New Grant Bolsters Colgate’s Research Capabilities michael@michae… Mon, 12/23/2024 - 08:00 A grant from the National Science Foundation will bring a new field emission scanning electron microscope (FE-SEM) to Colgate University, complete with a suite of high-tech detectors that will allow for new research in geology, physics, biology, computer science, and other fields. “[The detectors] are incredibly versatile,” says primary investigator (PI) Martin Wong, professor of earth and environmental geosciences. “So many different things happen when electrons hit a surface, and you can use all those different signals to examine the composition and structure of your sample.”  The $439,805 grant is part of the NSF’s Major Research Instrumentation program. “The goal of the program is to support critical infrastructure for scientific research, but also to train students for high-level research,” Wong says. The equipment will benefit researchers throughout the central New York region as well. Wong has partnered with several co-PIs on the project, including geosciences colleague William Peck and physics professors Ramesh Adhikari and Rebecca Metzler. With a much smaller wavelength than visible light, electrons allow researchers to image vastly tinier objects than possible with an optical microscope. A researcher can get up close to see spores on a fern, hairs on the leg of a fly, nanowires that are a hundred thousand times thinner than the diameter of a human hair, or extremely small computer circuits. Adjusting the magnetic field of the scope can train the flow of electrons in a variety of ways. “You can raster rapidly back and forth across a larger sample or fix it in a single spot to analyze something on the order of nanometers,” Wong says.  Wong’s own research focuses on plate tectonics of how mountain belts form and continents split. “When rocks are hot and deep, they don’t snap or break, but they actually flow like silly putty or saltwater taffy,” says Wong, who focuses his research on an area of the American West called the Basin and Range Province. Wong analyzes samples with a special detector called an electron backscatter diffraction detector, which is able to show how crystals are oriented within it. “That tells us a lot about which directions they were stretching in, the temperatures at which they were doing that, and how deep inside the earth they were,” he says. While Wong is mostly interested in basic science behind such processes, understanding them can also aid in earthquake detection and location of rare minerals. Geology professor Peck focuses his research closer to home, examining the formation of rocks in the Adirondacks Mountains, Ontario, and New Jersey. He’ll be able to use the electron microscope to image samples with something called the secondary electron detector, which is able to display a graded map that differentiates between minerals. For a more in-depth analysis, he’ll use an X-ray energy spectrometer, which can measure the degree that the electron stream excites the atoms within a sample, emitting X-rays that provide a fingerprint of which specific elements are contained within.  Adhikari, assistant professor of physics, works with organic materials. One project, for example, coaxes amino acids to self-assemble into tiny nanotubes; another threads nanoscopic computing components into the veins of leaves. “These bio-based materials tend to absorb the electrons that fall onto them, so you don’t really see that much,” Adhikari says. That problem can be fixed by turning up the voltage of the beam, but that actually damages organic samples. The new microscope, however, can produce high-resolution images at very low voltage without damaging fragile organic components, allowing Adhikari to examine the tiny structures he is creating. Among other uses, he is embedding the nanotubes into a polyester fabric to create a hydrophobic material that can filter oil from water. The leaves can be used to create biodegradable electronic equipment.  The ability to create crisp images at low voltage is also essential for Metzler’s work. The professor of physics studies biomineralization, the process by which marine organisms create shells and other hard materials. Some of her work examines exoskeleton formation by juvenile barnacles, which can be a scant 100 microns wide. “Our current scanning microscope can’t resolve the crystals making up their exoskeletons,” says Metzler, who has previously had to make the 75-mile trip to Cornell to use its more advanced equipment. She also studies other species of clams from the Gulf of Mexico, using the X-ray spectrometer to identify elements, and the backscatter diffraction detector to examine how crystals are oriented within shells in order to examine how climate change affects the durability of shells over time.  In addition to these research applications, the microscope will be used by a variety of faculty across campus, studying everything from volcanic eruptions in the Galapagos Islands to wear patterns of tools at pre-Hispanic archaeological sites. The equipment is versatile enough that it can be used in classroom demonstrations as well as the lab, says Wong. Countless students will use it for thesis projects over the next couple decades; at the same time, exposure to the advanced instrument will help students gain experience that could help them in working with microprocessors, nanotechnology, or mining. “This is a broadly used piece of equipment with all sorts of research and industry applications,” Wong says. “Being trained on it will give students a leg up no matter what avenue they pursue.” Natural Sciences and Mathematics Research News and Updates Faculty & Staff Department of Earth & Environmental Geosciences Department of Physics and Astronomy

