"Gas sensors play a key role in monitoring urban pollution, indoor air quality and industrial processes. Semiconducting metal oxides (MOx) have dominated the chemiresistive commercial gas sensing market for decades but have drawbacks in response time and power consumption. This project will investigate a new generation of 2-dimenstional (2D) materials beyond graphene. Strong electron interaction and large surface area of these novel semiconducting 2D materials make them highly sensitive to chemical changes and therefore, very attractive for new generation of electrochemical and chemiresistive gas sensing. The aim of this project is to address the limitations of traditional MOx sensors by nano-engineering these 2D materials for a thin-film sensor platform with superior sensing ability. By adopting scalable nanomanufacturing strategies, the project targets the development of low cost, high performance gas sensors that could be exploited for consumer grade indoor air quality monitoring. This will require nanomaterials synthesis, processing, characterization, various deposition technologies, device fabrication and integration towards detection of specific gases."

“气体传感器在监测城市污染、室内空气质量和工业过程中发挥着关键作用。半导体金属氧化物（MOx）几十年来一直主导着化学电阻式商用气体传感市场，但在响应时间和功耗方面存在缺陷。该项目将研究石墨烯之外的新一代二维（2D）材料。这些新型半导体二维材料的强电子相互作用和大表面积使它们对化学变化高度敏感，因此对于新一代电化学和化学电阻气体传感非常有吸引力。该项目的目的是解决传统MOx传感器的局限性，通过纳米工程这些二维材料的薄膜传感器平台具有上级传感能力。通过采用可扩展的纳米制造策略，该项目的目标是开发低成本，高性能的气体传感器，可用于消费级室内空气质量监测。这将需要纳米材料的合成、加工、表征、各种沉积技术、设备制造和集成，以检测特定气体。"
