I think China indeed spent a lot more than $3 billion

Only about US $3 billion??

Why china is spending so low on science and technology for next five years ?????????

India is spending US$ 24 billion on Science and Technology

India is spending 8 times bigger amount US$ 24 billion against china's US$ 3 billion

Chinese 'container hospitals' ready to deploy in Africa
Li Jiao
13 June 2013 | EN


Africa's first 'container hospital', developed by Chinese scientists, could be ready for use by the end of the month (June), following two years of development.

It will be located in either Cameroon or Namibia, depending on government approval.

Its developers say that the hospital's ten component containers can be slotted together in different configurations, like toy blocks, depending on individual countries' needs.

Each hospital consists of ten containers with rooms for general clinics, waiting patients, treatments, a pharmacy and back-up power supply. The hospitals developers say they can be used for decades if properly maintained, and are intended for long-term service. It is hoped that several African countries will eventually benefit.

In 2010, Liu Yandong, the new Chinese vice premier, signed a memorandum to develop a portable hospital suitable for Africa. The concept was subsequently developed at The Low Cost Health Programme Centre (LCHPC) at the Shenzhen Institutes of Advanced Technology (SIAT), part of the Chinese Academy of Sciences.

China’s Ministry of Science and Technology has led and funded the project, so far to the tune of 14 million renminbi (US$2.2 million). However, according to Zhou Shumin, director of LCHPC, the funding is not enough, and so the ministry has pledged to invest further.

Zhou says that container hospitals function in the same way as general hospitals — the only key difference is the size.

They are intended for use near sizeable settlements — at least a suburban village — and need a flat, open site more than 2,000 square metres in size as well as necessary infrastructure, including a power supply and tap water.

China has also developed 'container clinics', smaller versions with one to three containers.

According to Zhou, the container hospital needs at least four doctors to run, while the clinic needs one.

Ten African doctors were trained to use the hospitals and clinics last year as part of a trial. They will also be trained in the actual hospitals before use. Medical student Wu Haili, from Gabon, says: "The fact that the hospital is easy to assemble, its low cost and its mobility all make it very suitable for under-developed areas in Africa".

"In Africa, some areas are short of basic health equipment, particularly in areas far away from big cities. The container hospital will provide them with the opportunity to see a doctor more quickly."

China plans to give hospitals and clinics to six African countries this year. At the end of July, it plans to send two container hospitals to Cameroon and Namibia, followed by clinics to Kenya, South Africa, Tanzania and Egypt by the end of this year.

Huawei launches world's slimmest smartphone

June 19, 2013

China's Huawei unveiled its flagship smartphone, the Ascend P6, at its first standalone launch event on Tuesday, underlining its ambitions to compete with Apple and Samsung in the top tier of mobile technology.

The company says the device, at 6.18 mm thick, is the world's slimmest. It has a 5 megapixel front-facing camera, designed for taking "selfies", or pictures of the owner to be shared on social media networks.

The company picked the launch date - 6/18 (June 18) - to tie in with the smartphone's dimensions.

The launch, at an arts venue in North London, takes a cue from Apple and Samsung, both of which have made new product announcements at high profile events for a number of years.

Previously Huawei unveiled its handsets at industry trade shows like Mobile World Congress in Barcelona.

Huawei, which also makes telecom networking gear, is looking to drive sales of its consumer devices, a sector in which it has only had its own brand for about three years.

The company was the fourth-largest maker of smartphones in the first quarter of 2013, trailing LG Electronics and the two dominant brands Apple and Samsung, according to analyst firm Gartner. The top two sold more than 100 million units between them, while LG sold 10 million and Huawei 9 million, most of which were in its native China.

The Ascend P6 uses Huawei's customised version of Google's Android operating system.

Industry analyst Ben Wood at CCS Insight said that at the right price the Ascend P6 would attract buyers who had not considered Huawei before.

"Huawei P6 is darn thin," he tweeted. But he added that the device was not, at this stage, compatible with the high speed, next generation 4G networks, which are being rolled out across the world.

Carolina Milanesi at Gartner said she would have liked to see a more original design instead of something that tries to position the brand as an alternative to Apple by going with a similar rounded metal design.

Overall it shows that Huawei is working towards their goal of becoming a top brand by 2015, she said.

Chinese scientists observe IT-advancing phenomenon
Updated: 2013-04-11 01:41(Xinhua)

Chinadaily.com.cn

BEIJING - Chinese scientists have made the very first experimental observation of a phenomenon known as the quantum anomalous Hall (QAH) effect, a discovery that will help accelerate the IT revolution and in developing low-power-consumption electronics.

Yang Zhenning, winner of a Nobel Prize in Physics, said at a press conference on Wednesday that the research was ground-breaking in the field, rating it as worthy of a Nobel Prize.

QAH effect is one of the most important physical effects that had remained unobserved worldwide, according to academic Xue Qikun, who has led a team working on the subject since 2008.

The discovery, if it is harnessed in the future, will help reduce unnecessary energy consumption stemming from irregular electron collisions, according to Xue.

"The technology may even bring about a supercomputer in the shape of an iPad," predicted Xue.

The QAH effect was predicted to occur in magnetic topological insulators by American scientist Edwin Hall more than 130 years ago. It is a kind of quantum Hall effect realized at zero magnetic field.

The quantum Hall effect describes how a voltage appears at both semiconductor edges when the electrons on a current-carrying semiconductor experience a force while being kept in a magnetic field, Xue explained.

The academic said that although leapfrog development has been made in semiconductor technology, the unsettled problem of thermal dissipation caused by irregular movements of electrons has created a bottleneck for the IT industry's further development.

