Journal ArticleDOI
Photocatalytic decomposition of water into hydrogen and oxygen over nickel(II) oxide-strontium titanate (SrTiO3) powder. 1. Structure of the catalysts
TL;DR: The structure of NiO-SrTiO/sub 3/ powder has been studied by spectroscopic methods such as SEM, TEM, EXAFS, XANES, and XPS as mentioned in this paper.
Journal ArticleDOI
Electron energy loss and X-ray absorption spectroscopy of rutile and anatase: a test of structural sensitivity
TL;DR: In this paper, the electron energy loss and X-ray absorption spectra of two phases of titanium dioxide-rutile and anatase-were reported, and the authors proposed an interpretation of the Ti L2.3 edge, notably for the presence of a previously unobserved splitting on the L3 edge.
Journal ArticleDOI
Efficient methods for solving the open-shell scf problem and for obtaining an initial guess. The “one-hamiltonian” and the “partial scf” methods
Nobuhiro Kosugi,Haruo Kuroda +1 more
TL;DR: The one-hamltonian method combined with the partial SCF method for obtaining an initial guess of the orbitals is tested on open-shell restricted SCF calculations of the 2 Σ + state of PO and several excited states of o 3 as discussed by the authors.
Journal ArticleDOI
Highly Efficient 2D/3D Hybrid Perovskite Solar Cells via Low-Pressure Vapor-Assisted Solution Process.

TL;DR: The dimensionality of the as-fabricated perovskite film reveals an evolution from 2D, hybrid 2D/3D to 3D structure when the doping level of PEAI/PbI2 ratio varies from 2 to 0.05, which suggests the coexistence of low-dimensional perovSKite (PEA2 MAn-1 Pbn I3n+1 ) with various values of n after vapor reaction.
Journal ArticleDOI
Polarized Cu K-edge XANES of square planar CuCl42− ion. Experimental and theoretical evidence for shake-down phenomena
TL;DR: In this article, the origin of the shoulder structure in the X-ray absorption spectra of a single crystal of (creatinium)2CuCl4 was found to be exclusively polarized in the direction normal to the molecular plane of the CuCl42− ion.
