Join us for a special Take-out Science Session as we celebrate National Nanotechnology Day on October 9th. We will give a quick introduction to length scales and nanotechnology, find out more about a clean room, and observe various samples on our scanning electron microscope. We will go live at 1 pm (EDT). Submit your nano-inspired questions for our experts in the comments section below or email us at email@example.com.
In honor of National Nanotechnology Day, the RTNN and NNCI are supporting the second annual “Plenty of Beauty at the Bottom” image contest. Do you have an image that you think could win most stunning, most unique, or most whimsical? If so, learn more and submit your image at the Image Contest Website. The deadline for image submission has been extended to September 18, 2020. Check out last year’s winners here.
A big thank you to everyone who submitted an image in the 2019 Image Competition. We are excited to announce the winners. Please vote for these amazing images in the NNCI Image Contest, There’s Plenty of Beauty at the Bottom. Voting will open on October 7th!
Gill raker of the Japanese medaka
Melissa Chernick, Duke University
This image shows a portion of a gill raker from a Japanese medaka (Oryzias latipes), a small fish often used as a research model. Gill rakers are tooth-like structures inside a fish that help capture prey and prevent damage to its gills. The image shows some of the tissue that makes up the gill raker: a taste bud surrounded by pavement cells.
Most Unique Capability
Nanocoined Structures in Diamond
Nichole Miller, Smart Material Solutions, Inc.
This image shows hierarchical features that were milled into diamond using a focused ion beam. This patented process, “Nanocoining,” can seamlessly nanopattern drum molds for roll-to-roll manufacturing hundreds of times faster than competing technologies. This enables nanopatterning that was previously feasible for only small, academic experiments to be applied on the industrial scale. Nanocoining opens the door for nanostructured surfaces with unique optical and wetting properties to be applied to a variety of commercial products including OLEDs, biosensors, wire-grid polarizers, solar panels, and windows.

Particulate matter (PM) refers to liquid or solid particles suspended in the atmosphere and comes from dust, combustion by-products, exhaust, fires, and even vegetation. When PM deposits on the surface of solar panels, it can reduce energy production by up to 40% resulting in ~10 to 50 billion dollars of annual losses globally. Scanning electron microscope (SEM) images of particles on the panel surfaces help us to better understand the sources impacting soiling. This piece of dust reminded our group of a flower, seemingly blooming out of an unearthly field. Even at this tiny scale, we can find familiarity.
The RTNN and NNCI are supporting an image contest this month in honor of National Nanotechnology Day. Do you have an image that you think could win most stunning, most unique, or most trompe-l’oeil? If so, learn more and submit your image at the Image Contest Website. The deadline for image submission has been extended until September 25, 2019.
On October 13th, RTNN honored National Nanotechnology Day at the Chapel Hill Public Library. Visitors were invited to explore science at the nanoscale by participating in a variety of hands-on activities. Library patrons tried on clean room suits, made “nano” ice cream, designed photomasks, examined samples with light microscopes, and more! Participants and volunteers had a blast celebrating the nanometer and learning from each other. The RTNN will return to the library in April 2019 with a scanning electron microscope in tow during the North Carolina Science Festival.
