PDA‐Engineered 3D‐Printed Polymer–ZrO2 Hybrid Scaffolds Enabling Enhanced Radiopacity, Photothermal Therapy, and Cell Migration Modulation

Small, EarlyView.
A multifunctional 3D‐printed polymer–ZrO2 scaffold is developed to provide intrinsic radiopacity, photothermal responsiveness, and surface bioactivity. Reinforcement with ZrO2 enables real‐time x‐ray visibility and mechanical robustness, while a polydopamine coating facilitates near‐infrared‐triggered drug release and modulates cell migration, thereby ...

In-Plane Heatwave Thermography as Digital Inspection Technique for Fasteners in Aircraft Fuselage Panels

Applied Sciences, 2020
The inspection of fasteners in aluminium joints in the aviation industry is a time consuming and costly but mandatory task. Until today, the manual procedure with the bare eye does not allow the temporal tracking of a damaging behavior or the objective ...

Sizing Wedge Delaminations Using Lock-in Thermography

Journal of Nondestructive Evaluation
Abstract Sizing hidden defects is a major challenge in many industries. In the last years we have successfully used optically excited lock-in infrared thermography to size the geometrical parameters of both infinite and semi-infinite uniform delaminations.

Lock-in thermography and fatigue limit of metals

Proceedings of the 2000 International Conference on Quantitative InfraRed Thermography, 2000
Thermography was performed on stainless steel 316L and aluminium alloy 7010 samples as they were submitted to a sinusoidal mechanical stress (traction/compression). For each stress amplitude value the temperature data were recorded in 5 s. A specific signal demodulation procedure was used to extract the first two Fourier components and the mean ...

Anisotropy Thermal Properties of Electrically Insulating Thin Films and Sheets: A Review

Small Methods, EarlyView.
Thermally conducting and electrically insulating materials with anisotropy properties play an integral role in advanced thermal management, in particular for electronic devices. This review discusses recent progress in enhancing thermal conductivity and controlling the thermal anisotropy between in‐plane and cross‐plane (through‐thickness) directions ...

Detection of composite damage by IR NDT using ultrasonic and optic excitation

MATEC Web of Conferences, 2019
The submitted paper presents experience with detection of damaged composites by means of an ultrasonic excitation system in comparison with an optic system of excitation. In case of the ultrasonic excitation system is a high-frequency signal modulated by

A Comparative Study of Directed Energy Deposition‐Arc and Casting: Enhancing Mechanical and Thermal Properties of Hot‐Work Tool Steels

steel research international, EarlyView.
The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.

Surface Micro‐Discharge Plasma for Multiple Teeth Bleaching: Efficacy, Mechanism and Safety

High Voltage, EarlyView.
ABSTRACT Hydrogen peroxide (H2O2) is the commonly‐used bleaching chemical in clinical practice, but its excessive concentrations can cause tooth damage. Atmospheric pressure cold plasma is considered a promising new technique for tooth bleaching. Surface micro‐discharge (SMD) devices can generate large‐scale plasma, which holds potential for treating ...

Basal body temperature as a biomarker of reproductive state in ewes: A multi‐method comparison

Australian Veterinary Journal, EarlyView.
This study quantified body temperature dynamics throughout reproductive stages in crossbred ewes based on complementary monitoring techniques. Five ewes from a semi‐extensive farming system were included in two sub‐trials: animals were first assessed in the prepubertal stage and, subsequently, an oestrous cycle was induced by intravaginal progesterone ...
