2017年4月19日 · The present paper describes the implementation of XPS analysis, using traditional, commercially available XPS equipment, to shed light on the surface composition and binding interactions of spontaneously coassembled nanocomplexes composed of …

2023年7月3日 · X-ray photoelectron spectroscopy (XPS) is widely used to determine the chemical and electronic states of atoms within a material. However, it is often complex to interpret the O 1s region in metal oxides, where an ∼531 eV binding energy feature appears between lattice oxygen (∼530 eV) and oxygen-containing surface species (∼532 eV).

2024年12月23日 · By tracking the evolution of the catalyst surface during catalyst preparation, AP-XPS can assist in identifying the parameters for preparing an expected catalyst structure. Additionally, it can uncover adsorbate coverage-induced surface restructuring by monitoring the photoemission features of key elements as the gas pressure increases.

2017年5月7日 · 这里，我们将在UHV下干燥过夜的吸湿性样品后，通过X射线光电子能谱（XPS）确定表面成分和化学键的详细实验方案。 我们用这种方法研究了二元钙的表面化学沉积在晶圆上的透明质酸硫酸盐（HAS）-Ca 2+ -siRNA的2+ -siRNA纳米复合物和三元纳米复合物。 值得注意的是，我们证明了该协议可用于研究传统XPS仪器的表面组成和沉积的纳米复合物的相互作用，并且只需要相对少量的纳米复合物悬浮液即可。

2023年9月21日 · Here we demonstrate the first use of cryo-XPS for the measurement of two PEG-functionalized nanomedicines: a polymeric drug delivery system and a lipid nanoparticle mRNA carrier. The observed differences between cryo-XPS and standard XPS measurements indicate the potential of cryo-XPS for providing quantitative measurements of such nanoparticle ...

2021年1月14日 · Taking 50 years of effort, ambient pressure X-ray photoelectron spectroscopy (APXPS) has become a useful characterization tool for studies in heterogeneous catalysis and electrocatalysis.

单反涉及到金属的 纳米材料 ，均可能需要 xps分析 ，对于外行专业（非材料）来说，xps分析非常困难，今天我作为非材料专业人，来剖析xps分析步骤，希望对大家有用。 题外话：曾经找机构帮分析，那个天价堪比直接抢钱，自己会才是真的本事。 一、何时需要分峰？

2019年4月22日 · X-ray photoemission spectroscopy (XPS) depth profiling using monatomic Ar + ion etching sources is a common technique that allows for the probing of the vertical compositional profiles of a wide range of materials. In polymer-based organic photovoltaic devices, it is commonly used to study compositional variations across the interfaces of the ...

引言x射线光电子能谱（xps）是一种研究物质表层元素组成与离子状态的表面分析技术。 它的基本原理是用单色射线照射样品，使样品中原子或分子的电子受激发射，然后测量这些电子的能量分布。

2024年4月29日 · We demonstrate that ambient pressure X-ray photoelectron spectroscopy (APXPS) can be used for in situ studies of dynamic changes in surface chemistry in a plasma environment.
