Junior Seminar Presentation

19 February 2010

three general types of projects
Three general types of projects
  • Linked to a course (usually this has been in CHM343 laboratory)
  • Projects generated largely due to an interest area of a student
  • Research loosely related to my interests
    • instrumental applications to investigate chemical systems
    • materials synthesis and characterization
    • noncovalent chemical interactions
