The exciting properties of micro-and nano-patterned surfaces found in natural species hide
a virtually endless potential of technological ideas, opening new opportunities for innovation …

Constructing and mimicking bioinspired structural color from bio-based materials has
aroused tremendous attention. Cellulose nanocrystals (CNC), a typical nanomaterial made …

Coatings for passive radiative cooling applications must be highly reflected in the solar
spectrum, and thus can hardly support any coloration without losing their functionality. In this …

Precise optical and thermal regulatory systems are found in nature, specifically in the
microstructures on organisms' surfaces. In fact, the interaction between light and matter …

Light is a powerful and sustainable resource, but it can be detrimental to the performance
and longevity of optical devices. Materials with near-zero light reflectance, ie superblack …

Disorder and photonics have long been seen as natural adversaries and designers of
optical systems have often driven systems to perfection by minimizing deviations from the …

Light influences most ecosystems on earth, from sun-dappled forests to bioluminescent
creatures in the ocean deep. Biologists have long studied nano-and micro-scale organismal …

Many animals convergently evolved photosynthetic symbioses. In bivalves, giant clams
(Cardiidae: Tridacninae) gape open to irradiate their symbionts, but heart cockles …

A renewable source of carbon black is introduced by the processing of lignin from agro‐
forestry residues. Lignin side streams are converted into spherical particles by direct …

Objective The aim of this study was to evaluate the optical properties of supra-nano
spherical fillers with different diameters and the color matching ability of resin composites …
