Members of the Class of 2019 Inducted into Phi Beta Kappa

PBK

On May 25, members of the Class of 2019 were inducted into Wesleyan’s Gamma Chapter of Phi Beta Kappa Society, the oldest national scholastic honor society. The Wesleyan Gamma Chapter was organized in 1845 and is the ninth-oldest chapter in the country.

To be elected, a student must first have been nominated by the department of his or her major. The student also must have demonstrated curricular breadth by having met the General Education Expectations and must have achieved a GPA of 93 and above.

Phi Beta Kappa is the oldest surviving Greek letter society in America, founded in December 1776 by five students who attended the College of William and Mary in Williamsburg, Virginia. The emblem contains the three Greek letters “Phi-Beta-Kappa,” which are the initials of the Greek motto, Philosophia Biou Kybernetes. This essentially means “the love of wisdom is the guide of life.”

The spring 2019 inductees are:

Caroline Adams
Yulia Alexandr
Erin Angell
William Bellamy
Cara Bendich
Zachary Bennett
Chiara Bercu
Sophie Brett-Chin
Nicholas Byers
David Cabanero
Talia Cohen

Michelle Personick, assistant professor of chemistry, has been selected by the Leadership Council of the Interactive Online Network of Inorganic Chemists (IONiC) to participate in a National Science Foundation–funded study to develop, test, and refine a flexible, foundation-level inorganic chemistry course.

As a Virtual Inorganic Pedagogical Electronic Resource (VIPEr) Fellow, Personick joins 17 other inorganic chemists from across the country in a community of practice dedicated to improving student learning. The 2018 VIPEr Fellows are the first faculty who have been selected for this groundbreaking project.

The study, titled “Improving Inorganic Chemistry Education,” is being conducted with support from the National Science Foundation’s Improving Undergraduate STEM Education program. The project will use classroom observations, analysis of student work, student surveys, and faculty interviews to study how changes in the classroom affect student learning, interest, and motivation. The project also will investigate how IONiC may encourage the adoption of evidence-based classroom practices.

At Wesleyan, Personick teaches general, inorganic, and materials chemistry. Her research group focuses on developing tailored metal nanomaterials to enable fundamental research toward improved catalysts for resource-efficient chemical synthesis and the clean production of energy.

She received her undergraduate degree from Middlebury College, where she studied platinum anticancer drug analogs, and her PhD from Northwestern University, where she developed syntheses for shaped gold and silver nanoparticles. As a postdoctoral researcher at Harvard University, she studied the catalytic behavior of bimetallic nanoporous alloys.

Article by Personick, Robertson ’18 Featured on the Cover of Chemistry of Materials Journal

An invited perspective article written by Michelle Personick, assistant professor of chemistry, and Danny Robertson ’18 is featured on the cover of the Feb. 26, 2019, issue 4 of Chemistry of Materials.

Personick was invited to contribute the perspective article as part of Chemistry of Materials’ “Up-and-Coming” series of Perspectives. The series provides a place for emerging, early career scientists to discuss and provide insights into new areas of materials science, and to showcase their research accomplishments.

The perspective, titled “Growing Nanoscale Model Surfaces to Enable Correlation of Catalytic Behavior Across Dissimilar Reaction Environments,” highlights recent advances and potential future directions in the use of larger (>10 nm) noble metal nanoparticles.

Personick also created the cover graphic.

At Wesleyan, Robertson majored in chemistry, physics, and the College of Integrative Sciences. He is currently pursuing a PhD in chemistry, researching electrochemical energy storage at the University of California, Los Angeles. His research interests broadly lie in the development of fundamental structure-function relationships in materials for energy-related applications.

Personick joined the faculty at Wesleyan in 2015, and her research group focuses on developing tailored metal nanomaterials to enable fundamental research toward improved catalysts for resource-efficient chemical synthesis and the clean production of energy. She is a recipient of the Victor K. LaMer Award from the ACS Division of Colloid and Surface Chemistry and an Army Research Office Young Investigator Award.

King Coauthors Paper and Is Elected to Chair Research Seminar on Noble Metal Nanoparticles

Melissa King

Melissa King, a PhD student in chemistry, and Michelle Personick, assistant professor of chemistry, are the coauthors of a study titled “Iodide-induced differential control of metal ion reduction rates: synthesis of terraced palladium–copper nanoparticles with dilute bimetallic surfaces,” published in Journal of Materials Chemistry A, August 2018.

In this paper, King and Personick report the use of low concentrations of iodide ions as a means of differentially controlling the reduction rates of a noble metal (palladium) and a non-noble metal (copper). The iodide in this system increases the rate of reduction of palladium ions while concurrently slowing the rate of copper ion reduction, thus providing a degree of control that is not achievable using most other reported means.

In addition, last June, King presented a talk as part of the Gordon Research Seminar on Noble Metal Nanoparticles, a graduate/postdoc meeting that takes place the day before the corresponding Gordon Research Conference. She also was elected to chair the next Gordon Research Seminar on Noble Metal Nanoparticles in two years. King also received an award for her poster at the Gordon Research Conference and gave a 10-minute poster award talk to the Gordon Research Conference audience. With the exception of the poster award talks, all presentations at the Conference portion were invited talks given by faculty.

Taylor, Alumni, Students Co-Author 3 Journal Articles

Erika Taylor

Erika Taylor, associate professor of chemistry, is the recent co-author of three articles. Two publications are related to disrupting the formation of Lipopolysaccharides (LPSs), a cell surface component that is important to Gram-Negative bacteria’s ability to form biofilms and become resistant to hydrophobic antibiotics. These papers describe inhibition of enzymes from E. coli, as well as enzymes from related pathogens including Vibrio cholerae (the bacteria that causes cholera), and Yersinia pestis (the bacteria that causes plague). Understanding how enzymes can be inhibited opens up possible new strategies for fighting diseases.

The third paper builds on her prior work investigating the ways in which sucralose (an artificial sweetener known primarily as Splenda) interacts with proteins, in comparison with its natural disaccharide counterpart, sucrose (common table sugar). She and her co-authors present data showing that sucralose interacts more strongly with hydrophobic patches on protein surfaces than does sucrose, which may be part of the way in which it causes destabilization of proteins.

These papers include alumni authors Noreen Nkosana B.A. ’11, MA ’13, Daniel Czyzyk PhD ’15, Zarek Siegel BA ’16 and current student authors Joy Cote Chemistry PhD ’18, Nimesh Shukla Physics PhD ’18, Cody Hecht ’18, in addition to Taylor’s longtime collaborator, Christina Othon, associate professor of physics at Ripon College.

Taylor also is associate professor of environmental studies and of integrative sciences.

The papers are:

Synthesis, kinetics and inhibition of Escherichia coli Heptosyltransferase I by monosaccharide analogues of LipidA,” published in Bioorganic and Medicinal Chemistry Letters, 2018, in press.

The Glycosyltransferases of LPS Core: A Review of Four Heptosyltransferase Enzymes in Context,” published in the International Journal of Molecular Sciences, 2017, 18(11), 2256. This article belongs to the Special Issue Lipopolysaccharides.
