The second near-infrared window (NIR-II; 1000–1700 nm) has emerged as a transformative modality for biological imaging, offering reduced photon scattering, minimal tissue autofluorescence and enhanced ...

(a) Energy transfer process of ideal thermochromic windows in winter daytime (left) and summer daytime (right). (b) The ideal spectrum of thermochromic windows against the normalized AM1.5 global ...

Passive daytime radiative cooling has emerged as a promising strategy for reducing building energy consumption without additional electricity input. By reflecting solar radiation while simultaneously ...

A thermochromic film embedded with size-optimized microcapsules autonomously switches between passive heating and cooling modes while maintaining high infrared emission for all-season thermal ...
