Biography：
Dr. Long studied at Cambridge University, United Kingdom and currently hold senior lecturer position in Nanyang Technological University, Singapore. Her research area is to develop different nanostructured functional thin films. She has successfully implemented two technology transfer from lab to industry for hard disk company and car grooming company. She has secured up to S$ 2 million research fundings to support her recent focus in developing energy saving coatings including one of the most competitive funding National Research Foundation Proof of Concept. (NRF POC). She has overall citation >700 with H-index of 16 by google scholar. She is also the pioneer in online learning in NTU.

Abstract：
Thermochromic material responds to solar spectrum differently at the stimulus of heat which makes it attractive in the energy saving smart windows application. The most studied inorganic VO2 has the intrinsic problems of low luminous transmission (Tlum) and low solar modulation (ΔTsol the transmission difference between high and low temperatures). Numerous efforts such as employing dopings, nanoparticle-based composites, and nano-porous structuring have been widely studied. Our group have developed five new approaches to tackle this veritable challenge, namely, biomimetic nanostructuring including moth eye, photonic structure, grided structures tunable plasmonic structures and organic and hybrid structures. In addition, an active control has also been applied to thermochromic material to generate a new electro-thermochromics materials.
