ABSTRACT

This manuscript outlines current research activities based on ion beam science at GNS Science in New Zealand. Ion beam analysis methods include Rutherford backscattering and nuclear reaction analysis which trace back to Rutherford's famous ‘gold foil’ and ‘splitting the atom’ experiments. These ion beam-based methods generally offer the ability to analyse materials for every element of the periodic table, to ppm concentrations, and with depth profiles ranging from a few nm to several microns. Ion beam methods are now also used to modify and create new materials precisely. Rutherford’s early research now has a legacy at GNS Science’s Materials team to discover, design, and develop materials for energy efficient modern applications for a low carbon future. These include magnetic sensors for security products, nanostructured magnetic materials for energy conversion, thermoelectric devices for energy harvesting, and catalytic development for clean energy carriers and energy efficient communication devices.

摘要

这份手稿概述了新西兰 GNS Science 基于离子束科学的当前研究活动。离子束分析方法包括卢瑟福背向散射和核反应分析，这可以追溯到卢瑟福著名的“金箔”和“原子分裂”实验。这些基于离子束的方法通常能够分析元素周期表中每个元素的材料，浓度达到 ppm，深度分布范围从几纳米到几微米不等。离子束方法现在也用于精确修改和创建新材料。Rutherford 的早期研究现在在 GNS Science 的材料团队中留下了遗产，致力于为低碳未来的节能现代应用发现、设计和开发材料。这些包括用于安全产品的磁传感器，
