An original and low cost method for the fabrication of patterned surfaces bioinspired from butterfly wings and lotus leaves is presented. Silica-based sol-gel films are thermally imprinted from elastomeric molds to produce stable structures with superhydrophobicity values as high as 160 degrees water contact angle. The biomimetic surfaces are demonstrated to be tuned from superhydrophobic to superhydrophilic by annealing between 200 degrees C and 500 degrees C.

Given extremely high porosity, aerogels have demonstrated remarkable advantages in serving as thermal insulation and wave-transparent materials. Unfortunately, their practical applications are greatly confined by their inherent fragility. The recent emergence of polymer aerogels presents an ideal platform for the development of flexible aerogel films.

Self-powered broadband photodetectors (SPBPDs) hold great potential for next-generation optoelectronic applications, but their performance is often limited by interface defects that impair charge transport and increase recombination losses. In this work, we report the enhancement of the photodetection efficiency of SPBPDs by partially substituting copper (Cu) with silver (Ag) in kesterite CuZnSnS (ACZTS) thin films. Varying Ag concentrations (0%, 2%, 4%, 6%) are incorporated into the CZTS layer, forming a TiO/ACZTS heterojunction in superstrate configuration fabricated via a low-cost sol-gel spin-coating technique with low-temperature open air annealing avoiding conventional postdeposition sulfurization or selenization.

The scales of the gold-dust weevil are green because of three-dimensional diamond-type chitin-air photonic crystals with an average periodicity of about 430 nm and a chitin fill fraction of about 0.44. A single scale usually contains one to three crystallites with different lattice orientations.
