Using micro-fibrous red phosphorus to produce clean fuel (hydrogen) from water with high efficiency

Innovative Breakthroughs: Red phosphorous is abundant in the earth’s crust and can be extracted fairly easily. The process of conversion leaves only water as a by-product, without any toxic gas.

Academic merits: Published in the international journal "Angewandte Chemie”.

Plasmonic and Upconversion Nanomaterials 

Innovative Breakthroughs: Invented an innovative lanthanide-sensitized oxide for capturing infrared light for solar harvesting by solar cells, reaching a maximal efficiency of 16%, which is at least double the efficiency of traditional nano-upconversion materials.

Academic merits: Published in "Nature Communications" under the Nature publishing group.

Development of Thermoelectric Generators (TEGs)

Innovative Breakthroughs: The team developed thermoelectric generators (TEGs) that achieved a power density as high as 9.2 mW cm-2 at a temperature difference of 52.5 K, which is the highest value reported so far for the electroplated micro-TEGs in the literature.

Academic merits: Published in the international journal Journal of Microelectromechanical Systems
