Claim 9:
10. A method of using an anhydrous fluid medium to prepare layered GeS, said method comprising:
providing a composition comprising bulk GeS and an anhydrous fluid medium, said anhydrous fluid medium comprising a fluid component having a surface tension at least partially sufficient to at least partially exfoliate said bulk GeS; and
sonicating said composition to provide a medium comprising nanomaterials comprising layered GeS comprising at least one of mono-layer, bi-layer, tri-layer and n-layer GeS, where n is 4-10, thereby modulating chemical degradation of said exfoliated GeS with said anhydrous fluid medium,
wherein said anhydrous fluid medium comprises N-methyl-2-pyrrolidone (NMP).
