项目摘要
Phosphorus, one of the major three nutrients for plants, is required for plant growth, and it serves as an indicator for global environmental sustainability. It is important to understand the variations of phosphate in soils and soil-water systems in order to address a number of global challenges such as food production and regulating fertilizer applications for crops grown in various soil conditions and climate regimes. The goal of this research project is to use the latest graphene-based technology to develop a low-cost sensor capable of real-time monitoring of the phosphorus content in soil. This collaborative project between researchers at the U.S. institutions of Kansas State University and the University of Alabama at Huntsville, and the U.K. institution of the University of Sheffield, will be conducted by an interdisciplinary team with expertise in soil and water science, geology, electrical engineering, and the fundamental chemistry and physics of soil-graphene interactions. Development of such sensors will enable farmers to choose the right amount of fertilizer to apply to the fields.This research project aims to develop an additively-manufactured graphene sensor array and a portable wireless system for continuous in-field monitoring of electrochemical signals. Such a system would be applied to the mapping of soil phosphates in diverse agricultural landscapes in the US Midwest (Kansas) and the UK East Midlands (Derbyshire Dales and Peak District). Structurally and chemically tailored graphene materials will be used to print graphene sensors with quasi-three-dimensional and porous graphene morphologies. The materials will be designed to achieve high electrical conductivity as well as reversible and high electron charge-transfer characteristics when exposed to soil phosphates. A fundamental understanding of phosphate ion binding with various graphene morphologies will be gained using state-of-the-art ultrafast laser spectroscopy and high-end computational modeling. A Bluetooth communication module with an Arduino platform will be constructed and interfaced with the sensor arrays for sensor data acquisition. Controlled environmental testing of spatial and temporal variations of phosphate ions over other interfering ions will be carried out at specific sites in Kansas and at Europe's largest controlled environment P3-facility housed at the University of Sheffield. The fundamental sensing characteristics and drift optimization with temperature, humidity, salinity, and soil pH will be identified and optimized for reliable data collection. Soils ranging from coarse calcareous to loamy montmorillonitic and silicate-rich soils in two countries will be utilized as testbeds to measure the sensing capabilities of the printed arrays. Furthermore, the project will explore the detection of phosphates over other interfering ions in soils, such as nitrates, silicates, and heavy metals, by using chemically-functionalized graphene sensors. This research will help to strengthen the national and economic security of both the U.S. and the U.K. and will strengthen the future workforce by bridging the gaps between science, technology, agriculture, and environmental disciplines through the training of graduate students, undergraduate students, and postdoctoral scientists.
磷是植物的三大营养元素之一,是植物生长所必需的,也是全球环境可持续性的指标。了解土壤和土壤-水系统中磷酸盐的变化对于解决一些全球性挑战非常重要,例如粮食生产和调节在各种土壤条件和气候制度下生长的作物的肥料施用。该研究项目的目标是利用最新的石墨烯技术开发一种低成本的传感器,能够实时监测土壤中的磷含量。这个合作项目是由美国堪萨斯州立大学和位于亨茨维尔的亚拉巴马大学的研究人员以及英国该研究由谢菲尔德大学的一个研究机构进行,将由一个跨学科的团队进行,该团队具有土壤和水科学,地质学,电气工程以及土壤-石墨烯相互作用的基础化学和物理学方面的专业知识。该研究项目旨在开发一种增材制造的石墨烯传感器阵列和一种便携式无线系统,用于连续现场监测电化学信号。这样一个系统将被应用到不同的农业景观在美国中西部(堪萨斯)和英国东米德兰兹(德比郡山谷和峰区)的土壤磷酸盐的映射。结构和化学定制的石墨烯材料将用于打印具有准三维和多孔石墨烯形态的石墨烯传感器。这些材料将被设计为在暴露于土壤磷酸盐时实现高导电性以及可逆和高电子电荷转移特性。利用最先进的超快激光光谱学和高端计算建模,将对磷酸根离子与各种石墨烯形态的结合有一个基本的了解。将构建带有Arduino平台的蓝牙通信模块,并与传感器阵列接口,用于传感器数据采集。将在堪萨斯的特定地点和位于谢菲尔德大学的欧洲最大的受控环境P3设施进行磷酸盐离子相对于其他干扰离子的空间和时间变化的受控环境试验。将识别和优化基本传感特性和温度、湿度、盐度和土壤pH值的漂移优化,以进行可靠的数据收集。两个国家的土壤从粗石灰质到肥沃的蒙脱石和富含硅酸盐的土壤将被用作测试台,以测量印刷阵列的传感能力。此外,该项目将探索通过使用化学功能化石墨烯传感器检测土壤中的磷酸盐,而不是其他干扰离子,如硝酸盐,硅酸盐和重金属。这项研究将有助于加强美国和英国的国家和经济安全。并将通过培养研究生、本科生和博士后科学家,弥合科学、技术、农业和环境学科之间的差距,加强未来的劳动力队伍。
