complete experimental work for Maingroup atmospheric gases

There is an interesting Seminar in Laney 103 at 1:40 pm today.

 

         Title = “Ozone, PAN, and Aerosols in Megacities: Mexico City MILAGRO”

 

        Jeffrey S. Gaffney

        Professor and Chair

        University of Arkansas at Little Rock

 

        Air Pollution has been known for some time, having been termed   "photochemical smog" in Los Angeles and the Soutwest Coast Air

        Basin in California during the early 1950s. A brief overview of the chemistry of smog and its connections to peroxyacetyl

        nitrate (PAN) will be given. A novel measurement approach for PAN using luminol chemiluminescent detection and fast gas

        chromatography will also be discussed and compared with the  conventional electron capture detection method. PAN connections

        to aerosols and aerosols impacts on climate will be made during the presentation, and the current aerosol links to climate

        change made. A field project in Mexico City that was just completed in March of 2006 will be described and the use of

        natural radionuclides to evaluate aerosol lifetimes, sources, transport, and removal discussed briefly. The MILAGRO project is

        a combined effort of over 400 scientists from the U.S., Mexico and Europe and was supported by the Dept. of Energy, NSF, and

        NASA as well as Mexican agencies.

10:30 am Course evaluations administered by Dr. Felling.  I appreciate your objective feedback on the course re. things you appreciated and ways to improve.  Realize that these evaluations are completely anonymous; all written comments are retyped, so that I do not see the handwriting.  I also will not see these until late January, so they cannot positively or negatively affect your grade.  I especially appreciate constructive written comments, as the bubble sheet questions provide just numbers but no specifics.  Given the short class time allotted to this, you may wish to write your written comments before class and then give them to Dr. Felling when he comes to evaluate the course for me.

Faculty leading the 2007 Summer study abroad trips as well as past student participants will be on hand to answer questions about each trip. Brochures covering schedules, credit and costs will be available. Representatives from the Office of Financial Aid and Office of Study Abroad will also be present to answer any study abroad related questions.

In addition to the summer study abroad programs, information will be available for UCA’s summer language immersion programs, semester exchange programs and other affiliated programs. For more information contact Danielle McGhee, Director of Study Abroad, at 450-3445 or dmcghee@uca.edu.

Call for volunteers!!
We need all the help we can get to make this year's National Chemistry Week at the Museum of Discovery a success.  I have been given your name as someone who has participated in the past or who might be interested in participating this year.  Feel free to forward this to anyone that might be willing to help out.
We will have 4 tables set up with activities for the kids to participate in.  We need volunteers to man the tables and help the kids with the activities.  We need volunteers for Thurs. Oct. 19, Fri. Oct. 20, and Sat. Oct. 21. 
If you can't help man the tables on that date, we also need a couple of groups to make some interactive displays related to the theme, Chemistry in the Home.  I have some ideas or you can come up with your own idea.
Please fill out the form below to volunteer.  The more volunteers we can get the less work and more fun it is for each group.

It is important to wisely use the five days that pass between Thu and Tue lectures.  During this period you should complete all assigned reading and homework problems so that when you return to lecture on Tue you are fully prepared to participate in that day's lecture.  It is unlikely that you will do well on time exams and quizzes if you do not make effective use of this interim period of time.

 

It is often the case that many are rusty with electron configurations.  This is to be expected since you've not done them in a while.  It is important to realize, however, that we will not spend a great deal of time in class reviewing such concepts from Chem 1450 and 1451.  For this reason I put together the review homework assignment.  It is designed for you to seriously consider important tools from Chem 1450 and 1451 and to be motivated to get back up to speed now as opposed to playing catch up during the semester; there isn't time to play catch up as the semester progresses.  Do not just try to get answers for the review homework.  Try to re-master these essential tools from the past. Your success in this course depends on it.  Feel free to use my office time if you have any questions about this assignment.
