U.S. Official: 'No Limits' to Investigating Firms Trading Tungsten Trioxide Violating North Korea Sanctions

The United States is pursuing more investigations into Chinese firms with North Korea  sanctions against a Chinese trading company suspected of supporting North Korea's nuclear weapons development.

Daniel Fried, the U.S. State Department's coordinator for sanctions policy, said the investigations are underway during a U.S. Senate hearing on East Asia and the Pacific, Yonhap reported.

"We're investigating. The Treasury and State are investigating firms around the world," Fried said. "There are no limits and there is no administration red line of exempt countries or companies. We go where the evidence takes us." Fried said it is very effective to convey to Chinese banks and companies that trade with North Korean firms under sanctions is dangerous and not worth the trouble, according to the report.

The State Department official also said sanctions measures are not mere slogans. "Our actions on Monday indicate that Chinese companies are not off limits. That news will spread around the Chinese community. We can also use various means to get the word out to Chinese businesses and banks that we are serious," he said.

On Monday the U.S. Treasury announced Hongxiang Industrial, suspected of sending banned material to North Korea, had been placed under unilateral sanctions. Washington is taking action against the company's chief executive Ma Xiaohong, a 44-year-old businesswoman who founded the company in 2000, and three other members of her organization.

Hongxiang Industrial is believed to have exported aluminum oxide, ammonium paratungstate, and tungsten trioxide to North Korea, dual-use items that could have been placed into military use. Aluminum oxide can be used in developing the centrifuges used in uranium enrichment.

Fried also said investigations are underway into Air Koryo, North Korea's commercial airliner.

USA Imposed Sanctions on Chinese Firm Having Trade of Tungsten Trioxide with North Korea to Aid Nuclear Weapons

The Treasury Department and Justice Department took the measures on Monday, saying that the company and the individuals conspired to aid North Korea’s nuclear weapons program in violation of US economic sanctions.

The measures were taken against 44-year-old Ma Xiaohong and her conglomerate based in China's frontier city of Dandong for money laundering and evading sanctions.

The Treasury Department accused the firm, Dandong Hongxiang, and a host of officials of making up a "key illicit network supporting North Korea's weapons proliferation."

Adam J. Szubin, acting undersecretary for terrorism and financial intelligence at the Treasury Department, said, “Treasury will take forceful action to pressure North Korea’s proliferation network and to protect the US financial system from abuse.”

Dandong Hongxiang had over $530 million worth of trade with North Korea from 2011 to 2015, according to a report by the Asian Institute for Policy Studies in Seoul and C4ADS in Washington. The amount could have been enough to help North Korea fund its uranium enrichment facilities, and to design, make, and test its nuclear weapons, the report said.

Among the items traded, there were aluminum ingots, aluminum oxide, ammonium paratungstate and tungsten trioxide as well as materials used in nuclear enrichment centrifuges and missile design.

Tungsten trioxide can be used in making more aerodynamically stable missiles, while aluminum oxide is used to resist corrosion in gas centrifuges during uranium enrichment, according to Asan. It said those could qualify as "potential military and nuclear dual use products" under U.S. Department of Commerce restrictions.

The three other individuals who were targeted include Zhou Jianshu, Hong Jinhua and Luo Chuanxu, who can no longer do business with American individuals or companies. The department also sought to seize 25 bank accounts controlled by Dandong Hongxiang, because it said they "represent property involved in money laundering."

The move came after Pyongyang conducted its fifth nuclear test on September 9. It also tested a submarine-launched ballistic missile in August. South Korean officials say the North is physically ready to conduct its sixth nuclear test.

Pyongyang says it will continue to develop nuclear weapons as a “deterrence” measure against America’s military aggression.