Colgate Students Build Community and Connections Through International Debate oaquije Mon, 12/16/2024 - 15:57 For the Colgate Debate Society, the opportunity to square off against top debaters from the most prestigious universities across the globe has become more than intellectual competition. It is a chance to build friendships and meet others from different cultures. That was one of the highlights for the Colgate squad when it competed in the Oxford Intervarsity 2024 (known also as Oxford IV), Nov. 9–10. The tournament, held at Oxford University, welcomed hundreds of students. Many came from U.S. or U.K. institutions, though various European countries and Canada were also represented. In all, 115 teams participated, including three teams from Colgate, each made up of two students. “The Oxford IV is known for being a particularly challenging tournament, mainly because of the diverse group of debaters and the complex topics that are chosen,” says team president Sophia Lee-Wlodek ’25, a biochemistry major from Los Angeles. During debates, students make their arguments using the style followed by the British Parliament. When a motion is made, one side argues in favor of it while the other opposes it. For instance, one of the topics was titled “This House Believes That Developed Countries Should Adopt a Generalist Education System Rather Than a Specialist Education System.” Other subjects covered economic matters of foreign nations, politics, and women’s rights. “Participants only have 15 minutes to prepare their speeches, and we’re not allowed to use any external sources — no books, no internet, and no AI assistance,” Lee-Wlodek said. Each team competed in five rounds against four other colleges. “We are a fairly competitive team, often being paired against some of the best teams in the tournament,” says team treasurer Boen Beavers ’26, a political science and Russian and Eurasian studies double major. “My partner and I debated against teams from Cambridge, Harvard, and Brown University.” One of Colgate’s three teams earned a first-place finish in one of its rounds. A team from Cambridge won the competition. The Colgate team prepares for tournaments by practicing two days per week, covering everything from the basics of British Parliament Debate to advanced techniques. The team welcomes debaters of all skill levels and offers opportunities for beginners who wish to compete. Alongside the Oxford IV, the team’s calendar includes the U.S. and world debate championships — Colgate will compete in the world tournament in Panama during winter break. “Spring semester, our biggest tournament, or one we focus the most on, is our home Colgate Open,” Lee-Wlodek says. “That debate is always a great opportunity for our members to learn how tournaments run behind the scenes.” Relationships formed around the world will come in handy. “Within the debate community it is easy to make friends with other students, many of whom are from different countries and cultures, academic disciplines, and walks of life,” Beavers says. “This has also allowed us to collaborate with debaters from other countries when we host our own tournament.” Campus Life News and Updates Student Left to right: Josephine DeBono ’26, Molly O'Brien ’27, Boen Beavers ’26, Bella Duarte ’28, Sam Wolff ’28, Ben Dokupil ’25, Andrew Ludwin ’27, Sophia Lee-Wlodek ’25

Francesca Zambello ’78 Announced as Colgate’s Inaugural Clifford Innovator in Residence jkellogg@colgate.edu Tue, 12/10/2024 - 10:03 Colgate will host Francesca Zambello ’78 as the inaugural Clifford Innovator in Residence in February 2025. Zambello is the artistic director of the Washington National Opera. She also served as the general and artistic director of the Glimmerglass Festival — transforming the lives of children and early career artists in all aspects of theater through her many apprenticeship programs. The Clifford Innovator in Residence is made possible through the generosity of J. Christopher Clifford ’67, H’11, Keena Clifford P’93, and Carrie Clifford ’93, and their support of Colgate’s Arts, Creativity, and Innovation Initiative. The residency will bring innovators from across different fields in the arts, entrepreneurship, pedagogy, and technology to share their knowledge and work with the Colgate community.   During Zambello’s residency she will workshop scenes from a new opera, O’Keeffe: Kiss the Sky. The opera is based on the lives of two pioneering women in the arts, American Modernist painter Georgia O’Keeffe and Mabel Dodge Luhan, a patron of the arts associated with the Taos artist colony in the early 20th century. Zambello will work with Colgate students, faculty, staff, and a team of professional artists to develop original music, text, and choreography for the new opera. Zambello’s team includes Christopher Tin, a two-time Grammy-winning composer; Jessica Lang, resident choreographer at Pacific Northwest Ballet and artist in residence at Sarasota Ballet; and Kelley Rourke, a librettist, translator, and dramaturg. Christian DuComb, associate dean of the faculty and director of the Arts, Creativity, and Innovation Steering Committee says, “Francesca Zambello is a terrific choice for Colgate’s inaugural innovator in residence. She is not only an internationally distinguished opera and theater director, but also an entrepreneurial leader in the performing arts.” He notes that Colgate students and faculty members will have the opportunity to participate in a process of collaborative creation with high-caliber professional artists and share their work with the University community. In addition, Zambello and her team will leave Colgate at the conclusion of the residency with new material for their opera, and Colgate will be credited for support in all future productions. “It’s an honor and a privilege for Colgate to be able to support this work — and for Colgate students to contribute to its development,” says DuComb.  Academics Arts and Humanities Alumni Third Century Arts Institutional News News and Updates Alumni Faculty & Staff Bernstein Hall, a hub of creativity and innovation and the anchor of Middle Campus (Photo by Bernie Freytag)
