    Spacecraft completes in-orbit refueling
    By Zhao Lei | China Daily | Updated: 2017-06-16 07:57[​IMG][​IMG][​IMG][​IMG]


    The Tianzhou 1 cargo spacecraft has carried out its second in-orbit operation to deliver fuel to the Tiangong II space laboratory, according to the China Manned Space Agency.

    The agency said in a news release on Thursday evening that Tianzhou 1 completed the two-day refueling process at 6:28 pm, adding that the operation was also designed to provide a second verification of the technology and devices used in spacecraft refueling.

    The process involved examining fuel pipes and pumping propellants and oxidizer into fuel containers, the news release said.

    Tianzhou 1, China's first cargo spacecraft, was launched at the Wenchang Space Launch Center in Hainan province on April 20. Developed by the China Academy of Space Technology, it is 10.6 meters long and has a diameter of 3.35 meters. Its maximum liftoff weight is 13.5 metric tons, enabling it to carry up to 6.5 tons of supplies.

    It is the largest spacecraft China has built. Previously, the largest and heaviest craft the country had sent skyward was the Tiangong II.

    Tiangong II has been in space since mid-September and was occupied by two Chinese astronauts from mid-October to mid-November. It is now unmanned.

    The two spacecraft docked on April 22 and the next day started their first in-orbit refueling operation, in which a portion of the fuel carried by Tianzhou 1 was transferred to the space lab over about five days. They have remained connected for the past 54 days, during which they also performed a number of scientific and technological experiments, according to the space agency.

    The remaining fuel carried by Tianzhou 1 was transferred in a second operation on Thursday. Now the cargo spacecraft will undock and then redock with the space lab. It will then undock from Tiangong II once more and begin a three-month independent flight before a third docking.

    In the future, the Tianzhou-series cargo spacecraft will be tasked with bringing supplies of fuel, spare parts and other necessities to China's manned space station, whose construction will begin around 2019.

    Thanks to the Tianzhou 1 mission, China has become the third nation in the world to have in-orbit refueling technology after Russia and the United States.

    The world's first pigs cloned by robotic instrument born in Tianjin
    Peopple's Daily Online | Updated: 2017-07-05 09:28[​IMG][​IMG][​IMG][​IMG]

    Recently, China proved its success in cloning pigs, as test results show the new-born pigs and their surrogate sows are unrelated.


    The two sows gave birth to 13 purebred baby pigs after a 110-day pregnancy in April.

    The Robotics Institute at Nankai University in Tianjin headed the study on cloning pigs derived from somatic cells, in cooperation with the Animal Husbandry and Veterinary Research Institute.

    The technique involved is called somatic cell nuclear transfer, a classic technique used for improving the variety of crops. It transfers the cell nucleus of a somatic cell into an egg without a nucleus. The advantage of this method is that it guarantees the quality of the egg. However, the low rate of success limits the development of this technique.

    Based on this technique, the research group invested an in-situ microanalysis micromanipulator that combined all the functions of testing, analysis, and operation into one instrument. This robotic instrument made a great contribution in the process of removing a nucleus.

    The key challenge is avoiding destroying the delicate cells during the process. Researchers analyzed how much force was applied to cells by the instrument and then adjusted it to make sure the smallest possible force was applied when moving cells and removing nucleuses. The deformational degree of cells decreased from 30~40 mm to 10~15 mm afterward, which remarkably improved subsequent development of cell.

    Group leader Zhao Xin said the research built a connection between cell micro operation and cell development and can help others make more achievements. The research has broad implications, and can be applied to assisted reproductive technology, plants and animals species improvement, family practice, animal production systems, and other areas.

    Maglev train nears completion in Beijing
    By Zhang Yu in Shijiazhuang | China Daily | Updated: 2017-06-15 07:35[​IMG][​IMG][​IMG][​IMG]

    Beijing's first mid - to low-speed magnetic levitation railway line is preparing for its debut later this year.

    Services on Line S1 will run from Shimenying station in western Mentougou district to Pingguoyuan station in Shijingshan district, a transfer station for Line 1.

