Classification of iron oxide aerosols by a single particle soot photometer using supervised machine learning [PDF]

Atmospheric Measurement Techniques, 2019
Single particle soot photometers (SP2) use laser-induced incandescence to detect aerosols on a single particle basis. SP2s that have been modified to provide greater spectral contrast between their narrow and broad-band incandescent detectors have ...

Directional enhancement of photoluminescence from phosphor plates with TiO2 nanoantenna stickers

Nanophotonics, Volume 14, Issue 25, Page 4627-4636, December 2025.
Abstract Directional illumination is critical for next‐generation solid‐state lighting. In this study, we demonstrate that flexible nanoantenna stickers enhance photoluminescence (PL) directionality. By integrating YAG:Ce phosphor plates and distributed Bragg reflectors (DBRs), these stickers achieve controlled radiation distribution, advancing the ...

Enhanced Mobility and Stability in Solution‐Processed Mo–Pr Co‐Doped In2O3 TFTs Guided by Machine Learning Optimization

Electron, Volume 3, Issue 4, November 2025.
Schematic diagram of synergistic interaction between Mo and Pr in InPrMoO films. ABSTRACT In2O3‐based TFTs have garnered widespread attention due to their higher mobilities than amorphous silicon. Previous studies have indicated that rare earth doping can enhance the NBIS stability of TFTs, but this often results in a decrease in mobility.
