Designing lead-free piezoelectric ceramics with tailored electrical properties remains a critical challenge for various applications. In this paper we present a novel methodology integrating Machine Learning (ML) and optimization procedures to fine-tune electrical properties in lead-free (1-x) Na0.5 …

Vibrational and structural properties of lead-free piezoelectric (1-x)Na0.5Bi0.5TiO3–xCaTiO3 (0 < x < 1.00) solid solutions have been investigated using Raman spectroscopy and X-ray diffraction. Different anomalies were detected and analyzed taking into consideration the phase transition from rhombohedral …

Het aantonen of corrosie gedetecteerd kan worden in de omtrek richting van pijpleidingen. Er wordt gebruik gemaakt van zeer dispersieve akoestische plaatgolven genaamd Lamb waves. Als transducers worden er Elektro-Magnetische Akoestische Transducers gebruikt. Corrosion inside pipelines caused by salt …
