This project aims to unravel the ways in which hyperaccumulators work. Hyperaccumulators are plants that have the remarkable ability to concentrate up to six per cent nickel in their leaves and up to 25 per cent in their sap. These plants can be used in phytomining – a new technology to recover nickel from mining waste or contaminated land by growing and harvesting these plants and extracting nickel from their biomass. This project seeks to understand how the plants accumulate nickel by using tracers and synchrotron techniques to follow the pathways of nickel from the soil into the plants. This knowledge may help us to optimise agronomic processes affecting nickel uptake to enable successful phytomining.

该项目旨在揭示hyperplanet的工作方式。金丝桃是一种具有非凡能力的植物，其叶子中的镍含量高达6%，汁液中的镍含量高达25%。这些植物可用于植物采矿-一种新技术，通过种植和收获这些植物并从其生物质中提取镍，从采矿废物或污染土地中回收镍。该项目旨在通过使用示踪剂和同步加速器技术跟踪镍从土壤进入植物的途径来了解植物如何积累镍。这些知识可以帮助我们优化影响镍吸收的农艺过程，以实现成功的植物采矿。
