Gallium and thallium NMR study of phase transitions and incommensurability in the layered semiconductor TlGaSe2
Panich, AM; Ailion, DC; Kashida, S; Hasanlı, Nızamı (American Physical Society (APS), 2004-06-01)
We report on the first NMR study of phase transitions and incommensurability in the layered semiconductor TlGaSe2. Ga-69,Ga-71 and Tl-205 NMR data from a powder sample show phase transitions at 118, 108 and around 69 K. The Ga-69 and Ga-71 spin-lattice relaxation times T-1 are short and nearly temperature independent in the temperature range 118 to 108 K, which is characteristic of an incommensurate state. The nuclear magnetization recovery in this temperature range can be fit by two components having diffe...
Germanium nanowire synthesis using solid precursors
AKSOY, Burcu; Kalay, Yunus Eren; Ünalan, Hüsnü Emrah (2014-04-15)
We report on the synthesis of single crystalline, high aspect ratio germanium (Ge) nanowires (NWs) by vapor transport method using three different solid powder precursors. Investigated precursors were either powder like germanium or powder mixtures like germanium dioxide with carbon and germanium iodide with germanium. As-grown NWs were analyzed using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-Ray diffraction (XRD) and X-Ray photoelectron spectroscopy (XPS) to obtain struc...

© 2021 The Authors. Legume Science published by Wiley Periodicals LLC.The main aim of the article was to produce gallic acid-loaded pea flour/polyethylene oxide (PEO)-based nanofibers through the electrospinning method as an alternative active packaging material. Incorporation of gallic acid caused significant changes in both solution properties and fiber morphology. Increasing gallic acid concentration resulted in increasing conductivity and decreasing consistency index, by the way decreasing average fiber...
