Since the beginning of the applications of non-destructive testing/evaluation (NDT/NDE)
techniques, efforts have been made consistently to improve their detection sensitivity and …

A 100-MHz ultrasonic linear transducer array made from a piezoelectric zinc oxide thin film
on a sapphire substrate was developed and evaluated. Epitaxial, high-acoustic quality 10 …

Non-destructive testing (NDT) is an important tool for defect detection in composite
materials. Compared to other NDT methods, ultrasonic testing (UT) has the principal …

We report on the conversion of ultrasound into light by the process of piezo-luminescence in
epoxy with embedded BaSi 2 O 2 N 2: Eu as active component. We exploit this acoustically …

Quantitative evaluation of ultrasonic C-scan images in homogeneous and layered
anisotropic austenitic materials is of general importance for understanding the influence of …

The present paper proposes a non-contact ultrasonic testing method for the debonding
inspection of metal-based composite structures, utilizing an improved electromagnetic …

Ultrasound measurement is a relatively inexpensive and commonly used imaging tool in the
health sector. The through-transmission process of ultrasound measurement has been …

An ultrasonic material characterization method is proposed to reconstruct the polycrystalline
microstructures from the field-measurement of ultrasonic surface waves. Two wavenumber …

Lung ultrasound is an increasingly utilized non-invasive imaging modality for assessing lung
condition but interpreting it can be challenging and depends on the operator's experience …

The main challenges for Al-Al wafer bonding are the fast oxidation and the high roughness
of the Al surface. This paper describes an optimized Al sputter-deposition process reducing …
