Broadband Parametric Amplification in AlGaAs‐on‐Insulator Nanowaveguides
Harnessing the exceptional nonlinearity of AlGaAs‐on‐insulator nanowaveguides, four‐wave‐mixing parametric amplification achieves a record net on‐chip gain of 56 dB and a gain bandwidth exceeding 415 nm at telecom wavelengths. These results establish AlGaAsOI as a powerful platform for compact, high‐performance integrated nonlinear optical ...

“White and Clear” (WaC): A tunable hydrophilic tissue clearing strategy for multi‐species 3D imaging
Optical tissue clearing methods help scientists make tissues transparent to image structures deep inside organs in 3D, but many existing techniques are limited in performance and difficulty. In this study, we developed an optimized clearing method called WaC (White and Clear), which improves upon existing techniques by combining efficient tissue ...

Cement phases are good materials for radiative cooling thanks to the selective emissivity in IR ATW. Cement powders have high reflectance of solar radiation which reduces the thermal losses. The onset of the absorption curves is defined by bound excitons. Sulfates have higher radiated powers and reflectance than calcium silicates.
