Later this month Northern Oklahoma section will be hosting a seminar by Dr. Mary Orna, Chemistry Professor at College of New Rochelle, on the use of Analytical Chemistry for the conservation and investigation of art pieces.
The methods of modern chemistry can be used as probes to examine the provenance and to aid in the conservation of art objects and artifacts. In addition, these methods can help enormously in clarifying the techniques by which these objects were made, in determining their content, and in dating their origins. A variety of methods will be illustrated in the examination of such materials as medieval stained glass, Middle Eastern obsidian and pottery, and 20th century art forgeries. Although such methods can give great insight into the objects in question, there are limits to such technology; these limitations will also be discussed.
DATE: Tuesday, February 21, 2017
TIME: Social hour at 6:00PM, Dinner at 6:30PM, Seminar starts at 7:30PM
VENUE: Montana Mike's Steakhouse, Bartlesville, OK
COST: Free for ACS members, $10 for guests; Attending only the seminar is free.

Northern Oklahoma is pleased to announce that the third quarter seminar speaker will be Jeff Bryan. The title of his seminar is, "Nuclear Science and Fiction in Star Trek."
|Venue||Tri County Technology Center, Wichita Room|
|Date||Wednesday, September 21, 2016|
|Cost||Free and open to the public|
|Time||Pizza will be served at 6:30 pm, Seminar will begin at 7:15 pm.|
Much of the Star Trek universe can be understood or disputed based on our current understanding of nuclear chemistry and physics. This presentation will examine "future" technologies such as photon torpedoes, transporters, and holodecks using contemporary nuclear science. We'll also boldly go where few scientists have gone before to try to understand what dilithium really is and what it does in a starship. Even if you're not a trekkie (or a trekker), don't worry, the context of each topic will be provided through video clips from the shows and movies. Engage!

From January until spring break, Northern Oklahoma ACS member Dr. Keith Lawson trained a core group of about 20 Honors Chemistry I and Chemistry II AP students to take the Chemistry Olympiad Exam. The local exam, administered shortly after spring break, consisted of 60 multiple choice questions. Congratulations to juniors Palak Sharma and Russell Drummond, and sophomore Marisol Aranda for taking second place in the local exam. Congratulations to junior Henry Williams and sophomore Kayla Hoelscher for their top scores, which qualified them to take the National Exam. The National Exam consisted of 60 multiple choice questions plus two laboratory experiments.

Northern Oklahoma ACS is pleased to announce the spring seminar event in Ponca City, OK. Dr. Ruth Ann Armitage, from Eastern Michigan University will give her talk, "Archaeological Chemistry of Rock Paintings: Radiocarbon Dating and Chemical Analysis," on Tuesday, April 26th, at Zino's Restaurant.
While still a chemistry student at Thiel College in Pennsylvania, Ruth Ann Armitage participated in an archaeological field school and confirmed her desire to combine the seemingly disparate disciplines of archaeology and chemistry. She completed a Ph.D. in Analytical Chemistry at Texas A&M University on radiocarbon dating of charcoal-pigmented rock paintings and has worked with archaeologists at historic and prehistoric sites around the world. Dr. Armitage, Professor of Chemistry at Eastern Michigan University, and her students develop mass spectrometry methods to characterize archaeological materials, including rock paintings, dyes in ancient textiles, and ceramic residues to help archaeologists understand our ancient past.
Rock paintings, or pictographs, are unique cultural remains that are difficult to place into archaeological contexts because they are not a part of the buried stratigraphic record of a site. Direct radiocarbon dating of the paint itself would ideally be used to determine their age. The paint is typically an inorganic pigment (iron oxides and hydroxides are common) presumably mixed with an organic binder or vehicle to make the paint flow and adhere to the rock surface. Dating rock art by conventional radiocarbon techniques would have required completely destroying the paintings; the advent of accelerator mass spectrometry (AMS) for direct measurement of 14C changed that. A plasma-chemical oxidation method was developed in the 1990s to selectively remove organic carbon from small samples of paintings, yielding CO2 for radiocarbon analysis by AMS. Some paintings contain easily recognized organic material, such as charcoal, but most do not. At EMU, we are using chromatographic and mass spectrometric methods to determine the nature of the organic material present in rock paintings, and using the plasma-chemical oxidation/AMS method to date them. Results of our work on paintings from locations around the world will be presented.

On February 23, Northern Oklahoma Section hosted a successful seminar event with Dr. Carolyn Fisher, Senior Scientist at Decernis. Dr. Fisher presented an overview of the bioactive components of spices and herbs, and discussed how their strong taste and anti-microbial activity interested the food industry. She discussed the health effects of the biologically active components of numerous spices, including rosemary, ginger, peppers, and cinnamon, with an emphasis on their antimicrobial, antioxidant, anti-carcinogenic and anti-diabetic activities. It was a well-received seminar by the audience consisting of over 36 people including ACS members and their family. Thank you to all members and guests who attended this presentation. Special thank you to Carolyn Fisher for a great talk.
