2. The pattern of cultivating diamonds in the tens of billions of markets has accelerated the formation of a three-point world ( read the full text )
The future market will change from the current “natural diamonds dominate the world†to “very clear natural diamonds, ambiguous diamonds and true nurturing diamondsâ€. The emergence of nurturing diamonds has brought about the reconstruction of the value of diamonds. Natural diamonds and nurturing diamonds are beautiful incarnations, but their functions are different: the former is the essence of nature, high quality and rare, and has certain investment attributes; the latter is the crystallization of human wisdom, is an excellent high-tech material, the main decorative function . “Natural diamonds and nurturing diamonds will form an interdependent pattern. The industry will compete and interact, the boundaries will become clearer, and eventually a dynamic balance will be achieved at some stage.
Consumers in the end market accept and recognize the cultivation of diamonds, which will eventually be a long-term systematic project. Success depends on consumer education and market strategy, and ultimately requires consumers and the market to “take the foot†to vote. It and natural diamonds should not be a game of win-win and lose, misplaced, complementary, and jointly enlarge the market, should be the greatest common denominator of both sides.
Therefore, how to quickly establish a healthy breeding diamond ecosystem will be a long-term problem for every diamond practitioner.

4. In-depth study on how to improve the precision and smoothness of wire cutting processing ( Read the full text )
With the rapid development of molds and precision manufacturing, as a high-precision electric machining machine tool - wire cutting is increasingly favored by the majority of enterprises, it is guided by high melting point metal wire, between the wire and the workpiece Instantaneous high temperature discharge corrosion for processing. Although it does not produce cutting force, if it does not pay attention to the processing technology, there will be defects in machining accuracy and surface quality. Through past operational experience, I have come up with some more effective improvement measures for your reference.

6, Nobel Prize in Chemistry, Mowasang's Synthetic Diamond Light Comedy ( Read the full text )
Shortly after the combustion reaction proved that the diamond was charcoal, the French chemist Guyton de Mouveau said that the diamond was directly converted into graphite in 1799, and the diamond and charcoal were definitely certain. Burning diamonds into smoke and directly turning into graphite are all actions of losing the family, and people can't help but shake their heads. But if it turns out to turn graphite into diamonds, how exciting it is, the ladies on the street can wear diamond rings with diamonds of two pounds. What the scientific historians may not pay much attention to is that the point of graphite into diamond is a more tempting career than the stone. The former's attraction to scientists and the promotion of science are not inferior to the latter.
In order to advance science and gain wealth, many scientists have devoted themselves to the business of graphite into diamonds. In 1880, the British JB Hannay declared that paraffin, bone oil and lithium metal were calcined in steel pipes to obtain diamond particles. This work has been highly praised and sought after by other scientists, but it has been found that the results in Han can not be repeated, and diamonds are not obtained by this method. However, the enthusiasm of scientists will not have the slightest impact, more people are committed to this great cause, and more thinking and methods are being tested one by one in different laboratories.
7. [Depth] How the RMB transforms into “international currency†Game pricing power ( Read the full text )
Without the cross-border RMB capital market that the “banker†can dominate, it will become the real stage for the future RMB exchange rate to find “market equilibriumâ€.
For the financial market and monetary policy regulators, this round of RMB exchange rate decline has long been expected. The central bank sold nearly $600 billion in just one year to intervene in the foreign exchange market. "This is unprecedented in global financial history."
Since the exchange reform, China's financial regulatory authorities have greatly strengthened their control over the liquidity of the offshore market. The “sniper†of offshore arbitrage capital has become increasingly accurate, and the short-sellers who dare to take risks and “be gambling†with the Chinese central bank are decreasing.
On October 25, 2016, the China Foreign Exchange Trading Center announced that the RMB exchange rate was reported at 6.7744, a new six-year low. Less than a month since September 30, the spot exchange rate of the RMB against the US dollar has fallen by more than 1,000 basis points, depreciating more than 1.5%. Some analysts said that the depreciation is mainly guided by the central bank's central price, and the depreciation trend may continue.
The continuous decline of the RMB exchange rate has caused the public, who originally only focused on the stock market and real estate, to begin to fall into unease. The interpretation of various RMB exchange rates on Weibo and WeChat was screened, and the highly professional topics such as currency and exchange rate suddenly entered the public eye.

10. Real black diamonds are coming! Graphene grown on diamonds ( Read more )
Have you ever heard of graphene that we have seen on copper substrates, silicon substrates, and graphene grown on diamonds? The real black diamond is coming! Think about it, is it very exciting!
How to form large-area high-quality graphene on an insulating substrate is still a problem. Therefore, whether it is to explore a new method for preparing graphene, or to find a suitable base material for growing graphene, in order to present the novel physical properties of graphene at room temperature, it is an urgent need to solve the basic research and device application of graphene. The problem.
Diamond is an insulating material with many excellent properties. If graphene can be fabricated on a diamond substrate, it is advantageous to exhibit graphene special mechanical, thermal, electrical and optical properties at room temperature compared to other substrate materials. Performance is an ideal structure for constructing graphene novelty devices. But so far, studies on the direct preparation of graphene on the diamond surface have rarely been reported.
Recently, Prof. Gu Changzhi, Researcher of the Institute of Physics of the Chinese Academy of Sciences/Beijing National Laboratory for Condensed Matter Physics, and Li Wujie, Li Junjie, and the researcher of Xu Quanfang, Quantum Science Simulation Center, Associate Professor Xu Jing of Renmin University of China and Rensselaer Polytechnic of the United States Professor Zhang Shengbai's cooperation, starting with material design, theoretically predicted that the diamond (111) surface can realize the phase transition of the diamond structure to the graphene structure under the induction of B atoms. After that, the experiment verified the single crystal diamond ( 111) The surface can be self-organized to form high quality graphene under B-doping conditions, and the number of layers is controllable.
