Flexible piezoelectric nanogenerators for energy harvesting are getting more and attention nowadays by converting the mechanical to electric energy. Here, an environment-friendly nanogenerator based on regenerated cellulose (RC)/MoS2 nanosheet nanocomposite successfully exhibited a relative high output voltage of 2 V current 150 nA under slight press which were 5 7.5 times higher than those nea...

Recently, the need has arisen to enhance piezoelectric properties and temperature stability of (Na,K)NbO3 system ceramics. The (0.965)(Li0.03(Na0.5K0.5)0.97)(Nb1−xSbx)O3−0.035 (Bi0.5Na0.5)0.9(Sr)0.1ZrO3 ceramics were newly manufactured using sintering aids CuO, B2O3, ZnO as a function antimony substitution, their crystal structure electrical characteristics analyzed. grain size was apparently r...

This article presents a high-performance lead-free piezoelectric energy harvester (LPEH) system for magnetic field. It based on Ba0.85Ca0.15Ti0.90Zr0.10O3 + CuO 0.3 wt% (BCTZC0.3) composite was fabricated by sintering at 1450 °C. The BCTZC0.3 composite, which has an enhanced high conversion constant (d33×g33), shows improved power-generation performance when compared with conventional harvester...

The synthesis of non-lead piezoelectric ceramics (1–z)(0.65Bi1.05Fe2O3-0.35BaTiO3)-z Ba(Ti0.8Zr0.2)O3-(Ba0.7Ca0.3)TiO3 using a solid state method and quenching strategy was investigated. processing conditions such as the sintering temperature soaking time were optimized. patterns X-ray diffraction (XRD) displayed pure perovskite structure with no secondary phases. ferroelectric characteristics ...

A series of PA1111/BaTiO3 nanocomposites with different BaTiO3 contents are prepared by the in-situ salification-melt polymerization procedure. The morphological, spectroscopic studies and property characterization conducted. results indicate that proposed compositing method can effectively disperse nanoparticles in PA1111 matrix, as-prepared exhibit improved dielectric piezoelectric properties...

Ink formulation is one of the main challenges with ceramic 3D printing. Here, we present a new, reactive-colloidal hybrid ink for printing by robocasting BaTiO3-based ceramics. The combines titanium isopropoxide-based sol-gel base colloidal dispersion powder, here demonstrated BaTiO3 both as (by reaction isopropoxide and barium oxide) addition powder) parts. Addition glycerol was necessary to a...

In this paper, we review the literature on declining business dynamism and its implications in United States propose a unifying theory to analyze symptoms potential causes of decline. We first highlight 10 pronounced stylized facts related documented discuss some existing attempts explain them. then describe theoretical framework endogenous markups, innovation, competition that can potentially ...

Lead-free piezoelectric 0.92(K0.445Na0.5Li0.05)NbO3-0.08BaZrO3 (KNLN-BZ) ceramics were prepared via conventional sintering. Single-step, 2-step and 3-step temperature-controlled conditions designed. The structure electrical properties of obtained using different procedures systematically studied. It was found that ceramic the method with a holding time 20 h showed highest properties. Curie temp...

Introduction Neuropathic pain is a debilitating condition. The importance of neuroimmune interactions in neuropathic pain has been evidenced by the involvement of different immune cells in peripheral and central sensitization of pathological pain. Macrophages and microglia are the most abundant immune cells activated in injured nerves and spinal cord, respectively. Several lines of evidence sho...

Monoelemental two-dimensional (2D) materials have attracted significant attention due to their exciting electro-mechanical properties and extreme thinness. However, most of these stable centro-symmetric structures same electronegativities all atoms lack interesting such as piezoelectricity ferroelectricity. Here we report the existence in atomically thin monoelemental α-Tellurium films. DFT cal...
