Scanning acoustic microscopy as a non-destructive imaging tool to localize defects inside battery cells

Journal of Power Sources Advances, 2020
Scanning Acoustic Microscopy (SAM) is shown here for the first time to be suitable for the visualization of defects like electrolyte leakage, faulty electrodes and gas accumulation inside coin and pouch battery cells.

Modification of Olive Leaves’ Surface by Ultrasound Cavitation. Correlation with Polyphenol Extraction Enhancement

Applied Sciences, 2020
We investigated the impact of ultrasound at 20 kHz on olive leaves to understand how acoustic cavitation could increase polyphenol extraction. Application of ultrasound to whole leaf from 5 to 60 min enabled us to increase extraction from 6.96 to 48.75 ...

Acoustically Stimulated Charge Transport in Graphene Film

Nanomaterials, 2022
The process of acoustically stimulated charge transport in the graphene film on the surface of the YZ−cut of a LiNbO3 crystal was investigated. It was found that the dependence of the current in the graphene film on the frequency of the surface acoustic ...
