Chemistry 185 - Chemistry of Nanomaterials, Spring 2007

 

Tuesdays and Thursdays, 9:35 am to 10:50 am (1/16/2007 - 5/11/2007).

Location: Seaver North Laboratory, classroom 111

Prerequisite: 110A,B; MATH 31; PHYS 51A,B.

 

Office hours: Monday, Tuesday, Wednesday 1:00 pm to 3:00 pm.

 

Chemistry of Nanomaterials (CHEM 185) is a full semester course covering increasingly important topics such as soft matter, biophotonics, nanotechnology, and self-assembly. Although the field of nanomaterials is strictly interdisciplinary, this course will have a chemical perspective on the subject. Therefore a decent grasp of organic chemistry and physical chemistry is expected. There is no required textbook for this course but up to date developments from the chemical literature will be underscored whenever possible. Click here to go to the journals used in this course. The course is taught in four units and the schedule of topics to be covered is shown below. Unit 1 of the course will begin with fundamental material, namely the physical chemistry of phenomena manifested at the nanoscale where surface effects become important.  The introductory material will also cover self-assembly and adsorption. This will provide a sound background to discuss nanomaterials and their applications (unit 2). Unit 3 will focus on specialized techniques that are routinely used to characterize nanomaterials. The final unit will focus on biophotonics. Evaluation of the student’s performance in this course is based on one mid-term examination and a presentation. The 15 minute presentation will be on any topic relating to this course. The presentation will describe the findings of a recent journal article of choice. The comprehension of the paper, the quality of the presentation, and ability to answer questions will be used to evaluate the student’s performance in this course.

Useful References

 

Many different sources were used to compile the notes delivered in lecture. These notes in addition to any handouts should be sufficient for the course. Therefore, there is no required textbook. In fact most of the cutting edge work cannot be found in textbooks. The following references were used to compile the material used in this course. In addition to these books articles from the RSC journal Soft Matter and the ACS journals Langmuir and Nanoletters were used extensively. Most of the following books can be found in the College library. All of them can be found in my office.
