Edge-breaking research efforts by faculty members from the College of Science (CSCI) contributed in achieving the UN’s Sustainable Development Goals.
The State Key Laboratory of Marine Pollution (SKLMP) of City University of Hong Kong (CityU) received approval from the UNESCO Intergovernmental Oceanographic Commission (IOC) Sub-Commission for the Western Pacific (WESTPAC) to establish the first UNESCO regional training and research Centre (the Coastal-COMMIT Centre, also known as the “Centre”) on coastal contaminant monitoring and marine innovative technologies in Hong Kong for the Western Pacific region.
Perovskite solar cells (PSCs) are considered a promising candidate for next-generation photovoltaic technology with high efficiency and low production cost, potentially revolutionizing the renewable energy industry. However, the existing layer-by-layer manufacturing process presents challenges that have hindered the commercialisation of this technology.
A research team co-led by chemists from City University of Hong Kong (CityU) recently discovered novel, highly effective anticancer agents with tridimensional structures, which have high anticancer activity, low toxicity and the ability to overcome drug resistance in cancer cells.
Organic photovoltaics (OPVs) are a promising, economical, next-generation solar cell technology for scalable clean energy and wearable electronics. But the energy conversion loss due to the recombination of photogenerated charge carriers in OPVs has hindered further enhancement of their power conversion efficiency (PCE). Recently, researchers from City University of Hong Kong (CityU) overcame this obstacle by inventing a novel device-engineering strategy to successfully suppress the energy conversion loss, resulting in record-breaking efficiency.
A multinational team of researchers, co-led by a City University of Hong Kong (CityU) physicist, has found that a novel metallic crystal displays unusual electronic behaviour on its surface, thanks to the crystal’s unique atomic structure. Their findings open up the possibility of using this material to develop faster and smaller microelectronic devices.
The metal-carbon dioxide battery is a promising and environmentally friendly technology, but its energy efficiency is limited. Recently, a research team co-led by chemists from City University of Hong Kong (CityU) discovered an innovative way to overcome this problem by introducing an unconventional phase nanomaterial as a catalyst, boosting battery energy efficiency up to 83.8%. The study reveals a novel design of catalysts for the new generation of meta-gas batteries that can contribute to carbon neutral goals.
