Title Atomic-scale identification of novel planar defect phases in heteroepitaxial YBa2Cu3O7-\delta thin films Type A1 Journal article
Year (down) 2018 Publication AIP advances Abbreviated Journal Aip Adv
Volume 8 Issue 5 Pages 055022
Keywords A1 Journal article; Engineering sciences. Technology; Electron microscopy for materials research (EMAT)
Abstract We have discovered two novel types of planar defects that appear in heteroepitaxial YBa2Cu3O7-delta(YBCO123) thin films, grown by pulsed-laser deposition (PLD) either with or without a La2/3Ca1/3MnO3 (LCMO) overlayer, using the combination of highangle annular dark-field scanning transmission electron microscopy (HAADF-STEM) imaging and electron energy loss spectroscopy (EELS) mapping for unambiguous identification. These planar lattice defects are based on the intergrowth of either a BaO plane between two CuO chains or multiple Y-O layers between two CuO2 planes, resulting in non-stoichiometric layer sequences that could directly impact the high-Tc superconductivity.

Title Multimodal zeolite-beta-based catalysts with a hierarchical, three-level pore structure Type A1 Journal article
Year (down) 2011 Publication Chemsuschem Abbreviated Journal Chemsuschem
Volume 4 Issue 10 Pages 1452-1456
Keywords A1 Journal article; Electron microscopy for materials research (EMAT)
Abstract Hole diggers: The hierarchically structured porous solid-acid catalyst described in this report possess a remarkable pore system, encompassing well-defined macrochannels, interconnected mesopores, intracrystalline mesopores, and tunable zeolite micropores. Importantly, the catalyst exhibits very strong acidity and superior catalytic activity for esterification reactions.
