New CityU exfoliation technique “recovers” biomaterial’s piezoelectricity
Piezoelectric materials are applicable in the biomedical field, and if they can be biocompatible and degradable, it will be a big step towards real applications. Recently, a research team at City University of Hong Kong (CityU) developed a simple exfoliation method to prepare ultrathin films of small intestine tissues from sheep.

Physical mechanisms explaining DNA and RNA twist changes
The double-helix structure of DNA deforms by environmental stimuli, which will then affect gene expression, and eventually trigger a sequence of cellular processes. Recent researches led by a physicist from City University of Hong Kong (CityU) observed substantial DNA deformations by ions and temperature changes.

Generating ultra-violet lasers with near-infrared light through “domino upconversion” of nanoparticles
A collaborative research team co-led by researchers from City University of Hong Kong (CityU) developed a new approach to generate deep-ultraviolet lasing through a “domino upconversion” process of nanoparticles using near-infrared light, which is commonly used in telecommunication devices.

CityU scientists reveal new neurocircuitry essential for animals to sense environmental cues of imminent danger
Inborn defensive behaviours, such as flight, freeze and fight, are crucial for animals to survive in a dangerous environment in nature. Neuroscientists from City University of Hong Kong (CityU) recently revealed the essential neurocircuitry that is fundamental for animals to perceive and integrate environmental cues to initate defensive behaviour.

An efficient electrochemical intercalation method for high-yield production of TMD nanosheets
Two-dimensional (2D) transition metal dichalcogenides (TMDs), an emerging class of materials that can be used as semiconductors and insulators, have promising potential in various applications due to their unique properties. But the reliable production of these atomically thin 2D materials has been challenging.

CityU’s research found clothes dryers are an overlooked source of airborne microfibers
It is well known that washing clothes can release a large number of microfibers into wastewater, but it is unclear whether drying of clothes would have any impact on the environment. A pilot study by scientists from City University of Hong Kong (CityU) reports that a single clothes dryer can discharge up to 120 million microfibres annually — 1.4 to 40 times of that from washing machines.
CityU, HKUMed and Gleneagles Hospital Hong Kong join hands to introduce portable negative pressure ventilation system in hospital emergency room to reduce COVID-19 cross-infection risk
