A Crack‐Based One‐Dimensional Microspheres Array Enables Thermal–Mechanical Decoupled Dual‐Functional Sensing

Advanced Science, EarlyView.
Inspired by Nostoc, a crack‐based one‐dimensional microspheres array (COMA) sensor is developed, which stabilizes crack geometry under isotropic expansion, enabling a predictable, monotonic thermal response from which true strain can be accurately extracted. The COMA sensor exhibits high sensitivity at ultralow deformation (gauge factor up to 89) and a

Orbital and Electrical Dual Function of Polymer Intercalant for Promoting NH4+ Storage in Vanadium Oxide Anode

Advanced Energy Materials, Volume 15, Issue 11, March 18, 2025.
The impact of polyaniline insertion on the atomic orbitals and electronic structure of vanadium oxide anode is systematically investigated for the first time. The electrode exhibits an outstanding capacity and unprecedent long‐term cycling life, owing to the electron transition to the V 3dxy state and the enhanced diffusion kinetics.

Multiplicative Revan-Sombor Indices of Some Benzenoid Systems

International Journal of Mathematics And Computer Research, 2022
In this paper, we introduce the multiplicative modified Revan Sombor index of a graph. Also we compute the multiplicative Revan Sombor index, multiplicative modified Revan Sombor index of triangular benzenoids, benzenoid rhombus, benzenoid hourglass and benzenoid systems.

Electronic structure of solid coronene: differences and commonalities to picene

, 2011
We have obtained the first-principles electronic structure of solid coronene, which has been recently discovered to exhibit superconductivity with potassium doping. Since coronene, along with picene, the first aromatic superconductor, now provide a class

5,12‐TIPS‐Substitution of Tetracene: Effects on Redox Potentials and Cyclic Voltammetric Behavior in CH2Cl2 and THF1

Chemistry – A European Journal, EarlyView.
Tetracene and bis(tri(isopropyl)silylethynyl)tetracene (TIPS‐tetracene) exhibit characteristic similarities and differences in their electrochemical redox behavior depending on the base solvent of the electrolyte. Analysis of cyclic voltammograms allows the quantification of substituent and solvent effects and the calculation of an “electrochemical gap.

X-ray Structural Characterization of Charge Delocalization onto the Three Equivalent Benzenoid Rings in Hexamethoxytriptycene Cation Radical [PDF]

, 2009
Definitive X-ray crystallographic evidence is obtained for a single hole (or a polaron) to be uniformly distributed on the three equivalent 1,2-dimethoxybenzenoid (or veratrole) rings in the hexamethoxytriptycene cation radical.

Benzo[cd]azulenyl: A Structural Isomer of Phenalenyl—Synthesis and Properties of Its Tri‐tert‐butyl‐substituted Derivative and Formation of a Thermal‐ and Photoresponsive σ‐Dimer

Chemistry – A European Journal, EarlyView.
Benzo[cd]azulenyl, a nonalternant isomer of phenalenyl, is identified as a new member of the nonalternant hydrocarbon radical family. The tri‐tert‐butyl substituted derivative forms a stable σ‐dimer in the solid state. Upon exposure to external stimuli such as light and heat, the σ‐bond of the dimer dissociates, producing the monomeric radical.
