Optical manipulation of work function contrasts on metal thin films

A/Prof Tan Swee Ching and his team have successfully developed a new method of optically manipulating metal work function. Work function of a material is typically known to be independent of light intensity based on our present understanding. However, the team has discovered a special case where there is a ‘light-intensity dependent’ change in work function in metal thin films. This work has been published in Science Advances.

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
