The morphology of the prepared nHAp was studied using a high-resolution transmission electron microscope (HRTEM; Philips CM 120 model) operating at 120 kV. Small amounts of nHAp were scattered in 10 mL ethanol and sonicated at 10 Kv for 10 min before HRTEM observation. A cryo-microtomed samples were subsequently formed with a Leica microtome (South Africa), positioned on 100 mm by 100 mm carbon copper grids.

Fourier Transform Infrared Spectroscopy analysis. The infrared spectra were measured using a Perkin Elmer Universal ATR spectrometer to identify the functional group constituents of EB-TiO 2 . A very small amount of sample was placed in the sample holder. An initial background check was performed before scanning in the range of 400-4500 cm -1 .
X-Ray Diffraction analysis. The crystallinity of the modified Eb-TiO 2 was assessed using X-Ray Diffraction (XRD). The XRD diffractometer (PANalytical-Empyrean instrument; Co radiation 1.54056 A o ) was calibrated with a voltage of 40 kV, current of 40 mA, and time of 1 s and analyzed between 0° and 90 o (2 theta).
Transmission Electron Microscopy analysis. Transmission Electron Microscopy (TEM) was used to observe the particle size, shape, and distribution of EB-TiO 2 .

A transmission electron microscope (TEM) was used to observe the particle size, shape, and distribution of EnHAp. Very small quantities of the EnHAp powder were dispersed in 10ml ethanol and sonicated at 10 kV for 10 min. Subsequently, thin cross-sections of cryo-microtomed specimens were prepared using a Leica microtome (South Africa) and placed on carbon copper grids. The analysis was conducted using a TEM (Philips CM 120 model) operating at 120 kV. pH test 1.5 g of each sample (Table 1) were placed in a beaker containing 50 mL deionized water. The solution was constantly agitated at a low speed of 600 r/min and the pH measured at 1 min intervals for a duration of 10 min. A pH meter (Starter 300, Ohaus Incorporation, USA) equipped with a temperature sensor was used to record changes in the pH reading. Similarly, the samples were exposed to 2 mol L -1 hydrochloric acid (HCl) and the pH recorded after 10 min.
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.
