Visual representation of the structure of low-density amorphous ice. Many tiny crystallites (white) are concealed in the amorphous material (blue). “Space ice” contains tiny crystals and is not, as ...

Solids come in two main structural types—crystalline, with orderly repeating patterns, and amorphous, with disordered arrangements. These structural differences shape their physical properties, from ...

Water frozen in the depths of space has long been considered a shapeless, frozen fog. For decades, scientists believed it formed without structure, too cold and still to grow orderly crystals. But a ...

Researchers at Nagoya University in Japan have addressed a significant challenge in nanosheet technology. Their innovative approach employs surfactants to produce amorphous nanosheets from various ...

Scientists have long wondered how tiny silicate crystals, which need sizzling high temperatures to form, have found their way into frozen comets, born in the deep freeze of the solar system’s outer ...

Scientists have discovered that, in the crystalline solid Ba1-xSrxAl2O4, a highly disordered atomic arrangement is formed in the AlO4 network at chemical compositions near the structural quantum ...
