Show more"The Moment You Live" is the piece that I decided to make when I was walking in the silent woods. In the woods, if you look at the numbers on the cut out stone and binary numbers on the piece, every second you would think about humanity and nature. Perhaps you will find yourself in the moment. The piece in the photo was created by collaboration with think[box]. I cut out the sand stone with shop bot at think[box]. And they helped a lot to make this work. It was possible to make a hole in a stone because I could work with think[box].

Show moreElectron transparency of the microstructure features from a Nickel based alloy after a FIB-SEM lift out looks like a real life scene! A sheep with curly hair eating grass and living happily 20 microns deep into an oxide layer of a jet motor turbine.

Show moreNorthern Lights are magical. Unlike a revealed magic trick, the magic of Northern Lights is just as awe-inspiring even after you understand how they work. Pictured: An Icelandic church, with lit crosses bedecking its graves, sits frozen as the Northern Lights dance all around it.

Show morePolarized light microscopy of mechanically aligned, electrochemically compacted collagen. Collagen molecules are isolated from skin samples and processed into a semi-viscous fluid. This fluid is then introduced into a mold between two carbon electrodes. By applying a voltage across the electrodes, a pH gradient is formed. The collagen molecules are driven into a thin sheet or thread, which can then be used as a scaffold for cell culture studies and development of engineered tissue. These scaffolds can be stretched in order to align the molecules, which in turn will induce any cells seeded on the scaffold to align. By varying the amount of stretching, varying degrees of alignment can be achieved. In the polarized light microscopy image "Order in Organic Chaos" a partial alignment of the scaffold is presented. The blue areas indicate alignment along the diagonal of the image running from the bottom left to the top right, whereas the other shades represent localized misalignment. The elliptical shapes are the result of gas bubbles, released during electrical compaction, being trapped in the sheet. By varying the time of compaction the presence of such bubbles can be limited. And so, from a vial of randomly floating molecules, ordered structures can be formed and controlled.

Show moreThe "Owl of Knowledge" symbolizes each subject of education coming together as one. From the palette on its head to the keyboard design on its body, they all connect in different subjects that students study throughout their educational experience.

Show more"View inside a semiconductor growth vacuum chamber. The magenta glow is the result of ionized molecular hydrogen plasma that enters from the quartz tube positioned vertically at the top. When the positively charged hydrogen ions recombine with the excited electrons, light waves of this hue are emitted. The central barbell shaped crucible is filled with molten indium (In). When nitrogen gas is added to the plasma, atomic N dissolves into the liquid metal and the target material indium nitride (InN) can grow. The purpose of the design is to generate a large temperature difference from the top of the crucible to the bottom. The narrow crucible stem has a low thermal conductivity so that heat energy accumulates at the top. The two copper leads at the top of the crucible provide current to a heater. The two pincer-like probes measure the temperature at the top and bottom of the indium well. The copper base plate efficiently removes heat from the base of the crucible to a water-cooled vacuum jacket heat sink. This design generates a temperature difference of 150 degC over a span of two centimeters. The temperature at the top is too hot for InN to grow. At the cooler bottom however the growth temperature is optimum. Therefore, away from the chaotic and dynamic surface, as the dissolved N reaches the bottom, the measured growth of InN should happen from the bottom-up producing high quality material. Recommended size height=16"" and width=12""."

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.

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 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 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 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 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.
