Michelle Personick, assistant professor of chemistry, and her graduate student Melissa King, are co-authors of a paper titled “Bimetallic Nanoparticles with Exotic Facet Structures via Iodide-Assisted Reduction of Palladium,” published in the journal Particle and Particle Systems Characterization, Vol. 34, Issue 5, in May 2017. The research was featured on the inside front cover of the issue.
In this study, Personick and King explain how gold–palladium tetradecapods (14-pointed nanoparticles) with an unusual combination of both well-defined concave and convex facets can be synthesized by introducing dilute concentrations of iodide during nanoparticle growth. Iodide directs the formation of the tetradecapods by increasing the rate of palladium ion reduction, which is a new role for this shape-controlling additive.

Richard Winslow, the John Spencer Camp Professor of Music, Emeritus, died July 24 at the age of 99.
Winslow received his BA in English from Wesleyan with the Class of 1940, and his BS and MS from the Julliard School. He joined the Wesleyan faculty in 1949 and taught music here for 34 years until he retired in 1983. During this time, he advocated for and oversaw the establishment of Wesleyan’s renowned program in world music and had a profound influence on the lives of many students and colleagues.
His friend and colleague, Mark Slobin, the Winslow-Kaplan Professor of Music, Emeritus, said “Without Winslow, Wesleyan would never have had the visionary music department of such ambition, scope, and radicalism that it continues to enjoy. He was a kind of radical Yankee in the spirit of Thoreau and Ives. Dick was a figure from an old Wesleyan who ensured that music would have permanent prominence in a small liberal arts college, affecting the world of music in countries, institutions, and concert halls around the globe as the ‘energy’ (his favorite word) of the place radiated outward.”

In this illustration, the hairpin is highlighted in cyan. The hairpin is formed by the initiator part of a protein.
All cells — bacterial or human — secrete up to 10 or 20 percent of the proteins that they make. Human secreted proteins, for example, include components of serum, hormones, growth factors that promote cell development during embryogenesis and tissue remodeling, and proteins that provide the basis for immune cell signaling during infection or when fighting cancer.
The secretion process, however, isn’t an easy feat for cells, as they need to move the proteins across a membrane through a channel. Transport requires the formation of a hairpin, formed by an initiator protein.
In a recent study, Don Oliver, the Daniel Ayres Professor of Biology, professor of molecular biology and biochemistry, and Ishita Mukerji, the Fisk Professor of Natural Science, professor of molecular biology and biochemistry, explain the importance of where and why hairpins form and how they help proteins move across the cell.
The study, titled “Alignment of the protein substrate hairpin along the SecA two-helix finger primes protein transport in Escherichia coli,” brings together key areas of membrane biochemistry, structural biology and molecular biophysics, and has innovative applications of molecular genetics and fluorescence spectroscopy. It was published in the Aug. 7 issue of Proceedings of the National Academy of Sciences (PNAS).

In light of President Trump’s tweeted ban on transgender Americans serving in the military, Richard Slotkin, the Olin Professor of English and American Studies, Emeritus, writes in The Conversation about the long history of integrating minorities into the U.S. military.
The armed forces have long “played a vital role in shaping American social policy toward the country’s minorities,” Slotkin writes. He recalls how “fear and resentment” of African-Americans and immigrants from Asia and Europe “generated a political backlash,” resulting in oppressive Jim Crow laws and an anti-immigrant movement in the late 19th and early 20th centuries.
Then, “The crisis produced by American entry into World War I brought these movements up short. Suddenly the nation had to raise an army of millions from scratch, with the utmost speed. There was no way to achieve that goal without enlisting large numbers of African-Americans and immigrants or “hyphenated Americans,” a derogatory term for immigrants first used at the turn of the century. It was in this crisis that American leaders rediscovered the ideals of civil equality that late 19th-century ethno-nationalism had called into question.”

Peter Rutland, the Colin and Nancy Campbell Professor in Global Issues and Democratic Thought, is the author of an article, “Imagining Russia post-Putin” published by The Conversation. The article appeared in Raw Story, Houston Chronicle and San Francisco Chronicle, among other publications.
Rutland writes that Vladamir Putin is almost sure to win re-election as president of Russia in the March 2018 election. The Russian Constitution requires him to step down after two consecutive terms, a problem Putin solved in 2008 when he moved sideways to prime minister as his protege took over as president. Putin returned to the presidency in 2012.

Tyshawn Sorey (Photo by John Rogers)
Tyshawn Sorey MA ’11, assistant professor of music, is called a “preternaturally talented multi-instrumentalist who has built a career in the territory between standard definitions” in an extensive profile in The New York Times.
“In some circles, he’s thought of as a jazz drummer; in others, he fits in more as an avant-garde composer,” the article says of Sorey, who is about to release his sixth album, “Versimilitude.”
The article discusses Sorey’s background, from his modest upbringing in Newark—where his public schools offered little in the way of arts education and his father “helped foster his affinity for music”—to his study of jazz drumming at William Paterson University.

