Course Text
There is no text
required for this class, but Surface
Science, Foundations of Catalysis and Nanoscience is an excellent
resource. In addition, much of the
reading material for the course is available through the university’s Electronic
Course Reserve System. You can
also find course lecture notes by logging into your WebCT account.
Questions in Class
I encourage
discussion in class. Please feel
free to ask questions, before, during and after class.

Academic
Honesty
We expect students at the University of Georgia to adhere to
the highest standards of academic honesty and integrity. The UGA Student Handbook discusses the
University regulations regarding student academic conduct. Please familiarize yourself with these
regulations. All work presented by
you in this course is expected to be your own best effort, unless you are
specifically instructed to work with other students on a particular problem. Copying of the work of others, and particularly
plagiarism, which is the use of the work of others without proper credit or
citation, will not be tolerated.
The penalty for plagiarism or other academic dishonesty can include a
judicial hearing and possible assignment of an F grade in the course, or even
expulsion in extreme cases.
Additional Help
Professor John
Stickney is an excellent source of information on ultra-high vacuum surface
techniques and electrodeposition.
Professor Jim Anderson is an excellent source of knowledge on electrochemistry. They are very busy this semester, but I
am sure they would be willing to help.
Also, feel free to ask questions of my graduate students as well.

Grading:
Exams 30% (300 pts)
Quizzes/Homework 20% (200 pts)
Final Exam
Presentation 20% (200 pts)
Proposal 30% (300 pts)
Your course average
will be calculated based on the exams, quizzes, presentations and any other
assignments. The trend in your
performance does not matter. Your
overall course grade will be determined with respect to performance on class
norms.
Tests There will be two in class tests, each worth
15% of your overall grade:
Tuesday, September 19th.
Thursday, Oct. 26th.
Your grade will reflect your level of work in
this course, not any outside
influences. Work hard from the start,
as small differences in performance can make a big difference in your grade.
Quizzes/Homework
There will be a series of quizzes and
homework assignments worth a total of 20% of your final grade. The quizzes are unannounced and cover
work from recent previous lectures or presentations.
Attendance
Attendance is not mandatory, but I give pop
quizzes, especially if there are many people missing. Further, important announcements about
the class will be made during the lectures.
Final Exam
The final exam will be composed of an oral
presentation of literature reports related to a topic in nanotechnology and a
written presentation of a unique research proposal related to the subject
covered in the oral presentation. This is an opportunity for you to explore a
topic that interests you. As
part of your oral presentation, submit at least two recent (year 2001 to
present) peer-reviewed articles that are related to your chosen subject
1.
Oral Presentation (200 pts)
An oral
presentation of the final report will be scheduled for the last part of the
semester. A list of available dates
will be made available soon, and will be assigned on a first come first served
basis.
For the oral
presentation, provide the class with a brief overview of fundamental operating
principles, sensitivity, operating environments, types of samples,
advantages/disadvantages, etc., for this technique. Plan for your talk to
last 40 minutes, with additional time for questions. Consider this “practice” for
your departmental seminars.
It’s
okay to “borrow” figures from articles or websites, but the source
must be cited on the slide.
Every slide should deliver a key message.
Every slide should have a title & text.
2. Written
Proposal (300 pts)
The proposal is a
concise review of scientific literature related to your oral presentation (feel
free to use the same images and points used in your oral presentation) and then
a thorough explanation of your proposed line a research. The format of your proposal must conform
to the following: up to 15 single-spaced pages with size 12 font, including
figures. This page limit excludes
references.
a.)
Provide
a concise, but complete, discussion of previous work related to what you
propose (use the information you provided in your talk). (70 pts)
b.)
Summarize
the principle method of detection, its limits and environments (UHV/ambient?)
used for this technique. (60 pts)
c.)
Present
a unique research proposal that provides new knowledge in your area of
interest. This should include a
discussion of the intellectual merit of the proposed activity and the results
you intend to obtain. Also, give an
explicate explanation of the intellectual merit of the proposed activity; how
will it advance knowledge within its field? How important is it to a wider audience
(other fields)? (120 pts)
d.)
What
will be the outcome of the successful completion of your proposed work? What will you, and the wider scientific
community gain? (60 pts)
Points will be subtracted for bad grammar,
poor quality figures and, spelling errors.
It’s
okay to “borrow” figures from articles or websites and journal
articles, but the source must be cited in the figure caption.
Points will be added for creativity, design
& organization!
