Fall 2015 – Summer 2016
Atom Probe Image Reconstruction (Justin Schrimmer, Sam Gardner (UW-Milwaukee), with Prof. Rebecca Willett, Prof. Dane Morgan, started 12/2015). As scientist and researchers have begun to look at materials on the atomic scale, Atom Probe Tomography (APT) has come to the forefront of material analysis. This technology allows for single atoms to be separated from its material using electric fields with laser assistance. The atoms are then collected with a detector and mass spectrometer, and relatively simple physics models used to reconstruct form where the atoms originated. However, the accuracy of this reconstruction is rather uncertain, and atom position are often about 1 nm away from their true position, making it generally impossible to identify crystal planes, dislocation, and other atomic structures. In this project, we are using informatics tools such as deconvolution methods to take APT data sets and attempt to reconstruct the original structure with dramatically enhanced resolution.
Image Quality Assurance (Andrew Duplissis, with Prof. Tim Szycykutovicz, Prof. Rebecca Willett, started 02/2016): When dealing with computed tomography, or CT, scans, often times diagnoses are based solely on how the picture is presented. If you imagine a picture as a matrix, where each pixel has a certain coordinated and a different value stored in its location, then you would see that a green pixel has a much different value than a red pixel. This same general concept applies to CT images, except instead of the number corresponding to a color, it corresponds to a number with units of Hounsfield. When using these images as diagnostic tools a change as little as 32 Hounsfield units can result in an inability to see a lesion or tumor, this project is related to this; it has a goal to be able to detect when they have acquired a poor image and tell the technician such so the scan can be redone. We will be attempting to do this from a data base of 70,000 images all labeled with high or low image quality, and all having 20+ variables associated with them. We will be starting with the 6 we think to be most important and see if we can draw up a relationship between those 6 values and whether or not the image is of high or low quality.
Ductile to Brittle Temperature Transition Shifts in Reactor Pressure Vessel Steels (Josh Perry, Henry Wu, with Prof. Dane Morgan and Prof. Bob Odette (UCSB), started 09/2015)): As steel in a nuclear reactor is exposed to neutron radiation, the crystal structure degrades in a way that makes the metal more brittle, eventually to the point that it is in danger of cracking. This process is the main limit on how long reactors can operate before they need to be decommissioned, and is dependent on a variety of factors including amount of various impurities in the steel, the total radiation exposure, the rate of exposure, and the temperature of the steel when it was exposed. We are studying a dataset with 1550 data points and 9 independent variables, using Gaussian kernel ridge regression and other informatics methods, to predict the behavior of conditions that cannot be easily explored with present experiments.
Impurity Diffusion Informatics (Aren Lorenson, Liam Witteman, Haotian (Will) Wu, Ben Anderson, Henry Wu, with Prof. Dane Morgan, started 02/2015): The goal of the project is to predict impurity vacancy mediated diffusion energy barriers in binary FCC metal systems. This is a useful quantity to consider for many materials areas, e.g., when modelling sublattice ion defects in compound semiconductors, such as P in InP, or the microstructural evolution of steels shielding nuclear reactors subject to radiation accelerated Cr and Ni diffusion. In this project, we take existing, incomplete materials data generated by first-principles ab initio computations and achieving the same outcome in orders of magnitude less time.
Optimized Compositions for Al-Based Amorphous Alloys (Zach Jensen, with Prof. Izabela Szulfarska, Prof. Dane Morgan, and Prof. John Perepezko, started 9/2015) Amorphous (or glassy) metals represent a unusual form of metals with structures that are disordered, like window glass. Metallic glasses have many exceptional properties, including corrosion resistance, elastic response, wear resistance, and hardness. However, glasses are often hard to form, requiring very rapid quenching, allowing only small samples to be made. Aluminum (Al) glasses are particularly exciting due to their light weight and low cost. Researchers have experimentally examined many compositions to attempt to find good glass forming Al alloy using, e.g., techniques such as Differential Scanning Calorimetry. This project combines the results of all these experiments and looks for trends in glass forming properties such as the crystallization temperature using machine learning models. By analyzing the trends we can determine compositions that have strong glass forming properties as well as analyze the effects of individual elements and combinations of elements on the glass forming ability.
