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).

Combinatorial Survey of Structural Phase Distribution and Magnetism in Fe‐Ge‐Te Composition‐Spread Thin Film Libraries

open access: yesAdvanced Electronic Materials, EarlyView.
ABSTRACT Magnetic 2‐dimensional (2D) van der Waals (vdW) materials have garnered tremendous attention. The vdW ferromagnet Fe5Ge1Te2 has a Curie temperature Tc of ≈ 270 K, which is tailorable by tuning the stoichiometry and the Fe deficiency to reach room temperature.

Broadband Near‐Field Computational Microwave Imaging Enabled by Nonperiodic Dispersive Unit‐Cell Loading in a Passive Metasurface

open access: yesAdvanced Electronic Materials, EarlyView.
A compact passive engineered surface converts changes in microwave frequency into many distinct illumination patterns, allowing nearby objects to be imaged without mechanical scanning, active tuning, or a large antenna array. Operating from 18 to 28 GHz, the single‐port system uses measured field patterns to reconstruct metallic targets and distinguish

Exploring Euclidean and Non-Euclidean Geometry

open access: yes, 2018
The Elements, compiled by Euclid, covers Greek plane and solid geometry and number theory using the axiomatic method. His work provided a foundation for many notable mathematicians of the time to delve deeper into the axiomatic approach in geometry.

Physical Unclonable Functions From Microwave Metasurface Fingerprints

open access: yesAdvanced Electronic Materials, EarlyView.
Nominally identical metasurfaces fabricated through standard PCB processes inevitably contain microscopic fabrication imperfections. This work demonstrates that these unavoidable electromagnetic deviations can serve as unique physical unclonable fingerprints for wireless authentication.
