Unexpectedly, the t-Ni-supported Pd NPs, which seemed to have a surface Ca impurity, appeared to be more active than the Ca-free (p-Ni) system. The method that was developed allows a uniform nanoparticle size distribution (4,4☐.8 nm) to be obtained. nano-spherical SiO 2, to the target carrier technical grade Ni (t-Ni) or high purity Ni (p-Ni) grains. Video: High performance multi-technique XPS System for semiconductor device analysisIn this paper we report a new nanometallic, self-activating catalyst, namely, Ni-supported Pd nanoparticles (Pd NPs/Ni) for low temperature ammonia cracking, which was prepared using a novel approach involving the transfer of nanoparticles from the intermediate carrier, i.e. Video: Analyzing surface chemistry of the battery and energy storage materials with XPS techniques X-ray photoelectron spectroscopy is a powerful technique for the chemical analysis of the surface of materials. 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.
