Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity
This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...

Shear‐Induced Nematic Alignment in Polysulfone Melts
Shear‐induced alignment is investigated by means of rheology and birefringence on an amorphous linear polysulfone melt. The absence of crystallization makes PSU particularly enabling to investigate temperature effects on the shear‐alignment of linear polymers, unveiling the role of chain relaxation times and possible enthalpic contributions.

Superlubricious Surfaces Through Surface Attached Hydrogels Obtained by C,H‐insertion Crosslinking
Taking synovial joints as a source of inspiration, the friction properties of surfaces covered with 1d‐swelling polyelectrolyte hydrogels in combination with a shear‐thinning aqueous lubricant are studied. Such systems obtained by C,H insertion crosslinking show superlubricious behavior, even surpassing the friction values reported for the natural ...

A Close Look at the Local Structure of Functional Polymers: The Example of Poly(Vinylidene Fluoride)
To accurately develop structure‐property relationships in functional macromolecules, it is increasingly important to consider the local chain arrangement in addition to long‐range order. It is demonstrated in the case of poly(vinylidene fluoride) that solid‐state nuclear magnetic resonance (NMR) spectroscopy can provide detailed insights into the local

Multi‐Scaled Cellulosic Nanonetworks from Tunicates
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–