    The maglev line will have eight stations stretching over 10.2 kilometers and will run at a maximum speed of 100 kilometers per hour. The whole journey will take about 20 minutes, including the time for passengers to get on and off.

    The train, manufactured by CRRC Tangshan Co in Hebei province, has six cars and is designed to carry 1,032 passengers at a time.

    According to the company, 10 trains will be put into use in the first stage of operation.

    The main feature of the maglev train is that it doesn't have wheels, unlike the current metro trains. That makes it more comfortable and safer, according to CRRC Tangshan.

    Using electromagnetic forces, the trains are elevated about 1 centimeter above the tracks, avoiding friction and resulting in a smooth ride.

    Tracks are specially designed to prevent the trains from overturning or derailing, the company said.

    The Chinese Academy of Sciences' Institute of Electrical Engineering was quoted by China Central Television as saying that the magnetic fields of the maglev trains have less effect on human health than TV sets.

    The debugging process for Line S1 is expected to end in November, followed by a monthlong trial run, said Sun Hechuan, deputy general manager of Beijing Enterprises Holdings Maglev Technology Development Co.

    The country's first domestically designed and manufactured maglev line began operating a year ago in Changsha, capital of Hunan province.

    Chinese ultra-sensitive magnetic sensor technology to capture all submarines

    The new magnetometer developed by the Chinese Academy of Sciences can capture the weakest magnetic field in a few kilometers away. The basis of this instrument is the Superconducting Quantum Interferometer (SQUID), which utilizes the principles of quantum mechanics. The SQUID can record changes in the electronic interference situation under the influence of an external magnetic field, which has a discontinuous stepped characteristic.

    In the Chinese Navy's SOSUS system, this new technology is currently China's leading technology in the world, called superconducting quantum interferometer (SQUID). SQUID utilizes the principles of quantum mechanics and a new set of Chinese scientists to develop a new algorithm that captures the weakest disturbance of objects on the Earth's magnetic field in a few kilometers, and its acquired signals are transmitted through the submarine fiber to the ultra-high-speed information processing center, so that experienced anti-submarine experts locked the enemy underwater attack platform accurate location. Once China has applied this technology to the underwater detection network, then all the submarine noise reduction efforts in the United States, Japan and NATO are lost. Because even if the American advanced "sea wolf" class nuclear submarine shut down the engine and all equipment for their own safety , do not make any sound, but will still be found by the SQUID based ultra-sensitive magnetometer network. As a result, the Chinese Navy Y-8Q anti-submarine aircraft (high-new -6), 054A and 056A frigate will surround and attack it.

    SANYA, Oct. 3 (Xinhua) -- China's new manned submersible, on board the ship Tansuo-1, returned to port in Sanya, Hainan Province on Tuesday, after completing deep sea testing in the South China Sea.

    The manned submersible named Shenhai Yongshi, or deepsea warrior, reached a depth of 4,500 meters to test its functions and performance during an over 50-day expedition.

    Bai Chunli, president of the Chinese Academy of Sciences, said in a congratulatory letter that the deep sea tests show the new manned submersible performed well and is another achievement for China in developing deep sea manned submersibles.

    The development of the submersible took eight years and involved over 90 Chinese organizations and companies. All of its core components were domestically made.

    China's manned submersible Jiaolong completed its deepest dive reaching a point of 7,062 meters in the Mariana Trench in June 2012.

    Breakthrough relies on ‘spooky’ phenomenon of quantum entanglement


    PUBLISHED : Wednesday, 21 September, 2016, 12:43pm
    UPDATED : Monday, 12 June, 2017, 12:53pm


    A top Chinese military technology company shocked physicists around the world this week when it announced it had developed a new form of radar able to detect stealth planes 100km away.

    The breakthrough relies on a ghostly phenomenon known as quantum entanglement, which Albert Einstein dubbed “spooky action at a distance”.

    China Electronics Technology Group Corporation (CETC), one of the “Top 10” military industry groups controlled directly by the central government, said on Sunday that the new radar system’s entangled photons had detected targets 100km away in a recent field test.

