Nano‐Scale Characterization of Impurities Segregation in Solid Oxide Electrolysis Cells

Advanced Functional Materials, EarlyView.
Cathodic polarization induces impurity segregation in Ni, forming an amorphous Na─Al─Si─O amorphous phase at grain boundaries. Under ultralow oxygen partial pressure, multiple elements dissolve, migrate, and reoxidize within the metal. A patterned model system provides direct nanoscale evidence, clarifying the mechanism of polarization‐driven impurity ...

Submicron Metasurface Reconfigured Multiband Smart Windows

Advanced Functional Materials, EarlyView.
This work presents a submicron metasurface reconfigured multiband thermochromic smart window. By integrating subwavelength nanostructures into a Fabry−Perot resonator configuration, it mitigates conventional trade‐offs to simultaneously deliver high luminous transmittance and robust solar heating and radiative cooling modulation capabilities ...

Shape Memory Microneedle to Prevent Risks of Reproductive Hormone Therapy by Switching Sustained to Burst Release Under a Single Transdermal Insertion

Advanced Functional Materials, EarlyView.
A shape‐memory microneedle system enables reproductive hormone therapy through a single transdermal insertion. The X‐shaped device sustains follicle‐stimulating hormone release for three days, and mild heating restores the O shape to trigger burst human chorionic gonadotropin release.

Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward

DESIGN AND REALIZATION OF DUAL BAND MICROSTRIP SIW ANTENNA

, 2019
Herein, realization of a high performance dual band microstrip antenna via the use of Substrate Integrated Waveguide technology (SIW) has been studied. Firstly, a 3D Electromagnetic based SIW antenna design has been modeled in CST Microwave Studio. The proposed dual band antenna is aimed to operate at 10 & 24 GHz frequency.

Sustainable Electrochemical Synthesis of High‐Quality MXenes: Mechanistic Insights, Applications, Challenges, and Technological Prospects

Advanced Functional Materials, EarlyView.
Electrochemical etching provides an eco‐friendly alternative to hazardous HF methods for MXene production. This approach facilitates the selective isolation of the A‐layer from MAX phases with tunable surface terminations. Controlling voltage, electrolytes, temperature, and duration enables the optimal structural integrity. Nevertheless, existing scale
