PhD Candidate Frayne Speaks on Designing Dendritic Polymers

During the Graduate Student Speaker Series talk on April 20, Stephen Frayne, a PhD candidate in chemistry, spoke on "Designing Dendritic Polymers: From Theory to Experiment." Study and application of polymeric materials spans the physical, life, and applied sciences and has revolutionized nearly every facet of modern day society: medicine, transportation, construction, agriculture, and electronics, to name a few.

Northrop Featured in Synform‘s Young Career Focus

Brian Northrop

Synform, a journal of chemistry, recently featured an interview with Associate Professor of Chemistry Brian Northrop through its Young Career Focus series. Within it, Northrop briefly discusses his research and his most important scientific achievements.

“Currently, I think the greatest impact of my group’s research is more a matter of approach than a specific result. By this I mean that we approach research projects working across each of the ‘three M’s’ of chemistry: making, modeling and measuring. This complementary blend of synthesis, analysis, and theory provides my group with a deep, fundamental understanding of the chemical reactions and processes we are interested in…

“It is my hope that our approach to research and our initial published work have laid a solid foundation for a variety of more important scientific achievements in the future,” he said.

Physics, Biology, Chemistry, Astronomy Departments Teach Fifth Graders About Science

Fifth graders from Snow Elementary School in Middletown toured Wesleyan’s astronomy, biology, chemistry, and physics departments on June 8.

Brian Northrop, assistant professor of chemistry, and Snow School students watch chemistry in action during their visit to Wesleyan. This annual program allows local fifth graders to see how science can be exciting as well as educational.

7 Faculty Promoted, Awarded Tenure

In its most recent meeting, the Board of Trustees promoted seven faculty members.

The BOT conferred tenure on Lauren Caldwell, associate professor of classical studies; Stephen Collins, associate professor of film studies; Paul Erickson, associate professor of history; Matthew Garrett, associate professor of English; Brian Northrop, associate professor of chemistry; Julia Randall, associate professor of art; and Seth Redfield, associate professor of astronomy.

The promotions are effective July 1, 2015.

Brief descriptions of their areas of research and teaching appear below.

Lauren Caldwell
Caldwell’s research focuses on Roman social history, Roman law, and Greco-Roman medicine. Her recent book, Roman Girlhood and the Fashioning of Femininity (Cambridge University Press, 2014) investigates the social pressures

Northrop Co-Authors Paper with Middletown Student

Brian Northrop, assistant professor of chemistry, is the co-author of several new papers including:

Northrop Teaches Students at Green Street about Polymers through Putty Workshop

Brian Northrop teaches a student at the Green Street Arts Center how to properly mix the putty’s ingredients.

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 of Crayola LLC.

Northrop’s workshop is funded through a 2014 Faculty Early Career Development (CAREER) award. This is the second year that he’s taught students at the GSAC.

Northrop Awarded Prestigious NSF CAREER Award

Brian Northrop

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 recognition and self-assembly, and “click” chemistry. With the CAREER Award, Northrop and his students will continue to investigate new methods for making polymers and nanoscale assemblies.

“Synthetic polymers form the basis of many of the materials we encounter every day, from plastics and adhesives to medical equipment and electronics,” Northrop explained. “One of the primary goals of contemporary polymer synthesis is to be able to fine-tune the physical properties of polymers by exhibiting precise control over their chemical structure. By developing methods that allow such precise control, researchers are able to directly influence whether a given polymer is stiff or flexible, fragile or resilient, insulating or conductive, etc.”

Much of the research in Northrop’s lab focuses on developing a thorough, fundamental understanding of how compounds known as thiols react with alkenes and alkynes.

Northrop’s Papers Published in Chemistry Journals

Brian Northrop, assistant professor of chemistry, is the author of “Experimental and theoretical studies of selective thiol-ene and thiol-yne click reactions involving N-substituted maleimides,” published in The Journal of Organic Chemistry in August 2013. Read an abstract of the paper online here.

He’s also the author of a paper titled “Discrete, soluble covalent organic boronate ester rectangles” published in Chemical Communications, the journal of the Chemical Society, in July 2013. Read an abstract of the paper online here.

Northrop’s former students, Rob Stolz BA/MA ’13 and Natalia Powers-Riggs ’13 co-authored both papers.
