热带甲壳虫拥有最明亮的白色

隐藏在明亮的一种罕见的热带甲壳虫白色外壳后面的秘密是一种不常见的非周期结构。英国物理学们通过电子显微镜揭示出一种随机的蛋白质丝状网络使得该种甲壳虫的外壳拥有非常高的光线散射效率。这种蛋白质结构拥有比人造相同散射效率的材料薄两个量级的厚度,可以用于改进相关的产品。

Tropical beetle has the brightest whites (Jan 18)

The secret behind the brilliant white shell of a peculiar tropical beetle is an unusual, aperiodic structure, according to physicists from the UK. Electron microscopy revealed that a random network of protein filaments allows the shell to scatter light with high efficiency. The protein structure, which is at least two orders of magnitude thinner than manmade materials of equivalent whiteness, could be imitated in future synthetic systems (Science 315 348).
