Westmont has installed a new Nuclear Magnetic Resonance (NMR) spectrometer in the Whittier Science Building thanks to a $383,000 grant from the Fletcher Jones Foundation. The new 400 MHz spectrometer, which replaces a 300 MHz spectrometer that had reached the end of its 14-year life expectancy, allows researchers to peer into the molecular world and determine the structure of molecules.

“The chemistry department is feeling energized with the new spectrometer and a recent grant challenge match from the Stauffer Charitable Trust to endow our summer research program,” says Niva Tro, Westmont chemistry professor. “The new Fletcher Jones NMR will be an essential tool in our vital research program.”

The spectrometer is housed in the Fletcher Jones Foundation NMR Laboratory on the second floor of the Whittier Science Building. Since 1984, Fletcher Jones has given about $1.3 million in grants for other technology upgrades and research equipment, which have enhanced Westmont’s biology, chemistry, engineering and physics, and psychology departments. The foundation has also contributed $1.5 million toward the endowment of the Gaede Institute for the Liberal Arts and to establish the rotating Fletcher Jones Foundation Endowed Chair in the Social Sciences.

The Fletcher Jones Foundation was established in 1968 by Fletcher Jones, cofounder of Computer Sciences Corporation, a worldwide leader in business technology. Following his untimely death in 1972, the foundation received the bulk of his estate. The primary mission of the foundation has been and still is the support of private, independent degree granting institutions of higher education in California.

Kristi Lazar Cantrell, assistant professor of chemistry, has used NMR extensively and has published her research in scientific literature. She uses the NMR with students in organic chemistry laboratories and in her research group to check the purity of chemicals in protein synthesis and purification. Westmont obtained the previous spectrometer when Cantrell was a student at Westmont. “We used the NMR frequently in class and during my undergraduate research,” she says. “When I entered graduate school, I was able to use the NMR there with little training, and I was thankful for the time my professors at Westmont invested to teach me this invaluable technique.”

Challenge Grant from the Stauffer Charitable Trust to Support Summer Undergraduate Research

 

The John Stauffer Charitable Trust has awarded a $500,000 challenge grant to endow the Westmont chemistry department’s Summer Science Research Program. The trust will match each dollar donated to the program through 2017 until the college is able to endow the program with $1 million.

“Summer research at Westmont with Professor Allan Nishimura taught me how to be a scientist and ultimately persuaded me to pursue my doctorate in physical chemistry at Stanford,” says Niva Tro, who has been teaching chemistry at Westmont for 22 years. “Because I was included as a coauthor on three of Allan’s publications, I was able to gain admission into the best chemistry graduate program in the country.”

In Nishmura’s 31 years at Westmont, he has collaborated with about 80 different students, co-authoring 95 published manuscripts.

“The grant secures the future of undergraduate research in the chemistry department at Westmont in perpetuity,” Tro says. “We manage to scrape our program together each year, but this grant puts it on secure footing and will even allow us to expand it a bit.”

If fully matched, the grant will fund housing and stipends for eight to 10 student researchers each summer. Currently, the college has the funding for three to six student researchers. “Science is best learned through apprenticeship,” Tro says. “When students do real research in a small group with a faculty member, they experience science from the inside. That experience is invaluable.”

The John Stauffer Charitable Trust, a private foundation based in Pasadena, was established in 1974 under Stauffer’s will. The trust directs its support primarily to Southern California hospitals, universities and colleges. In recent years, the trust has emphasized grants to fund student research in chemistry and biochemistry at such colleges as Westmont, Occidental, Harvey Mudd and Pomona.

Hannah Ryan, a 2012 Student Summer Researcher in Chemistry

had these comments about her experiences working with Professor Nishimura:

My summer research experience was truly impactful .... Research opened up my eyes to a world of creative and critical thinking.

I play the violin in the Westmont orchestra, and I realized that science is a lot like music. ...[R]esearch is the composing of science. It is the artistic expression of scientific minds... questioning, discovering, creating.

Confidence in my ability to think and explore has revolutionized the way I approach academics... and also my personal life. I am more engaged in my classes, and just have a general hunger for learning.

New General Chemistry text moves quickly to the top of the class.

Niva Tro

Niva Tro, Professor of Chemistrypublished a textbook, “Chemistry: Structures and Properties” (Pearson). Pearson is also releasing the fifth edition of his book, “Introductory Chemistry,” with an eText. Michael Everest (chemistry) developed a companion workbook for the textbook.
Niva Tro loves teaching chemistry, but he wasn’t satisfied with the textbooks available for college courses. So he started writing his own. His first venture, “Chemistry in Focus: A Molecular View of Our World” (Thomson, 2001), has reached its fourth edition. Students at more than 70 colleges and universities use the book in classes for non-majors. Emphasizing the role of the molecular world in daily life, Dr. Tro demonstrates the relevance of chemistry by covering issues such as global warming, acid rain and drugs.
The success of this book encouraged Tro to produce a second work, “Introductory Chemistry” (Prentice Hall, 2006). In use at more than 220 institutions, the text is the best-selling volume for preparatory chemistry. He discovered the need for such a book when he taught at Pepperdine; Westmont doesn’t offer this kind of class. As he did in the earlier book, Tro ties chemistry to current events and helps students understand the value of mastering scientific concepts. Clear writing and clever graphics make the text appealing .“Chemistry: A Molecular Approach” (Prentice Hall, 2008) was released in the spring of 2007, the text drew strong and immediate interest. Tro attempts to meet the needs of both faculty and students by covering complex material in depth while striving to make it as easy as possible to grasp. “I set the bar high and then gave students a lot of help in mastering the content,” he says. “With support, they can reach a higher level of understanding.”
