Abstract. Y-junctions and related carbon nanotube (CNT) junctions were synthesized by Au-catalyzed chemical vapor deposition. The catalyst was prepared by evaporating a 10-nm-thick Al2O3 film and a 1-nm-thick Au film on a Si substrate. Based on thorough investigations under a high-resolution transmission electron microscope, the CNT junctions were proved to be formed by a unified catalyst-merg…
Abstract. Bi2O3 nanofibers with diameter of 70–200 nm were successfully prepared by electrospinning a precursor mixture of polyacrylonitrile (PAN)/bismuth nitrate, followed by calcination treatment of the electrospun polymer/inorganic composite fibers. The resulting Bi2O3 nanofibers were characterized with X-ray diffraction, X-ray photoelectron spectroscopy, scanning electron microscopy, …
