Early detection of thermal contrast in pulsed stimulated infrared thermography

Proceedings of the 1994 International Conference on Quantitative InfraRed Thermography, 1994
Pulsed stimulated infrared thermography is a .powerful technique for the detection of thermally resistive defects in materials. Time-resolved analysis of the surface temperature field can then be used for the identification of· the defect characteristics (mainly its depth, its lateral size and its thermal resistance).

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

EcoEnergy, 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.

Bio‐Inspired Sclerotization of Lignin: A Robust Adhesive for Photothermal Wood‐Based Panels

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A high‐performance lignin adhesive is engineered via an insect‐inspired sclerotization strategy involving oxidation and hyperbranched polymer grafting, overcoming lignin's adhesion failure, and yielding a wet shear strength of 1.02–1.21 MPa. The adhesive endows wood‐based panels with photothermal functionality; building energy simulations indicate HVAC‐

Antiferroelectric Phase Transitions Under Electric Fields: A Review of Physics and Applications

Interdisciplinary Materials, EarlyView.
Field‐induced phase transitions in antiferroelectric materials, driven by electric field, temperature, or stress, enable diverse applications including energy storage, electrocaloric cooling, and negative capacitance. These transitions are regulated through compositional design, strain engineering, heterostructure, and size effect, providing a unified ...
