Semiconducting Covalent Organic Frameworks Based on Spin‐Delocalized Trioxotriangulene Neutral Radicals

Angewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Imine‐linked 2D covalent organic frameworks incorporating delocalized trioxotriangulene (TOT) neutral radicals were synthesized through complementary routes. Direct incorporation of an amine‐functionalized TOT radical yields a highly crystalline, porous framework (TOT‐COF‐H) with intrinsic semiconducting behavior (σRT = 1.2 × 10−4 S cm−1) and a narrow ...

The Virtual Pivot: Adaptive Investor Relations in the Face of Disruption Le virage virtuel : le caractère adaptatif des relations avec les investisseurs face aux perturbations

Contemporary Accounting Research, EarlyView.
ABSTRACT The capacity of firms to communicate effectively with investors during periods of disruption is a critical but understudied dimension of corporate adaptability. The COVID‐19 pandemic offers a rare empirical setting to observe such adaptability: It eliminated in‐person investor events almost overnight, forcing firms to either withdraw from ...

Amphoteric Cu‐Doping Leading to High Thermoelectric Performance in p‐Type Bismuth Antimony Telluride

Advanced Functional Materials, Volume 36, Issue 88, 2 November 2026.
This study shows that Cu plays two opposite roles in p‐type Bi0.5Sb1.5Te3 depending on the processing route. Under thermodynamic‐equilibrium bulk‐synthesis, Cu mainly occupies cation sites, increases hole concentration, preserves mobility, and slightly reduces lattice heat transport. The best‐performing composition among the investigated series reaches

Elementary Steps of Energy Conversion in Strongly Correlated Systems: Beyond Single Quasiparticles and Rigid Bands

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This article reviews the fundamental consequences of strong correlations on excitations and elementary steps of energy conversion leading to new opportunities to control energy conversion. Examples include friction at surfaces, thermal transport, and photovoltaic energy conversion.

Pore‐Defect Synergistic Decoupling of Electrical and Thermal Transport in Entropy‐Engineered Thermoelectric Ceramics

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Pore engineering reduces the thermal conductivity of thermoelectric materials, yet typically degrades electrical conductivity by enhancing carrier scattering—a long‐standing trade‐off. Here, we overcome this trade‐off in SrTiO3‐based entropy‐engineered ceramics via a one‐step synergistic strategy: using poly(methyl methacrylate) (PMMA) as a ...
