Knowledge of the adsorption mechanism of biological molecules on hydroxyapatite (HAP) is essential to the application of HAP chromatography and to the development of HAP-based biomedical...

2015年12月1日 · Crystal structure and morphology of the nHAP were confirmed by X-ray diffraction (XRD) and transmission electron microscopy (TEM). Chemical nature of the nHAP was analyzed by Fourier transform infrared spectroscopy (FTIR) and inductively coupled plasma atomic emission spectrometry (ICP-AES).

2018年2月8日 · Here we report the development of liquid-crystalline (LC) hydroxyapatite (HAp), which is an environmentally friendly and biocompatible biomineral. Its alignment behavior, magneto-optical...

2019年12月1日 · The goal of this work was to use Ag nanoparticles during the synthesis of hydroxyapatite (Hap) to modify its characteristics, and as a result, modify the TL intensity signal when the Hap:AgNps system is exposed to gamma radiation.

2018年9月1日 · The structural properties of Ce/HAp samples were characterized by various techniques including X-ray absorption near edge spectroscopy (XANES), X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM) and energy dispersive X-ray spectroscopy (EDX).

In this investigation, hydroxyapatite (HAp) nanostructure with uniform morphologies, controllable size, nano-dispersion and narrow-size distribution in diameter has been synthesized successfully...

The TEM images illustrate the distribution of nanoparticles with a nonuniform morphology for pure HAp ( Figure 2 a).

2019年4月26日 · The nonstoichiometric HAp which contains CaHPO 4 in ionic form could react with HAp at elevated temperature and form α-calcium phosphate (JCPDS C29-0359) and whitlockite (JCPDS 09-0169) with loss of a water molecule [39].

2022年7月21日 · Hydroxyapatite (HAP) (Ca 10 (PO 4) 6 (OH) 2) has emerged as a novel catalytic support owing to its exciting features such as low solubility in water, high thermal stability, high ion-exchange ability, (16) great adsorption capacity, (17) tunable specific surface area and porosity, and adjustable acidity and alkalinity.

Crystalline hydroxyapatite (HAP) nanoparticles and nanorods have been successfully synthesized via a simple precipitation method. To control the shape and particle size of HAP nanocrystals, coordination ligands derived from 2-hydroxy-1-naphthaldehyde were first prepared, characterized by Fourier tra …
