Cycling stability of lead-free BNT–8BT and BNT–6BT–3KNN multilayer actuators and bulk ceramics

Journal of the European Ceramic Society, 2014
This 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 ...

Synthesis and characterization of BNT thin films

, 2014
Polycrystalline piezoelectric lead-free Bi0.5Na0.5TiO3 (abbreviated as BNT) thin films were deposited on glass substrates by an optimized Sol-Gel process using the Electrospray technique. X-ray Diffraction (XRD) analysis showed that after heating the films at 650˚C for 1 hour, dense and well crystallized BNT films in the rhombohedral perovskite phase ...

Boston Naming Test with Latencies (BNT-L) [PDF]

, 2007
Although most people have experienced word-finding difficulty at one time or another, there are no clinical instruments able to reliably distinguish normal age-related effects from pathology in word-finding impairment. Two experiments were conducted to establish a modified version of the Boston Naming Test (BNT) that includes latency times, the Boston ...

Influence of Hydrothermal Synthesis Conditions on BNT-Based Piezoceramics

Journal of the European Ceramic Society, 2011
International audienceThe Bi0.5Na0.5TiO3 perovskite (BNT) is a very promising lead-free candidate for piezoelectric applications. Nevertheless a low reproducibility is commonly reported for the solid state synthesized BNT.

B-071 Comparison of Humoral and Cellular Immune Responses Between ChAd-BNT Heterologous Vaccination and BNT-BNT Homologous Vaccination Following the third BNT Dose: A Prospective Cohort Study

Clinical Chemistry, 2023
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 ...

Effect of Silica/M-BNT/BNT Ternary Filler Loading on the Curing Properties of Natural Rubber Vulcanizates

Materials Science Forum, 2023
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, 2004
Abstract 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.