President Michael S. Roth
In light of news that the Justice Department will investigate college affirmative action, President Michael S. Roth writes in Inside Higher Ed to urge resistance to efforts to restrict affirmative action.
“Ever since the founding of this country, we have recognized that education is indispensable to our vision of a democratic society. All men may be created equal in the abstract, but education provides people concrete opportunities to overcome real circumstances of poverty or oppression,” he writes. “Promoting access to a high-quality education has been key to turning American rhetoric of equality into genuine opportunity. And throughout our history, elites threatened by equality, or just by social mobility, have joined together to block access for groups striving to improve their prospects in life.”

Five alumnae and one student are collaborating on a play that will debut Aug. 10-13 in New York City.
Resistance, written by May Treuhaft-Ali ’17 and directed by Maia Nelles-Sager ’17, is about Libby, a 15-year-old girl from Queens struggling with her weight. Everyone in her life from her mother to her “specialist” is trying to help her lose weight, but none of them seem to understand the underlying issue. When her favorite spin teacher is fired, Libby discovers that violent revenge fantasies makes her feel better. But every time she has a violent revenge fantasy, she gains 16 pounds.
“Resistance touches on themes such as weight-loss culture, female relationships, and gentrification. The cast is entirely female-identifying, as is the production team,” said Nelles-Sager, a film and theater double major.
Nelles-Sager and Treuhaft-Ali are assisted by set designer Nola Werlinich ’17; properties designer and assistant set designer Jess Cummings ’17; graphic designer Caitlin Chan ’17; and sound designer Hope Fourie ’19. At Wesleyan, Nelles-Sager directed four shows with Second Stage and wrote a playwriting thesis; Treuhaft-Ali completed a directing thesis with the Theater Department.
Resistance will be performed at the Wild Project, a theater, film, music, and visual arts venue in New York’s East Village. Showtimes are at 8 p.m. Aug. 10-12 and at 2 p.m. Aug. 12-13. Tickets are available for purchase online.
On Aug. 2, Stephen Angle, the Mansfield Freeman Professor of East Asian Studies, professor of philosophy, together with colleagues at Notre Dame and Fordham, received a grant from the National Endowment for the Humanities (NEH) to support a two-week NEH Summer Institute for college and university faculty focusing on the idea of teaching “Philosophy as a Way of Life.” Twenty-five faculty from around the country will be invited.
The award—worth $137,045—is part of the NEH’s recent $39.3 million in grants for 245 humanities projects across the country.
The “Reviving Philosophy as a Way of Life: A NEH Summer Institute for College and University Teachers” will be held at Wesleyan July 9-20, 2018.

During the fall 2017 semester, Michelle Personick will teach Nanomaterials Lab and a chemistry symposia.
Michelle Personick, assistant professor of chemistry, received a two-year doctoral new investigator grant from the American Chemical Society Petroleum Research Fund (ACS PRF) to synthesize and test new metal nanomaterials designed to make industrial chemical processes more energy efficient. Her study, titled “Tailored Bimetallic Catalysts with Highly Stepped Facets for Selective and Energy-Efficient Epoxidation and Hydrogenation Reactions,” will be supported for two years with a $110,000 award.
“Global energy consumption is steadily increasing, and the chemical industry is the second largest consumer of delivered energy,” Personick said. “The chemical industry is unique in that it uses energy resources, such as petroleum and natural gas, both as fuels to heat reactors and as starting precursors or ‘feedstocks’ for the production of chemicals and materials.”
As demand for products of the chemical industry—such as pharmaceuticals, plastics, and specialty chemicals—increases, the consumption of energy in this sector increases dramatically. Most industrial chemical processes rely on a catalyst—a substance that increases the rate of a chemical reaction but is not used up in the reaction.
The goal of the funded research is to understand how tuning the shape and composition of metal nanoparticles changes their performance as catalysts in industrially important chemical transformations. The long-term objective is to apply this fundamental understanding to the design of nanoscale catalysts which make industrial chemical reactions more energy efficient and sustainable by (1) enabling the reactions to take place at lower temperatures and/or (2) eliminating the production of unwanted byproducts, such as carbon dioxide.
Earlier this year, the Fries Center for Global Studies sponsored its annual Wes in the World Photo Contest, which celebrates the spirit of global citizenship and encourages students to reflect upon their global experiences. Photos were submitted by students and recent alumni who have studied abroad or who have a home country outside of the United States.
Selected photos are below. View all submitted photos online.
Winner, Best Photograph of Nature: “March, Lake Moke, New Zealand. That night four of my friends (Kirsten, Mel, Jo, and Caroline) and I brought our sleeping bags outside our tents while it was freezing, so that Kirsten and I could work on taking star pictures. This photo represents my life abroad, where I spent almost every weekend traveling, camping and seeing some of the most breathtaking views with amazing people.” (Submitted by Heidi Westerman ’17)
