2024年2月28日 · Although X-ray photoelectron spectroscopy (XPS) is a surface science technique, it is widely used for chemical analysis of hydroxyapatite (HAP) minerals. The use of biomimetic mineralization strategies further complicates the chemical context with possible adsorption of biomolecules.

尽管 x 射线光电子能谱 (xps) 是一种表面科学技术，但它广泛用于羟基磷灰石 (hap) 矿物的化学分析。 仿生矿化策略的使用使化学环境进一步复杂化，可能会吸附生物分子。

O 1s XPS spectrum (Fig. 5 (e)) can be deconvoluted into three distinct peaks due to OH, P-O and P-O-P, and they have a binding energy of 530, 531.5 and 533.7 eV, respectively. The XPS...

2022年7月21日 · The XPS technique was used to analyze the chemical states and surface composition of the pure 1D HAP and 0.7% Cu/HAP nanocomposites, and the resulting spectra are depicted in Figure 3. The full survey showed the presence of calcium (Ca 2p), phosphorous (P 2p), oxygen (O 1s), and carbon (C 1s) in both the samples ( Figure 3 a).

The O 1s XPS spectrum (Figure 3 d) has three distinct signals at 531.1, 532.5, and 533.2 eV for the pure 1D HAP, which belonged to the Ca−O bond, P−O bond, 43 and O−H fingerprint of...

Nd:YAG (532 nm) pulsed laser deposition (PLD) has been used to produce crystalline hydroxyapatite (HAP) coatings at room temperature onto silicon substrates. The PLD HAP coatings were...

2002年9月1日 · X-ray photoelectron spectroscopy (XPS) was measured for the dry body of hydroxyapatite (HAP)–collagen (COL) nanocomposites cross-linked using glutaraldehyde (GA). Survey scan XPS showed the elemental spectra of N, C, …

我们报告了在选择性掺杂 Fe 3+离子的羟基磷灰石 (HAp) 纳米带中形成钙空位 (V Ca ) 和氢氧离子空位 (V OH )的阴极发光 (CL) 和 X 射线光电子能谱 (XPS) 研究。HAp 晶格的 Ca(II) 离子。此外，我们报告了掺杂 Fe 浓度低于 1 原子百分比 (at.%) 的纳米带的顺磁性行为，除了即使在 12 at.%

测量了使用戊二醛（GA）交联的羟基磷灰石（HAP）-胶原（COL）纳米复合材料的干燥体的X射线光电子能谱（XPS）。 XPS测量扫描显示N，C，O，Ca和P的元素光谱，它们来自HAP和COL。 XPS证实了HAP的Ca2 +与COL分子的RCOO-之间的共价键形成。 可以从C1和N1谱带评估COL纤维之间的桥形成。 干燥期间溶胀水的脱水导致COL原纤维之间悬垂GA的连接距离缩短，并有助于进一步的交联反应。 交联引起COL长度尺度单位的扩大。 在交联的HAP-COL纳米复合 …

2022年3月15日 · The prepared HAP/ZIF-67 was characterized by XRD, SEM, TEM, BET, FT-IR and XPS techniques, and was applied to eliminate uranium(VI) from aqueous solutions under various conditions, i.e., pH, coexisting ions, temperature and contact time.
