Phase Diagram and Electrostatic Levitation Undercooling Studies of Polytetrahedral Phases in Ti−Fe−Si−O and Ti−Zr−Ni Alloys
New information on the phase diagrams of Ti-Fe-Si-O and Ti-Zr-Ni alloys near the quasicrystal and rational approximant compositions is presented. α(TiFeSiO), the 1/1 rational approximant, is shown to form in a...

Anisotropic Aerogels for Studying Superfluid 3He
It may be possible to stabilize new superfluid phases of 3He with anisotropic silica aerogels. We discuss two methods that introduce anisotropy in the aerogel on length scales relevant to superfluid 3He. First, ...

Analysis of Strong-Coupling Parameters for Superfluid 3He
Superfluid 3He experiments show strong deviation from the weak-coupling limit of the Ginzburg-Landau theory, and this discrepancy grows with increasing pressure. Strong-coupling contributions to the quasiparticl...

Imaginary Squashing Mode Spectroscopy of Helium Three B
We have made precision measurements of the frequency of a collective mode of the superfluid 3He–B order parameter, the J=2− imaginary squashing mode. Measurements were performed at multiple pressures using inter...

Liquid to Semisolid Rheological Transitions of Normal and High-oleic Peanut Oils upon Cooling to Refrigeration Temperatures
Rheological transitions of peanut oils cooled from 20 to 3 °C at 0.5 °C/min were monitored via small strain oscillatory measurements at 0.1 Hz and 1 Pa. Oils were from nine different cultivars of peanut, and t...