    That’s five times the “potential range” of a laboratory prototype jointly developed by researchers from Canada, Germany, Britain and the United States last year.

    America’s Defence Advanced Research Projects Agency has reportedly funded similar research and military suppliers such as Lockheed Martin are also developing quantum radar systems for combat purposes, according to media reports, but the progress of those military projects remains unknown.

    Teleportation, the next generation: Chinese and Canadian scientists closer to a quantum internet

    In a statement posted on its website on Sunday, CETC said China’s first “single-photon quantum radar system” had “important military application values” because it used entangled photons to identify objects “invisible” to conventional radar systems.

    Nanjing University physicist Professor Ma Xiaosong, who has studied quantum radar, said he had “not seen anything like this in an open report”.


    “The effective range reported by the international research community falls far below 100km,” he said.

    A military radar researcher at a university in northwestern China said the actual range of the new radar could be even greater than that announced by CETC.

    “The figure in declassified documents is usually a tuned-down version of the real [performance],” he said. “The announcement has gone viral [in the radar research community].”

    ‘Handshake’ shows China’s quantum satellite performing even better than expected, says scientist

    The scientists said they were shocked because, until recently, the idea of quantum radar had remained largely confined to science fiction.

    Quantum physics says that if you create a pair of entangled photons by splitting the original photon with a crystal, a change to one entangled photon will immediately affect its twin, regardless of the distance between them.

    A quantum radar, generating a large number of entangled photon pairs and shooting one twin into the air, would be capable of receiving critical information about a target, including its shape, location, speed, temperature and even the chemical composition of its paint, from returning photons.

    China’s hack-proof quantum satellite leap into space leads the world

    That sounds similar to a normal radar, which uses radio waves, but quantum radar would be much better at detecting stealth planes, which use special coating materials and body designs to reduce the radio waves they deflect, making them indistinguishable from the background environment.

    In theory, a quantum radar could detect a target’s composition, heading and speed even if managed to retrieve just one returning photon. It would be able to fish out the returning photon from the background noise because the link the photon shared with its twin would facilitate identification.

    However, Ma, who was not involved with the CETC project, said serious technical challenges had long confined quantum radar technology to the laboratory.

    The photons had to maintain certain conditions – known as quantum states – such as upward or downward spin to remain entangled. But Ma said the quantum states could be lost due to disturbances in the environment, a phenomenon known as “decoherence”, which increased the risk of entanglement loss as the photons travelled through the air, thus limiting the effective range of quantum radar.

    Quantum teleportation breakthrough earns Pan Jianwei’s team China’s top science award

    The CETC breakthrough benefited largely from the recent rapid development of single-photon detectors, which allowed researchers to capture returning photons with a high degree of efficiency.

    CETC said the quantum radar’s advantage was not limited to the detection of stealth planes.

    The field test had opened a “completely new area of research”, it said, with potential for the development of highly mobile and sensitive radar systems able to survive the most challenging combat engagements.

    Quantum radar systems could be small and would be able to evade enemy countermeasures such anti-radar missiles because the ghostly quantum entanglement could not be traced, it said.

    The company said it had worked with quantum scientists at the University of Science and Technology of China in Hefei, Anhui province, where many quantum technology breakthroughs have been achieved, including the world’s longest quantum key distribution network for secured communication and the development of the world’s first quantum satellite.

    China powers up new radar tech to unmask stealth fighters


    UPDATED : Wednesday, 27 September, 2017, 11:28pmhttp://www.scmp.com/news/china/soci...powers-new-radar-tech-unmask-stealth-fighters

    Chinese arms firm tests T-ray system designed to penetrate anti-detection coatings on aircraft

    China’s biggest arms manufacturer has tested a new instrument to detect stealth aircraft, technology that could be a military “game changer” if mounted on a satellite or plane, scientists say.

    China North Industries Group Corporation tested a device capable of generating terahertz radiation with unprecedented power at a military research facility in Chengdu, Sichuan province, last week, Science and Technology Daily reported on Monday.

