To have an additional control on the procedure, the experiment was repeated on a thick GO film deposited on a Au substrate.
The obtained C/O ratios confirm the occurred GO reduction. X-ray photoelectron spectroscopy is a powerful technique for the chemical analysis of the surface of materials. The collected XPS survey spectra, together with their peak area percentages and C/O ratios, are reported in figures S1S8. This webinar covers the basics of X-ray photoelectron spectroscopy, with a special emphasis on how it can be used in the field of polymer surface analysis. We present how a dual mode ion source can be used for multi-technique sample analysis, showing the importance of sample cleaning and how depth profiles can be performed. Multi-technique Surface Analysis and Cluster Ion Sample Cleaning XPS delivers chemical state information from the topmost nanometers of a sample surface, enabling you to measure passivation coatings, understand catalyst chemistries, and develop bio-compatibility coatings.
This webinar is designed to offer training to current users of Avantage software and act as an introduction to those unfamiliar with it.Įxplore a number of applications for thin film coating analysis including forensic studies, graphene, multi-layered glass, coated fabrics and photovoltaics. Understanding Surface Chemistry with Avantage Software Understanding XPS images and depth profiles with Avantage Software - Part 2īy watching the webinar, you will learn how to use the right tools to understand multi-level data sets, such as depth profiles and images.
