Brett Guisti High-temperature x-ray diffraction experiments have long been of interest for the characterization of materials with phase transitions and other structural variations above room temperature. Examples include cubic zirconia transitioning from cubic to tetragonal below 500°C, β-Alumina gradually moving from an ordered to a disordered state as temperature increases, and superionic conductors like Bi4V2O11.

A CCD Photometric Search for Variable Stars in the Open Cluster NGC 188
Andrew Davis and Dr. Eric Hintz, Physics and Astronomy The old open cluster NGC 188 is unique because of its large number of W UMa type contact binaries. This allows astronomers to use these stars to refine models of the origin and evolution of these systems. Also because of its age, NGC 188 may display […]
The Growth of Single-Walled Carbon Nanotubes on Atomic Force Microscope Tips
Michael Clemens and Dr. Robert Davis, Physics and Astronomy The Atomic Force Microscope (AFM) is a powerful instrument that has many applications in various fields of scientific research. It has the ability to image surfaces without requiring a high vacuum and has the ability to image samples that are in a fluid. It also is […]
Direct Measurement of Absorption Rates for Laser High-order Harmonics Generated in Helium and Neon
Eric Christensen and Dr. Justin Peatross, Physics and Astronomy Extreme ultraviolet (EUV) light can be generated through the interaction of a high-intensity laser beam with atoms. When an intense laser pulse hits an atom, its outer electron is pulled away from the atom. The electric field of the laser may then pull the electron back […]
DATA REDUCTION AND PUBLICATION OF BYU’S CCD IMAGES OF COMET HYAKUTAKE
Kimball Staples & Nephi Thompson & Dr. J. Ward Moody, Physics and Astronomy In March 1996, Dr. J. Ward Moody and Dr. Clark Christiansen obtained a series of approximately 120 CCD (solid state electronic) images of Comet Hyakutake. The images were taken at the National Optical Astronomy Observatory on Kitt Peak, near Tucson, Arizona. The […]
SAMPLE PREPARATION FOR TRACE ELEMENT ANALYSIS OF COMMERCIAL ARTISTS’ PAINTS USING PIXE
Silas Menlo Scott and Dr. Lawrence Rees, Physics and Astronomy Particle Induced X-Ray Emission (PIXE) has been used extensively in the study of items of artistic interest. One area of interest has been determining the chemical composition of various artists’ materials.1 Many companies offer a wide variety of artists’ paints. While the chemical makeup of […]
Unique Rotating Platform for Acoustical Research
Richard T. Watkins and Dr. Tim Leishman, Physics and Astronomy A few weeks into the development of this project, several factors became apparent that we did not anticipate when I wrote the original proposal. The table size needed to be larger than first envisioned to make possible the experiments and data collection that would be […]
Novel Preparation and Single Crystal Analysis of Layered Metal-doped Vanadates
Jeffrey Watkins and Dr. Branton J. Campbell, Physics and Astronomy Layered transition-metal-doped bismuth vanadates, commonly known as BIMEVOX oxides, have very attractive oxygen-ion conductivity properties at moderate temperatures and show promise in applications as electrode materials and membranes for oxygen separation. Of great interest is the relationship between the atomic structure of BIMEVOX materials and […]
Non-Commutative Simple Harmonic Oscillator
Mark Transtrum and Dr. Jean-Francois Van Huele, Physics and Astronomy Non-commutative quantum mechanics is an active field of research in which the operators corresponding to different spatial dimensions are assumed to not commute, as a consequence of quantization of spacetime. This field is important because it investigates the relationships between fundamental physical ideas such as […]
Development of Algorithms for the Manipulation of Non-commutative Structures in Quantum Theory
Mark Transtrum and Dr. Jean-Francois Van Huele, Physics and Astronomy Quantum mechanics is one of the fundamental theories of physics. Its formal mathematical description is marked by the appearance of non-commutative operators. The non-commutativity provides a rich mathematical language appropriate for describing quantum theory. The commutator of two operators is defined as the difference between […]
