Image title: SEM Image of Cr Doped MnO2
Image description: Cr-doped MnO2 was synthesized by hydrothermal method. With the doping of Cr the morphology of the pure MnO2 (nanowire) changes to “Urchin” like shape for Cr-doped MnO2. This material is a precursor for the synthesis different Na based cathode material for Na ion battery.

Image Title: Petrified Wood
Image description: SEM Image taken at the Micro Nanotechnology Center, University of Louisville. Petrified wood is fossilized remains of vegetation that has transitions to stone over thousands of years. This particular piece of petrified wood was imaged for the local artist "Matt Weir" who is working on a art exhibition based around this piece of petrified wood. He is trying to show how the same object can be interpreted in many different ways.

Image description: Boron nitride nanosheets (BNNS) and poly(vinyl) alcohol 2wt.% are mixed, ultrasonicated and processed in liquid nitrogen ‘ice templating’ followed by freeze-drying at -40 oC to construct three-dimensional directed assembly composites. The layered morphology along with polymer strands connecting the BNNS sheets is apparent in falsely colored scanning electron microscopy image acquired at EMC.

Image title: We Serve Fresh Nano Rotini!
Image description:The germanium rotini we are serving is made in an electron-beam evaporator. In this high-vacuum environment, germanium is heated up by electrons, evaporated, and deposited slowly onto the ‘plates’. The rotini shape is formed by meticulously maneuvering the 'plate'. The rotini is ~1800 nm long; the thinnest part of the rotini is ~80 nm, which is 1/1000 the size of human hair! Have a ‘small’ bite and let me cook know which flavor you like the best! The nano-rotini is ‘cooked’ and characterized at Micro/Nano Technology Center (MNTC), Kentucky Multi-scale Manufacturing and NanoIntegration Node (KY MMNIN).
“Mindful of Microvilli”
Author: Sarah Elefson
NNCI KY Multiscale Core: Electron Microscopy Center, UK
Tool: FEI Helios Nanolab 660
Description: This image of microvilli, located at 75% of the total length of the small intestine in a 21 day old pig, expands knowledge about development and function of the small intestine. Focusing on changes of the microvilli, which are responsible for nutrient absorption and resulting growth, using micrographs produces a visual aid that shows physical changes during critical stages of life. Micrographs provide details of morphological changes during gut development and allows for evaluation of alternate diets or management at specific times (e.g., immediately following birth and/or weaning) to improve gut health and nutrient utilization in pigs.

Image title: United We Stand, Divided We Fall.
Image description: This image was taken at CeNSE at the university of Kentucky. It was a 3D printed multi-layered color filters. Fisher-scientific environmental scanning electron microscope was used to take the image. The image provide an insight to the abilities of two-photon lithography system (Nanoscribe) at CeNSE.
“Mindful of Microvilli”
Author: Sarah Elefson
NNCI KY Multiscale Core: Electron Microscopy Center, UK
Tool: FEI Helios Nanolab 660
Description: This image of microvilli, located at 50% of the total length of the small intestine in a pig 2 weeks post-weaning, allowed for measurements of microvilli dimensions. Subsequent calculation of microvilli dimensions, results in the amazing realization that total absorptive area is increased 120,000,000X compared to absorbing from a simple tube. Assessing the development of microvilli allows for increased understanding of nutrient absorption during a pig’s life. Micrographs provide details of morphological changes during gut development and allows for evaluation of alternate diets or management (e.g., immediately following birth and/or weaning) to improve gut health and nutrient utilization in pigs.

Image description: This image is the EDS color mapping of silver nanoparticles supported on zeolite Y. Zeolite Y is a porous material consists of SiO2 and Al2O3. In this image, each element is in a different color. Ag nanoparticles with a particle size of 5-10 nm are on the surface of zeolite Y. Silver nanoparticles supported on zeolite Y is a catalyst that can catalyze the oxidation of phenolic structures either with light or heat. Now, this catalyst is used to treat lignin, the second most abundant biomass in the world, to yield valuable chemicals.
