We propose to modify a commercial DIC microscope for operation in the deep UV region (e.g., 254 nm). At these shorter wavelengths, the diffraction limit is already half of that in the visible region. One would expect the resolvable dimensions to be proportionally smaller. More importantly, UV light approaches the absorption bands of most common chemical species. The well-known Kramers-Kronig relationship predicts that the refractive index of the species will increase substantially near an absorption band.

Energetic calculation is one of the most important tools used in alloy design and optimization. The computations based on energetics for both equilibrium and non-equilibrium phase transformations will be used to develop new alloys and processing. Students will use thermodynamic theory to describe the properties of alloys. The internship will include calculation program development for ternary or multi-component systems using C++.
Mentor: Shihuai Zhou, Assistant Scientist III, Ames Laboratory
Blood is a common type of evidence found in violent crime scenes. The location and patterns of bloodstains are often used to confirm or refute suspect or witness accounts of the circumstances or sequence events related to a bloodletting incident. Given the complex nature of both real world environments and the fluid itself, a fundamental understanding of the mechanisms of blood drop formation and flight require basic research into these phenomena.

Ames Laboratory cyclists completed the National Bike Challenge with a total of nearly 16,500 miles. Forty-six riders contributed to the total which placed the Lab fourth among the 62 Iowa teams registered for the event and 88th nationally out of 2,144 teams. Top riders for the Lab were Rebecca Shivvers, Gary Walter and Kyle Marchuk.
