Decoding THz‐Driven Dynamic Fingerprints of Ferroelectric Nanotwin Networks
ABSTRACT Ultrafast polarization dynamics in ferroelectrics are of considerable interest for high‐speed tunable dielectrics and electro‐optics. Extended domain wall networks formed in ferroelectric twin nanodomains can support collective dynamics in the terahertz regime but require techniques that track polarization and strain evolution driven by ...

A Family of Sodium Solid‐State Electrolytes Based on the NaGaxAl1‐xCl4 Solid Solution
ABSTRACT Sodium‐based metal chloride solid electrolytes are promising for sodium solid‐state batteries due to their excellent oxidation stability, which, as shown for Li halides, can coexist with high ionic conductivity. To explore cationic substitution effects, we synthesized NaGaxAl1‐xCl4 (0 ≤ x ≤ 1) via ball milling and investigated structural and ...

Although electrochemical scanning tunneling microscopy provides atomic‐scale access to electrified interfaces, quantitative in situ and operando investigations suffer from drift‐induced distortions. This work introduces the Lattice Fourier Analyzer (LFA), which employs substrate‐anchored affine drift correction in reciprocal space to recover precise ...

Bioresorbable electrochemical sensors face instability in biofluids. Although alloys can mitigate rapid in vivo dissolution, Mo–W remains underexplored for sensing. This work engineers Mo–W films with a nanocrystalline oxide coating, improving stability and enabling reliable oxygen and pH sensing for up to 10 days, highlighting their potential for ...

Low‐temperature passivation of SiC reveals that optical surface quality and chemical stability are not directly correlated. Ar plasma‐treated and SiNx‐passivated surfaces yield the lowest photoluminescence background, whereas CF4 plasma and ALD‐grown dielectrics introduce higher emission.

Layered Nanoporous Platforms for SERS Sensing
Here, we present a detailed investigation of the SERS performance of layered nanoporous metals. The controlled deposition of well‐defined, stacked porous layers enabled a systematic analysis of the effects of multimetallic systems in SERS experiments. Numerical models are also used to support the experimental findings.

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications
A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.
