Big Data Center publishes satellite data on BRI urban nighttime light emissions

https://english.news.cn/20230906/80d41d7d0ced4bdea2f6a0bdd2fed8fe/c.html The International Research Center of Big Data for Sustainable Development Goals (CBAS) has released the world’s first atlas of urban nighttime light remote-sensing data, providing support for the research on urban sustainable development. The atlas contains 10-meter resolution nighttime light data on 147 cities in 105 countries around the world. The data were captured […]

Coastal ecosystems are important contributors to China’s CO2 storage

https://www.cas.cn/cm/202309/t20230906_4968761.shtml Coastal blue carbon ecosystems, including mangroves, salt marshes, and seagrass beds, have efficient carbon dioxide sequestration capabilities, so protecting and restoring these ecosystems has become an important “nature-based solution.” China’s coastal blue carbon ecosystem has a total area of 1.44 million hectares and a carbon storage of up to 118 Tg. Among them, the […]

Model suggests that urban areas account for <4% of global land but >70% of global CO2 emissions

https://english.cas.cn/newsroom/research_news/life/202309/t20230907_336139.shtml In a study published in Science of the Total Environment, researchers from the Xishuangbanna Tropical Botanical Garden (XTBG) of the Chinese Academy of Sciences and Hohai University proposed a new method to calculate urban socioeconomic development indexes using a variety of data sources.  Based on the lighting index, business point of interest (POI) data and output […]

CAS QIBEBT: core–shell Au@Nanoplastics as a quantitative tracer to investigate the bioaccumulation of nanoplastics in freshwater ecosystems

https://www.cas.cn/syky/202309/t20230901_4967576.shtml https://pubs.acs.org/doi/10.1021/acs.analchem.3c01666# The Industrial Biogas Research Center of CAS Qingdao Institute of Bioenergy and Process Technology has developed a method for the controlled synthesis of polystyrene core-shell model plastics (Au@NPs) for the quantitative detection of plastics. The surface charge and particle size of the nanoplastic can be regulated by the initiator and reaction time.With six […]

CAS TIB designs synthetic pathway for CO2 to sugar

https://www.sciencedirect.com/science/article/abs/pii/S2095927323005510 The research team of Functional Sugars and Natural Active Substances of CAS Tianjin Institute of Industrial Biotechnology has established a synthetic pathway for the synthesis of hexose from carbon dioxide in a chemical-enzymatic cascade based on the enzymatic reactions of carbon condensation, isomerization, and dephosphorylation in cooperation with CAS Dalian Institute of Chemical Physics, […]

CAS ISA: global greenhouse gas emissions did not decrease over past decade

The report, prepared by the CAS Institute of Space […]

China exports hydrogen tram to Malaysia

https://spc.jst.go.jp/news/230703/topic_2_01.html China’s Zhongsha Zhuzhou Electric Power Machinery Research Institute has developed a hydrogen energy smart streetcar that will be shipped from Shanghai port to Malaysia. The Smart Tram will be used for urban transit services in Kuching, Sarawak, Malaysia. The vehicle uses a hydrogen energy power system from a high-power fuel cell system, giving it […]

Beijing to complete first hydrogen-based carbon trading in September 2023

https://english.news.cn/20230804/48331c3f0f264b7a8bb9a2ca997a79f4/c.html As a hydrogen-based project that can partake in the carbon market trading, the Beijing hydrogen fuel cell vehicle carbon emission reduction project was launched in Beijing’s Daxing District on Thursday. The project is estimated to be able to slash about 24,000 tonnes of carbon emissions annually and is expected to complete the city’s first hydrogen-based […]

Taiwan collaborates with Indonesia on research to reduce and effectively use waste

https://spap.jst.go.jp/other_asia/news/230703/topic_nt_01.html Taiwan University of Science and Technology (Taiwan Tech) is conducting research on waste reduction, sustainable use of materials, and clean production methods through its Science and Technology Innovation Center, which opened last year as a joint initiative with Indonesian academic institutions. Taiwan Tech, Indonesia’s Institute of Technology Surabaya (ITS), Widya Mandala Catholic University (WMSCU), and […]
