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...

Results of studying the domain structure planar Ni microparticles formed on single-crystal substrates from lithium niobate and potassium titanyl phosphate at different temperatures are presented. The dependence sizes sample temperature was studied. It is shown observed change caused by magnetoelastic effect, which arises due to difference in thermal expansion coefficients substrate as changes. ...

Abstract We perform a theoretical analysis of the structural and electronic properties sodium potassium niobate K $$_{1-x}$$ 1 - x Na $$_{x}$$ NbO $$_{3}$$ 3 in orthorhombic room-temperature phase, ba...

• An ultrahigh W Rec of 8.09 J·cm ?3 was achieved at the optimum composition x = 0.15 under electric field 870 kV·cm ?1 . Such high accompanied by a energy storage efficiency ( ? ) 88.5%, which is superior to that other KNN-based bulk ceramics and very important for practical applications. The findings in this work provide significant designing strategy exploring series new high-performance lea...

Using the history dependence of a dipolar glass hosted in a compositionally disordered lithium-enriched potassium tantalate niobate (KTN:Li) crystal, we demonstrate scale-free optical propagation at tunable temperatures. The operating equilibration temperature is determined by previous crystal spiralling in the temperature/cooling-rate phase space.

After a 20 min initial washout, the rate of loss of radioactively labeled sodium ions from sodium-enriched muscle cells is sensitive to the external sodium and potassium ion concentrations. In the absence of external potassium ions, the presence of external sodium ions increases the sodium efflux. In the presence of external potassium ions, the presence of external sodium ions decreases the sod...
