Polyacrylamide-Poly(vinyl alcohol)-Sodium Alginate-Reduced Graphene Oxide/Nylon Fabrics with Multistimuli Responses

In recent years, various functional fabrics capable of responding to multistimuli have been widely recognized as promising wearable devices. However, the obtained composite functional fabrics have only been applied in a few scenarios, rendering the achievement of multifunctional wearable application scenarios a difficult goal. Therefore,...

Carriage interior noise-based inspection for rail corrugation on high-speed railway track

The presence of rail corrugation enlarges the wheel-rail impact and exacerbates the failure of track components, and the situation becomes even worse under high train speed, which promotes the urgent need for an efficient and easily accessible inspection method. Conventional diagnosis approaches such as axle box acceleration (ABA) and image...

Influence of surface pretreatment on phosphate conversion coating on AZ91 Mg alloy

Surface pretreatment is generally applied before application of protective coatings on Mg alloys, which influences surface microstructure and electrochemical activity of the substrate and has an effect on the coating properties. The effect of various pretreatment processes (sand-blasting, grinding and polishing) on the microstructure and...