The research, launched by a team of scientists from Tsinghua University and the Institution of Physics under the Chinese Academy of Science, was conducted on more than 1,000 samples at zero magnetic fields.

However, there remains a long way ahead for the observation to be taken into practical application due to limited research resources at present, Xue added.

Two collider research teams find evidence of new particle Zc(3900)
Jun 18, 2013

Two collider research teams find evidence of new particle Zc(3900)

(Phys.org) —Two research teams working independently at two different particle accelerators have found evidence of what appears to be a four-quark particle that has come to be called Zc(3900). Both teams are made up of a large number of researchers affiliated with institutions from around the world and both have published their findings in separate papers in the journal Physical Review Letters.

The discovery of what appears to be a new particle has come about at the two sites (the Belle and BESIII experiments in Japan and China, respectively) as a result of research into Y(4260), a particle discovered in 2005. Physicists have been intrigued by Y(4260) as it appears to be made of a charmed quark, an anti-charmed quark and an extra gluon (in addition to the gluons holding the quarks together). In studying the decay of Y(4260)—which is found in the debris after smashing electrons and positrons together in their respective accelerators—both research teams noticed a spike of energy of about 3.9 gigaelectronvolts, which, as it turns out, is approximately four times the weight of a proton. That suggested evidence of a particle with four quarks, something that has never been seen before.

After much more study, both teams concluded that what their data was showing them was something both new and real. Initial indications are that Zc(3900) is indeed a previously unknown type of matter—a particle with four quarks. Combined, the research teams have found 460 examples of the Zc(3900) particle giving serious credence to their actual existence. Thus far, the particle appears to have an electric charge and at least one charm and one anti-charm quark. Both teams suspect that it also has an up and anti-down quark as well, giving it its full complement of four quarks.

Both research teams point out that there might be other explanations for their findings—Zc(3900) could simply be a pair of two-quark particles bound together, for example. Another possibility is that it's a pair of two-quark particles that are loosely bound, which would mean they are simply interacting for a very short time span.

More research will be conducted by both teams, and of course other physicists around the globe. Studying how Zc(3900) decays should help determine if what the two teams have found is something truly new, or if it is just already known particles behaving in a novel way.

Chinese Scientists Discover New Method to Increase Recoverable Oil from Wells

Mon, 17 June 2013 21:41

http://oilprice.com

Chinese scientists have already succeeded in recovering a sensational 15% of the residual oil in their test reservoir when they formed a collaboration with the Centre for Integrated Petroleum Research (CIPR) in Bergen, Norway researchers to find out what had actually taken place down in the reservoir.

Oil in reservoirs is confined in tiny pores within rock, often sandstone. In the “old days” of easy oil the natural pressure in a reservoir was so high that the oil flowed upwards when drilling reached the rocks containing the oil.

When the pressure is used up and the petroleum companies abandon an oil well, more than half the reservoir’s oil is usually left behind as too difficult to recover. Now, however, much of the residual oil can be recovered with the help of nanoparticles and a simple law of physics.

Density Gradient and Nanoparticles Used for Oil Recovery.


In the petroleum companies’ arsenal to maintain the pressure within a reservoir the companies have learned to displace the produced oil by injecting water. The water forces out the oil located in areas near the injection point. The actual injection point may be hundreds or even thousands of meters away from the production well.

But eventually water injection loses its effect. Once the oil from all the easily reached pores has been recovered, water begins emerging from the production well instead of oil, at which point the petroleum engineers have few choices other than to shut down the well.

China develops own tech to enrich uranium
Global Times
2013-6-25 0:03:01

China National Nuclear Corporation (CNNC) has announced that it has finally been able to successfully produce enriched uranium for industrial purposes using domestically made technology.

The first batch of the independently produced fuel, made in a facility in Lanzhou, Gansu Province, on Friday, can be used in nuclear power stations nationwide after further processing. The move, widely seen as a great step in the country's nuclear industry, helps industrialize the process of enriching uranium.

"After years of research, China has finally achieved this goal. China has become one of the few countries that own independent uranium enrichment technology and use it for industry. It is a milestone," said Lei Zengguang, chief engineer of CNNC on Monday.

Uranium enrichment technology is critical to a country's nuclear industry, as raw natural uranium contains only 0.7 percent of uranium-235, with the remaining 99.3 percent being uranium-238. Most of China's nuclear power stations need enriched uranium, containing 2 to 5 percent of uranium-235, reported China Central Television (CCTV) Saturday.

"The Lanzhou plant uses self-designed gas centrifuge machines to separate uranium-235 and -238," Lei said, adding that gas centrifuges consume less power compared with other enrichment means, halving the general costs.

"Among all the means of uranium enrichment, gas centrifuges are the most mature. They have already been used in countries such as Russia and the UK," an unnamed nuclear professor with Tsinghua University told the Global Times Monday. "It's a key technology for any country to produce nuclear fuel. That symbolizes the nuclear industrialization level of a country," he said.

"These gas centrifuge machines will be responsible for supplying fuel to all 17 nuclear power stations under operation in China. It can even meet the entire demand by 2020, when the requirement will be five times more than it is now," Zhu Ji, manager of the Lanzhou uranium enrichment plant, was quoted by CNNC's website as saying.

"Independent uranium enrichment is essential for China's nuclear industry. It will definitely help China to complete its nuclear production chain with low costs," the professor told the Global Times Monday.

The Lanzhou plant welcomed its first ever visit by reporters on Friday.

"Citing confidentiality, I cannot provide you with more details on those gas centrifuges," an unnamed employee with CNNC told the Global Times on Monday, adding that the Lanzhou facility was founded in 1958 and had never been open to the public.
