## Title

- title: Scission of 2D Inorganic Nanosheets via Physical Adsorption on a Nonflat
    Surface
  title_type: original
  lang: en

## Description

- description: We report that titania nanosheets can be orthogonally sectioned into
    substantially rectangular-shaped fragments when deposited on a nonflat substrate
    surface via spin-coating their suspension. Such events occur for all the nanosheets
    on the substrate surface. In the deposition process, nanosheets float and stay
    flat on top of the solvent surface, and adsorb on the substrate with conforming
    to the bumpy surface by following the descending solvent level. Because the nanosheet
    area is smaller than the actual area of the bumpy surface having the same projected
    area, the nanosheet experiences tensile stress along its lateral direction. The
    tensile stress originates from the intermolecular forces acting between the nanosheet
    and the substrate surface upon the adsorption on the substrate. Due to the high
    2D anisotropy, the integrated intermolecular forces can be large enough to cleave
    the chemical bonds, leading to the scission of the nanosheet. This interesting
    finding may offer a new processing technique for cutting and shaping various 2D
    materials.
