial use of nanomaterials is presented. 相似文献
