spectroscopy (XPS) also confirmed the presence of metal element Gd with characteristic binding energy at 148.00 eV (Gd 4d3/2) and Fe with characteristic binding energy at 711.75 eV (Fe 2p3/2), consistent with standard XPS spectrum of Gd3+ and Fe3+ (NIST XPS Database), ...
(B) Scheme of a tapered fiber with a 500-nm diameter waist for ultrasensitive gas absorption spectroscopy. (C) Spectral investigation of the film ripening. Spectra for t = 20–100 s can be modeled as a weighted sum of the spectra at t = 20 s and t = 100 s. The dotted line extrapo...

Electrochemical impedance spectroscopy (EIS) tests were conducted in a solution of 4 mM Fe(CN)63−/Fe(CN)64− in 1 M KCl with an AC amplitude of 0.1 V. An initial DC potential of 0.25 V was applied with a frequency range of 1–100,000 Hz [41,49,59]. Complex plane diagrams (...
The Raman structure test of the methane hydrate sample was performed at 193 K before the decomposition of the sample started. During the decomposition, the methane hydrate sample was controlled at 263 K, 253 K, and 245 K by the cooling stage. Scanning Raman spectroscopy for one pass took ...
