2018年1月1日 · To analyze the process of fiber ingestion into cells and the cells-fibers interactions, a spin-probe electron paramagnetic resonance (EPR) analysis was performed supported by transmission electron microscopy (TEM) and cell viability measurements as a function of the incubation time.

2024年11月8日 · 电子顺磁共振（EPR）光谱学是一项直接且先进的技术，专门用于检测和表征纳米材料中的氧空位。 该技术能够提供材料表面及内部未配对电子的独特“指纹”信息，成为识别单电子捕获现象的一种高度灵敏方法。 EPR光谱的应用范围广泛，不受样品形态（液体或固体）的限制，均能提供有价值的信息。 EPR光谱的基本原理在于，顺磁样品（即含有未配对电子的样品）在特定磁场条件下能够吸收电磁辐射。 这一现象的发生遵循特定的频率，由公式hv=gbβ决定，其 …

2002年11月1日 · The EPR and 13 C NMR studies on detonation carbon and ultradisperse diamond clusters, together with available X-ray diffraction and TEM data, have shown that a high concentration of paramagnetic centers (up to 10 20 spin/g) is due to structural defects (dangling C–C bonds) on the diamond cluster core. It is found that the defects are ...
