Jaesung Lee, a PhD candidate in the Department of Electrical Engineering and Computer Science (EECS) who is mentored by Assistant Professor Philip Feng, received a Best Paper Award at the American Vacuum Society’s (AVS) 61st International Symposium & Exhibition, held in Baltimore in November.
In his talk, titled “Temperature-Compensated Graphene Nanomechanical Resonators,” Lee presented the first thermally stable graphene nanomechanical resonators operating in a wide temperature range, from room temperature up to approximately 300 degrees Celsius. The new temperature-compensated design applies to graphene resonators consisting of atomically thin graphene and gold electrodes. It minimizes the overall thermal expansion of the devices, making their resonance frequencies immune from temperature variations.
A group of students from Case Western Reserve University and Lorain County Community College got a bird’s eye view of campus—and an up-close look at wind energy technology—by climbing the campus wind turbine.
The joint training session between Case Western Reserve engineering students and students enrolled in LCCC’s alternative energy technology associates degree program was organized by Wind Energy Research Center Director and materials science and engineering professor David Matthiesen.

Case Western Reserve is one of two universities in the country selected to lead a $27.3 million international effort to identify the causes of a mysterious and deadly phenomenon that strikes people with epilepsy without warning.
For the past several years, federal health officials have explored ways to spur meaningful research regarding this fatal complication of the neurological condition. Known as SUDEP, for Sudden Unexpected Death in Epilepsy, it is the most common cause of mortality for individuals with epilepsy. Because those felled by SUDEP show no signs of trauma or other explanation for the loss of life, progress in understanding the causes and mechanisms of SUDEP has been painstakingly slow.
This new initiative, dubbed the Center Without Walls for Collaborative Research, requires scientists to connect with peers elsewhere in a strategic and richly interactive way.
Two recent industrial gifts have allowed Case Western Reserve University’s Swagelok Center for Surface Analysis of Materials (SCSAM) to upgrade two of its major instruments.
Lubrizol has provided $65,000 to purchase a Vantec 500 2-D area detector for the Bruker Discover D-8 X‑ray diffractomer to replace the existing 20-year-old detector, which has now become obsolete. The new detector has the high speed and sensitivity of the original, but has better resolution, a higher dynamic range, and provides cleaner, higher quality 2-D diffractive patterns.
LaShanda Korley, the Climo Associate Professor and Kavli Fellow in the Case School of Engineering's Department of Macromolecular Science and Engineering, traveled to Japan this week as a planning group member for the 14th Japanese-American Kavli Frontiers of Science symposium, sponsored by the U.S. National Academy of Sciences and Japan Society for the Promotion of Science.
Korley co-organized a session on biomimicry, from proposing and defending the topic to identifying leaders in the field, as well as coordinating logistics of the event.
