Comparison of malate production rates from CO2 and pyruvate with and without aluminum ions
29 Sep 2020
Researchers at Osaka City University produce malic acid, which contains 4 carbon atoms, through artificial photosynthesis by simply adding metal ions like aluminum and iron. This solves a problem with current artificial photosynthesis technology of only producing molecules with 1 carbon atom and paves the way to exploring the use of CO2 as a raw material.

While the power conversion efficiency of perovskite solar cells (PVSCs) – a future of solar cells – has already greatly improved in the past decade, the problems of instability and potential environmental impact are yet to be overcome. Recently, scientists from City University of Hong Kong (CityU) have developed a novel method which can simultaneously tackle the leakage of lead from PVSCs and the stability issue without compromising efficiency, paving the way for real-life application of perovskite photovoltaic technology.

Because of their unique physical, chemical, electrical and optical properties, two-dimensional (2D) materials have attracted tremendous attention in the past decades. After revealing the realistic strength and stretchability of graphene, nicknamed “black gold”, researchers from City University of Hong Kong (CityU) have carried forward the success by unveiling the high defect tolerance and elasticity of hexagonal boron nitride (h-BN), another 2D material known as “white graphene”. This follow-up study will promote future development and applications of strain engineering, piezoelectronics and flexible electronics.

The COVID-19 outbreak is causing widespread disruption to daily life. Hong Kong people living in cramped subdivided flats with poor hygiene conditions have been particularly hard hit. In light of this alarming situation, Lingnan University (LU) jointly launched “Project Ultra Violite” with NGOs to provide a free, efficient UV disinfection service for 1,000 subdivided flats. It is the territory’s first community-wide programme using UV disinfection technology.

Face masks have become an important tool in fighting against the COVID-19 pandemic. However, improper use or disposal of masks may lead to "secondary transmission". A research team from City University of Hong Kong (CityU) has successfully produced graphene masks with an anti-bacterial efficiency of 80%, which can be enhanced to almost 100% with exposure to sunlight for around 10 minutes. Initial tests also showed very promising results in the deactivation of two species of coronaviruses. The graphene masks are easily produced at low cost, and can help to resolve the problems of sourcing raw materials and disposing of non-biodegradable masks.

A research team from the Department of Computer Science and Engineering (CSE) at The Chinese University of Hong Kong (CUHK) has developed a new Gene Expression Embedding frameworK (GEEK), which uses artificial intelligence technologies in machine learning and natural language processing to study the regulation of gene expression. In contrast to previous works that focused on one or a few regulatory mechanisms at a time, this new framework can study the joint effects of many mechanisms simultaneously. A research article describing this new study has been published in the renowned international science journal Nature Machine Intelligence. The framework may help study the causes of cancers and treatment methods.
