Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

Advanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Spin‐Dependent Photoluminescence in Carbon‐Based Quantum Dots

Advanced Materials, EarlyView.
Here we report, for the first time, room‐temperature magneto‐photoluminescence and optically detected electron spin‐resonance in carbon quantum dots (CQD). We perform measurements on a series of amino acid derived CQD at room temperature and demonstrate their sensing potential by detecting paramagnetic molecules in solution.

Photochromic Cholesteric Liquid Crystals via Arylazopyrazole Functionalization of Hydroxypropyl Cellulose

Advanced Materials, EarlyView.
We produce a new derivative of hydroxypropyl cellulose functionalized with arylazopyrazole side chains and demonstrate its photoswitchable behaviors in dilute and concentrated aqueous solutions, ultimately designing a series of photochromic cholesteric materials that can be photopatterned as write‐erase displays.

Self‐Powered Flexible Triboelectric‐Gated Ion‐Gel Transistor for Neuromorphic Tactile Sensing and Human Activity Recognition

Advanced Materials, EarlyView.
A fully flexible ion‐gel‐gated graphene‐channel transistor driven by a triboelectric nanogenerator enables self‐powered tactile sensing and synaptic learning. Mimicking spike‐rate‐dependent plasticity, the device exhibits frequency‐selective potentiation and depression, supporting rate‐coded neuromorphic computation even under flex.

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications

Advanced Materials, EarlyView.
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

Large‐Area 2D Metasurface‐Based Triboelectric E‐Skin Arrays: Contact & Proximity Tactile Mapping with Broadband Acoustic Readouts

Advanced Materials, EarlyView.
Metasurface‐engineered NC‐TENG arrays integrate tactile pressure mapping, non‐contact gesture sensing, and acoustic signal readouts in one ultrathin module, and outperforms pristine PDMS in terms of electrical output and real‐time spatial mapping for next‐gen wearables.

Surface‐Capped Protein Nanoparticles for Nonviral Gene Delivery

Advanced Materials, EarlyView.
ABSTRACT Developing simple, safe, and efficient nonviral delivery systems remains a significant challenge in bioengineering. Nanoparticles offer promising gene delivery capabilities with reduced toxicity; however, long‐standing challenges related to effective plasmid encapsulation and delivery exist.
