    • Materials, including metals such as bulk metals, specialty alloys, metallic films and coatings, are made up of many tiny single crystals, which may also be referred to as grains. The boundaries between crystals are called grain boundaries and govern properties such as mechanical strength, deformation, and electrical resistivity. These properties are affected by not only the number of grain boundaries formed, but also the density and orientation of those grain boundaries. Twin boundaries are a special type of grain boundary which have symmetrical “mirror image” structures and preserve favorable qualities of grain boundaries while suppressing unfavorable properties such as the initiation of cracks, inclusions, and other unwanted flaws. Some metals and alloys form twins more easily than others during processing. Metals with low stacking fault energy (SFE) such as austenitic stainless steel, copper (Cu), and silver (Ag) form twin boundaries more easily than metals with high SFE such as Magnesium (Mg) and Aluminum (Al).
    • 包括诸如散装金属,特种合金,金属膜和涂层的金属的材料由许多微小的单晶组成,其也可以称为晶粒。 晶体之间的边界称为晶界和管理性质,如机械强度,变形和电阻率。 这些性质不仅受到形成的晶粒数量的影响,还受到这些晶界的密度和取向的影响。 双边界是具有对称“镜像”结构的特殊类型的晶界,并且在抑制裂纹,夹杂物等不希望的缺陷的不利特性的同时保持晶界的有利品质。 一些金属和合金在加工过程中比其他金属和合金更容易形成双胞胎。 具有低堆垛层错能量(SFE)的金属如奥氏体不锈钢,铜(Cu)和银(Ag)比具有高SFE的金属如镁(Mg)和铝(Al)更容易形成双边界。

    • A low profile solar collector having a number of light collecting lenses that fit closely together as an array on a flexible sheet. The lenses may focus light onto optical conveyance mechanisms which convey light from the lenses to a light-to-electrical converter or converters at an edge of the sheet. The lenses may alternatively focus light onto a light-to-electrical converter or converters. Conductors may convey electricity from the light-to-electrical converters to an electrical connection block at an edge of the sheet. The flexible sheet may be rolled, folded, or form fitted onto a non-planar surface. Two or more low profile solar collectors having a number of collecting lenses may be combined to form a larger sheet for solar collection. The electrical outputs of the collectors may be connected to provide one or more outputs as desired.
    • 具有多个聚光透镜的低调太阳能收集器,其在柔性片上作为阵列紧密地配合在一起。 透镜可以将光聚焦到光学传送机构上,光学传送机构将光从透镜传送到光电转换器或在片的边缘处的转换器。 透镜可以可选地将光聚焦到光电转换器或转换器上。 导体可以将光从电 - 电转换器传送到片的边缘处的电连接块。 柔性片材可以被卷起,折叠或成形为非平面表面。 具有多个收集透镜的两个或多个低调太阳能收集器可以组合以形成用于太阳能收集的较大的片材。 收集器的电输出可以被连接以根据需要提供一个或多个输出。