    Terahertz radiation, or T-rays, can penetrate composite materials to reach underlying metallic layers and is widely used in industrial plants to spot product defects.

    Terahertz radars are already capable of finding a concealed weapon in a crowd from hundreds of metres away, and a more powerful version is under development to put on an early warning aircraft or satellite to identify and track military aircraft, including the US’ F-22 and F-35 stealth fighters.


    Attempts to realise military applications for T-ray technology have been limited by the bulk and low power output of terahertz generators. The rays fall on the spectrum between microwaves and light and cannot be produced by conventional radio or optical devices.

    The report said the new device could generate stable, continuous radiation at an average level up to 18 watts, and terahertz pulses with peak power close to one megawatt, on par with some military radars.

    A technical executive at a vendor in China for T-ray devices used in F-35 manufacturing said the reported power levels of the device were “more than a million times higher than the power of the T-ray device used to measure the thickness of coatings on the F-35”.

    “The radar-absorbent coatings on the F-35 will look as thin and transparent as stockings if [the Chinese instrument] is as powerful as they claim,” the executive said.

    “It looks like they will soon be able to have an echo image of the F-35 with some high-definition details ... from a respectable distance.”

    China has claimed that some of its existing very-high-frequency military radar can detect traces of stealth aircraft but doubters say the microwaves from those devices would be absorbed or deflected by stealth materials.

    Qi Jiaran, deputy director of the department of microwave engineering at the Harbin Institute of Technology, said the new instrument could be a game changer.

    Qi, a terahertz imaging specialist not directly involved in the Chengdu project, said the report suggested that China had made a breakthrough in some key technology and components.

    But the technology was still bulky and could not be fitted easily on a plane or satellite.

    “Field deployment may require power output at the kilowatt level. There is still a long way to go before we can monitor stealth fighters or bombers from space,” Qi said.

    The new instrument was developed by the China Academy of Engineering Physics in Mianyang, the nation’s largest research institute for the development and production of nuclear weapons.

    According to the academy’s website, efforts were under way to increase the device’s power output and shrink its size for military applications.

    [​IMG]In 2014, researchers from the Chinese Academy of Sciences (CAS), together with Tsinghua University researchers, published a paper in Science China Technological Sciences, titled “Liquid Phase 3D Printing for Quickly Manufacturing Conductive Metal Objects with Low Melting Point Alloy Ink.” The paper, which discussed how to more quickly and affordably 3D print using metal materials, was ahead of the curve, as 3D metal printing is now one of the fastest growing aspects of the 3D printing technology field. The researchers postulated that unconventional methods, like liquid phase 3D printing, could potentially solve the issues. The two Chinese educational institutions didn’t stop their work with 3D liquid metal printing there, but soldiered on, and recently published some brand-new research.

    [​IMG]
    XJet liquid metal inks.

    Family-owned Vader Systems and Israel-based startup XJet are two of the bigger players in the liquid metal 3D printing game, while 3D printing artist Ioan Florea used liquid metal 3D printing techniques to make his stunning Gran Torino piece of abstract art. Tsinghua University’s Jing Liu, who was a co-author on the 2014 paper, also co-authored a research paper published earlier this month in Materials & Design, titled “3D printing for functional electronics by injection and package of liquid metals into channels of mechanical structures.” Other co-authors of this paper include Jin-Rong Lu and Yong-Ze Yu, both with the Technical Institute of Physics and Chemistry at the Chinese Academy of Sciences (TIPCCAS).

    The research paper presents a more “developed approach” of how the scientists were able to incorporate mechanical structures and liquid metals for functional electronics.

