The reflective spectra of the dual-mode device in heating and cooling modes were measured by using an ultraviolet-visible near-infrared spectrophotometer (Cary 5000, Agilent) with a calibrated integrating sphere and a Fourier transform infrared spectrometer (Frontier Optica, Perkin Elmer) with an integrating sphere (MCT Mid-IR Integrated Sphere, Pike). The absorptivity/emissivity (α/ε) was calculated using 100% reflectivity (0% transmissivity determined by Al foil). Temperature-dependent XRD data were measured by X-ray powder diffraction instrument (Smart Lab SE, Rigaku) with a homemade proportional-integral-derivative (PID) temperature control setup. Optical and infrared images were captured by an optical camera (FDR-AXP55, Sony) and an infrared camera, respectively.

Check if the same lab product or an alternative is used in the 5 most similar protocols
The phase composition of immobilized catalysts before and after use was studied by XRD analysis using a Rigaku SmartLab SE X-ray powder diffractometer with Cu Kα radiation (λ = 0.154 nm) for phase identification. Full pattern identification was carried out by a SmartLab Studio II software package, version 4.2.44.0 by Rigaku Corporation (Tokyo, Japan). Materials identification and analysis were performed by the ICDD base PDF-2 Release 2019 (Powder Diffraction File, ver. 2.1901). XRD patterns were obtained using 40 kV, 30mA by Θ/2Θ (Bragg-Brentano geometry) in the 2Θ range of 10–90° (step size 0.03° and speed 4°/min). The XRD measurements were performed for both freshly synthesized and used matrices, when the latter were separated from the reaction mixture and dried.

All electrochemical experiments were performed on an electrochemical
workstation (CHI 6095E Instruments Austin, TX) with a conventional
three-electrode system, in which the paraffin-impregnated graphite
electrode (PIGE) was used as the working electrode, a platinum electrode
was employed as the counter electrode, and a saturated calomel electrode
(SCE) was used as the reference electrode. For the impedance study,
the applied potential was 0.3 V and was recorded with an amplitude
of 5 mV over the frequency range of 0.1 Hz to 100 kHz. All electrochemical
studies were carried out at room temperature (25 °C). The synthesized
compound was characterized by SEM, UV–vis, FT-IR, TGA and DTA,
XRD, and XPS techniques. SEM was recorded with a Quattro S Instrument,
ThermoFisher Scientific; FT-IR spectra were recorded with an AGILENT
Instrument; UV–vis spectra were recorded with a JAZ, Ocean
optics; TGA–DTA curves were recorded with a FTA2500 Instrument,
Netzsch; XRD spectra were recorded with a SmartLab SE X-Ray Instruments,
Rigaku; and XPS spectra were recorded with a ULVAC-PHI Versaprobe-II.

Check if the same lab product or an alternative is used in the 5 most similar protocols
The structural characteristics of the co-sputtered ScSZ films were determined with an X-ray powder diffractometer (SmartLab SE, Rigaku, Tokyo, Japan) with Cu-Kα radiation (λ = 1.5460 Å). The XRD patterns were registered in 2θ geometry (angle of incidence 3°) in the range of 20–80° with a step of 0.03° and a rate of 0.5°/min. The phase analysis was performed using SmartLab Studio II ver. 4.2.44.0, using the Rietveld Refinement method in the 20–70° range. The crystallite size and lattice parameter were calculated using the Comprehensive Analysis module and the Halder–Wagner modeling method. The films’ thickness, surface morphology, and chemical composition were revealed with scanning electron microscopy (SEM) MAIA3 (TESCAN, Brno, Czech Republic) equipped with an X-ray energy dispersive spectrometer (EDS) X-MaxN (Oxford Instruments, Abingdon, UK). Auger Electron Spectroscopy (AES) EG3000, CMA2000 (LK Technologies, Maple Heights, OH, USA) was applied in conjunction with argon remote plasma treatment to estimate the surface stoichiometry of the ScSZ films. The specific masses of the deposited films were evaluated via the gravimetric method [46 ] with the analytical balance BM-5 (A&D Company Limited, Tokyo, Japan).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
