Applied Sciences, 2018 Carbon fiber bicycle frames are complex-shaped structures and are prone to delaminations and difficult to inspect. The use of finite element model updating is common in structural dynamics but not so common in active thermography inspection.

Investigation of delamination in carbon fiber reinforced plastic by means of pulse thermography, shearography and active thermography [PDF]
Proceedings of Meetings on Acoustics, 2019 Carbon fiber reinforced polymer is a material widely used nowadays in different application areas. All sectors, especially the aeronautics industry, demand components of high mechanical performance, but also with high durability and reliability, hence the need for advanced health assessing methods and to monitor the integrity of the components ...

Localized 3D acoustic streaming in microdroplets using high‐frequency micro‐beam IDTs
Droplet, EarlyView.Miniaturized 160 MHz acoustic microbeam transducers, with a size much smaller than droplets, enable precise localized actuation, generating complex three‐dimensional streaming and tunable particle aggregation. This concept provides high‐resolution, non‐contact fluid manipulation for biosensing, lab‐on‐chip diagnostics, and targeted drug screening ...

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‐

Thermographic Non-Destructive Evaluation for Natural Fiber-Reinforced Composite Laminates
Applied Sciences, 2018 Natural fibers, including mineral and plant fibers, are increasingly used for polymer composite materials due to their low environmental impact. In this paper, thermographic non-destructive inspection techniques were used to evaluate and characterize ...

Detection of Differentiated Tissue with Pulse Thermography
Proceedings of the 2014 International Conference on Quantitative InfraRed Thermography, 2014 We report on the study of the relationship between the length of the pulses and the depth of the boundary to be detected in thermally transmissive tissues within the therapeutic window, red to IR spectral range. We use a three-layer theory to predict the possibility of detection of an abnormal growth. 1.
