Environmental monitoring and treatment are required to protect the public and the environment from toxic contaminants and pathogens that can affect a variety of media, in particular, air and water. This research program applies several emerging technological innovations, including nanomaterial fabrication, ultraviolet light-emitting diode (UV-LED), and artificial intelligence (AI), to address the very important global issue of monitoring and treatment of air and water quality. The long-term vision of the research program is the development of miniature sensors for the worldwide monitoring of air and water quality, and the creation of point-of-use, maintenance-free air and water treatment systems. The proposed research program focuses on the development of a novel photo-activated sensing technology for air quality monitoring and a photoelectrochemical system for water treatment by the combined elimination of microbial and chemical contaminants. Gas sensing system: The advent of the wireless sensor network, a group of spatially dispersed and dedicated sensors, could ultimately result in a more comprehensive understanding of global environmental patterns and help to address a number of global climate change issues. In the proposed research, we will take a new direction in sensor development by creating semiconductor-based sensor arrays activated by UV-LED that are responsive to a variety of gas pollutant mixtures. We will then apply AI to teach the sensors to not only detect the presence of these gases, but to also identify their composition. This is a challenging but highly rewarding goal, which, when achieved, will help us to meet the demands of global-scale sensor deployment for environmental monitoring. Water treatment system: With population pressures, climate change, and overuse making every water source significant, we need to look to advanced treatment technologies. We will develop a novel photoelectrochemical system by integrating the electrochemical production of oxidative agents with UV-LED irradiation in a single integrated unit. This new technological approach can result in the simultaneous inactivation of microorganisms and decomposition of micropollutants from water, while operating at low power and without maintenance. The proposed program of research will further Canada's expertise and competitiveness in environmental sciences by providing a competitive training environment for highly-qualified personnel (HQP). HQP trained in this program will develop essential theoretical and analytical skills as well as the technological know-how to lead research and development activities related to sensing technology, AI, and environmental monitoring. The principal investigator has nearly 20 years of experience in the development of UV reactors and systems in industry and academia. He has been involved in leading research programs, developing new technologies, product innovation, and the creation of a successful company.

需要环境监测和治疗，以保护公众和环境免受可能影响各种媒体的有毒污染物和病原体，尤其是空气和水。该研究计划应用了一些新兴的技术创新，包括纳米材料制造，紫外线发光二极管（UV-LED）和人工智能（AI），以解决对空气和水质的监测和处理非常重要的问题。研究计划的长期视野是开发微型传感器，以在全球范围内监测空气和水质的监测，以及创建使用点，无维护的空气和水处理系统。拟议的研究计划着重于开发用于空气质量监测的新型光激活感应技术，以及通过消除微生物和化学污染物的合并消除水处理的光电化学系统。 燃气传感系统：无线传感器网络的出现，一组空间分散和专用的传感器，最终可能会对全球环境模式有更全面的了解，并有助于解决许多全球气候变化问题。在拟议的研究中，我们将通过创建由紫外线主动的半导体传感器阵列来朝着传感器开发方向迈出新的方向，这些传感器阵列对各种气体污染物混合物有响应。然后，我们将应用AI教传感器不仅检测这些气体的存在，还可以确定它们的组成。这是一个充满挑战但有益的目标，一旦实现，这将帮助我们满足全球规模的传感器部署对环境监测的需求。 水处理系统：随着人口压力，气候变化和过度使用，使每种水源都显着，我们需要研究先进的治疗技术。我们将通过将氧化剂的电化学生产与单个集成单元中的紫外线辐射整合在一起，从而开发一种新型的光电化学系统。这种新的技术方法可能会导致微生物同时失活，并在低功率和不维护的情况下从水中从水中分解微量污染物。 拟议的研究计划将通过为高度合格的人员（HQP）提供竞争性的培训环境，进一步进一步加拿大在环境科学方面的专业知识和竞争力。在该计划中接受培训的HQP将开发基本的理论和分析技能，以及领导与传感技术，AI和环境监测有关的研究和开发活动的技术知识。首席研究人员在工业和学术界的紫外反应堆和系统的开发方面拥有近20年的经验。他参与了领先的研究计划，开发新技术，产品创新以及成功公司的创建。
