Imagine catching a comet.
Comets are clusters of frozen gases passing close to the Earth at high speed, whose fate is to gradually evaporate until disappearing.

Scientists develop new method to isolate atomic sheets and create new materials
Two-dimensional materials from layered van der Waals (vdW) crystals hold great promise for electronic, optoelectronic, and quantum devices, but making/manufacturing them has been limited by the lack of high-throughput techniques for exfoliating single-crystal monolayers with sufficient size and high quality.
