Description
|
Cylindrical RPLC mesopore model generated with PoreMS. (a) Side view of the simulation box indicating the length of the central silica block and the solvent
reservoirs. (b) and (c) Front and side view, respectively, of the pierced silica block containing the 9nm diameter pore. The chemistry of the exterior surface is based on the (111) face of beta-cristobalite silica. Exterior planar and interior curved surface are covered with the bonded phase consisting of C18 chains as the main ligand and TMS groups for endcapping. Bonded-phase groups are randomly distributed on the silica surface. Ligand and endcapping densities, residual surface hydroxylation.
Colour code: Si, yellow lines; O, red lines; C18 chains, blue; TMS groups, magenta; residual surface silanol groups, yellow. |
