Advanced 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 ...

Geometric spin foams, Yang-Mills theory and background-independent models
, 2005 We review the dual transformation from pure lattice gauge theory to spin foam models with an emphasis on a geometric viewpoint. This allows us to give a simple dual formulation of SU(N) Yang-Mills theory, where spin foam surfaces are weighted with the ...

Advanced Materials, EarlyView.High‐entropy materials (HEMs), typically composed of five or more principal elements in near‐equimolar ratios, offer significant potential due to their unique properties. This review outlines the emergence and structural evolution of HEMs, followed by an in‐depth discussion of the elemental roles (active sites, promoters, or stabilizers) for water ...

Biocompatibility and Long‐Term Stability of DNA‐Based Organic Mixed Conductors for Bioelectronics
Advanced Materials Interfaces, EarlyView.The biocompatibility and long‐term stability of DNA‐based mixed ionic‐electronic conductors are investigated. In vitro cytotoxicity and cell viability are assessed using flow cytometry assay on primary mouse fibroblasts cultures. The biocomposites are integrated into organic electrochemical transistors (OECTs) to determine the stability of their ...
