Carolina Science Symposium 2024 – Register Today

Mark your calendars! The Carolina Science Symposium is on November 15, 2024 and is expected to draw about 100 participants, both locally and from the surrounding region. The symposium will be held at the McKimmon Center, as it was last year. A student poster session will be held and 9 student contributed papers will be selected for oral presentations. When registering, you will be asked to indicate whether the abstract should be considered for a poster or for a talk. Over $1200 will be awarded in prizes and drawings. The registration deadline is November 5.  RSVP here.

Vacuum Technology Short Course

Join us for a Vacuum Technology Short Course on July 18, 2024 from 9:00 am to 3:00 pm at Monteith Research Center, led by the Analytical Instrumentation Facility in collaboration with the Commercial Leap Ahead Wide Bandgap Semiconductors (CLAWS) Hub at NC State. This is primarily a hands on course with some lecture time. Individuals will work on two functioning vacuum systems. Each attendee will manually remove and install components to learn practical knowledge when dealing with vacuum systems. Covered components include forepumps, turbomolecular pumps, ion pumps, thermocouple and cold cathode gauges, valves, flanges, and feedthroughs.

In addition to hands-on instruction, attendees will receive the following:

  • Digital copy of lecture materials

The course instructor will be Fred Stevie. Fred has 40 years of experience with vacuum instrumentation and is an American Vacuum Society instructor.

Register by Wednesday July 17 to attend via this Google Form:

Light breakfast and lunch will be provided for attendees, as well as complimentary parking for non-NCSU participants.

RTNN Staff Selected as 2023 NNCI Award Winners

Our congratulations go out to Amar Kumbhar and Emily Moreno-Hernandez for winning national awards from the National Nanotechnology Coordinated Infrastructure (NNCI) in these award categories: User Support (Kumbhar, T and Education and Outreach (Moreno-Hernandez).

Amar, currently a Research Associate in the Chapel Hill Analytical and Nanofabrication Laboratory (CHANL), he has provided exceptional technical support for 15 years. This support includes training and maintenance on SEM, TEM, FIB and AFM, as well as preparing samples for electron microscopy analysis. Despite being the only staff member in CHANL that manages these tools, Amar is able to provide exceptional services to a broad range of users. His broad knowledge of characterization techniques, material types, and specimen preparation techniques has enables him to interface with and provide exceptional support to a wide range of institutions and departments, thereby facilitating convergence in the RTNN. For instance, he has worked with 11 departments at UNC, including some unconventional departments such as anthropology, dentistry, geology, and dentistry. In the last four years, he has provided technical support to 16 other universities and 25 companies. In this time frame, he has supported 384 users, including 295 internal, 50 external academic, and 39 industry. In many cases, his support for users has led to co-authorship in research collaborations where he has used his expertise in electron microscopy techniques to study unique materials systems.

Emily is a Program Coordinator at Duke University’s Shared Materials Instrumentation Facility. Using her lived experience as a former science teacher, Emily has significantly enhanced our communication with and outreach to local schools. Emily’s exceptional leadership and contributions to the Duke and RTNN Outreach team over this past year has led to significant growth in the number of outreach activities and participating students, educators, and researchers. This past year Emily coordinated and participated in 62 outreach events that served over 3600 students and educators, including 26 group visits to the Duke SMIF facility, 24 visits of the SMIF Outreach team to regional schools, libraries and community centers, and 12 live virtual events. Emily manages and operates our portable SEM, used for both in-house demonstrations and off-site, to bring nanotechnology equipment directly to the public, particularly aimed at serving underrepresented, low income, and rural populations.

Keep up the good work!

Congratulations to our 2023 RTNN Image Contest Winners!

Most Stunning

Perovskite Crop Circles
Alicia Bryan, UNC-Chapel Hill

Methylammonium lead iodide (MAPbI3) perovskite deposited on a mica substrate via chemical vapor deposition, demonstrating epitaxial rod-like structures and pyramidal crystallites. Image taken on FEI Helios 600 Nanolab Dual Beam System with a surface tilt of 45 degrees.


Most Whimsical

Giant Cabbage
Jack Almeter and James Loveless, NC State University

This image depicts an overhead view of an attempt to epitaxially coalesce AlGaN over GaN ridges. Coalescence was not complete, resulting in trenches reminiscent of furrowed farmland. Rogue nucleation has occurred at one point, perhaps due to contamination or an irregularity in the pattern. This large crystallite has an organic shape, here imagined as a giant cabbage worthy of the NC State Fair. A pair of farmers, taken from “Farmer with a Pitchfork” and “Song of the Lark” by 19th century American painter Winslow Homer, marvel at the vegetable in the foreground.

Most Unique Capability

A Witness of Evolution
Kyle Pan, Duke University

This plastic sheet, with its futuristic look, is now a living canvas of our soft morphing robots’ evolution. Its journey commenced as a mere glass cover sheet in the electron beam evaporation process, during the fabrication of our soft robot’s sensing functionalities. As the design progressed, we embraced an air-pocket design, and this sheet transformed into a photolithography mask, resulting in its various patterns on the sheet. Now, as we further improved in the soft robot fabrication, this resilient sheet stands as a laser-cut mask for oxidized liquid metal, capturing the essence of progress in our research.
