Multistate Ferroelectricity Enabled by Electrically Controlled Phase Transition of Two-Dimensional Ices.

Multistate ferroelectric polarization holds promise for realizing high-density nonvolatile memory devices, but so far is restricted to a few traditional ferroelectrics. Here, we show that nanoconfined two-dimensional (2D) ferroelectric ice can achieve phase-dependent multistate polarization through extensive classical and ab initio molecular dynamics simulations. An in-plane electric field is found to induce the reversible transition between a low-polarization AA-stacked hexagonal ice phase and an unprecedented high-polarization AB-stacked ice phase, resulting in a four-state ferroelectric switching pathway.

Bioinspired Multifunctional Eutectogels for Skin-Like Flexible Strain Sensors with Potential Application in Deep-Learning Handwriting Recognition.

Polymerizable deep eutectic solvents (PDES) have recently emerged as a class of solvent-free ionically conductive elastomers and are considered among the most feasible candidates for next-generation ionotronic devices. However, the fundamental challenge persists in synergistically combining high mechanical strength, robust adhesion, reliable self-healing capacity, and effective antimicrobial performance within a unified material system capable of fulfilling the rigorous operational demands of next-generation ionotronic devices across multifunctional applications. Inspired by the hierarchical structure of spider silk, HCAG eutectogels composed of acrylic acid (AA), 2-hydroxyethyl acrylate (HEA), and choline chloride (ChCl) were successfully synthesized via a one-step photopolymerization method.

Arbuscular mycorrhizal fungi enhance nitrate ammonification in hyphosphere soil.

Microbial nitrate ammonification is a crucial process to retain nitrogen (N) in soils, thereby reducing N loss. Nitrate ammonification has been studied in enrichment and axenic bacterial cultures but so far has been merely ignored in environmental studies. In particular, the capability of arbuscular mycorrhizal fungi (AMF) to regulate nitrate ammonification has not yet been explored.

A BtpB-Deleted Brucella Vaccine Strain Provides Dual Advantages: Enhanced Protection and Diagnostic Differentiation Capability in Mice.

The Brucella abortus A19 attenuated live vaccine poses potential infection risks during practical applications and interferes with serological diagnostics, thereby affecting quarantine measures and the establishment of disease-free zones. Consequently, this study aimed to reduce its potential virulence, enhance its protective efficacy and differentiate it from wild-type strains by knocking out the immunosuppressive virulence gene btpB in the A19 strain. Using homologous recombination, we successfully obtained the A19ΔBtpB deletion strain.
