Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

open access: yesEcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

Finite Element Analysis for Li Batteries at the Mesoscale

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Finite element analysis (FEA), through multi‐physics coupling, has been widely employed to calculate mesoscale structures in LIBs that exhibit inherent randomness and disorder (Figure a). It has been extensively applied to the investigation of critical phenomena such as Li dendrite evolution, Li+ concentration gradients, SEI film growth, particle ...

Numerical and Experimental Evaluation of a Simplified Lateral Spring Formulation for Rocking Structures

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been

A note on the implementation of the hyperelastic Kilian model in the Abaqus

open access: yesCoRR, 2019
The main goal of the article is to verify the implementation of the Kilian material model in the Abaqus/Standard. The key feature of the model is that it describes so called strain locking, which results directly from a structure of the stored energy function.

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

open access: yesFire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Wide‐range and high‐resolution Young's modulus sensing enabled by a complementary indentation‐protrusion architecture

open access: yesFlexMat, EarlyView.
A tactile sensor integrating indentation and protrusion sensing within a single platform enables accurate perception of object Young's modulus. This complementary architecture expands the detectable Young's modulus range to 25.8–2639.2 kPa and achieves an object recognition accuracy of 94.27%, outperforming indentation‐only (84.59%) and protrusion‐only

Plastic luminescence in mechanoluminescent composites

open access: yesInfoMat, EarlyView.
Through compression tests and numerical simulations, this study demonstrates that the luminescence of a mechanoluminescent (ML) composite is strongly associated with plastic strain, thereby providing new insight into deformation‐induced luminescence during the plastic stage.
