Triboelectric Nanogenerators Enable Multifunctional Ice Accretion, Melting, and Interfacial Fracture Detection

open access: yesAdvanced Materials, EarlyView.
Water impacting, freezing, melting, and being mechanically removed from the designed dielectric surfaces generates a triboeletric signal that can be used to detect various icing and de‐icing scenarios. The charge transferred directly scales with the interfacial fracture mechanism, further validating triboelectricity as an excellent ice‐detection ...

High‐Performance Phototransistor Based on a 2D Polybenzimidazole Polymer

open access: yesAdvanced Materials, EarlyView.
A crystalline 2D polybenzimidazole polymer (2DPBI), incorporating a porphyrin‐based π‐system linked via 1,3‐diazole units, is synthesized on the water surface over large areas. The 2DPBI thin‐film exhibits high charge carrier mobility (≈240 cm2 V−1 s−1, measured by terahertz spectroscopy), strong photoresponse, and band‐like transport, enabling ...

Localized Spin Textures Stabilized by Geometry‐Induced Strain in 2D Magnet Fe3GeTe2

open access: yesAdvanced Materials, EarlyView.
Strain engineering in 2D van der Waals ferromagnet Fe₃GeTe₂ is studied using scanning transmission X‐ray microscopy. Spatially varying strain from micropillar arrays induced local 10 K Curie temperature increases, stabilizing magnetic domains including skyrmions and skyrmion bags near pillar corners.

A characterization of adjunction in a many-valued modal system

open access: yesCQD Revista Eletrônica Paulista de Matemática
Galois connections are pairs of functions, defined over ordered sets, that preserve some particular aspects. They are studied in the context of algebraic structures.

MINIMAL MODAL LOGICS, CONSTRUCTIVE MODAL LOGICS AND THEIR RELATIONS

open access: yesThe Review of Symbolic Logic
Abstract We present a family of minimal modal logics (namely, modal logics based on minimal propositional logic) corresponding each to a different classical modal logic. The minimal modal logics are defined based on their classical counterparts in two distinct ways: (1) via embedding into fusions of classical modal logics through a natural extension

Long‐Range Spin Transport in Chiral Gold

open access: yesAdvanced Materials, EarlyView.
It is demonstrated that in chiral gold film, spin information can be transferred to distances of several microns at room temperature. The conduction of spins is accompanied by the Hall effect that exists without applying an external magnetic field. The spin diffusion length is consistent with the frequency‐dependent Hall effect which indicates spin ...
