In this study, the feasibility of using a one dimensional 16-element flexible ultrasonic transducer (FUT) array for nondestructive testing at 150 °C is demonstrated. The FUT arrays were made by a sol-gel sprayed piezoelectric film technology; a PZT composite film was sprayed on a titanium foil of 75 µm thickness. Since the FUT array is flexible, it was attached to a steel pipe with an outer di...

The backfill quality of a pipeline has an important influence on operation. When loose is used, the may be damaged after short term In this study, numerical simulation analysis buried pipes was carried out under three conditions: around pipe, dense backfill, and controlled low strength materials (CLSM) backfill. effects narrow trench backfilling using CLSM force deformation pipelines were studi...

Nonwoven meshes of polyglycolic acid (PGA) fibers are attractive synthetic extracellular matrices (ECMs) for tissue engineering and have been used to engineer many types of tissues. However, these synthetic ECMs lack structural stability and often cannot maintain their original structure during tissue development. This makes it difficult to design an engineered tissue with a predefined configur...
