Published in 2021 at "Advanced materials"

DOI: 10.1002/adma.202102471

Abstract: Heterostructure construction is an efficient method for reinforcing K+ storage of transition metal selenides. The spontaneously developed internal electric fields give a strong boost to charge transport and significantly reduce the activation energy. Nevertheless, perfection… read more here.

Published in 2018 at "Journal of Materials Science: Materials in Electronics"

DOI: 10.1007/s10854-018-9559-1

Abstract: Structure and electrical properties of Mn-doped (0.6 − x)Pb(Mg1/3Ta2/3)O3–xPbZrO3(PZ)–0.4PbTiO3 (PMT–PZ–PT) ceramics with morphotropic phase boundary were studied (x = 0.2 and 0.25). The tetragonal intensity ratio TP (%) of Mn doped 0.4PMT–0.2PZ–0.4PT samples was calculated based on Raman spectra.… read more here.

Published in 2019 at "Acta Materialia"

DOI: 10.1016/j.actamat.2019.03.035

Abstract: Abstract Solid-solid phase boundary anisotropy is a key factor controlling the selection and evolution of non-faceted eutectic patterns during directional solidification. This is most remarkably observed during the so-called maze-to-lamellar transition. By using serial sectioning,… read more here.
