Global energy demand is growing rapidly and significantly as energy, the key ingredient in all sectors of modern economy, has invaded the quality of life today due to our dependency on its abundant and uninterrupted supply. In particular, the increased levels of the green house gas, carbon dioxide (CO2), in the atmosphere is believed to be a major contributor to global warming and pollution due to the burning of fossil fuels used in various spheres of our life. A significant amount of heat energy is wasted by aluminum and steel industries. The recovery of these large amounts of wasted thermal energy will provide opportunity for improving overall energy efficiency in these energy-intensive industrial processes. Thermoelectric (TE) materials, which can generate electricity by recycling the heat wasted from industries using high temperature processes, could play an important role in global sustainable energy solution. Therefore, the long term vision of this project is to conduct fundamental and applied research on thermoelectric properties of nanostructured thin films of transition metals oxides (both n and p types) to find suitable nanomaterials for the conversion of electrical energy from heat wasted from industries, sun and human bodies. Sol-gel techniques will be mainly used to synthesize these transition metal oxides nanomaterials. An appropriate precursor will be chosen for the relevant oxide and appropriate salt will be used for the doping of the oxide. The newly synthesized nanomaterials will be characterized for electrical, structural and optical properties. A combination of n-type and p-type TE nanomaterials will be selected to develop a technology to generate electrical energy from industrial waste heat. The outcome of the scientific findings of this project is expected to help Canadian industries to develop economical, ecological and efficient materials in harvesting energy by recycling wasted energy.

全球能源需求正在迅速而显着增长，因为能源是现代经济所有领域的关键要素，由于我们依赖其丰富且不间断的供应，因此入侵了当今的生活质量。特别是，由于我们生活的各个领域使用的化石燃料燃烧，据信大气中的温室气体，二氧化碳（CO2）的水平增加是造成全球变暖和污染的主要因素。铝和钢铁工业浪费了大量的热能。这些大量浪费的热能的恢复将为提高这些能源密集型工业过程中的总体能源效率提供机会。热电（TE）材料可以通过使用高温过程回收从行业浪费的热量来发电，在全球可持续能源解决方案中起重要作用。因此，该项目的长期视力是对过渡金属氧化物（N和P类型）的纳米结构薄膜的热电薄膜进行基础和应用研究，以找到合适的纳米材料，以从从工业，太阳和人体中浪费的热量转化电能。溶胶 - 凝胶技术将主要用于合成这些过渡金属氧化物纳米材料。将选择适当的前体作为相关的氧化物，并将适当的盐用于氧化掺杂。新合成的纳米材料将用于电，结构和光学特性。将选择N型和P型纳米材料的组合，以开发一种从工业废热中产生电能的技术。预计该项目的科学发现的结果有望帮助加拿大行业通过回收浪费能量来开发经济，生态和有效的材料在收获能源方面。
