black phosphorus sentence in Hindi

Examples

1. Exfoliated black phosphorus sublimes at 400 �C in vacuum.
2. Black phosphorus is obtained by heating white phosphorus under high pressures ( about ).
3. Suspensions are then centrifuged for 30 minutes to filter out the unexfoliated black phosphorus.
4. Black phosphorus has an cubic crystal lattice structure.
5. A recent synthesis of black phosphorus using metal salts as catalysts has been reported.
6. It is predicted that crystal structure of black phosphorus can be discriminated under high pressure.
7. This is mostly due to the anisotropic compressibility of black phosphorus because of the asymmetrical crystal structures.
8. In scotch-tape-based microcleavage, phosphorene is mechanically exfoliated from a bulk of black phosphorus crystal using scotch-tape.
9. Heating white phosphorus under high ( GPa ) pressures converts it to black phosphorus which has a layered, graphite-like structure.
10. The structural transitions in phosphorus are reversible : upon releasing high pressure, black phosphorus gradually converts into the red allotrope, and by vaporizing red phosphorus at 490 �C in inert atmosphere and condensing the vapor, covalent red phosphorus can be transformed back into the white molecular solid.
