On Nov. 3, Brian Northrop, assistant professor of chemistry, spoke to students at the Green Street Arts Center about polymers. As part of the hands-on workshop, Northrop taught the participants how to make their own silicone polymer putty with glue, water, Borax and food coloring. Similar putty was accidentally invented during World War II when an American scientist working for General Electric in New Haven, Conn. was trying to create synthetic rubber using silicone oil and boric acid. The result produced a "solid-liquid" goo that had a high melting temperature, could bounce when dropped, and stretch. The product is most commonly known as Silly Putty, a trademark…

Two graduate students and two faculty attended the 248th national meeting of the American Chemical Society Aug. 10-14 in San Francisco, Calif. Chemistry graduate students Duminda Ranasinghe delivered a poster presentation on her research titled "Efficient extrapolation to the (T)/CBS limit" and an oral presentation on "Density functional for core-valence correlation energy." Chemistry graduate student Kyle Throssell presented two poster presentations on "Potential curves of selected radical thiol double additions to alkynes" and "Assessing weak interactions in small dimer systems with PM7." The students were accompanied by George Petersson, the Fisk Professor of Natural Science, professor of chemistry; and Michael…

Fifth graders from Snow Elementary School in Middletown toured Wesleyan's astronomy, biology, chemistry, physics and scientific imaging departments on June 18, 2014. Students also visited the Joe Webb Peoples Museum and Collections in Exley Science Center. (more…)

This summer, Elaine Tsui ’15 will work on her undergraduate research in the Chemistry Department as an American Chemical Society Fellow. Tsui, who is double majoring in English and chemistry, received the fellowship from the Society's Connecticut Valley Section. Funding opportunities are available for those with interests in physics, biology, materials science, engineering and medicine. As a fellow, Tsui will conduct self-directed research under the supervision of Albert J. Fry, the E.B. Nye Professor of Chemistry. In 2013, Tsui worked with Fry as a Hughes Fellow and studied “Andodic Oxidation of 1,1-Diphenylacetone in Various Alcohols." She will continue this research for 10 weeks…

This month, the National Science Foundation awarded Brian Northrop, assistant professor of chemistry, with a 2014 Faculty Early Career Development (CAREER) award. The CAREER awards support junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations. The honor came with a five-year grant totaling $537,561, which Northrop will use on his study titled "Selective Thiol-Ene and Thiol-Yne Chemistry, From First Principles to Organic Materials.” At Wesleyan, Northrop's research focuses on the design, synthesis and analysis of new organic materials utilizing molecular…

On April 18, the chemistry majors group, Free Radicals, performed some of their favorite chemical demonstrations. The audience enjoyed liquid nitrogen ice cream afterwards. Photos of the event are below: (Photos by Ryan Heffernan '16) (more…)

Erika Taylor, assistant professor of chemistry, assistant professor of environmental studies, delivered the keynote address at the 16th Annual Undergraduate Research Symposium, hosted by the School of Natural Sciences of Fairleigh Dickinson University on April 25. Taylor spoke on "Alternative Energy Sources: Enzymology That Is Essential for Making Lignin." At Wesleyan, Taylor is exploring the enzymology that is essential for making Lignin a viable biomass source for production of energy and as a commodity chemical feedstock.

Several graduate students and faculty from the Molecular Biology and Biochemistry Department, Chemistry Department, and the Molecular Biophysics Program presented their research at the 2014 Annual Biophysical Society meeting in San Francisco, Calif. Feb. 15-19. The Biophysical Society encourages development and dissemination of knowledge in biophysics through meetings, publications and committee outreach activities. Every year, the society holds an annual meeting that brings together more than 6,000 research scientists in different fields representing biophysics. (more…)

David Westmoreland, associate professor of chemistry, and chemistry graduate student Breanna Craft presented a paper titled, “pH-Dependent Mechanisms of 1H Relaxivity in a Series of Structurally Related Mn(II) Cyclen Derivatives” at the 245th National Meeting of the American Chemical Society held in New Orleans, La. in April 2013. Westmoreland, Craft and chemistry graduate student Sarah Hensiek also presented a paper titled, “Solution Dynamics of Transition Metal Complexes of Cyclen Based Ligands Containing Amide and Carboxylate Functional Groups."

Brian Northrop, assistant professor of chemistry, and chemistry graduate student Merry Smith are the co-authors of "Discrete, Soluble Covalent Organic Boronate Ester Rectangles,” published in Chemical Communications, 49, pp. 6167-6169 in 2013.

Erika Taylor, assistant professor of chemistry, assistant professor of environmental studies; Manju Hingorani, professor of molecular biology and biochemistry; molecular biology and biochemistry graduate student Shreya Sawant and chemistry graduate student Daniel Czyzyk co-authored "E. coli Heptosyltransferase I: Exploration of Protein Function and Dynamics" published in Biochemistry, 52, 5158–5160 in 2013. They presented the paper at the 23rd Enzyme Mechanisms Conference held in Coronado Bay, Calif. in January 2013 and at the 57th Biophysical Society Conference held in Philadelphia, Pa. in February 2013.
