Digital technology restores the costume of a Song Chinese from the remains in his tomb

http://j.people.com.cn/n3/2024/0626/c95952-20185818.html Costumes from the Southern Song Dynasty were restored with digital technology at the Huangyan Museum in Taizhou, Zhejiang Province. A digital human named Zhao Boshu from the Southern Song Dynasty was shown wearing a cross-hugging lotus flower patterned bright ground gauze robe and showing off a realistic appearance with a slightly leaning forward pose. This is one of the costumes restored by the digital fashion team of the Zhejiang Modern Textile Technology Innovation Center using virtual reality (VR) technology. Due to the special nature of preservation of clothing cultural relics, the team was unable to observe and photograph these cultural relics from close range, and the only reference material was some photos of the cultural relics provided by the Huangyan Museum. The team had previously used digital media technology and 3D imaging technology to digitally restore the patterns, fabric structure, style and wearing state of the costume excavated from Zhao Boxu’s tomb. The team’s technicians then used 3D technology to restore the physical attributes of the costume by observing the fabric structure of the costume, highlighting the light, soft, thin and transparent characteristics of silk fabric. Using flexibility reproduction technology, the restored digital costume reproduces the realism of moving with the body like real fabric.

http://j.people.com.cn/n3/2024/0625/c95952-20185211.html https://www.nature.com/articles/s41586-022-05379-5 The team of Xie Heping, an academician of the Chinese Academy of Engineering and professor at Shenzhen University, has collaborated with a team from Oriental Electric Group to directly produce hydrogen from seawater using offshore wind power. The team has developed a new method and technology for direct seawater electrolysis hydrogen production in a real marine environment where wave motion cannot be controlled. They also systematically analyzed the interfacial vapor pressure difference due to the difference in the concentration of seawater components in Shenzhen Bay, Guangdong Province and Xinghua Bay, Fujian Province, and elucidated the self-adjustment and adaptation mechanism of the phase transition process due to the dynamic change of concentration. After that, they built a theoretical model of direct hydrogen production without desalination from phase transition seawater in actual wave motion, and simulated the marine environment in the laboratory, achieving stability for more than 500 hours. To verify the feasibility and reliability of the laboratory simulation environment, the team also designed and developed a 1.2 standard cubic meter per hour offshore renewable energy on-site direct electrolysis hydrogen production float without desalination, and achieved direct connection with offshore wind power generation despite the interference of 3-8 grade strong winds and 0.3-0.9 meter waves in Xinghua Bay. After 10 days of stable and continuous operation, the seawater impurity ion rejection rate reached more than 99.99%, and the purity of hydrogen production reached 99.9-99.99%.

2024/06 Mass production of humanoid robots has started in Dalian

http://j.people.com.cn/n3/2024/0624/c94476-20184934.html In its “Guiding Opinions on the Innovation and Development of Humanoid Robots,” the Ministry of Industry and Information Technology MIIT  stated: “Humanoid robots will be a disruptive innovation product following computers, smartphones, and new energy vehicles, and are expected to significantly change the production and lifestyle of humans.” The humanoid robot “Xiao Qi” was developed by Ex-Robots, a company in Dalian. It can answer questions posed by humans, but it can also change the shape of its mouth, facial expressions, and body movements based on the content of the conversation. Mass production of Xiao Qi has started in May 2024, with a goal of 500 units this year. The main clients are listed companies with chain stores and exhibition halls where Xiao Qi is currently mainly handling reception duties. Humanoid robots are rapidly becoming popular in various scenes, which can be attributed to the dramatic development of technologies such as artificial intelligence (AI) and large-scale language models. According to the Humanoid Robot Industry Research Report, China’s humanoid robots have entered the smart stage, equipped with advanced technologies such as AI, machine learning, and computer vision. According to Jiao Jichao, vice president of humanoid robot developer UBTECH Robotics, robots’ understanding has been greatly improved. Robots can interact with humans more naturally and do not need complex operations. Robots can now accurately carry out their tasks based on their own understanding and reasoning. According to Li Boyang of Ex-Robots, a large number of humanoid robot application projects will emerge in the next two years, and the demand for small-scale mass production will peak in the next five years or so. Applications for the business market will appear first, and it will take at least 10 years for mass application in the consumer market. Once humanoid robots become widespread in ordinary households, the market demand will be extremely large, and will be greater than the automobile market. Once robots become an important hardware device in the home, the price should be comparable to that of new energy vehicles. Currently, the price of Ex-Robots’ mass-produced humanoid robots is around 700,000 to 800,000 ¥ (90,000 to 100,000 €). If it is custom-made, it will cost about 1.5 million to 2 million ¥ (200,000 – 250,000 €).

