Graphene, impermeable to gases and liquids, can easily allow protons to pass through it, suggesting it could be a promising candidate for use in hydrogen fuel cells. Graphene, an atom-thin film of carbon atoms arranged in a honeycomb pattern, has a number of interesting properties that make it an attractive candidate for various technologies. It was previously assumed that unless graphene had defects, sheets would need to be perforated to allow transport through them.
Scientists have identified China's oldest adhesive, in the form of gelatine, from a 3,500-year-old ritual staff in a tomb complex known for its well-preserved mummies in Xinjiang, northwest China. The translucent yellow adhesive was found on a wooden staff inlaid with bone sculpture in the Xiaohe Cemetery in Taklamakan Desert, said Yang Yimin, associate professor with the Chinese Academy of Sciences.
How do you build a sustainable food supply for more than a billion people? This is the monumental challenge faced by scientists in China. At the Chinese Academy of Sciences' facility in the city of Wuhan, a team of biologists from the Institute of Hydrobiology (IHB) is working on ways to increase the production of fish for food. And this team is turning to the University of Ottawa's Department of Biology to better understand the underlying factors that affect the reproduction, development and stress of farm-raised fish.
For tens of thousands of years, modern humans have used the waterways to spread out across the surface of the planet. Major civilizations developed along massive rivers like the Nile in Egypt and the Yellow River in China, and massive water channels propelled the expansion of economies around the world. But in recent decades, according to a team of scientists at the Cold and Arid Regions Environmental and Engineering Research Institute, Chinese Academy of Sciences, in the northwestern Chinese city of Lanzhou, the competition between economic growth and the ecosystem of rivers has triggered a series of environmental crises around the world. In northwestern China, they write in a new study, "many of the inland river basins ... have experienced a common challenge."
Dr. WU Ji, Professor of National Space Science Center, Chinese Academy of Sciences, Beijing, China, was named an IEEE Fellow on November 24 in Piscataway, New Jersey, USA. He is being recognized for leadership in microwave remote sensing and its application to satellite programs. Key technology has been developed under his leadership and direct contribution is the passive microwave interferometric imaging which made China became one of the leading nations in this research area.
Chinese institutions have become a rising power in scientific research, a new global indicator of high-quality science showed. According to the Nature Index 2014 Global, Chinese institutions, led by the Chinese Academy of Sciences, have increasingly contributed to global science. The index ranked institutions based on the number of papers published in 2013.
