Beyond Brown: Lignin's Emerging Role in Structural Color

Advanced Optical Materials, EarlyView.
Lignin, long regarded as a brown industrial byproduct, is emerging as a sustainable platform for structural color. This Perspective highlights how lignin's refractive index, intrinsic absorption, and nanoscale assembly enable tunable photonic responses in colloidal and thin‐film architectures, and outlines design strategies to advance scalable, bio ...

On the Origins of Toughness in Corymbia calophylla (Marri Tree) Nuts

Advanced Science, EarlyView.
We uncover the natural toughening mechanisms of the marri nut, including fiber pullout, crack deflection, and a viscoelastic matrix, which enable exceptional energy absorption and ductility comparable to Teflon, with an elastic modulus similar to acrylic.

Lewis Pair‐Engineered CuMnOx as Cold‐Adapted Multinanozyme for Cooperative Hydrolytic and Oxidative Degradation of Raw Corn Stalk

Advanced Science, EarlyView.
A Lewis pair site design strategy was established to construct Cu‐doped Mn‐based amorphous nanozymes, where Mn and oxygen vacancies generate cooperative acid‐base pairs. The resulting multinanozyme integrates glycosidase‐, oxidase‐, and cold‐adapted enzyme‐mimicking activities, enabling cooperative depolymerization of cellulose and hemicellulose ...

Ultrastrong TEMPO‐Oxidized Densified Bamboo via Interface Decoupling and Hierarchical Toughening

Advanced Science, EarlyView.
This study develops TEMPO‐oxidized densified bamboo that achieves ultrahigh strength and toughness by decoupling rigid hydrogen bonds into reversible van der Waals interactions. TEMPO oxidation reorganizes the cellulose hydrogen‐bonding network, facilitating energy dissipation via reversible interactions, thereby establishing a general strategy to ...
