2.      Reviews (~ 500 words) of published research papers on current lecture topics, four will be required during the semester (papers will be provided).

3.      The reviews and/or lab reports will be graded on difficulty of material, clarity, organization, critical/innovative input of student, and related criteria.  They will be due at the beginning of the class of the assigned due date.

4.      Homework will be assigned, but not graded, and solutions to some homework problems will be discussed in the class.

5.      Cheating is against University’s rules and regulations and will not be tolerated.

Lab 1.  Determine surface energy of various substances – the week of September 29th

Lab 2.  Pattern a glass surface and characterize the patterned surface – the week of Nov. 10th

(*Detail description of the labs will be provided one week prior to the lab)
