The chemical composition of the Na–Mt was determined by the X-ray fluorescence (XRF) method on the X-ray fluorescence spectrometer, Rigaku ZSX Primus. Small-angle X-ray diffraction tests were carried out on a Rigaku Smartlab SE with a Cu-Kα (λ = 0.154 nm) X-ray source at 40 kV and 40 mA. The scanning test range is 1.5° to 10° (2θ), and the scanning rate is 1° min−1. FTIR spectra were recorded in the 4000–400 cm−1 region on an Affinity-1S spectrophotometer using the KBr compression method. The surface morphology of the sample was observed under a scanning electron microscope (TESCAN MIRA LMS) after it was coated with gold thin films. The zeta values of Na–Mt and of CTMAB–Mt were obtained by using a Malvern Nano-ZS90.

X-ray diffraction (XRD, D8 Advance, Bruker, Cu Kα radiation at a fixed incident angle of 2°), X-ray photoelectron spectroscopy (XPS, PHI 5000 VersaProbe with an Al Kα source (Sigma Probe, VG Scientific)), Raman spectroscopy (inVia Raman Microscope), and Fourier transform infrared (FTIR, Nicolet iS50, Thermo Fisher) spectroscopy measurements were carried out. The morphology and composition of the samples were investigated using field emission-scanning electron microscopy (FE-SEM, SUPRA 55VP, Carl Zeiss AG), transmission electron microscopy (TEM, JEOL JEM-2100F), energy-dispersive X-ray spectroscopy (EDX). The analysis for a composition of the as-prepared GaHCCo was also carried out using thermogravimetric analysis (TGA) which was performed under N2 flow from room temperature to 700 °C with a temperature ramp of 10 °C min−1, as well as X-ray fluorescence measurements (XRF, ZSX-PRIMUS, Rigaku). Quantitative measurements were achieved by using inductively coupled plasma (ICP) for Ga, Co, and K elements and EA(CHNS) analysis for C, H, and N elements.

The phase and crystallinities of the N-Si alloy powders, coated with Al2O3 using ALD, were analyzed using XRD (D8, Bruker AXS, Karlsruhe, Germany) with Cu-Kα (wavelength: 0.15418 nm). The exposure time was 2.5 s at each step, and the scanning was performed in the range of 2θ = 10–60° with an interval of 0.45°. The morphology of the coated N-Si alloy powder was analyzed using field-emission SEM (JSM-6701F, JEOL, Tokyo, Japan) and field emission gun TEM (JEM-ARM200F, JEOL, Japan). Focused Ion Beam (FIB-FB2100, Hitachi, Japan) treatment was performed to observe the cross section of the powder. The compositions of the powders were identified using the XRF technique (ZSX Primus, Rigaku, Japan), and the powder-particle sizes were analyzed using a laser diffraction particle size analyzer (Mastersizer 2000, Malvern, UK). Furthermore, a BET analyzer (BET-Micromeritics ASAP2020, Norcross, GA, USA) was applied to evaluate the specific surface area and pore size distribution of the synthesized coated N-Si alloy powders.

The brick used in this experiment came from Kaifeng City, Henan Province. It was a gray brick which had been discarded following the demolition of old residential buildings, and was steel-gray in color. Through using an X-ray diffractometer (Rigaku D/max 2400; Rigaku, Japan), its main mineral components were found to be quartz, anorthite, albite and microplagioclase. The chemical compositions of gray brick were obtained using X-ray fluorescence spectrometer (Rigaku ZSX Primus; Rigaku, Japan); the results are shown in Table 1 .

The element ratios of La, Mn, and Ti for the samples were confirmed by using X-ray fluorescence spectroscopy (XRF; Rigaku, ZSX Primus). The crystal structure of the samples was identified by X-ray powder diffraction (XRD; Rigaku, Ultima IV) with Cu-Kα radiation, operating with voltage and current settings of 40 kV and 40 mA. The lattice parameters and volumes were calculated from the XRD peak angles refined, using α-Al2O3 as a standard and using the CellCalc Ver. 2.20 software. The morphologies and particle sizes were observed by using field-emission-type scanning electron microscopy (FE-SEM; JEOL, JSM-6701F).
The optical reflectance spectra were measured with a UV-Vis-NIR spectrometer (JASCO, V-770), using a standard white plate as a reference. The color properties were evaluated in terms of the Commission Internationale de l’Éclairage (CIE) L*a*b*Ch° system, using a colorimeter (Konica-Minolta, CR-300). The L* parameter represents the brightness or darkness in a neutral grayscale. The a* and b* values indicate the red–green and yellow-blue axes, respectively. The chroma parameter (C) expresses the color saturation and is calculated with the formula, C = [(a*)2 + (b*)2]1/2. The hue angle (h°) ranges from 0 to 360° and is estimated according to the following formula: h° = tan−1(b*/a*).

Bagasse fly ash was collected from a local sugar factory in Thailand. As-received ash was used to extract silica. The microstructure of bagasse ash was studied using a scanning electron microscope (SEM, Leo 1450VP, gold coating). Oxide compounds were analyzed by X-ray fluorescence spectrometry (XRF, Rigaku ZSX Primus). Loss on ignition (LOI) was calculated from the weight loss of the ash heated at 950 ± 50 °C for 15 min according to ASTM C114-15: Standard test methods for chemical analysis of hydraulic cement. A morphological study was carried out using X-ray diffraction spectroscopy (XRD, Rigaku MiniFlex).
1M hydrochloric solution (HCl) and 2.5 M HCl were used as the acid solutions for ash pre-treatment and silica precipitation, respectively. 1 M sodium hydroxide solution (NaOH) was prepared for the extraction of silica from bagasse ash. In addition, photochromic reversible pigment (white to magenta) and basecoat binder were purchased from international suppliers.

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.
