All‐Cellulose‐Based Photonic Glitters
Uniform, disc‐shaped photonic CNC glitters with adjustable structural colors and diameters are fabricated on hydrophilic ethyl cellulose films using electrospray deposition. By employing patterned ethyl cellulose films with pre‐designed hydrophilic regions, photonic patterns can be created with these all‐cellulose‐based glitters, demonstrating their ...

Anomalous Suppression of Valley Splittings in Lead Salt Nanocrystals without Inversion Center
Atomistic sp3d5s* tight-binding theory of PbSe and PbS nanocrystals is developed. It is demonstrated, that the valley splittings of confined electrons and holes strongly and peculiarly depend on the geometry of a nanocrystal. When the nanocrystal lacks a

Flexible Leaf‐Like Fuel Cell From Plasmonic Janus Nanosheet
A flexible leaf‐like fuel cell is fabricated by conductive gold nanowire sponge‐supported plasmonic Janus nanosheet, which can generate a power of 8.93 mW cm⁻2 with less than 10% performance deterioration even being bent or twisted. Further assembly in a tree‐like layout demonstrates omnidirectional light harvesting capability and wind resistance ...
