While 25°C is close to room temperature, cells can heat up quickly to much higher than this value (>40°C is readily possible) without some sort of active cooling (e.g., a fan or water-cooled plate) integrated into a solar simulator. The choice of these conditions can be understood,...
metabolism is directed toward the synthesis of hydrocarbons. Serving to enhance the capture of solar energy when illumination is low (a frequent occurrence in oceans), the HLR1-type antenna may represent an adaptation of these microalgae to life in the oceans, where there is a scarcity of nutri...
angle-dependent light harvesting opens up the possibility of generating optomechanical actuators that act both as back reflectors11,47and solar trackers. The reconfigurability of the photonic crystal layer and the ease of functionalization of silk matrix can provide new avenues for optical devices with...
Military and civilian emergency thermochromic applications require rapid visible-light stealth (VLS); however, concurrent smart solar transmission and rapid VLS is yet to be realized. Inspired by squid-skin, we propose a micropatterned thermochromic hydrogel (MTH) to realize the concurrent control of ...
