Novel perovskite material with a special structure can generate hydrogen without cocatalyst

Hybrid organic–inorganic perovskite can be used in photocatalytic hydrogen generation. However, the traditional lead-based perovskite contains the toxic metal lead, therefore its application is hindered. Recently, a joint research team led by a scientist from City University of Hong Kong (CityU) has achieved a breakthrough in fabricating a novel lead-free perovskite material with a special structure. Without using cocatalyst, this material showed a three-fold improvement in the efficiency of solar-to-hydrogen energy conversion.

Pioneering research on nanomaterials and green concrete - CityU scholar elected Foreign Member of Academia Europaea

 Professor Liew Kim-meow, a renowned engineer and Chair Professor in the Department of Architecture and Civil Engineering at City University of Hong Kong (CityU), has been elected Foreign Member of the Academia Europaea for his significant contributions in engineering science. He feels privileged to be elected and the membership allows him more opportunities to interact with experts in the fields of civil engineering and other disciplines.

Artificial visual system of record-low energy consumption for the next generation of AI

A joint research led by City University of Hong Kong (CityU) has built an ultralow-power consumption artificial visual system to mimic the human brain, which successfully performed data-intensive cognitive tasks. Their experiment results could provide a promising device system for the next generation of artificial intelligence (AI) applications.

A powerful computational tool for efficient analysis of cell division 4D image data

A joint research team co-led by City University of Hong Kong (CityU) has developed a novel computational tool that can reconstruct and visualise three-dimensional (3D) shapes and temporal changes of cells, speeding up the analysing process from hundreds of hours by hand to a few hours by computer. Revolutionising the way biologists analyse image data, this tool can advance further studies in developmental and cell biology, such as the growth of cancer cells.

Crowd motion experiment reveals why crowds synchronise footsteps

Research co-led by academics at City University of Hong Kong (CityU) has discovered that the phenomenon of human self-organisation known as synchronisation forms spontaneously to avoid inter-person collisions when the safety distance between pedestrians seems insufficient. The findings provided insights in preventing pedestrian synchronisation-induced wobbling effect in structures, ensuring pedestrian and transportation safety.
