Most phononic crystals studied so far are constructed from periodically arranged objects (e.g., spheres or rods) immersed in a continuous solid or fluid medium. In this presentation, we investigate the properties of a different type of phononic crystal made by weakly brazing 4‐mm‐diameter alumi...
BEIJING, Aug. 14 (Xinhua) -- A large number of crystals with high purity have been found in purple-gold glazed porcelain excavated at the Palace Museum, also known as the Forbidden City, in Beijing. The crystals are dispersed across the glazed surface to a depth of approximately tens of m...
1983年, Takagi和Fukazawa[83]首次揭示了GSO: Ce的闪烁特性, GSO是Gd2O3-SiO2二元系统中唯一的三组分一致熔融材料, 密度为6.7 g cm-3, 单斜晶系, P21/c空间群, 在(100)面存在解理, 易开裂. 与BGO相比(表3), GSO:Ce具有较高的光输出、更短的衰减时间, 是继BGO之后一种新型的辐射探测器材料. 由于其...
The researchers have produced crystals of a semiconducting material called boron arsenide that has an extremely high thermal conductivity, a property that describes a material's ability to transport heat. "For high-powered, small electronics, we cannot use metal to dissipate heat because metal can ...
Single crystals of the important high-strength/high-temperature polymer poly(ether-ether-ketone) (PEEK) have been grown from dilute solutions in alpha -chloronaphthalene or benzophenone. The crystals possess an elongated, spear-like habit that becomes less pronounced at higher growth temperatures. The...
