Dalian Coherent Light Source Produces Laser Output for the First Time
Oct 10, 2016

The installation process of the main body of the comprehensive experimental device based on tunable Extreme Ultraviolet (EUV) coherent light source - Dalian Coherent Light Source (DCLS) has completed on September 24, 2016.

After strictly system installation project acceptance of relevant experts, the project experts began the free electron laser (FEL) amplifier light debugging at 21:30, the whole debugging process went very smoothly.

At 22:50, high-quality pulsed electron beams with more than 300 Mev energy passed through all the elements of the free electron laser amplifier, the first beam of ultraviolet light was emitted through the 18-meter wave oscillator array.

DCLS is the only user FEL facility operating exclusively in the EUV wavelength region in the world, and it is also the first free electronic laser large scientific user device of our country. After debugging, this device will produce the world's brightest EUV beam.

Each laser pulse of the light source can emit more than 10 trillion photons with wavelengths continuously adjustable from 50nm to 150nm, with complete coherence. This light source can be widely applied in chemical, physical, biological, energy, materials, environmental and other important scientific fields.

SMIC set to invest US$10b in wafer plant

By Zhu Shenshen | October 14, 2016, Friday

SEMICONDUCTOR Manufacturing International Corp will invest US$10 billion in a new 12-inch wafer plant in Shanghai, the most advanced chip manufacturing technology in the integrated circuit industry, the company said yesterday.

The entire project, including the 67.5 billion yuan (US$10 billion) new 12-inch wafer line and related industries, will cost more than 100 billion yuan, said officials of SMIC, the Ministry of Industry and Information Technology and Shanghai city government attending the ground-breaking ceremony yesterday in the Pudong New Area.

The new wafer plant, with a monthly capacity of 70,000 units when fully operated, is expected to meet surging domestic demand in the integrated circuit market, the Chinese mainland’s biggest made-to-order chip maker said.

The wafer plant will produce highly advanced chips that are widely used in smartphones, TVs, automotives and other devices.

China aims to invest US$100 billion in its semiconductor industry over the next few years, research firm Bain said in a previous report.

By 2020, 55 percent of the world’s memory, logic and analog chips are destined to flow to or through China. The country only produces about 15 percent of these chips, up from about 10 percent a few years ago. But the higher production is still not sufficient to narrow the gap between supply and demand, Bain said.

Intel makes 14nm chips for Spreadtrum

by NICK FARRELL on 04 OCTOBER 2016



Thinks Samsung will be interested

Chipzilla has announced that it is making 14nm application processors for Spreadtrum and the pair might have Samsung as a client.

Spreadtrum thinks its Intel chips will just be what Samsung wants for its mid-range smartphone series for 2017.

According to Digitimes, Spreadtrum is also contracting TSMC to build chips using the foundry's 16nm process technology. LG has signed up Intel to make its 10nm process technology for its ARM-based mobile SoCs. LGE is also TSMC's 16nm and 28nm clients.

Intel only has a workforce of 2,000 people, but it is targeting fabless customers based mainly in China, South Korea, Japan and other countries of Asia. In addition, a team of Intel employees stationed in Shanghai is working with local Chinese manufacturers.

@Bussard Ramjet Spreadtrum going places...Indian equivalent???

Chinese scientists achieve high-power quantum computing
(China Daily) October 15, 2016

If early mechanical computers were never introduced to expand people's computing ability, the invention of the atomic bomb would have gone out the window, and human history would have been rewritten.

This highlights the significance of computer simulation in scientists' exploration of the physical world, which also explains their strong motivation in continuously pursuing higher computing power.

In a recent case, Chinese scientists managed to tremendously enhance such power — they succeeded in performing quantum simulation with atoms in extraordinarily cold conditions.

In physics, quantum refers to the minimum amount of any physical matter. Like the rotation and revolution of the Earth, quantum spins and moves at the same time, and sometimes can be twisting together, which is called spin-orbit coupling — the interplay of a quantum's 'rotation' and 'revolution'.

"The most exciting discovering in physical theories exists in the particles with spin-orbit coupling effect," said Liu Xiongjun, a professor of physics from the Peking University.

According to Liu, spin-orbit coupling is the key to understanding some most significant discoveries in recent years, such as the topological superconductivity and the Quantum Spin Hall effect, in the development of new energy and new materials.

However, it is virtually impossible to conduct precise studies on such quantum effect in realistic experiment, given the extremely complex environment required.

"That is where computers take better place. We can use a computer to simulate the process and observe the physical properties of different particles," Liu said.

Nonetheless, such simulation requires a computation capacity far beyond that of any conventional computers. So scientists from the University of Science and Technology of China and Peking University proposed and built a two-dimensional spin-orbit coupling system to simulate the process directly, without any computation.

They first held atoms in position by cooling them to extraordinarily low temperature, and then used laser beams to make them move in a way that caused spin and movement to be twisted together on a plane.

This achievement was published in the prestigious journal Science on October 7.

"The two-dimensional spin-orbit coupling system gives us a new tool to look into the laws of physical world. I believe that major discoveries could be made from the system within five years," said Pan Jianwei, a top physicist from the University of Science and Technology of China and an author of the latest paper.

"Now the whole world's physicists are racing against each other to develop a quantum computer. Although a general-purpose quantum computer may be the story two or three decades later, now we can already use quantum simulating technology to serve some special purpose, or mimicking some quantum matters that even beyond our present knowledge," Pan said.

