Two COCHE Co-PIs have been bestowed as the winners of the Falling Walls Science Breakthroughs 2023

Updated: Sep 25

We are thrilled to announce and celebrate the outstanding achievements of our COCHE Co-PIs, Prof. Shih-Chi Chen and Prof. Zuankai Wang, who are selected as winners for the Falling Walls Science Breakthroughs of the Year 2023 in the category of Engineering and Technology.

Falling Walls Foundation launched its Global Call for the Falling Walls Science Breakthroughs of the Year 2023, inviting leading actors in science and academia worldwide to nominate the most exceptional breakthroughs and science projects across multiple categories. One of the categories in focus is Engineering & Technology.

Under the chairmanship of Prof. Metin Sitti, the jury for Engineering & Technology is set to identify and recognize 10 outstanding winners from a pool of exceptional nominees. Among these remarkable winners, two of them are COCHE Co-PIs:

Prof. Shih-Chi Chen, from the Chinese University of Hong Kong, has been recognized for “Breaking the Wall to Using Ultrafast Multi-Material 3D Nanofabrication”.

Prof. Chen has created a pioneering nanoscale 3D printing system utilizing femtosecond projection. with a resolution of 20 nm, delivering an impressive printing rate of 400mm3 per hour. This platform also has significantly reduced costs, reaching an economical rate of US$1.5 per mm3, enabling nanofabrication with a wide range of 20 different materials. The breakthrough tackles critical fabrication obstacles encountered in the fields of nanotechnology, photonics, energy, and biotechnology.

Prof. Zuankai Wang, from the Hong Kong Polytechnic University, has the innovation on structured thermal amour (STA), recognized with the accolade of “Breaking the Wall to the Leidenfrost Effect.”

Prof. Wang's groundbreaking STA strategy revolutionizes liquid cooling at extreme temperatures, breaking the Leidenfrost effect at high temperatures. This innovation has significant implications for various fields, including aero-engines, space-engines, next-generation nuclear reactors, and electronics cooling. By pushing the boundaries of liquid cooling beyond 1,000°C, this breakthrough enables remarkable advancements in thermal cooling for nuclear power plants, engines, microelectronic chips, and electronic devices. Additionally, Prof. WANG's discovery extends the temperature range of super wettability, a top emerging technology recognized by the International Union of Pure and Applied Chemistry (IUPAC) in 2021, unlocking limitless applications in chemistry and other domains.

We extend our heartfelt congratulations to Prof. Shih-Chi Chen and Prof. Zuankai Wang for their being recognized of their groundbreaking contributions. We also anticipate the continued progress and achievements of COCHE in driving innovation and advancement in the field of engineering and technology.
