Continuously tune the work function of conductors in a wide range for the first time.

Continuously tune the work function of conductors in a wide range for the first time. Ouyang Jianyong and his team developed a novel method to continuously tune the work function of ITO, Ag, Au, PEDOT:PSS and rGO in a wide range by using controlling the ratio of Cu2+ to poly(amido amine) (generation 3) (PAMAM). The mechanism for the work function change is ascribed to the effect of Cu2+ on the interfacial dipole moment between substrates and Cu2+-PAMAM. They also demonstrated its application in high-performance polymer solar cells. This work has been published in Advanced Functional Materials.

Solar Energy Triggered Clean Water Harvesting from Humid Air Existing above Sea Surface Enabled by a Hydrogel with Ultrahigh Hygroscopicity

A/Prof Tan Swee Ching and his team have successfully developed a novel solar energy triggered, low-energy method to pull clean water from humid air that exists above sea surface. A super-hygroscopic hydrogel, capable of absorbing more than 4X its own weight with water was employed for the process. The team had constructed a floating prototype
