金属和玻璃如何融合?从表面上看来,金属和玻璃这两种物质的差别相当大:金属具有延展性且不透明,而玻璃则易碎而透明。透明的金属,或者用玻璃制成一枚导弹,这对人们来说是难以想象的。但是科学家们对这两种材料的研究表明,这些奇异的想法有可能变成现实。(1)玻璃金属美国得克萨斯州的赖斯大学和宾夕法尼亚州立大学的研究人员一直在研制透明金属,他们采用的是从迅速发展的“中孔性固体”研究领域借鉴的新技术。中孔性固体是一些内含有序小孔结构的材料,孔的直径只有几千纳米,是用二氧化硅球形颗粒确定孔状结构这一工艺制成的。这些二氧化硅球的直径为40纳米,
How Metals and Glass Merge? On the surface, the difference between metal and glass is considerable: metals are ductile and opaque, while glass is brittle and transparent. Transparent metal, or made of glass, a missile, which is unimaginable to people. But research by scientists on both materials suggests that these weird ideas are likely to come to fruition. (1) Glass Metals Researchers at Rice University in Pennsylvania and Penn State University have been developing transparent metals using new technologies borrowed from the rapidly growing field of “mesoporous solids.” Mesoporous solids are materials that contain ordered pore structures that are only a few thousand nanometers in diameter and are made from the process of determining the pore structure with spherical silica particles. These silica spheres are 40 nanometers in diameter,
