9:30 am        Prof. David Thurlow: Exploring proteins and DNA at the National Center for Biotechnology Information (NCBI)

In the past decade, there has been an explosion in our understanding of proteins and DNA, essential biomolecules found in all living systems.  Sequences and three dimensional structures are available free of charge at the NCBI website.  We will explore genes, chromosomes, introns, exons, sequence alignments, phylogenetic trees, DNA helices, ribozymes, riboswitches,  protein-ligand binding sites, enzyme active sites, and much, much more.

David Thurlow is Director of Clark University’s Medical Careers Advising Program, and a faculty member of the Carlson School of Chemistry and Biochemistry.  He teaches courses in biochemistry and molecular biology.

10:30 am      Prof. Mark Turnbull: Demonstrating equilibrium with Co(II) salts and other demos

                        The equilibrium between the [Co(H2O)6]2+ cation (pink) and its anionic counterpart [CoCl4]2- provides a simple and visual way to illustrate equilibrium and LaChatelier’s Principle.  Principles of adding/removing starting materials/products can be easily shown along with the effect of temperature on equilibrium. Participants will go through the laboratory exercise to illustrate these points.  Time permitting, we’ll also generate a couple of explosions.

                        Mark Turnbull has been a professor of chemistry at Clark since 1986 and specializes in synthetic chemistry.  He earned his BS and MS degrees from the University of New Hampshire and taught high school in Londonderry, NH from 1978-1982 before completing his Ph.D. at Brandeis.  He has been at Clark University since 1986.

11:20             Break

11:40             Prof. Sergio Granados-Focil: Chemical processes within polymers and use of everyday polymers as teaching tools

Polymeric materials are everywhere and are used in a wide variety of every day applications. Some simple polymer synthesis experiments and polymer modification experiments will be presented. These demos can be used to illustrate fundamental concepts, such as stoichiometry, bonding, solubility, entropy, etc.

Sergio Granados-Focil, Ph.D.

Prof. Granados-Focil is a polymer chemist primarily interested in studying the relationship between polymers’ chemical structure and their ionic, thermal and electronic conductivity. The results form this effort can help establish guidelines for the development of new charge transporting membranes used in alternative energy sources (such as fuel cells, lithium batteries and solar cells), actuating materials (artificial muscles) and electrochemical sensors.

12:30             Light lunch followed by NEACT Annual meeting (lunch courtesy of NEACT)


Please RSVP by Wednesday, May 4 – we need a count for breakfast and lunch.
