Particle sizes of all starting materials were determined using laser diffraction (Microtrac® MT3300SX, Nikkiso Co., Ltd., Japan) while the chemical compositions of the starting materials and synthesized geopolymers were determined by X-ray fluorescence (<50 μm loose powder) (NEXCG, Rikagu Corporation, Japan). For the ATR-FTIR spectroscopy analysis, the samples were ground manually to <10 μm using an agate mortar and pestle and then analyzed by an FT/IR-6200 HFV and ATR Pro One® attachment equipped with a diamond prism (Jasco Analytical Instruments, Japan) in the range of 400–4000 cm−1. The mineralogical compositions of the samples were identified using XRD (MultiFlex, Rigaku Corporation, Japan) on pressed powders. The samples were also analyzed by SEM-EDS (InTouchScope™, JSM-IT200, JEOL Ltd., Japan) to identify minerals and phases incorporating the toxic and hazardous elements.
Diamond prism

Sourced in Japan
A diamond prism is an optical device made of a high-refractive-index diamond material. Its primary function is to disperse white light into its constituent spectral colors by refracting the light at different angles based on the wavelength of the light.

To determine the effects of change of chemical constituents of bamboo on its antibacterial efficacy following treatment modification, Fourier transform infrared spectroscopy (FTIR) was conducted using an ATR-FTIR, FTIR-4700, and ATR PRO ONE fitted with a diamond prism (Jasco Co., Tokyo, Japan) with a resolution of 4 cm−1 and with 100 scans. Origin (Origin 8.5, OriginLab Co., Northampton, MA, USA) and LabSpec (LabSpec Version 5.58.25 Horiba/Jobin-Yvon, Kyoto, Japan) software were used for spectral analysis and pre-processing of raw data.
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.
