Effect of Protective Coating Thickness on Ultrasonic Guided Wave Propagation in Plate‐Like Structures

Macromolecular Symposia, EarlyView.
ABSTRACT Ultrasonic Guided Waves (UGWs) are widely employed for the inspection and monitoring of plate‐like structures due to their long‐range propagation capability and sensitivity to structural and material changes. In real aerospace components, however, structural surfaces are commonly covered by protective layers, such as coatings or metallic films,

A Stopped‐Flow Instrument for Millisecond Timescale Reaction Monitoring on a Standard NMR Spectrometer

Magnetic Resonance in Chemistry, EarlyView.
A new stopped‐flow instrument allows kinetic measurements of reactions 10 milliseconds after initiating them by mixing in a flow cell inserted into a standard NMR probe and spectrometer. High‐speed video, pressure and NMR line‐shape data are used to characterise mixing and stopping, and a protodeboronation reaction with a 5‐millisecond half‐life used ...

The Role of Cold Atmospheric Plasma in Surface Modification and Adhesion Behavior of Polypropylene/Flax Biocomposites

Polymer Composites, EarlyView.
Effects of plasma surface treatment on adhesive bonding of PP/flax biocomposites. ABSTRACT The emphasis on environmental sustainability has accelerated the adoption of biocomposites as alternatives to synthetic composites. However, their low surface energy may limit adhesion in bonding applications.
