HKU chemist-led research generates industrial-competitive materials and technologies for organic light-emitting devices (OLEDs) and organic photovoltaics

A multi-institutional team led by Professor Vivian Yam of HKU’s Department of Chemistry has developed robust phosphorescent OLED materials, the superior performances of which have attracted a lot of interests from industry. An exclusive license agreement on OLED material patents has been executed with one of the world’s leading OLED display manufacturers. The licensing is anticipated to realise next-generation OLED technologies.

HKU astronomers promote stargazing manners and dark sky conservation

The HKU Physics Department has been conducting comprehensive research on the light pollution conditions all around Hong Kong for over a decade through the Hong Kong Night Sky Brightness Monitoring Network. Results from the Monitoring Network clearly indicate light pollution is serious in Hong Kong, and the actual number of meteors observable is closely related to the level of light pollution: the more serious the light pollution is, the smaller the numbers of stars and meteors observable. The measured night sky brightness data collected also allows for more realistic estimates of the number of meteors observable. To promote dark sky preservation, the Department is launching the “Be a responsible stargazer • Enjoy the meteor shower” Campaign to encourage the adoption of proper stargazing manners, and to promote reducing light pollution. The Department has also prepared a series of educational infographics for non-experts on meteor showers and dark sky preservation and it is available for free at the public website: http://nightsky.physics.hku.hk/KE/201718/.

HKU Professor Kenneth Leung conferred fellowship by Society of Environmental Toxicology and Chemistry

Professor Kenneth Leung Mei-yee of the Swire Institute of Marine Science and School of Biological Sciences of HKU was conferred as a Fellow of the Society of Environmental Toxicology and Chemistry (SETAC) in recognition of his contributions to ecotoxicology, environmental chemistry, risk assessment and/or life cycle assessment. There are only 57 SETAC Fellows around the world.

Knowledge Exchange Awards 2017

The annual Faculty Knowledge Exchange (KE) Awards recognise each Faculty’s outstanding KE accomplishment that has made demonstrable economic, social or cultural impacts to benefit the community, business/industry, or partner organisations. Results of the 2017 Faculty KE Awards are now available.

HKU and Kyoto U reveal a new strategy to enhance the efficiency of cereal straw for biofuel production

Researchers from HKU and Kyoto University (Kyoto U) revealed a new strategy to allow cellulose in rice straw to release its fermentable sugar more efficiently. Currently, expensive and complicated procedures are required to loosen lignin, a complex polymer which provides mechanical strength and structural integrity in plants, in order to utilise cellulose more efficiently during the production of bioethanol. According to the findings by HKU plant biochemists Dr Clive Lo Sze-chung and Dr Lydia Lam Pui-ying and Kyoto U lignin specialist Dr Yuki Tobimatsu, when flavone synthase II (FNSII), a key enzyme involved in tricin synthesis was knocked out, the lignin content in rice straw was reduced by approximately one-third, the yield of glucose from cellulose degradation was increased by 37% without any chemical treatment. In other words, the efficiency of ethanol production can be enhanced at a lower treatment cost for lignin.

HKU Stephen Hui Geological Museum holds exhibition on private mineral collections in Hong Kong

The HKU Stephen Hui Geological Museum will hold in collaboration with the Mineralogy Society of Hong Kong a "Mineral Collections in Hong Kong" exhibition from March 3 to August 31, to showcase over 200 precious minerals from 18 private collectors in Hong Kong. The exhibits include one of the best gemmy single crystals of Tanzanite from Merelani Mine, a very rare large gem quality Aquamarine on Albite with large fluid inclusions from Balochi, Gilgit-Baltistan, Pakistan, and a 18 cm large gemmy Rhodochrosite on Quartz from the famous Sweet Home Mine in Colorado, U.S.A.. The mineral display cabinet of the late Dr Stephen Hui Sze-fun with a selection from his private collection is also included.

HKU conducted the first demographic study of the Chinese white dolphins in the Pearl River Estuary and urges conservation of dolphin critical habitat

A demographic study of the Chinese white dolphins inhabiting the Pearl River Estuary, led by Dr Leszek Karczmarski, Associate Professor at the HKU School of Biological Sciences, revealed that the PRE dolphin population is declining approximately 2.5% per year and is fast approaching its viability threshold. The findings indicated that the PRE dolphin population is deemed to become extinct unless effective conservation measures can rapidly reverse the current population trend.
