Joshua Smith

Chemistry

Chemistry & Biochemistry faculty Joshua Smith is a co-author on a paper with an international team working on using triplet state Baird-aromaticity in photosensitive processes. In this study triplet state Baird-aromaticity is used to stabilize the quencher molecules used in fluorescence imaging. The paper was published in the Royal Chemical Society's open access journal, Chemical Science.

Claire Till, Matthew Hurst, Ben Freiberger

Chemistry

Chemistry faculty Claire Till and Matt Hurst, along with alumni Ben Freiberger, led a paper just published in the Journal of Geophysical Research: Oceans. This paper came from their fieldwork at sea off the coast of California and Oregon, and is compares the chemical reactivity and distribution of the essential nutrient iron with a potential tool to study it: scandium

Emeritus Professors William Wood and David Largent recently published an article in the Austrian Academy of Sciences journal Biosystematics and Ecology on the crustacean-like odor of the mushroom Russula xerampelina. This mushroom has a cooked shrimp odor that gives it the common name the “shrimp mushroom.” They and mycologist Darvin DeShazer of the Sonoma County Mycological Association, identified the chemicals that are responsible for this mushroom’s odor.

Robert W. Zoellner, James M. Moore

Chemistry

Professor Emeritus Robert W. Zoellner and his former student, James M. Moore, have published a peer-reviewed article entitled, “A DFT computational investigation of mono-sila-substituted DNA nucleobases and their hydrogen-bonded Watson-Crick dimers with the parent purines and pyrimidines”:  J. M. Moore, R. W. Zoellner, Journal of Undergraduate Chemistry Research 2023, 22, 102–110.

William Wood

Chemistry

Emeritus Chemistry Professor William Wood recently published an article in the Austrian Academy of Sciences journal Biosystematics and Ecology on the oyster-like odor of the plant, Mertensia maritima.  This plant has a circumboreal oceanic distribution where it grows just above the high-tide mark, most often on exposed maritime shingle bars. Because of the smell of crushed plant leaves, it is called the oyster plant in Britain and Ireland, and oyster leaf in North America. Wood collected this plant in Homer, Alaska and is the first person to identify the chemical that gives this plant its common names.

Chemistry

Professor Emeritus Robert W. Zoellner and his former student, Tara S. Caso, have published their third peer-reviewed article, together, entitled "The DFT computational investigation of the β-sila-α-amino acids and their β-permethylsila-analogs:  Silicon-containing amino acids as a viable foundation for silicon-based life”:  T. S. Caso, R. W. Zoellner, Journal of Undergraduate Chemistry Research 2023, 22, 47–61.
