A research team led by scientists of City University of Hong Kong (CityU) has recently discovered the disordered nanoscale layers at grain boundaries in the ordered intermetallic alloys. The nanolayers can not only resolve the irreconcilable conflict between strength and ductility effectively, but also maintain the alloy’s strength with excellent thermal stability at high temperatures.

Lead halide perovskite semiconductors exhibit superb optoelectronic properties and have been broadly applied in research fields like solar cells, photoelectric sensors and laser devices. However, the weakness of easy degradation in water hinders the application of perovskite semiconductors. A research team led by scientists from City University of Hong Kong (CityU) has developed a novel synthesis method of perovskite materials to overcome this problem.

While scientists still don’t fully understand the diverse nature of RNA molecules, it is believed that the proteins binding to them, called RNA-binding proteins, are associated with many disease formation. A research led by biomedical scientists from City University of Hong Kong (CityU) has developed a novel detection method, called CARPID, to identify binding proteins of specific RNAs in the living cells. It is expected the innovation can be applied in various cell research, from identifying biomarkers of cancer diagnosis to detecting potential drug targets for treating viral diseases.

In the era of smart cities and amid the global outbreak of Covid-19, connecting through the internet is getting more important than ever. Researchers have been working day and night on advancing the optical data transmission network to address the demand for faster transmission speed. An international research team has developed a new technology that is equipped with a special chip made by a scientist from City University of Hong Kong (CityU). The team broke the spectral efficiency world record for optical data transmission with a single integrated photonic chip. This allows the transmission speed as fast as downloading 1,000 high-definition movies in less than a second!

Haze episodes occasionally happen in mainland China. A research team comprising scientists from the School of Energy and Environment at City University of Hong Kong (CityU) has suggested a much less explored pathway that could contribute significantly to the formation of sulfate, one of the major pollutants found in haze episodes.

Researchers from the School of Data Science, City University of Hong Kong (CityU) and the Academy of Mathematics and Systems Science, Chinese Academy of Sciences examined the impact of the last global financial crisis and China's economic stimulus programme on the financial system. Using real-world data, they modelled and characterised the evolution and dynamics of the whole guarantee network for the first time, in order to better understand the potential systemic risks caused by firms’ failures. Their findings are particularly valuable in today’s situation.

To achieve fast and highly sensitive profiling of miRNAs, a research team from City University of Hong Kong (CityU) has developed a novel intracellular biopsy technique that isolates targeted miRNAs from living cells within around 10 minutes by using diamond nanoneedles. The technique is simple and can be applied to other aspects, from the nucleic acid testing of viruses (e.g. COVID-19) to early cancer screening.

Considering hydrogen as a clean energy for future, scientists have been striving to develop novel processes to produce hydrogen efficiently and cost-effectively. A team comprised of scientists who specialized in structure materials at City University of Hong Kong (CityU) has developed a high-performance electrocatalyst based on an innovative concept originally for developing alloys. The new electrocatalyst can be produced at large scale and low cost, providing a new paradigm in a wide application of hydrogen production by electrochemical reaction in future.