    [​IMG]“With the fabrication freedom and high efficiency introduced by 3D printing, such technology has been explored in the electronic manufacturing processes. In the present work, we reported a developed method for the fabrication of functional electronics with liquid phase electronic circuits. The technique involves printing hollow channels within elastomer structures via fused deposition modeling (FDM), then injecting and encapsulating liquid metal to form electrical traces. The process parameters in printing elastomer objects and the design of hollow channels were investigated via the extrusion experiments. The influence of flow rates on liquid metal injection was also studied under pressure injection. Based on these discussions and validations, the relationships between process parameters and the printing structures were demonstrated, and the flexible substrate with hollow channels was successfully printed by optimization of the process parameters. Moreover, a probe signal circuit has been fabricated to demonstrate the ability of injecting and packaging liquid metal into 3D printed structures for functional electronics,” the paper states.

    [​IMG]
    Graphical abstract of research paper

    In layman’s terms, the liquid metal channels are formed into a flexible 3D printed part through the use of an injection technique. The researchers concluded that layer thickness, as well as the heating temperature, might play an important role in printing elastomer material into mechanical structures that feature hollow channels. Elastomers are versatile, with both thermal and electrical insulation, which is why they’re so popular in smart biomedical devices and electronics; these applications both need adaptable, flexible material, and elastomers fit the bill.

    [​IMG]The circular channel is the best option to use in order to reduce the geometry of the structure’s hollow channels. Then, the lower flow rates will improve the liquid metal’s overall fill effect. The technology could be used in a variety of applications, due to its inherent flexibility.

    Chinese T800 kiloton carbon fiber production line
    Jun 8, 2016 | Industry
    China’s first commercial-scale production line for carbon fiber T800 went operational at the end of May 2016. This is an important development because China could not rely on imported high-end carbon fiber. Having access to such advanced materials will enable China to innovate further in areas such as aerospace, defense, (wind) energy, and automotive.

    Why is it such a big deal?
    Currently, carbon fiber is still under embargo. This means that foreign companies are not allowed to export it to China. Therefore, China must rely on its own technology and supply. Up to now China was only able to operate small scale production of T800 carbon fiber. (T800 is an indicator for the quality and properties of the fiber.) If the news sources are correct, Zhongfu Shenying Carbon Fiber can now produce such fibers at commercial scale. Such advances will surely help China. For example, it can help with future aircraft manufacturing, advance defence technologies and in producing aerospace materials. Those areas had difficulties up to now because of a limited supply of high-end carbon fiber. To a lesser extent it will also have benefits for the (wind) energy and automotive sector. While lower-grade carbon fibers are also used in those two industries, this is mainly because of the current high cost of high-end carbon fiber.

    Now that a Chinese company can make large amounts of T800 carbon fiber by itself, the carbon-fiber production in China moved to a new level.

    Carbon Fiber Production in China
    The first T800 production line in China was operational in 2012 and had an annual production scale of 25 tons. The Lianyungang development zone accounts for about two-thirds of Chinse carbon fiber production capacity. According to industry estimates, the production capacity will reach easily over 10,000 tons nowadays.

    Applications
    The T800 fiber is currently one of the highest strength carbon fibers that are produced in the world. The applications are broad: it is used in the field of aerospace and other fields.

    China is considering more than just military applications for its improved carbon fibers. The carbon can also be used in civil aircraft. According to sources, the Chinese companies are looking into options to use more and better carbon in the C929 widebody aircraft of COMAC. This plane will follow-up the C919 and is planned to conduct its first flight in 2022 and be put into production in 2025. The current C919 only uses carbon fiber in its tail and secondary structures.

    However, there are even ambitions to supply and improve the global market. One company: Jiangsu Hangke Composite Materials Technology was willing to discuss the properties of its materials at an open convention. Jiangsu Hangke is associated with the government’s Chinese Academy of Sciences.

    Zhongfu Shenying Carbon Fiber Co.
    The recently opened T800 production line is developed by Zhongfu Shenying Carbon Fiber, in the Lianyungang development zone. This development zone is based in Jiangsu Province. The line is replacing a T700 production-line which was put into operation in 2012.

    [​IMG]Last year the company also progressed intensely. The T700 carbon fiber 5,000-ton production line was made operational. At the same time a T8000 carbon 100-ton production-line was completed and made operational. The company has become the third company to achieve dry jet wet spinning carbon fiber production. Zhongfu Shenying follows the Japanese company Toray and the USA Hexcel.

