China's first Mars simulation base will be built in Northwest China's Qinghai province, China News Service reported on Tuesday. Located in Dachaidan Hongya region of Haixi Mongolian and Tibetan autonomous prefecture, a hinter land of Qinghai-Tibet Plateau, the base will be established in Qaidam Basin. The area's landform, natural landscape and climate condition resemble closely to those of Mars, said Wang Jingzhai, the prefecture's deputy Party chief. Spread over 95,000 square kilometers of desert, the area has China's largest Yadan landform, or dry areas with wind erosion landscape. It also has other elements, such as mountain, prairie, Gobi desert, river and lake. Adjacent to many tourist attractions along the Hexi Corridor, a part of the Silk Road in Gansu province, the Mars simulation base will be turned into a cultural and tourist experience base that combine elements of "science, science fiction, nature, ecology and culture", said Liu Xiaoqun, director of lunar and deep space exploration general department, Chinese Academy of Sciences. The base will comprise two functional areas - "Mars community" and "Mars campsite" - which will be connected by road but invisible to each other, Liu said. As the only one of its kind in China, the base has filled the gap in science practice education base that combines the fields of space, astronomy, geology, meteorology and new energy, Liu said. plastic wristbands ukcustomise fidget spinner24 hour wristbands coupondebossed wristbandrubber bracelet makeruv bracelet
HEFEI - Chinese researchers have developed a new material that can absorb heavy metal ions from fertilizer, decreasing environmental pollution. The material, a nanocomposite, was developed by a team led by Wu Zhengyan of the Hefei Institute of Physical Science under the Chinese Academy of Sciences. It can "grab" arsenic and copper ions from manure with high efficiency. The results were published in the Journal of Agriculture and Food Chemistry. Heavy metals in animal fodder leave the manure of domestic animals with high levels of heavy metal ions such as arsenic and copper. As a result, organic fertilizer made from the manure also contains heavy metals, which can cause damage to the environment as well as human body. Using clay and charcoal, Wu's team managed to develop a material that can absorb the heavy metal and keep the ions away from crop roots. The material is environmentally friendly, easy to make and cost-efficient, providing a good solution to bottlenecks in the livestock and fertilizer industries, Wu said.
