Researchers from City University of Hong Kong (CityU) received 12 awards, including a Gold Medal with Congratulations of the Jury, five Gold Medals, three Silver Medals and three Bronze Medals at the Inventions Geneva Evaluation Days (IGED) 2021, a virtual edition of the International Exhibition of Inventions of Geneva.
“An Energy-Free, Low-Cost and High Cooling Performance Passive Radiative Cooling Technology for Building Applications” led by Dr Edwin Tso Chi-yan, Assistant Professor in the School of Energy and Environment, received the Gold Medal with Congratulations of the Jury.
To provide a sustainable and energy-saving solution to the consumption of electricity in buildings, Dr Tso has developed a passive radiative cooling paint, using the universe as a cooling source.
Unlike traditional air-conditioning systems, the passive radiative cooling paint is an energy-free and refrigerant-free cooling technology that reflects incoming solar irradiance, while emitting thermal radiation to the cold universe and achieving sub-ambient cooling.
This self-cooling technology possesses many advantages, such as a simple structure, easy manufacturing, and low cost. Directly coating this paint on a building’s roof or exterior walls will reduce its surface temperature and save on air-conditioning energy. The technology can be used for cooling automobile, in self-cooling textiles and painting roads to mitigate heat from land.
The following projects by the CityU researchers also won the Gold Medal.
“Aquatic Animal Postmortem Multimedia Analysis Platform” utilises virtopsy techniques such as Computed Tomography, Magnetic Resonance Imaging and 3D surface scanning, to provide insights for the assessment of aquatic animal profiles and biological health locally and globally.
“Super Bamboo – Sustainable Structural Bamboo Materials with High Strength and Multi-function”- includes both mechanical and chemical treatments for densifying natural bamboo without destroying key internal microstructure that are critical for superior mechanical performance.
“Youth Sports Education and Management SaaS platform Based on AI & IoT” developed by AI Motion Sports”- uses advanced technology to digitalise K12 youth sports industry and define the standards of next-generation sports education.
“Damage-healable Antimicrobial Coating Made from Natural Materials”-development and applications of coatings with sustained disinfection abilities for long-term prevention of surface fouling.
“Development of new generation anti-metastasis drugs based on endosomal trafficking”- identifies 6J1/6J2 as potent endosomal trafficking inhibitors that can effectively inhibit tumor progression and metastasis in various experimental mouse models with little in vitro and in vivo toxicity.
These awards at such a high international level demonstrate the excellence of the research carried out at CityU.
