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 ...

Multi‐Scale 3D Printing of Magnetic Polymer Nanocomposites with Controlled Particle Dispersion and Hyperthermic Response

Small, EarlyView.
Dispersion of magnetic nanoflowers in trimethylolpropane ethoxylate triacrylate to generate photocurable nanocomposites is described. Particle dispersion provides processability and target AC‐field stimulated temperature increases. Complex (DLP) printed structures with submicron features are demonstrated, and the potential for stimulated release of ...

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 ...

Research on Self‐Identification Technology of Zero‐Value Insulators in Distribution Lines Based on Electroluminescence Effect

High Voltage, EarlyView.
ABSTRACT To address the issue of low detection accuracy for zero‐value insulators in distribution lines, this study proposes a novel method for detecting these insulators based on the electroluminescence effect. Through theoretical analysis and experimentation, it was found that the luminescence intensity of ZnS:Cu electroluminescent material varies ...
