Tunable Nanophotonic Infrared Filter Based on Thermochromic Vanadium Dioxide
Background Optical bandpass filters only allow incident light within one or more specified wavelength bands to be transmitted through or reflected from the device, while blocking others. The key parameters of these filters are the central or peak wavelength and the desired spectral range. Reflective filters using Fabry-Perot (FP) cavities reflect a...

Structured Polydimethylsiloxane (PDMS) Composite with Enhanced Thermal and Radiative Properties for Heat Dissipation
Background Heat sink operation relies on two major processes: conducting heat out of the device and dissipating the heat to a medium. Because the conduction process requires materials to have high thermal conductivity, metals like aluminum and copper are commonly used. However, the thermal emittance of metals is usually very low, resulting in suppressed...

Development of an artificial intelligence analysis method for magnetic particle imaging using a machine learning algorithm
iNTRODUCTION A magnetic particle imaging (MPI) device uses a changing magnetic field to cause superparamagnetic iron oxide (SPIO) nanoparticles to produce a signal upon exposure. The MPI device then detects these signals and produces a high contrast image. These images are useful in tracking SPIO throughout the body. This is useful in tracking transplanted...