Applying 28 million tons of cotton stalks to high-value-added products

https://www.sciencedirect.com/science/article/abs/pii/S1364032124003770 The Cotton Molecular Genetic Improvement Innovation Team around Fuguang Li at the Cotton Research Institute of the Chinese Academy of Agricultural Sciences has put forward a precise practical application plan and an economically feasible implementation plan for their high-value-added use and industrialization of cotton stalks. China’s cotton production in 2023 was 5.618 million tons, which produced about 28 million tons of stalks. However, at present, most of the cotton stalks are directly returned to the fields or burned, resulting in problems such as resource waste and environmental pollution. Cotton stalks are mainly made of cellulose, hemicellulose and lignin. These components can be converted into high value-added products such as biological materials, biochemicals and biofuels. The study systematically explains the chemical structure of cotton stalks and systematically summarizes research into synthesizing cotton stalks into three types of high value-added products: biological materials, biochemicals and biofuels. By contrasting various conversion methods, it has put forward a plan to maximize the value of cotton stalks.

Samples from moon’s backside arrive in Inner Mongolia

http://en.people.cn/n3/2024/0625/c90000-20185347.html The returner of the Chang’e-6 probe touched down on Earth on June 25, bringing back the world’s first samples collected from the moon’s far side. The return capsule landed precisely in the designated area in Siziwang Banner, north China’s Inner Mongolia Autonomous Region, and the mission is a complete success, according to the China National Space Administration (CNSA). Chang’e-6 is one of the most complex and challenging missions in China’s space exploration efforts to date. Consisting of an orbiter, a returner, a lander and an ascender, it was launched on May 3 this year, and has gone through various stages such as Earth-moon transfer, near-moon braking, lunar orbiting and separation of the lander-ascender combination and the orbiter-returner combination. Supported by the Queqiao-2 relay satellite, the lander-ascender combination landed at the designated landing area in the South Pole-Aitken (SPA) Basin on the far side of the moon on June 2 and carried out sampling work. On June 4, the ascender took off from the moon with samples and entered the lunar orbit. On June 6, it completed rendezvous and docking with the orbiter-returner combination and transferred samples to the returner. The ascender then separated from the combination and landed on the moon under ground control to avoid becoming space junk. The orbiter-returner combination spent 13 days in lunar orbit, awaiting the right opportunity to return to Earth. After completing two moon-Earth transfer maneuvers and one orbital correction, the returner separated from the orbiter and delivered the samples to Earth. “The Chang’e-6 mission represents a significant milestone in the history of human lunar exploration, and it will contribute to a more comprehensive understanding of lunar evolution,” said Yang Wei, a researcher at the Institute of Geology and Geophysics of the Chinese Academy of Sciences. “New samples will inevitably lead to new discoveries. Fascination with the moon is rooted in Chinese culture down the ages, as evidenced by the mythological narrative of Chang’e, a lady who journeyed to and resided on the moon. Now, Chinese scientists are eagerly anticipating the opportunity to contribute to lunar science,” Yang added.

The Dragon Program conference, a major China-Europe science collaboration since 2004,  opened in Lisbon in June, marking the transition from Earth observation plan Dragon 5 to Dragon 6 and included a new agreement on climate change and big data. Organized by China’s Ministry of Science and Technology and the European Space Agency (ESA), the five-day symposium attracted nearly 300 experts and scholars from China and Europe to discuss the achievements of Dragon 5, and introductions to Dragon 6 projects, focusing on the latest developments in Earth observation technology and the application of satellite remote sensing technology in environmental protection and disaster mitigation. At the opening ceremony, China and Europe signed the cooperation agreement for Phase 6 of the Dragon Program, which spans from 2024 to 2028. This agreement covers ten key themes, including land, atmosphere, climate change and big data. Under the agreement, both sides will continue to promote the sharing and application of Earth observation data through collaborative research, academic exchanges, and talent training. Starting in 2024, the China Science and Technology Exchange Center will take over the Chinese side’s management of the Dragon Program, working alongside ESA’s Earth Observation Department. These efforts have fostered a stable joint research team for Earth observation, achieved internationally leading research results, and provided technological support for tackling global challenges such as climate change. Josef Aschbacher, director-general of ESA, said the Dragon Program is one of the longest-standing and most fruitful cooperative projects between China and Europe. He noted that the program has not only facilitated profound exchanges between scientists from both regions, but also promoted the application of technological achievements.