Xinhua Insight: New meteorite strewn field gives clue of largest meteor shower on Earth
Source: Xinhua 2016-10-13 17:27:41

NANJING, Oct. 13 (Xinhua) -- Chinese scientists announced Thursday they have looked into three giant meteorite irons to ascertain the world's longest meteorite-strewn field in Altay, Xinjiang Uygur Autonomous Region.

Scientists with the Purple Mountain Observatory in Nanjing, capital of the eastern province of Jiangsu, said Thursday that the meteorites were all from the same parent asteroid, as their chemical elements are identical.

The earliest dated discovery of the extraterrestrial stones was in 1898, when herdsmen in the Gobi Desert found a 28-tonne silvery stone, which was in the shape of a camel. The Meteoritic Society later named it Armanty, and confirmed it to be the world's fourth-largest meteorite.

Over 100 years later, a second one was found. It weighed 430 kg and was named Ulasitai.

It was not until 2011, when a third one -- Wuxilike -- weighing 5 tonnes was found, that scientists began to notice that the three meteorite were in a line, although across a distance of 425 km.

"They are on the same axis from southeast to northwest, which piqued our interest," said Xu Weibiao, meteorite curator with the observatory under the Chinese Academy of Sciences (CAS).

Xu, one of the chief scientists with the mineralogical research arm of the meteorites, said the meteorites were composed of the same chemical components and microelements.

Several smaller meteorites have also been found in the field, all with the same chemical composition as the larger rocks.

"This suggests that the meteorites were all from the same parent asteroid before it separated as it entered the Earth' atmosphere," said Xu.

HOW BIG WAS THE METEOR SHOWER?

An ordinary meteor shower can scatter meteorites across dozens of kilometers.

Before the finding in Altay, the world's largest meteorite strewn field was Gibeon, with a long axis of 275 km.

Judging by the 425-km strewn length of the Altay field, its meteor shower is likely the largest on the Earth.

However, there is no historical documentation on the incident. Scientists speculate it might have happened prehistorically.

"A meteor shower of such a scale must have had a great impact on the Earth. If it happened after humans walked the earth, we often find cave painting depicting the incident in the area," said Xu.

He said the team has used isotopic dating to determine when the meteor shower occurred.

An average of 20,000 meteorites fall to the Earth every year. Scientists use extraterrestrial stones to determine information about the universe and life signs in space through chemical classification.

For example, scientists previously discovered evidence of magma activity on Mars some 200 million years ago after sampling a meteorite.

In 2017, China will launch the Chang'e-5 lunar probe, which will collect samples from the moon.

"For the moon sample research, the observatory will use more advanced analytical equipment, which will greatly assist our petrological and mineralogical research," Xu said.

According to you then, any person who doesn't blindly parrot Chinese line, is a China hater?

According to you then, any person who doesn't blindly parrot Chinese line, is a China hater?

I can make a clear distinguish between who is making a fact-based discussion, and who is a troller and China-hater, but try to pretend to be objective.

Your typical behavior is:
- if a technology originally invented by Germany or US years before, and we Chinese made it localized later, you will say: this is nothing new, US or Germany already made the technology happens. Fine, very objective comment x1

- if it is a technology invented by us, you will say this technology has few real applications yet, so it is a waste of money to invest on this. Fine, very objective comment x2

- if we invented a technology and start to put it to real use, you will say it requires a huge investment and makes no economical sense. Fine, very objective comment x3

- but if we don't make anything on scientific research, will you stop your bulxxxit comment? No! You will say: China is lagging behind countries A, B, C, D to Z for this, this , this, and this.

Continue your act. This is a public forum that every one has the right to make opinions. But to any China haters, the more time they spend on the China & Fast East section to read all the China-related news, the more desperate they will be.

I don't want to be off topic too much. This thread: China Science & Technology News and Discussion, is the most valuable thread on this section. So I don't want to ruin it.

'Shadow method' reveals locomotion secrets of water striders
A 'shadow technique' to measure forces acting upon the legs of water-walking arthropods was developed by researchers in China to discern the locomotion principles behind water striders, which may help design advanced biomimetic robotics in the future

American Institute of Physics

WASHINGTON, D.C., October 17, 2016 -- While walking beside the creek in the Beijing Botany Garden one autumn, Yu Tian, a professor of mechanical engineering at Tsinghua University in China, noticed the beautiful shadows cast by water striders on the bottom of a shallow creek. If you've spent any time in or around water you've likely seen these water insects zipping along -- they appear to walk or glide swiftly on the surface of still water.


'Shadow method' reveals locomotion secrets of water striders | EurekAlert! Science News

Journal Reference:

Three-dimensional topographies of water surface dimples formed by superhydrophobic water strider legs, Appl. Phys. Lett. (2016), DOI: 10.1063/1.4964788

Abstract

A water strider has a remarkable capability to stand and walk freely on water. Supporting forces of a water strider and a bionic robot have been calculated from the side view of pressed depth of legs to reconstruct the water surface dimples. However, in situ measurements of the multiple leg forces and significantly small leg/water contact dimples have not been realized yet. In this study, a shadow method was proposed to reconstruct the in situ three-dimensional topographies of leg/water contact dimples and their corresponding supporting forces. Results indicated that the supporting forces were affected by the depth, width, and length of the dimple, and that the maximum dimple depth was not proportional to the supporting forces. The shadow method also has advantages in disclosing tiny supporting force of legs in their subtle actions. These results are helpful for understanding the locomotion principles of water-walking insects and the design of biomimetic aquatic devices.
