Novel Silicon Radiation Detector Enabled By Tunnel Oxide Passivating Contact	The technology passivates the bottom surface well and suppresses electron recombination near the bottom contact, resulting in low leakage current. Passivating the silicon surface and decreasing hole recombination near the front contact leads to low recombination current density at the surface and low effective contact resistivity. An extremely low J0 for the tunnel oxide passivating contact on both sides yields a higher energy resolution and lower noise level.	9227
Parametric Resonance Approach for Efficient, Versatile Acoustic Power Transfer for Implantable/Wearable Devices, Sensing, and Communications	New class of transducers utilizes parametric resonance to convert acoustic energy from an ultrasonic source to a sustained electrical signal.
