Hace 3 días · Electron energy-loss spectroscopy (EELS) allows for imaging a sample’s core electronic structure and mapping its chemical elements. And cryoelectron microscopy—the development for which the 2017 Nobel Prize in Chemistry was awarded—enables researchers to determine the high-resolution structure of biomolecules in a cryogenic state (see Physics Today , December 2017, page 22 ).
Hace 3 días · The microstructural characteristics of the matrix were examined using optical, scanning and transmission electron microscope (OM, SEM and TEM). High resolution transmission electron microscope (HRTEM) along with electron energy loss spectrum (EELS) mode was employed to understand the type of carbide particles formed.
Hace 4 días · EELS detected the water oxygen peak (537 eV) of water confined by CNT 10 as shown in fig. S15. The H-bonding structure of confined water within CNT 10 was radially examined in three sections (sections are overlaid on a TEM in Fig. 3A ).
Hace 1 día · Regarding the interface with Ni, a study on Ni film deposition on yttria-stabilized zirconia (111) using EELS revealed O termination at the Ni–ZrO 2 interface , while Zr termination was reported for the interface formed by the reduction of NiO–ZrO 2 from TEM and EELS observations and for Ni–ZrO 2 composite plating, where the reduction of Zr4+ was observed by XPS .
Hace 4 días · We employ analytical transmission electron microscopy (TEM) to correlate the structural and chemical environment variations within a stacked epitaxial thin film of the high entropy oxide (HEO) Mg0.2Co0.2Ni0.2Cu0.2Zn0.2O (J14), with two layers grown at different substrate temperatures (500 and 200 °C) using pulsed laser deposition (PLD). Electron diffraction and atomically resolved STEM ...
Hace 5 días · The present work reports a comparative study on CuO and 3.0% Mn-doped CuO nanofibers (NFs) produced by the electrospinning method. State-of-the-art characterization techniques such as Electron Energy Loss Spectroscopy (EELS) and X-Ray photoelectron Spectroscopy (XPS) have been employed to determine the multivalent states and elucidate their electronic structure at the Cu-L3,2 (2p) edge.
Hace 2 días · The polyol synthesis of CoO nanoparticles (NPs) is typically conducted by dissolving and heating cobalt acetate tetrahydrate and water in diethylene glycol (DEG). This process yie
