MATERIALS VISUALIZATION COMPETITION (MVC)
MVC is a scientific visual and artistic competition sponsored by the Department of Materials Science and Engineering and the Materials Research Institute. Created to celebrate the quality of research in Materials at Penn State, this competition promises to increase awareness of materials science through the creativity and visualization of our researchers.

| These little mushroom clouds were created from a Q-switched ultraviolet laser at the Applied Research Laboratory’s Laser Processing Division. When focused onto a material, this intense burst of laser energy creates a power density (irradiance) of almost ten trillion watts per square centimeter. Almost no material on earth can withstand this intensity, and causes explosive vaporization and plasma formation. This image shows approximately 10 mm tall plumes that have developed into the familiar mushroom shape because of the creation of high temperature, low density gas. In this image, the pulses were produced at a rate of 1kHz and quickly scanned across a paper surface to display the evolution of the resulting plumes. | ||

| The sample is an in-situ TiO2/Polystyrene composite made by polycondenstation reaction of TiO2 precurser (TiBuO4) and water in Polystyrene solution in 60°C. After TiO2 particles are made in polymer solution, the solution is casted into a film and dried. The image is taken from the fractured surface of the film after breaking it in liquid nitrogen. The image clearly shows the advantage of in-situ technique in achieving individual dispersion of TiO2 particles in the matrix. By controlling reaction parameters like PH and temperature, size of the individual particles can be changed from micron to nanomaters. In this sample weak interfacial interaction between TiO2 particles and Polystyrene matrix is the reason of separation of some particles from the matrix at the time of fracture and the resulting holes left from places, particles have been located before. TiO2 in particle shape can be used to improve dielectric properties of polymeric matrices. | ||

| This colorized transmission electron micrograph of a boron carbide (B4C) titanium diboride (TiB2) directionally solidified eutectic shows many important features of the as-grown in situ composite. The light (orange colorized) phase is boron carbide, which shows twinning throughout, represented by the sharp, angular lines of contrast near the top and center of the image. The twin lines are angularly separated by approximately 65 degrees, corresponding well to the definitive angle in the rhombohedral B4C crystal structure. Additionally, strain contrast can be seen throughout the B4C matrix, and specifically between the two TiB2 lamellae at the left center of the image. The strain between lamellae is due to differences in coefficient of thermal expansion, and the contrast in the TEM image can be correlated directly to tensile residual stress fields in B4C, caused by residual tension parallel to the long axis of the TiB2 lamellae. Image is 3.5 µm in width. | ||

A linear array of xylophone bar type transducer was fabricated using PbZr0.52Ti0.48O3 (PZT) as the activepiezoelectric layer. Similar fabricated transducers have 63MHz center frequency and 30 % of 6dBbandwidth. The resulting PZT linear array is compatible with low‐voltage CMOS (<3.3 V) and we havedesigned and fabricated a fully integrated CMOS transceiver chip to interface with the transducer array. The process of these structures involves:
