Show moreZnO 3D nanostructures composed of an array of 1D nanowires and 2D nanowalls were synthesized by chemical vapor deposition (CVD) method on c-plane GaN epilayer covered sapphire substrate. The nanowire growth followed vapor-liquid-solid (VLS) growth mechanism and the nanowall growth followed vapor-solid (VS) growth mechanism. The substrate was covered by 5 nm Au film deposited by thermal evaporation. High purity ZnO powder and oxygen were used as the source materials and argon as carrier gas. The growth temperature was 900 C. The nanostructures grew vertically along polar c-plane orientation. The field emission scanning electron microscopy (FESEM) show the top view of the 3D nanostructures. The image was taken at Swagelok Center for Surface Analysis of Materials (SCSAM) at CWRU.

Show moreVertical ZnO 3D nanostructures were synthesized on Au covered c-plane GaN epilayer film on sapphire substrate by chemical vapor deposition method. The growth was conducted in a horizontal tube furnace with 1" diameter quartz tube. High purity ZnO powder and oxygen were used as the precursors. The growth was carried out for 1 hr at 900 C. The growth direction was polar. The image shows the 20 degree tilted view of the nanostructures. The image was taken at the Swagelok Center for Surface Material Analysis (SCSAM) at CWRU.

Show more"A digital photograph of the Galaxy Messier 101 (also known as the Pinwheel Galaxy), constructed over the course of three (non-consecutive) years using the Burrell Schmidt Telescope at Kitt Peak National Observatory. The galaxy was imaged four times, using four different color light filters: a filter that isolates mostly blue light, one that isolates greenish light, one that isolates mostly red light, and one that isolates a very specific kind of red light emitted mostly by newborn stars. Each of the four images contains around 20 hours of total exposure time. This color image of the galaxy was constructed by layering five different images: the red, green, and blue filter images to create an approximately true-color picture of the galaxy and surrounding environment, an image in which the newborn stars were isolated from the background starlight (seen as the pockets of red throughout the galaxy's spiral arms and elsewhere), and an image of the galaxy that has been heavily processed in order to bring out the faintest starlight at the galaxy's edges (seen as the faint blue 'halo' of light surrounding the galaxy). The latter contains stars that were most likely torn away from the Pinwheel through gravitational interactions with one or more of its neighbors (possibly the smaller galaxy seen near the bottom of the image), and even some very young stars that may have formed through the collapse of extended gas and dust (not pictured) caused by the interaction. The faintest light seen in this image is 1000 times fainter than the dark night sky. Observations of M101 were done by the following people: Chris Mihos, Paul Harding, Craig Rudick, John Feldmeier, Chelsea Spengler, and Aaron Watkins."

Show moreThis is one transverse section of a wild type, or genetically "normal," rodent spinal cord I imaged at 16x magnification and presented in nine screens, à la Warhol. The spinal cord section was originally stained using a technique called 'Immunohistochemistry' to look for a subpopulation of neurons that express the neurotransmitter serotonin. I then used Photoshop to artificially color the sections and to hand draw the supporting cells as well as the many possible neural connections it's able to make. The intent of this piece is to show how incredibly important the use of colors are to neuroscientists. We use colors to identify and highlight important players involved in Central Nervous System physiology with the expressed purpose of finding out where these important players are, when and how they interact with themselves as well as other neurological elements in vivo. Using an array of colors bound to specific proteins, we can therefore begin to elucidate certain aspects of how our Central Nervous System works.

Show moreCan a computer algorithm recognize the hand of an artist? "Untitled 5" was hand drawn using Adobe Photoshop by my former graduate student Katherine Jones-Smith to investigate this very question. An article in the prestigious scientific journal 'Nature' claimed Jackson Pollock's drip paintings were fractal and had a distinctive fractal signature that could be used to authenticate Pollock's work. That claim unravelled when "Untitled 5" was found to be an authentic Pollock according to the fractal criteria. As a result "Untitled 5" has appeared in a publication in 'Nature,' in newspapers around the world and in a textbook on Chaos theory (but not yet in an art gallery). Meanwhile the answer to the question posed above: not yet.

Show moreI was walking along the path around the duck pond in front of the Cleveland Museum of Art, looking to capture life along with other plants and flowers. I came upon this interesting object hanging from the tree. The flash really helped to lighten up the entire composition.

Show moreTransformation Robe was inspired by a Turkish, talismanic shirt painted with magic symbols and prayers to protect the Sultan from harm. In my garment, the found text from self-improvement tapes serves a similar function in transforming the wearer. I used FreeHand to manipulate text blocks to fit into an Islamic pattern and then printed the pattern on silk organza with a photo silkscreen.

Show moreWhat is shown in the image is a billet of aluminum that has been machined using modern CNC (computer numerical control) practices. It was designed using SolidWorks, a particular CAD (computer-aided design) software suite. In another piece of software, MasterCAM, this digital model was converted into a language interpretable by the Haas vertical end mill used to machine the final piece. Subsequent to machining, it was painted and buffed before inserting the tiny ball bearing and attaching the acrylic face. The opposite side actually has a maze, so the ball can travel between the two faces via the centrally located through hole.

Show moreHigh internal phase emulsions (HIPE) are materials with incredible microscale morphologies. They normally exhibit a pore like structure with polymerized scaffolding surrounding spherical voids. This portion of the sample was somewhat different however, it illustrates how the structure changes under deformation and how the polymer reacts to non-reversible strain. This image was taken using a scanning electron microscope (SEM) with a sample sputter coated in a fine layer of gold. Gold makes the sample conductive so that it may scatter incoming electrons from a concentrated electron beam to a detector thus creating an image.

Show moreThe intended artwork is not the submitted compiled photographs, but it is the subject of the photographs instead. The sculpture is a laptop computer made out of LEGO pieces, approximately 1,000 - 2,000 pieces. Its dimensions are a 27 centimeter width, 37.7 centimeter length, and 3.9 centimeter height. In the photograph of the top left corner, the artwork (right) is compared to its model, a Windows 7 home use laptop. I managed to create the artwork by using the model and observing some of its key features. Originally, the artwork was meant to be a replica of the model, but a lack of maroon LEGO pieces allowed for creative liberties. The artwork's labeled keyboard (bottom left and bottom right photographs) lies just beneath the artwork's main attraction: the screensaver. The "opened" artwork (top center photograph) shows off its screensaver: the logo of the laptop's Internet browser, Google Chrome, a variety of desktop applications, and the phrase "STEM Builds." The closed artwork has a generally white design with purple stripes and a couple of maroon stripes, reminiscent of its model's cover color. Just as I was able to build a laptop out of LEGO pieces, STEM allows people to create anything from buildings to home appliances. So, in tune with this fact, the artwork represents anyone's desire to create. I managed to build a laptop with STEM, so what will STEM help you build?

Show moreAs I looked closer at taking images of plants and flowers, I had to make sure I was choosing the right angle for taking photos of flowers, which is the biggest issue because there are so many. To be honest, I took the photo of whatever caught my eye. I wanted the picture to grasp emotion as much as possible. As I worked with other students, I found my ideas were different from others' ideas and they wanted to replicate an image they saw while I just made my own ideas. My epiphany was, if you get the right angle with the sun and with the water droplets you could get a sparkle on the flower petals. I learned when taking plant and flower photos, choosing the right angle is very difficult.

Show moreI created this image after studying about the Forensic Sciences. One of the areas of Forensics that we learned was about fingerprinting; what they look like and what they mean to us personally. This fingerprint is mine along with the story that goes with it. That's why it is personal to me and no one else. This entry won an honorable mention for the high school category.
