Adaptive Active Illumination Via Translationally and Axially Tunable Cascaded Metasurfaces

open access: yesAdvanced Science, EarlyView.
Active three‐dimensional sensing faces a fundamental trade‐off between seeing farther and covering more of the scene. Translationally and axially tunable cascaded metasurfaces overcome this limitation by continuously adapting beam direction and illumination coverage.

Automated Conformational Clustering Reveals Desolvation Mechanisms in a Wide‐Temperature‐Range Sodium‐Ion Electrolytes

open access: yesAdvanced Science, EarlyView.
Temperature‐driven solvation conformational shift reduces the desolvation barrier and enhances sodium‐ion mobility. ABSTRACT The desolvation kinetics of Na+ at the electrode‐electrolyte interface critically limit the wide‐temperature performance of sodium‐ion batteries (SIBs).

Solute‐Induced Modulation of Hydrogen Bonding, Ion Hydration, and Protonation in Hydrogels for Enhanced Microwave Absorption

open access: yesAdvanced Science, EarlyView.
Systematic solute screening reveals how noncovalent interactions regulate dielectric loss in P(AA‐co‐AM) hydrogels. By tuning proton conduction, ion hydration, and hydrogen‐bond interactions, the dielectric response can be precisely controlled, enabling tailored hydrogels with broadband microwave absorption and providing a general strategy for ...

Updatable Closed‐Form Evaluation of Arbitrarily Complex Multiport Network Connections

open access: yesAdvanced Electronic Materials, EarlyView.
The inverse design of electrically large wave devices often uses reduced‐order multiport models with discrete optimization, requiring many evaluations of complex interconnections between subsystems that differ only in a few blocks. This paper introduces a closed‐form framework enabling efficient Woodbury low‐rank updates of related, previous ...

Silicon Nitride Resistive Memories

open access: yesAdvanced Electronic Materials, EarlyView.
Amorphous SiNx is an attractive resistance switching material for ReRAM applications due to its physicochemical properties, such as humidity resistance, low oxygen diffusivity, and is used as a metal diffusion blocker. By modifying the ratio between N and Si atoms, the microstructure of the SiNx is affected, rendering it possible to change the ...
