Come Learn How Color Changed the World

A lecture by Dr. Mary Virginia Orna, “How Color Changed the World,” will be held Tuesday, September 17 at 6 p.m., in the WMU Chemistry Building, Rm. 1220. This lecture is free and open to the public!

Mary Virginia Orna, Ph.D., is Professor Emerita of Chemistry, College of New Rochelle, New York. Her academic specialties are in the areas of color chemistry and archaeological chemistry. She has twenty-one authored, co-authored or edited books on chemical education and history of chemistry to her credit. Her latest book, March of the Pigments, was published by the Royal Society of Chemistry on May 23, 2022, a direct product of the COVID lockdown. She is the recipient of numerous chemical education and service awards, the latest being the American Chemical Society 2021 Joseph B. Lambert HIST Award “for her original research in the area of color and pigment chemistry.” In 1989, she was designated the New York State Professor of the Year, and in 1994 she served as a Fulbright Fellow in Israel. Her hobby is constructing crossword puzzles; she has contributed many of these to the New York Times. She is a religious novitiate of the Ursulines of the Roman Union, and a Fellow of the American Chemical Society.

This talk is based on her popular book, “The Chemical History of Color” (Springer, 2013). Color has been an exciting and enjoyable part of human life over the years. However, the junction between color and chemistry, and color and history, is of more recent origin. The first recorded use of chemistry to manufacture a color is the stunning set of cave paintings found in the Grotte Chauvet in Southern France. This talk traces the history of color usage as a chemical endeavor from the earliest records to the present day, focusing on four major areas: fashion, pharmaceuticals, food, and fun. It is a trajectory peppered with stories to help us understand the mystery of color as a universal experience and phenomenon; its chemical history, as you shall see, even changed the course of history in the 20th century.

Bell’s Recycle-a-Poster Date Change

Please note the BELL’s Recycle-a-Poster Event DATE CHANGE to Wednesday, November 6, same place (Bell’s Eccentric Café Back Room) and time (5-9 p.m.); our speaker will be Dr. Carrie Graveel; intrigued by science starting in Junior High at Climax-Scotts, she is currently doing breast cancer research at the VanAndel Institute in Grand Rapids.

2024 Project SEED Poster Presentations

By Doug Williams

On August 23, five of our six 2024 Project SEED fellows presented posters of their summer research at a gathering hosted by Kalamazoo College (see photos). We give special thanks to Prof. Dwight Williams (Chemistry, Kalamazoo College) for organizing the event again this year. Three of our fellows are starting college this month: Ben Knight (Kalamazoo College), Reem Rasool (WMU), and Jocelyn Suranyi (Kalamazoo College), each with interests in science and health professions. They join two of last year’s fellows, Eddie Anderson and Sadaya Hamby, who are starting at Howard University and Albion College, respectively, this fall. Dorian, Mahdi, and Rowan are returning to their high schools and hope to join us again next summer to continue their research work. We congratulate all of these promising young scholars on their accomplishments and wish them well in their future work. Our ability to offer this program has become increasingly dependent on local fund raising as we continue to spend down excess reserves. Thank you to our members who have donated to this effort. Please visit our Project SEED webpage or contact me directly at treasurer@kalamazooacs.org to learn more about how to help. We cannot do this without you.

An Invitation to the Great Lakes Regional Meeting

Please continue to keep in mind the 2025 Great Lakes Regional Meeting which will be held June 4-6 in Appleton, Wisconsin. Plan to attend and to participate in some way! The organizers would be happy to hear from you in terms of your willingness to organize a symposium for their program, or to exhibit information regarding your business or school at their exposition, and to plan to present your research (orally or by way of a poster) at the meeting. Their website is https://greatlakesregion-acs.org/event-welcome/glrm-2025 and it will continue to be updated. Regional Meetings offer many opportunities for students and aspiring chemists to network with others—faculty and industrial chemists—in an environment which is usually less intimidating than a large ACS meeting. To ask any questions please send the Local Organizing Committee an email or contact the General Co-chairs, Matt Hammers and Katie McGarry.

Comments on KACS Bylaws’ Update Process

By Jake Kirkendall

KACS 2024 Secretary

The ACS Committee on Constitution and Bylaws (C&B) requested that the Kalamazoo local section update our bylaws, as they were no longer consistent with the ACS Governing Document. The current bylaws were approved in 2009, so this will be the first update in 15 years. The majority of these updates were recommended by C&B, with some changes added by the KACS executive committee.

In accordance with current bylaws, a notice was sent out to all current members on July 26 for a 30-day comment period on the updated bylaws. The concerns expressed during this period were addressed, and amends were made to the document based on this feedback.

The next steps are for these bylaws to be voted on at the September 16 executive committee meeting. If you have any further questions or objections, please contact Jake Kirkendall (secretary@kalamazooacs.org) or attend the executive committee meeting on September 16. If issues can’t be resolved at that meeting, or if it is determined that an election is needed to approve the amendments, a special election will be held. If no further objections are raised, the Executive committee will hold a vote to approve the updates and if approved they will be sent to C&B for their approval and date-stamp.

WMU to Host Seminar on Molecule Movement

WMU Chemistry Department has graciously offered to let KACS know of seminars which they will be hosting through the 2024-5 academic year, on Mondays in the Chemistry Building, Rm. 1260 at 3 p.m. Below is the abstract for the September 30 seminar by Dr. James Penner-Hahn. (Others will be featured in subsequent monthly newsletters.)

Watching molecules move: femtosecond dynamics of cobalamins

Dr. James Penner-Hahn, Departments of Chemistry and Biophysics, University of Michigan

The motion of atoms and electrons in a molecule is central to understanding its photophysical and photochemical properties. Although a variety of methods have been used to characterize excited state structure, X-ray spectroscopies (both absorption – XAS, and emission – XES) have proven to be uniquely useful in understanding excited state dynamics due to their ability to directly probe the local structural environment of metal ions. We will describe the use of these techniques to characterize a variety of vitamin B12 (cobalamin) congeners in order to investigate the structural changes that accompany the redistribution of energy following photo-excitation and to characterize how these differ as a function of axial ligation. We show how, by controlling the relative polarization of the UV-visible pump and the X-ray probe beams, it is possible to measure polarized XAS even for molecules in isotropic solution.  We demonstrate that the structural evolution of the excited molecule is best described by a coherent ballistic trajectory on the excited state potential energy surface in which prompt expansion of the Co cavity by ca. 0.03 Å is followed by significant elongation of the axial bonds (>0.25 Å) over the first 190 fs. Subsequent contraction of the Co cavity in both axial and equatorial directions results in the relaxed S1 excited state structure within 500 fs of excitation. In contrast to K-edge XAS, which is primarily sensitive to molecular structure, XES and L-edge XAS are primarily sensitive to electronic structure. We show that the combination of all 3 X-ray methods together with UV-visible spectroscopy can provide a uniquely detailed description of the excited state evolution.
