Micah Shepherd and Dr. Timothy Leishman, Physics and Astronomy After becoming familiar with measurement techniques and equipment, I measured the pressure of the sound field in 5 cm increments between the frequencies of 50 and 1600 Hz inside an impedance tube with a rigid termination. I then analyzed this data and found that the sound […]
Detecting the L10 Phase in Iron Platinum Thin Films by Electron Diffraction
Daniel Richardson and Dr. Richard Vanfleet, Physics and Astronomy Iron platinum is an exciting material being studied for its magnetic properties for possible use as the material in magnetic memory storage (e.g. hard drive). Why use iron platinum? In today’s technological world of ever decreasing dimensions, the hunt is on for mechanisms and materials that […]
Phylogenetic Analysis of Chroococcidiopsis
Brittany Renshaw and Dr. David Allred, Physics and Astronomy My research has focused on a genus of endolithic cyanobacteria called Chroococcidiopsis. These organisms are found in rocks from Antarctica to thermal springs and other arid or highly saline environments (Friedmann and Friedmann 1995). The organisms inhabit limestone and sandstone, appearing as a green band near […]
Quasi Phase Matching for Laser Second-Harmonic Generation in Glass
Nathan Powers and Dr. Justin Peatross, Physics and Astronomy Since the invention of lasers it has been possible to convert laser light into harmonics. This is a good way to achieve new shorter wavelengths of light. Unfortunately, all materials have a frequency-dependent refractive index that causes light of different frequencies to travel at different speeds. […]
Pearson Web Portal
Nathaniel Powell and Dr. Steve Turley, Physics Department So, when I was funded for this project I took seriously ill which dramatically reduced the amount of time I had to work on the project, but I was able to finish the rest of my classes recently and graduate. However, I have been funded for this […]
LASER BEAMS AND ZERO DEGREES: PROFESSORS PUT STUDENTS IN TOUCH WITH PHYSICS TECHNOLOGY
Sergei Voronov and John Madsen with Professor Justin Peatross Three professors in the College of Physical and Mathematical Sciences at Brigham Young University are including undergraduate students in joint physics projects using the latest laser technology. Twenty students—five graduates and fifteen undergraduates—are being mentored by professors Dallin Durfee, Justin Peatross and Scott Bergeson on several […]
Construction and Testing of Components for A New Atomic Frequency Standard
Justin Paul and Dr. Dallin Durfee, Physics During the course of the last year I have been working on several components that will be used in a next-generation atomic frequency standard, or atomic clock. Some of the projects that I have been working on include building a temperature controller for a laser diode head, aligning […]
Improved Extra Vehicular Activity by use of a Pressurized Martian Atmosphere
Simeon A Ning and Dr. David D. Allred, Physics and Astronomy In preparing for a manned mission to Mars, one problem that needs to be addressed is how to do servicing, building and maintenance work on Mars. This problem is related to space suit design. Past NASA explorations have used full pressure suits (FPS). These […]
Diode Laser with Hertz-Level Stability For Atom Interferometry
Brian Neyenhuis and Dr. Dallin Durfee, Physics and Astronomy Over the course of this grant we have completed the preliminary research for the first stabilization stage of our 657 nm diode laser. We have finished research on the theory behind our new extended cavity diode laser grating stabilization scheme, and were able to lock the […]
DNA/RNA Conductivity
Kaylee Sill (McElroy) and Dr. Robert Davis, Physics and Astronomy Determining properties of DNA and RNA, such as conductivity of the strands, could be essential in the development of bioelectronics. Both DNA and RNA have pi bonds, which form when an electron is ‘shared’ between multiple atoms. The electrons forming pi bonds may be able […]
