NUANCE Center Fall 2015 Image Gallery


We received very impressive images for the NUANCE Center Image Gallery Contest - Fall 2015. Thank you to all who participated! 9 images were chosen and this album contains the grand prize winner and 8 honorable mention winners.


 You are cordially invited to the
NUANCE Center Image Gallery Reception
Monday, January 11, 2016
3:00-4:00pm
Cook Hall 1st Floor Atrium (2220 Campus Drive, Evanston)
 

See the winning images, and learn about the science behind each image!

At the reception, we will award the prizes to the winners (One Grand Prize - $100, Eight Honorable Mention prizes - $25)! ALL image contest participants will also receive a special prize. We look forward to seeing you there!

The winning images will be displayed in the Cook Hall, 1st floor atrium during the reception, then in the NUANCE Image Gallery, which is located in the 1st floor of Cook Hall, east side of building. The images will also be posted on our NUANCE website and our social media pages.

Pizza, Pop, and Treats will be provided!!

“Metropolitan at sunrise”


IMAGE: This is a false color SEM image of CaCO3 polycrystals composed of many rhombohedral calcite crystallites. The hierachical arrangement of calcite crystallites resembles a futuristic metropolis at sunrise. With each color being its own crystallite buillt on each other like skyscrapers stacking to the sky. Taken with the Hitachi S4800 SEM in the NUANCE, EPIC Facility.

“Nightmare”

IMAGE: This image was taken when Ran conducted in-situ heating TEM experiments. The material she used is ZITO30(In1.4Zn0.3Sn0.3O3). The hexagonal shape appearing in the images are actually the nucleation phase while the gray area is amorphous area. The black and white contrast in the nucleation area are bend contours, which are caused by the bending of the materials during heating process. She give the name of nightmare just because when she painted it with colors, it looks like one of the images appearing in her dream. Taken with the Hitachi 8100 TEM in the NUANCE, EPIC Facility.

“3D Printed Stent”

IMAGE: False colored SEM micrograph of a biodegradable polymer stent. The stent was 3D printed using layer-bylayer curing of a citric acid based elastomeric polymer by exposure to UV light. Each layer is 20 micron as clearly visible in this image. Taken with the FEI Quanta ESEM in the NUANCE, EPIC Facility.

“Sticky Nanofibers”


IMAGE: These are nanofibers designed to mimic the chemical structure of heparin. Heparin binds to growth factors, and by mimicking it's chemistry we have created nanofibers that can similarly bind to growth factors. The surface of these nanofibers is so sticky that they seem to be sticking to each other when viewed under the SEM. This material is designed to be an injectable delivery vehicle for growth factors which will slowly release bound proteins at a controlled rate. Taken with the LEO Gemini 1525 in the NUANCE, EPIC Facility.

“NanoNebula”

IMAGE: Although a decillion (10^33) times smaller and a quadrillion (10^15) times faster, the formation of BaCO3 bears a striking resemblance to a supernova. A rapid burst of precipitation creates whisps ion-rich material that grow up to 1 micron (10-6 meters) in diameter before collapsing into a denser and more stable particle. While the nebulae created by supernova explosions exist for billions of years, these precipitates only last for a few seconds. Therefore, they must be plunged into cryogenic fluid to freeze them in place. The result is a 'quenched explosion' of the NanoNebula seen above. Taken with the Hitachi HD2300 STEM (cryo mode) in the NUANCE, EPIC Facility.

“Split Woman”

IMAGE: This is a metal alloy of cobalt, chromium, and molybdenum. The metal sample is thinned to 100 nm thick and then imaged using transmission electron microscopy. The white contrast is the background from the vacuum. The sample is false-colored pink, with the black lines are from bending in the sample. The sample was made using the FEI Helios Nanolab Dual Beam SEM/FIB and imaged using the Hitachi H-8100 TEM.

“NanoRing Nebula”

IMAGE: The gold nanorings and nanospheres were synthesized separately, but they could be brought together by DNA-mediated assembly. The inner surface of the nanoring is selectively functionalized with a certain DNA, and DNA with complementary sequences covers the surface of the nanosphere. Subsequently, the cooperative hybridization of the DNA guides the sphere to get stabilized at the center of the ring. Image is false-colored to resemble "Ring Nebula," a famous deep-sky object. Scale bar: 50 nm. Taken with the Hitachi HD-2300A S/TEM in the NUANCE, EPIC Facility.

Prospecting

IMAGE: Collection of Au nanoprisms and nanoparticles linked by DNA and deposited on a TEM grid. The overlapping nanoprisms show moiré finges. Taken with the Hitachi HT7700 S/TEM in the NUANCE, EPIC Facility.
