Research led by Professor Philip C. Y. Chow and his PhD student Ms. Yumeng Song from the Department of Mechanical Engineering under the Faculty of Engineering of the University of Hong Kong (HKU), has revealed how minute structural modifications in advanced perovskite materials critically influence their light-emission properties. This study, conducted in collaboration with research teams from The Hong Kong Polytechnic University and the Southern University of Science and Technology, provides valuable insights and practical guidance for designing brighter, more efficient, and versatile materials. The findings could accelerate the development of next-generation optoelectronic and quantum devices.

A new study published in Biochar reveals that biochar, a carbon rich soil amendment widely used to improve soil health and reduce pollution, continues to influence the movement of veterinary antibiotics in farmland soils even after five years in the field. The work shows that biochar’s ability to retain pollutants changes in surprising ways over time, shifting from adsorption driven effects in the first year to soil structure driven mechanisms after long term aging.

An Osaka Metropolitan University-led study evaluated abnormal genes and immune cell composition in canine hepatocellular carcinoma through RNA sequencing. 

The transportation sector, the second-largest emitter of global greenhouse gases, is undergoing a transformation with electrification and subsidies aimed at reducing its carbon footprint. Yet, a critical aspect often overlooked is the role of logistics in global trade and how geopolitical decisions can undermine these efforts. This study sheds light on the impact of suboptimal logistics on greenhouse gas emissions, using recent geopolitical restrictions between Russia and Western countries since 2022 and a scenario of reduced trade through the Red Sea observed in 2024.

The rational design of platinum-based electrocatalysts with optimized metal-support electronic interactions remains a fundamental challenge in achieving atom-efficient hydrogen evolution reaction (HER).
