Electrostatic Superlattices Beyond 1:1 Stoichiometry

Advanced Functional Materials, EarlyView.
Polymer‐mediated charge regulation drives two hierarchical routes to higher‐stoichiometry nanoparticle superlattices. Tuning the polymer's molecular weight promotes progressive interstitial filling, transforming ZnS into the fully occupied CaF2${\rm CaF}_2$ lattice. Exchanging polymer assignment between large and small nanoparticles instead breaks CsCl

Glass Formation and Desiccation Tolerance in Seeds [PDF]

Plant Physiology, 1991
The formation of intracellular glass may help protect embryos from damage due to desiccation. Soluble sugars similar to those found in desiccation tolerant embryos were studied with differential scanning calorimetry. Those sugars from desiccation tolerant embryos can form glasses at ambient temperatures, whereas those from embryos that do not tolerate ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite

Advanced Functional Materials, EarlyView.
The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Morphological and Ecological Traits Explain Variation in Desiccation Tolerance Among Bees

Ecology and Evolution
Rising temperatures associated with global warming are often accompanied by shifts in precipitation patterns, increasing the risk of desiccation for insects. However, our understanding of how functional traits shape desiccation tolerance remains limited,

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

Advanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

2D Co‐Assembly of Solid Acids Enables Stable Superprotonic Conduction Above 260°C

Advanced Functional Materials, EarlyView.
A two‐dimensional co‐assembly strategy integrates antimony phosphate and phosphotungstic acid nanosheets into free‐standing inorganic lamellar membranes with confined acid–acid interfaces. The resulting interfacial hydrogen‐bond network enables anhydrous proton conductivity exceeding 0.1 S cm−1 at 260°C and supports stable high‐temperature fuel‐cell ...

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials

Advanced Functional Materials, EarlyView.
Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...