    Moreover, Zhongfu Shenying Carbon Fiber is taking the role as a Chinese carbon fiber industry leader. Some say that the T800 carbon fiber by Zhongfu Shenying is of a higher level than similar foreign products. In theory this technology-level could completely replace the imported carbon fiber.

    In 2014-2015, almost all sales of the factory were T700 products. In 2016 the company expects to deliver a total of 2200 tons of carbon fiber to meet the market demand. Although there is currently a downward pressure on the economy, the company already had a profitable first quarter. The sales in this quarter doubled compared to the year before.

    Production Technique
    Compared to traditional wet spinning, dry-wet spinning technology has several advantages. Those are high production efficiency, good carbon fiber quality and low production cost. Currently, 80% of carbon fiber production is via dry-jet wet spinning. The international carbon fiber industry leaders are known to the dry jet-wet spinning technology. Zhongfu Shenying began in 2008 with dry-jet wet spinning to close the technological gap between China and the West.

    How Does Carbon Fiber Work
    The T-number indicates the strength of the fibers. These fibers are impregnated with resin. The impregnated fibers are then baked to create a carbon-fiber-reinforced plastic composite.

    In comparison: the American Toray states that their tensile strength of their T1000G has a rating of 6,370 megapascal (MPa). Moreover, Toray’s T800S has a rating of 5,880 MPa. While the Chinese Jiangsu Hangke states that its T800 has a strength of 5,709. In comparison: the T300 carbon-fiber by Toray has a rating of 3,540 MPa-strength, which has been used for about three decades.

    LONDON, March 22, 2017 /PRNewswire/ -- As a new generation of reinforced fiber featuring excellent mechanical property and chemical stability, carbon fiber is the one with the highest specific strength and specific modulus among mass-produced high-performance fibers.

    Global carbon fiber demand approximated 83,000 tons in 2016, a 12.0% increase from a year ago. China, one of the world's leading sources of carbon fiber demand, consumed 19,000 tons, 22.9% of the global total. However, China relies heavily on imported carbon fiber products (particularly high-performance ones) because of its outdated production techniques and inadequate production capacity. Only 24.9% of carbon fibers were produced locally in China in 2016 and the localization rate is expected to exceed 35.0% in 2021 along with technological advances.

    Carbon fiber and its composites are primarily applied to aviation & aerospace and wind power fields which together accounted for 46% of the world's demand in 2015, compared with no more than 15% in China; sports and leisure fields made up more than 50% globally in 2015 but has suffered a decline in percentage as automobile/wind power/aviation & aerospace industries develop in recent years.

    Carbon fiber and its composites industry will be mainly driven by automobile, wind power, and /aviation & aerospace fields, especially new energy vehicles. Carbon fiber materials can significantly reduce the weight of vehicle body, thus saving energy, reducing emissions, and increasing mileage. However, due to high costs, carbon fiber is chiefly used in Ferrari, BMW and other luxury models. As carbon-fiber recycling industry develops, the costs will decline, enabling its application to Toyota, Ford, and other middle-end models.

    As carbon fiber is produced with sophisticated production processes and advanced technology, China, isolated from these technologies and equipment because of political factors, lags far behind foreign countries.

    1) Product: Japan-based Toray has started research into T2000 carbon fiber (10 times as much as the strength of T1000 carbon fiber and no impurities during polymerization) in 2017, while China just achieves mass production of T800 carbon fiber.

    2) Enterprise: Japanese Toray, Teijin, Mitsubishi Rayon, U.S. Hexcel, Cytec (acquired by Belgian Solvay), and China's Formosa Plastics take the lion's share of global carbon fiber market. After the acquisition of U.S. Zoltek, Toray holds a 30% share of global market as a whole and over 40% share of large-tow carbon fiber market specifically. By contrast, there are only six Chinese enterprises with production capacity of 1000t and above/a each including Zhongfu Shenying Carbon Fiber, Jiangsu Hengshen Fiber Material, and Bluestar Fibres, claiming a combined global share of less than 15%.
