Achieving Chemical Recognition, Recycling, and Circularity With Radical Nanostructures
Advanced Functional Materials, EarlyView.Here, innovative 3D radical nanostructures based on 4,4′‐dicyano‐2,2′‐biphenylene‐fused tetrazolinyl radical, fabricated on interdigitated gold‐SiO2 hybrid surfaces are presented. They retain their magnetic properties, their morphology and size can can tune, selectively remove them from specific substrate regions using distilled water, and return the ...

A New Memory Effect in Bulk Crystals of 1T‐TaS2
Advanced Functional Materials, EarlyView.A new memory effect is discovered in 1T‐TaS₂, appearing as a temperature shift in the metal to insulator transition, coinciding with the recently reported ramp reversal memory. These findings imply that ramp reversal memory is an emergent phenomenon, likely to appear in many different systems that share a few basic properties, which are discussed in ...

Conformally Perforated Shellular Metamaterials with Tunable Thermomechanical and Acoustic Properties
Advanced Functional Materials, EarlyView.This study introduces Conformally Perforated Shellular Metamaterials (CPSMs), which overcome TPMS design limitations by mapping 2D cellular layouts onto 3D surfaces. CPSMs exhibit enhanced elastic stiffness, thermal conductivity, and acoustic performance compared to intact P‐type shellulars, demonstrating their potential as multifunctional ...

Defects in Inorganic Mechanoluminescent Phosphors: Insights and Impacts
Advanced Functional Materials, EarlyView.Mechanoluminescence is attracting more attention recently, and defect dominates mechanoluminescence performances. Investigating how defects work in the mechanoluminescence process is crucial for elucidating its complex luminescence mechanism. This review aims to emphasize the fundamental role of defects in mechanoluminescence, which offers an ...

Semigroup Generation Theorems of Anti-Triangular Operator Matrices and Their Application
Journal of MathematicsThis paper deals with the semigroup generation of anti-triangular operator matrices M with unbounded entries in Hilbert space. Based on the space decomposition, some necessary and sufficient conditions are given for M to generate contraction semigroups ...
