Oxidation State Analysis

The oxidation state of nanoparticles is a critical aspect of their chemical and physical properties, influencing reactions, stability, and functionality in various applications from catalysis to biomedical uses. Understanding the oxidation state allows researchers to optimize nanoparticle design, predict behavior in different environments, and harness their properties for specific applications. Accurate analysis of oxidation states is therefore essential for advancing nanotechnology, facilitating innovation in materials science, and improving the performance of nanoparticles in industrial and medical contexts.

Nanoparticles Oxidation State Analysis Techniques

STEMart’s oxidation state analysis services provide a comprehensive suite of methodologies to ascertain the oxidation states of nanoparticles with high precision and reliability.

• X-ray Absorption Spectroscopy (XAS)

XAS exploits the absorption of X-ray photons to probe the local environment around specific atoms, providing valuable information about their oxidation states, coordination numbers, and molecular geometries.

• Electron Energy Loss Spectroscopy (EELS)

EELS analyzes the energy loss of electrons scattered by the sample to determine elemental composition and oxidation states.

• X-ray Photoelectron Spectroscopy (XPS)

XPS employs photoelectron emission following X-ray irradiation to provide information about the elemental composition and chemical state.

• Mössbauer Spectroscopy

Mössbauer spectroscopy exploits the resonance fluorescence of gamma rays to assess the oxidation state in iron-containing nanoparticles.

STEMART provides comprehensive oxidation state analysis for a wide range of nanoparticle samples, including but not limited to metallic nanoparticles, transition metal nanoparticles, quantum dots, functionalized nanoparticles, semiconductor nanocomposites, composite nanoparticles
