TechConnect Global Innovation Awards at the TechConnect World Innovation Conference & Expo (TCWI) 2018

The University of Hong Kong (HKU) has won two TechConnect Global Innovation Awards at the TechConnect World Innovation Conference & Expo (TCWI) 2018 to be held in the United States in May.

The two award winning innovations are “Omniphobic porous membrane and methods for preparing the same” and “Super Steel – A method for the fabrication of a super-strong and ductile multi-phase steel”, both by the HKU Department of Mechanical Engineering.

Super Steel – A method for the fabrication of a super-strong and ductile multi-phase steel

This Super Steel developed by Dr HUANG Mingxin (left) and Dr HE Binbin (right) at the Department of Mechanical Engineering achieves an unprecedented yield strength of 2.2 GPa and uniform elongation of 16%. It can be produced using conventional industrial processing routes, including warm rolling, cold rolling and annealing. Raw materials cost is only 20% of the maraging steel used in aerospace and defence applications.

Omniphobic porous membrane and methods for preparing the same

Professor WANG Liqiu (right) and Mr ZHU Ping An (left) at the Department of Mechanical Engineering developed this innovative microfluidic-droplet-based technique, for the fabrication of porous surfaces which is very much similar to shaped-cookies made by baking molds. The molds are uniform micron-sized droplets that are produced by microfluidics technology with precise control over their size, structure, and composition. Molded by microfluidic droplets, commercial-scale uniform microstructures are produced at low cost. The breakthrough will change the way liquid-repellent surfaces are fabricated for robust liquid-repellency, strong mechanical stability, and economical production at a commercial scale. It also paves the way for further progress in creating surface structures by design, and in tailoring their morphology, repellency and mechanical stability to suit a desired application in various fields.
