Show moreSensors are being developed to survive harsh environments, such as that found on Venus. This is a result of a stress relief mechanism in a metallic by-layer caused by the volatilization of an oxidized buried tungsten layer. The image was obtained on an Scanning Electron Microscope at the Swagelok Center for Surface Analysis of Materials. The image was artificially colored using Photoshop and a oil painting filter applied. by D. Lukco, Vantage/NASA Glenn, A. Avishai, SCSAM, and R.S.Okojie, NASA Glenn

Show morePraying mantis nymph (Sibylla pretiosa) demonstrating the cryptic effect achieved by cuticular expansions of the exoskeleton. This species lies in wait on trees and leaves for unsuspecting prey. We found this specimen imitating a leaf blowing in the wind by waving her arms and abdomen in a single direction. Taken in Rwanda, Africa 2014.

Show moreThis composite work was created first with a self-made acrylic painting that was photographed and overlaid with data (scanning electron microscope image of polymer fibers from my research project). The title "Submerge" is to convey to the audience the importance of polymer research and its effects on the environment. We are all submerged in polymers in every aspect of our lives and as a polymer researcher I hope to improve these materials to better our well-being and aid in the environmental cleanup. The fish in water was an important aspect to convey the example of being submerged. While the polymer fiber overlay acts as both a net and as pollution in our environment.

Show moreAs I was walking on the campus last year (winter 2015), disappointed with a very harsh and cold winter in my first days joining Case as a graduate student. Suddenly everything changed when it turned to a sunny day!

Show moreThis image captures the transition in time of a perovskite reaction, a material used in solar devices. The intersection of reacted perovskite, left, and unreacted tin iodide crystals in a matrix of methylammonium solution (MAI), right, highlight the process of creating perovskite, as the unreacted region on the right shows large crystals on the order of several microns decreasing in size as the crystals get closer to the reacted perovskite region on the right. Tin iodide crystals appear to burst out of the perovskite that it was made from, when in fact the two regions were spin coated 20 seconds apart, and thus could not react. From this image, we elucidate that the reaction time for perovskite formation is incredibly fast, and we are closer to understanding the mechanisms for perovskite reaction.

Show moreThis image was created using the open source code provided by Google as an initiative of their DeepDream program. DeepDream uses a convolutional neural network to find and enhance patterns in images, thus creating a dreamlike appearance in the deliberately over-processed images.[1] We used a digital image of Van Gogh's Starry Night and trained Google's code to manipulate a digital image of Taj Mahal. The algorithm runs in iterations to learn from Starry Night and incorporate the artist's style to redraw Taj Mahal. In short, the code gives an output image of Taj Mahal if it was drawn by Van Gogh! The scientific interest is in understanding the DeepDream code that works on the basis of Neural Networks and Computer Vision to train the computer and obtain an image that was produced by learning the artist's style.
