Environmental Control of Ferroelectricity in Hafnia Films

Advanced Materials, EarlyView.
A reversible transition from nonferroelectric to ferroelectric behavior is achieved in hafnia films by modulating the surrounding atmosphere. The domain relaxation dynamics exhibit high sensitivity to environmental factors, including gas composition (ambient, N2, CO2, O2) and relative humidity, highlighting the crucial role of the measurement ...

Néel Tensor Torque in Polycrystalline Antiferromagnets

Advanced Materials, EarlyView.
This work introduces a Néel tensor torque based on a rank‐two symmetric tensor capturing spin correlations in a polycrystalline antiferromagnet. It shows the Néel tensor can be shaped and reshaped through the spin‐orbit torque (SOT) technique, enabling field‐free SOT switching with a specific polarity of the adjacent ferromagnet. This discovery opens a

Mixed Ionic and Electronic Charge Transport in Conductive Protein Fibers Revealed with DC Electrical Measurements

Advanced Materials, EarlyView.
M13 bacteriophage films deposited on micro interdigitated electrodes behave as a Randles simplified equivalent circuit under direct current. We derive contact and film resistance as well as capacitance of films of M13 phages, aromatic curli fibers or pilA‐containing nanowires.

Genetic Surfaceome E. coli Reprogramming Enables Selective Water Oxidation

Advanced Materials, EarlyView.
A novel enzymatic material based on bilirubin oxidase (BOD) surface‐expressed on E. coli for effective electrocatalysis is reported. With this material, highly efficient and selective water oxidation is achieved, a critical half reaction for synthetic photosynthesis. Abstract Programming catalytic behavior at the microbial genome level is a frontier in

Emergent Berry Curvature in Inversion‐Symmetric Photonic Crystals for Ultraconfined Topological States

Advanced Materials, EarlyView.
In this work, nonzero Berry curvature in photonic crystals is induced by breaking unit cell inversion symmetry through spatial shifts rather than geometrical modifications. This enables the design of ultraconfined topological states with subwavelength in‐plane field confinement and out‐of‐plane field isolation.

Machine Learning‐Enhanced Modular Ionic Skin for Broad‐Spectrum Multimodal Discriminability in Bidirectional Human–Robot Interaction

Advanced Materials, EarlyView.
A machine learning‐enhanced modular ionic skin with broad‐spectrum multimodal sensing is realized through a synergistic material–algorithm optimization strategy. This strategy involves hard‐segment‐modulated 1D/2D/3D‐ionic conductors and a data‐driven decoupling model trained on a curated multi‐stimuli dataset.
