DOI: 10.1002/adma.202206425
Abstract: Piezoelectricity in low‐dimensional materials and metal–semiconductor junctions has attracted recent attention. Herein, a 2D in‐plane metal–semiconductor junction made of multilayer 2H and 1T′ phases of molybdenum(IV) telluride (MoTe2) is investigated. Strong piezoelectric response is observed… read more here.

DOI: 10.1016/j.mineng.2020.106451
Abstract: Abstract Automated mineralogy instrumentation (QEMSCAN, MLA, TIMA) is routinely used for materials characterization in the mining industry. All current techniques identify minerals based on a combination of backscattered electron and chemical (energy-dispersive spectroscopy) signals read… read more here.

DOI: 10.1063/1.5008271
Abstract: The phase boundaries within (Bi0.5Na0.5TiO3)x(BaTiO3)y(SrTiO3)1−x−y with x ≥ 0.68 have been outlined. This was achieved using a combinatorial sample fabrication method and scanning synchrotron X-ray diffraction to rapidly characterise crystallographic structures over a large region of phase… read more here.
