“Key Technologies and Applications for Beach Protection and Restoration of Complex Coastal Environments” participated by Ocean University of China won the second prize of the National Science and Technology Progress Award.

In addition, Qingdao’s participation in award-winning projects has high “gold content” and broad influence. Among them, the “Fuxing High-Speed Train” project completed by CRRC Qingdao Sifang Rolling Stock Co., Ltd. and CRRC Qingdao Sifang Rolling Stock Research Institute Co., Ltd. won the special prize of the National Science and Technology Progress Award. The “Fuxing” high-speed train is a new generation of high-speed train independently developed by China and with complete intellectual property rights. With a maximum speed of 350 kilometers per hour, China has become the country with the fastest commercial operation of high-speed rail in the world. This record remains to this day. As of the beginning of this year, the “Fuxing” high-speed train has transported more than 2.2 billion passengers.

Enterprise innovation is the fundamental driving force and internal source of innovation. Among the Qingdao award-winners, 9 projects have enterprises taking the lead in completing and deeply participating in them. For example, the “Technological Innovation and Industrialization of Temperature and Humidity Oxygen Magnetic Multi-dimensional Precision Control of Household Preservation Appliances” project led by Haier Smart Home Co., Ltd. and participated by Qingdao Haier Refrigerator Co., Ltd. won the second prize of the National Science and Technology Progress Award; Tsingtao Brewery Co., Ltd. The project “Efficient Breeding and Optimization of Key Technologies and Applications of Food Biomanufacturing Industrial Strain”, as the main completion unit, won the second prize of the National Science and Technology Progress Award.

Gold recovery from waste liquid without chemicals

https://pubs.acs.org/jacsat/article/148/28/29854/5203821/Selective-Gold-Recovery-via-Thermally-Generated?searchresult=1

A new technology recovers gold from waste liquid using naturally occurring micro-droplets at the oil-water interface, simply by moderately heating the oil-water system—without the addition of any reducing agents, adsorbents, or catalysts.

The technology was developed by a team from the China University of Petroleum in Qingdao, in collaboration with researchers from Stanford University.

Drawing on their previous research into geological fluids—where they discovered that large numbers of chemically active micro-droplets are generated at oil-water interfaces under high-temperature conditions—the team formulated a bold hypothesis: “Could we selectively extract gold from complex waste liquids simply by utilizing the chemical properties of these micro-droplets?”

To test this, the team constructed a heat-driven oil-water interfacial reaction system. Moderate heating causes the continuous formation of micro-droplets (5–50 micrometers in diameter) at the oil-water interface. These droplets function like micro-reactors with high redox activity, continuously generating active species such as highly active electrons, hydrogen radicals, and hydroxyl radicals. This process enables the reduction of gold ions in the solution to elemental gold without the need for external reducing agents, catalysts, or adsorbents; furthermore, the coalescence and growth of these micro-droplets allow for the formation of millimeter-sized gold particles.

The study also elucidated the chemical mechanism by which the interfacial micro-droplets selectively recover gold. Experiments demonstrated gold recovery rates of 98.5% from complex aqua regia waste liquid and 97.0% from electronic waste leachate. The recovery time was further reduced through heating and cooling cycles, and a recovery efficiency of over 90% was maintained even when the oil phase was reused. In a scale-up experiment, 500 milliliters of gold-containing leachate were processed to yield 0.5657 grams of solid product. The gold achieved a purity of 99.4%, demonstrating high potential for application as an environmentally friendly technology for recovering precious metals from complex acidic wastewater.

An offshore platform for coastal ecosystem research near Qingdao

https://en.people.cn/n3/2026/0711/c90000-20476703.html

China put into operation a large offshore platform for controlled in-situ experiments regarding coastal ecosystems. Developed by the CAS Institute of Oceanology (IOCAS), the facility is deployed in the Yellow Sea off Rongcheng in Shandong Province.

With a total area of 2,000 square meters and an experimental sea zone of 30,000 square meters, the platform is designed to support a wide range of ecological studies under real marine conditions. Under real seawater conditions, key factors such as temperature, nutrients and dissolved oxygen can be precisely regulated, enabling continuous, full-cycle observation and breaking the technical barrier between natural-sea observation and indoor controlled experiments.

The platform comprises modules for automated monitoring, water regulation, mesocosm ecosystems and logistics support. It enables precise single-factor or multi-factor regulation of temperature, nutrients, dissolved oxygen and other variables, allowing researchers to reproduce scenarios like ocean warming, acidification and eutrophication in a real marine environment. This capability is crucial for understanding how coastal ecosystems respond to both gradual climate trends and extreme events.

China’s coastal waters, where most marine economic activities and ports are concentrated, are hotspots for ecological disasters and risks. These waters, notably, are under mounting stress from climate change, land-based inputs and human activities. The new lab is located in a typical mariculture area of northern China, offering conditions for both natural and farmed ecosystem studies. Researchers can conduct scenario experiments on carrying capacity, ecological resilience, marine heatwaves and hypoxia to identify risk thresholds and optimize aquaculture management. Beyond serving the aquaculture industry, it can provide technical support for disaster prevention, precision restoration and coastal health management, said Sun.

The platform is designed for open international collaboration and will be made available to global research institutions, facilitating joint efforts to tackle pressing marine environmental challenges.

China on Friday put into operation a large offshore platform for controlled in-situ experiments regarding coastal ecosystems, marking a new phase of systematic, intelligent and open coastal ecological research in the country. Developed by the Institute of Oceanology under the Chinese Academy of Sciences (IOCAS), the facility is deployed in the Yellow Sea off Rongcheng in east China’s Shandong Province. It is the country’s largest open-access facility for in-situ coastal experiments, the IOCAS said. (IOCAS/Handout via Xinhua)
