Project title: Tuning Pore Dimensions in Organically Modified Mesoporous Silica

Project description (50-100 words suggested): Mesoporous silica (MS) refers to an amorphous silica framework structure that is modulated by a regular (periodic) pore network obtained by hydrolysis and polycondensation of silicon alkoxide precursors in the presence of a structure-directing organic template. Most MS compounds are based on Si-O-Si bonds, but there is reason to create a more "flexible" framework by incorporating organic bridging group between 2 Si alkoxide moieties. In this project the student will use a silatrane (pentacoordinate silicon) and organically modified silicon alkoxide (OMSA) precursors to study (by TEM and surface area) how channel dimensions vary with OMSA content and identity. Chiral MS compounds based on chiral precursors will be examined.

Prerequisite: 1 term completed at McGill + CGPA of 3.0 or higher; or permission of instructor.

Grading scheme (The final report must be worth at least 50% of final grade): 50% final report; 40% laboratory work; 10% intermediate reports and literature search.

Project status: This project is taken; however students may contact the professor to discuss other possible '396' projects this term.

Ethics, safety, and training: Supervisors are responsible for the ethics and safety compliance of undergraduate students. This project involves NEITHER animal subjects, nor human subjects, nor biohazardous substances, nor radioactive materials, nor handling chemicals, nor using lasers.
