Colloidal synthesis and photocatalytic properties of orthorhombic ...
2014年5月12日 AgGaS 2 (AGS) nanocrystals that exist in the orthorhombic phase were successfully prepared for the first time through a one-pot colloidal synthetic strategy using suitable coordinating solvents. These orthorhombic AGS nanocrystals were found to display great potential in visible-light-driven photocatalysis.
Density functional theory for calculation of elastic
2024年3月29日 constants of the orthorhombic C54 structure TiSi2 have re- cently been determined experimentally. 2 This motivated us to calculate all nine independent elastic constants and related

New orthorhombic sodium iron(+2) titanate - ScienceDirect
2020年3月1日 The set of compositions with Fe 2+ in the system Na x Fe x/2 Ti 2–x/2 O 4 has been prepared by solid-state reactions in the inert atmosphere at 1050 °С. The oxidation state of iron was confirmed using the XANES method. Na 0.88 Fe 0.44 Ti 1.56 O 4 is the new four-element compound in Na 2 O–“FeO”–TiO 2 system. According to the X-ray
Crystal System: Orthorhombic Crystal Class/Point Group (Hermann-Mauguin notation): 222 Crystal Class/Point Group (Schönflies notation): D2 Symmetry: 3A2 Name of Class: Rhombic-disphenoidal Notes: In this class there are 3 2-fold axis and no mirror planes. The 2-fold axes are all perpendicular to each other. The disphenoid faces that define this
2021年3月19日 Here, we report the stabilization of highly epitaxial orthorhombic mm2 BTO with in-plane polarization using strain engineering. By inserting the appropriate thickness of a strain control layer of BaSnO 3 (BSO) that has a larger lattice constant than BTO, an orthorhombic, single domain, in-plane polarized BTO layer can be formed.
