Avirup Roy, Robinjeet Singh, Joel Weber, William Doriese, Johnathon Gard, Mark Keller, John Mates, Kelsey Morgan, Galen O'Neil, Nathan Ortiz, Daniel Swetz, Daniel Schmidt, Joel Ullom, Evan Jahrman, Thomas Allison, Sasawat Jamnuch, John Vinson, Charles Titus, Cherno Jaye, Daniel Fischer

We present the electrothermal characterization of transition-edge sensor (TES) detectors suspended on Si membranes fabricated using a silicon-on-insulator wafer. The use of an all-silicon fabrication platform, in contrast to the more commonly used silicon

The electronic structure of oxyhemoglobin (oxyHb), the O2-bound form of the oxygen carrier, has been controversial since the discovery of its diamagnetism in 1936. This study uses partial fluorescence yield Fe L-edge X-ray absorption spectroscopy (XAS) in
