Abstract:

Efficient energy use, sometimes simply referred to as energy-saving, involves efforts to reduce the amount of energy wasted. To minimize heat loss and improve energy utilization, materials with ultra-low thermal conductivities are becoming increasingly important under the growing demand for high performance heat management and thermal insulation. Superinsulation materials based on silica aerogel offer considerably lower thermal conductivities than that of air at ambient temperature, which offer great potential in building science. Thermal barrier coatings (TBCs) based on yittria stabilized zirconia are widely used in advanced aerospace applications as high temperature thermal insulation materials.
In this seminar, I will be presenting my research activities on understanding the interfacial stability and factors controlling thermal, micro-mechanical and physical properties of these materials.
