Directed
Studies (Chem 2094 or 4094) can be used to satisfy various requirements
depending on the college you are enrolled in. CLA majors must take at
least 2 credits of research. Any credits beyond that in either 2094 or
4094 are used as general elective credits only. If you are in CSE you
can use up to 2 credits in the Advanced Technical Electives (either 2094
or 4094) or in the Advanced Chem Lab Requirement (4094 only) but not
in both. Any credits beyond the 2 are used as general elective credits
only. If you wish to get credit for Chem 4094 the directed studies project
must be with a member of the Chemistry faculty or a member from another
department provided the project is in collaboration with someone from
the Chemistry faculty. If the project outside the department is not in
collaboration with a chemistry faculty member, it is possible, by petition
only, to get credit for Chem 2094 provided the project has enough of
a chemistry component.
To register for Chem 4094 you must be
upper division or be currently registered for (or have already completed)
a upper level Chemistry course. A student can not get credit and pay
during the same semester. For Chem 4094 a written report of approximately
10-15 pages is mandatory. The faculty mentor should make the effort to
spend time with the students in order to discuss the format for the report
and then provide feedback on the initial drafts. If a CSE student selects
Chem 4094 as one of the advanced labs to meet degree requirements, then
he or she must register for a TOTAL of 2 credits. This could be done
in one or more semesters. If it is spread out over more than one semester,
then the written report would only be required at the end. In the latter
case, the instructor gives a Continuation Grade (X) until the work is
finished and the report is submitted. Each credit normally requires 45
hours of academic work per semester, so 2 credits of research should
require about 90 hours of work in the lab. This turns out to be about
the same as other advanced labs.
If a student wishes to gain some research
experience in chemistry but does not wish to meet the writing requirement
in Chem 4094 or use that research experience to satisfy the advanced
chemistry lab requirement, then they should register for Chem 2094. CLA
students can also satisfy the "major project" requirement by
doing a library research project and submitting a written report of approximately
20-30 pages. In this case, they should also register for Chem 2094 for
at least 2 credits. Students who plan to graduate with Latin degree honors
will be required to have completed the requirements in Chem 4094, to
write up their work as a senior thesis of approximately 30-40 pages,
and to present their work orally to a committee consisting of three members
of the faculty.
Credit assignments vary; normally each credit earned requires
45 hours of academic work a semester. There is no pay connected with
this work, but it gives students excellent laboratory experience.
Research
For Pay UROP is a University program allowing students to work in conjunction
with faculty on faculty research. Financial awards to undergraduates
for research, scholarly, or creative projects include stipends (up
to $1400) and/or expense allowances (up to $300), for a maximum award
of $1,700. For more information and application material see the UROP
Office in 233 Appleby Hall, 625-3853. Particular attention should be
paid to the deadlines for applications. Students have had a high probability
for success in receiving UROP support. If you receive financial support
for doing research do not register for Directed Studies.
How to go about doing research:
You need to make arrangements with a faculty advisor. These
are the steps:
Look over the research that is being done in our
department. See the listings below on this page. This
will give you an idea of the projects and expectations. If
you know you are interested in a particular area of chemistry you can
look at the research of those faculty only at http://www.chem.umn.edu/directory/fac_listing_spec.lasso.
It may be that you want to work with someone who is not listed - that
is possible as long as it has a chemistry component to it. Pick out about
3-4 projects that seem interesting to you and contact those faculty. It
is important that you don't put out a generic email asking for work in
a lab. Be specific about
what it is about their research that interests you. Also sell yourself. "I
have two years to commit to a project and hope to go on to graduate school
someday." No one will want you for one term so plan to commit
to at least two terms. Ask to meet with them to talk about opportunities.
Once you've met with them you should have an idea who you want to work
for. Make sure you have an agreement with them as to how
much time they would like to see you in the lab for the number of credits
you plan to register for. Be sure to let others know you found
a different project and thank them for their time. Contact Stephanie
Stathopoulos at stephs@umn.edu for
a permission number and let her know who you are working for.
CHEM4094(W) or (V) Reporting Requirements
As a writing intensive course, CHEM4094W(V) includes
the requirement that students submit a final report on their
directed studies. In order to help maintain a record of meeting this
requirement, starting in the Fall Semester of 2010, a copy of the final
report from the student must be submitted to the undergraduate office.
Reporting: The faculty
advisor should submit both the final grade and final report (in PDF
format) simultaneously via email to Stephanie Stathopoulos (stephs@umn.edu).
Due date: The final grade
and report must be submitted no later than the last day of final exams
during the semester the student is enrolled. Note that a final grade
will NOT be assigned for the course without submission of the report.
Format: The first page of all
reports must contain the student's name and ID number, the advisor's
name, the enrollment term covered by the report, and a summary of the
work completed that does not exceed 1-page. This page should
be formatted with a 12-point font and have 1 inch margins. The
format for the balance of the content, including the length, any required
sections, and referencing, is left entirely to the discretion of the
faculty advisor and should be made clear to the student at the outset
of the semester. This content should fulfill the writing intensive
requirements of the course.

1. Brief statement of your research specialty: Analytical chemistry,
chromatographic analysis, biotechnology, environmental chemistry and
environmental analysis.
2. Brief statement of the type of problem(s) you would consider appropriate
for undergraduate participation:
Development of high selectivity carbon phases for HPLC analysis of environmental
samples. Due to the large number of species present at trace (ppb) levels
in typical environmental samples, there is a pressing need in environmental
analysis for highly selective analytical techniques. We are currently
working on the development of novel reversed-phase liquid chromatographic
(RPLC) supports which use chemical vapor deposited carbon on porous zirconia
as the stationary phase. These materials have two major advantages compared
to other types of RPLC supports: they are extremely stable towards acid,
alkali, and organic solvents, and they offer very high selectivity in
the separation of many types of nonpolar and polar species such as polychlorinated
biphenyls. We are currently exploring the utility of these stationary
phases for use in preconcentration of priority pollutants such as phenols
and for the analysis of pesticides, herbicides, fungicides and their
metabolites in water.
Study of solubilization in supercritical carbon dioxide. Interest in
the environmental applications chemistry in supercritical fluids is burgeoning.
Because carbon dioxide is cheap and nontoxic, it is attracting a great
deal of interest as an environmentally friendly medium for chemical processing
in place of toxic and hazardous solvents such as polychlorinated organics.
In addition, there is a tremendous interest in the use of supercritical
fluids in remediating contaminated soil. In order to use supercritical
fluids as reaction media or as extractants it is important to understand
the nature and strength of intermolecular interactions between dissolved
species and the fluid media. We are studying such interactions via supercritical
fluid chromatography as a model system. We are using the solvatochromic
linear solvation energy relationship methodology of Kamlet and Taft that
has been so successfully applied to the study of conventional liquids.
Study of quantitative structure activity relationships in environmental
model systems. The equilibrium constant governing the distribution of
a species between octanol and water (Ko,w) has been found to be extremely
useful for correlating and predicting toxicity of pollutants towards
various test organisms and in predicting the transport properties of
pollutants. We are interested in understanding the intermolecular interactions
that take place in water and in water saturated octanol so that we can
better predict toxicity and transport. Recently, we showed by use of
head space gas chromatography that the nearly 0.30 mole fraction of water
in octanol at saturation has virtually no effect on species dissolved
in the octanol. We are currently exploring the nature and strength of
the nonpolar (London) and polar (dipolar, and hydrogen bond donor/acceptor)
interactions that control the Ko,w.
