Micro‐Layer and Lattice Structure Effects on Impedance of Titanium Oxide Phthalocyanine

Abstract

In this study, the authors employ synchrotron techniques to characterize multi‐scale microstructure in elucidating how the modified crystal lattices at angstrom level and molecular stacking at micrometer scale of titanium oxide phthalocyanine (TiOPc) thin film tuning the impedance. The a and c lattice lengths of the TiOPc reveal a positive correlation with the impedance because of the π‐π stacking distances of TiOPc molecules arrangements. Our results suggest a promising dip coating method to tailor the charge storage capability of TiOPc through controlling the crystal lattice sizes of TiOPc.

Multi-Scale Microstructure Investigation for a PM2.5 Air-Filter Efficiency Study of Non-Woven Polypropylene

“…TXM tomography was carried out at beamline (BL) 01B1, National Synchrotron Radiation Research Center (NSRRC) in Taiwan with the wavelength of 1.54 Å (8 keV) and spatial resolution of 60 nm. The protocol is archived [19,20]. TXM can construct 3D geometric configuration of materials by capturing a series of 2D X-ray radiographies from different viewing angles.…”

Investigation of Bone Growth in Additive-Manufactured Pedicle Screw Implant by Using Ti-6Al-4V and Bioactive Glass Powder Composite

“…We conducted TXM—a nondestructive image microscopy technique—at the wavelength of 1.54 Å (8 keV) with a spatial resolution of 60 nm at the beam line (BL) 01B1, National Synchrotron Radiation Research Center (NSRRC) in Taiwan. The evident contrasts of two-dimensional (2D) TXM images provided a clear differentiation of the developing areas of immature bone, mature bone, and void to the naked eye [ 28 , 56 , 57 ]. The surface area of bone ingrowth was determined as the ratio between the surface area of immature bone, mature bone, or void and the total area of bone ingrowth.…”
