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.

需要进行环境监测和处理，以保护公众和环境免受有毒污染物和病原体的影响，这些污染物和病原体可能影响各种介质，特别是空气和水。该研究计划应用了几项新兴技术创新，包括纳米材料制造，紫外线发光二极管（UV-LED）和人工智能（AI），以解决监测和处理空气和水质量的非常重要的全球问题。该研究计划的长期愿景是开发用于全球空气和水质监测的微型传感器，并创建使用点，免维护的空气和水处理系统。拟议的研究计划的重点是开发一种新型的光活化传感技术，用于空气质量监测和光电化学系统的水处理，通过联合消除微生物和化学污染物。 气体传感系统：无线传感器网络是一组在空间上分散的专用传感器，它的出现可能最终导致对全球环境模式的更全面的了解，并有助于解决一些全球气候变化问题。在拟议的研究中，我们将采取一个新的方向，通过创建由UV-LED激活的传感器阵列，对各种气体污染物混合物做出响应，来开发传感器。然后，我们将应用人工智能来教传感器不仅检测这些气体的存在，而且还识别它们的成分。这是一个具有挑战性但非常有价值的目标，一旦实现，将有助于我们满足全球范围内环境监测传感器部署的需求。 水处理系统：随着人口压力、气候变化和过度使用使每一个水源都变得重要，我们需要寻求先进的处理技术。我们将开发一种新型的光电化学系统，通过将氧化剂的电化学生产与UV-LED照射集成在一个集成单元中。这种新的技术方法可以同时灭活微生物和分解水中的微污染物，同时以低功率运行，无需维护。 拟议的研究计划将通过为高素质人员（HQP）提供有竞争力的培训环境，进一步提高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将发展基本的理论和分析技能以及技术知识，以领导与传感技术，人工智能和环境监测相关的研发活动。首席研究员在工业和学术界开发紫外线反应器和系统方面拥有近20年的经验。他参与了领先的研究计划，开发新技术，产品创新和创建一个成功的公司。
