We report a study of the superconducting rhenium-based borides Mo7Re13B and W7Re13B by means of the 11B nuclear magnetic resonance (NMR) spectroscopy. Superconducting behavior with transition temperatures of 8.3 K and 7 K for Mo7Re13B and W7Re13B respectively have been reported. In the present work, NMR results indicate that the B Fermi level density of states is not predominated by p bands and the...
Time- and angle-resolved photoemission spectroscopy directly enables observation of electron dynamics in condensed matter. Using EUV high harmonic probe extends the observation window in energy and momentum. Tunable mid-infrared pumping allows control of excitation mechanisms.
Ultrasound-induced blood stasis has been observed for more than thirty years. Most of the literature has been focused on the health risks associated with this phenomenon and methods employed to prevent stasis from occurring during ultrasound imaging. To date, experimental observations have been either in vitro or invasive. The current work demonstrates ultrasound-induced blood stasis in murine tumor...
Near infrared (NIR) spectroscopy has been demonstrated as a new means to quantify oxygenation of tissue vasculature, in particular changes in hemoglobin concentrations and oxygen saturation. A novel application such oximetry to monitoring of tumor vascular oxygenation during respiratory interventions will be presented. Our recent results obtained with a one-channel NIR spectrometer observing rat breast...
We measured the extinction coefficient and refractive index (0.2-2.0 THz) of methyltrimethoxysilane (MTMOS) sol-gel, a bio-encapsulating polymer. Its low extinction coefficient makes it a promising matrix material for THz bio-sensing and biological spectroscopy.
