The extraordinary properties of biological materials often result from their sophisticated
hierarchical structures. Through multilevel and cross-scale structural designs, biological …

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 …

In this study, a novel poly (vinyl alcohol)(PVA)/poly (ethylene glycol)(PEG) scaffold was
carefully designed via thermal processing and subsequent supercritical fluid (SCF) foaming …

Energy-saving cooling materials with strong operability are desirable for sustainable thermal
management. Inspired by the cooperative thermo-optical effect in the fur of a polar bear, we …

A fundamental question regarding light scattering is how whiteness, generated from multiple
scattering, can be obtained from thin layers of materials. This challenge arises from the …

Natural creatures have evolved elaborate photonic nanostructures on multiple scales and
dimensions in a hierarchical, organized way to realize controllable absorption, reflection, or …

The wings of the black butterfly, Pachliopta aristolochiae, are covered by micro-and
nanostructured scales that harvest sunlight over a wide spectral and angular range …

The understanding of the interaction between light and complex, random structures is the
key for designing and tailoring the optical appearance and performance of many materials …

Biopolymers offer vast potential for renewable and sustainable devices. While nature
mastered the use of biopolymers to create highly complex 3D structures and optimized their …

A common strategy to optimize whiteness in living organisms consists in using 3D random
networks with dense and polydisperse scattering elements constituted by relatively low …
