在该项目的第一阶段，Kiani博士的团队与Kennedy实验室合作，开发了有效且廉价的纳米纤维硅（NfSi）制造方法，其混合纳米结构表面由纳米纤维或纳米颗粒组成，在某些情况下，两者结合。此外，肯尼迪实验室及其营销合作伙伴DigiKey公司成功地将这种结构商业化。Kennedy实验室和Kiani博士的团队在与目前的合作伙伴接洽后，旨在探索将NfSi用于红外（IR）发射器的可能性。考虑到现有的一系列实验知识和制造的NfSi的有希望的初始发射率结果，在该项目的第二阶段，将开发一种制造基于NfSi的红外发射器的新方法。与当前的纳米和微制造工艺相比，采用激光方法将显著降低制造的复杂性。此外，使用硅片制造红外发射器将使其易于小型化，而不需要钨丝，从而使制造过程更简单，更顺畅。这种由Kiani博士的团队开发的内部开发的NfSi结构将为肯尼迪实验室提供独特的优势，使其具有引入新颖性，降低成本，在邻近竞争市场中成长和繁荣的知识。此外，这一成就将确立uit在激光纳米加工技术领域的领先地位，吸引潜在投资者和合作者的关注。总的来说，拟议的研究将使清洁和绿色的微纳米制造以及在安大略省和加拿大制造有效的小型化红外发射器成为可能。此外，通过该研究项目开发的技术可用于生产商用质量的传感器和探测器，用于物联网应用，包括健康监测和数据中心与光学设备的互连。

In the first phase of this project, Dr. Kiani's team, in collaboration with Kennedy Labs, developed effective and inexpensive methods for nanofibrous silicon (NfSi) fabrication with hybrid nano structured surface consisting of nanofibers or nano particles and in some cases, a combination of both. In addition, commercialization of such structures was successfully done by Kennedy Labs along with their marketing partner, DigiKey Corporation. Upon being approached by current collaborator, Kennedy Labs and Dr. Kiani's teams have aimed to explore possibilities to use NfSi for Infra-Red (IR) emitters. Considering available knowledge with series of experiments and promising initial emissivity results of the fabricated NfSi, in the second phased of this project, a novel method for fabrication of NfSi-based IR emitters, will be developed.When compared to contemporary nano and micro fabrication processes, employing a laser approach will decrease the complexity of fabrication significantly. Furthermore, fabrication of IR emitters using silicon wafer would enable easy miniaturization with no requirement of tungsten wires resulting in a less complicated and smoother fabrication process. Such in-house developed NfSi structure developed by Dr. Kiani's team, will provide unique advantage to Kennedy Labs of having knowledge to introduce novelty, reduce cost, grow and thrive in adjacent competitive market. Also, such achievement will establish UOIT as a leader in nano processing technology using laser, attracting attention from potential investors and collaborators. Overall, the proposed research will enable clean and green micro and nano manufacturing along with fabrication of effective and miniaturized IR emitters in Ontario and Canada. In addition, the technology developed through this research project can be used for production of commercial quality sensors & detectors for IoT applications including health monitoring and in data-center interconnect with optical devices.
