Effects of temperature and dose rate on ion-irradiated γ-LiAlO2 pellets
Defect accumulation and microstructural evolution during ion irradiation at elevated temperatures are governed by competing processes of defect production, driven by the dose rate, and defect recovery...
Design and development of PVDF-based hydrophone for underwater applications
Traditional ceramic-based hydrophones are exposed to low flexibility and narrow sensing band in low-frequency applications, which limits their usage in underwater acoustic sensing. To address the limi...
