Effect of sintering temperature of NBT–6BT lead-free ceramics on the structural, ferroelectric and piezoelectric properties
منشور في 2022"…It is found that the optimal ferroelectric and piezoelectric values were obtained at 1150 °C (P r = 27 µC/cm 2 , E c = 3.89 kV/mm and d 33 = 110 pC/N). According to these results, we suggest that 850 °C and 1150 °C can be considered as optimal calcination and sintering temperature in NBT-6BT ceramic, respectively.…"

Role of Edge Groups in Defining the Stability of Aromatic Molecules Under Electron Irradiation
منشور في 2024"…<p dir="ltr">Electron irradiation is known to be an important physical tool in tuning the properties of self-assembled organic molecules. Here, we use X-ray photoelectron spectroscopy (XPS) measurements to study the effect of electron bombardment on the structural properties of dithiol aromatic molecules, where the sulfur atoms are either in direct conjugation with phenyl rings (case of Biphenyl-4,4′-dithiol, BPN) or separated by a methylene group (case of 5,5′-bis(mercaptomethyl)-2,2′-bipyridine, BPD). …"
