Abstract Background The differential immune responses after two additional BNT162b2 (BNT) doses between ChAdOx1 nCoV-10 (ChAd)-primed and BNT-primed groups have not been elucidated. The aim of this study was to compare vaccine-induced humoral and cellular immune responses and evaluate breakthrough ...

Statistical Evaluation of Barkhausen Noise Testing (BNT) for Ground Samples [PDF]
Sensors, 2019 Barkhausen noise testing (BNT) is a nondestructive method for investigating many properties of ferromagnetic materials. The most common application is the monitoring of grinding burns caused by introducing locally high temperatures while grinding. Other features, such as microstructure, residual stress changes, hardening depth, and so forth, can be ...

The goal of this study was to investigate the effect of varied proportions of silica/M-BNT/BNT on the curing properties of natural rubber (NR) composites. Thirteen ternary-filled NR composites and a control sample were prepared in this study based on a third degree – simplex lattice mixture design of experiment.

BNT ceramics synthesis and characterization
Materials Science and Engineering: B, 2004Abstract Investigations on barium neodymium titanate (BNT) prepared by solid state reaction techniques are presented in this paper. The samples were sintered at temperatures, T s , in a range 1200–1300 °C. High density values and adequate microwave parameters were obtained by adding 0.5 mol PbO substitutional for BaO.

Abstract Dielectric and ferroelectric properties of 0.93Bi 0.5 Na 0.5 TiO 3 –0.07BaTiO 3 (BNT–BT) and 0.93Bi 0.5 Na 0.5 TiO 3 –0.06BaTiO 3 –0.01K 0.5 Na 0.5 NbO 3 (BNT–BT–KNN) ceramics were studied in detail. An XRD analysis confirmed the single perovskite phase formation in both the samples. Room temperature (RT) dielectric constant ( e r ) ~1020

Cycling stability of lead-free BNT–8BT and BNT–6BT–3KNN multilayer actuators and bulk ceramics
Journal of the European Ceramic Society, 2014This study presents the electromechanical properties and cycling stability of lead-free piezoelectric materials 0.92(Bi1/2Na1/2)TiO3–0.08BaTiO3 (BNT–8BT) and 0.91(Bi1/2Na1/2)TiO3–0.06BaTiO3–0.03(K0.5Na0.5)NbO3 (BNT–6BT–3KNN). Both bulk samples as well as multilayer actuators (MLA) with internal Ag/Pd (70/30) electrodes were successfully processed from ...