Tungsten Carbide Inserts: Leaping Development of Manufacturing Field

Tungsten carbide is a very high hardness materials, cutting tools are mainly used in metal cutting has been widely used. In the machinery industry, mentioned alloy steel or tungsten carbide generally refers to such materials. Carbide cutting tools can be harvested many advantages. Compared to high speed steel cutting tools, in most cases, the use of carbide cutting tools can be harvested only workpiece surface quality is better, but also to obtain higher processing speeds; Carbide Tool can withstand higher cutting heat, which is that it can achieve a higher metal removal rate of the main reasons. When the workpiece machining high-alloy steel or stainless steel such easy processing, or in mass production and capacity expansion of the occasion, a case such as high-speed steel cutting tool wear easily and quickly, using conventional carbide tools can make cutting performance better.

Tungsten carbide cutting tools for metal cutting industrialization began in the nineteen thirties. Since then, it has evolved into carbide by far the most common tool materials. The relatively small size of carbide cutting tools are often made of a whole; only non-solid carbide cutting tools with carbide in the cutting area. Early non-carbide solid carbide tools tend to be welded to the cutter body. To the 1940s, carbide cutting tools manufacturers began producing holding interchangeable machine folder blade cutter, and benefit. Compared to the earlier welding tool, this brain-hole wide open to technological innovation and the use of mechanical clamping structure makes the tool more strength, which has now been recognized as a landmark invention, not only in the field of tool manufacturing further comprising bringing advanced and efficient process for the entire metalworking industry.

The considerable progress in the field of manufacturing opened up vast room for improvement, and immediately increase the carrying capacity of the tool, the tool has the ability to make rapid removal of metal. Replace the blade becomes more simple and cost reductions made to protect the economy, but also makes it possible to separately manufacture cutting module and the cutter body except for the blade failure due to wear or breakage failure. Replace the blades often need to consider the shape, quickly replace the failed cutting edge in several ways, in addition to the blade along the central axis indexing, there are also cases reversed blade front and back. Today, the most recognized industry wide dissemination of "indexable" the title, once also known as: the disposable tip, replaceable blade, replaceable blade.

Tungsten carbide indexable insert production technology based on powder metallurgy technology, the production process is as follows: Preparation of carbide mixture, pressing, sintering, sintering treatment step and coating. Despite decades or more basic process remains the same, but at the same time from the progress of science and technology but then blade manufacturing had a significant impact.

Until the 1980s coated carbide grade has not yet appeared. At that time, such that carbide can be common to the processing of different engineering materials, tool manufacturers by adding different additives (such as a hard phase or a metal additive) to the preparation of different carbide grades. Coating technology adoption has greatly promoted the development of the global machinery industry; the vast majority of today are coated carbide grades. This new technology also brings additional benefits, so some special grades can be processed a certain class of materials to be processed. You do not need to add many kinds of cemented carbide substrate additives; This reduces the cemented carbide substrate grades, production process control more stable.

PVD coating in the late 1980s is introduced into the carbide production. PVD coating because at the nanoscale coating areas to overcome the manufacturing of many problems to achieve a breakthrough in the development. PVD coating thus providing a new level of higher wear resistance nano-coating. Compared to conventional PVD coating manner coating as shown by a maximum of 50 nm (nanometer) coating composite, it has been shown to greatly improve the binding strength of the coating.

Tungsten carbide blade production progress technologies from several areas of development. More cutting-edge technology of pressing, sintering technology, coating technology and post-coating technology, more diverse surface treatments can be carried out on the cutting edge of the blade more optimized manufacturing process together make indexable inserts can provide modern metal processing industry to provide more suitable to meet their needs efficient processing solutions.

Latest Research for Non-volatile Memory Device Uses WO3

Not long ago, James M. Tour of Rice University group by anodic treatment to obtain a flexible nano-porous (NP) WO3-xRRAM at room temperature. The Task Force found that the flexibility of NP WO3-x RRAM exhibits bipolar switching property and high Ion/Ioff ratio (approximately 105); at the same time, this device has a stable holding time (more than 5×105s) and excellent pole uniformity between the elements; besides, in the conditions of flat or the maximum bending, the degrees of resistance to bending are more than 103 cycles. Research indicates, the flexible resistive memory (RRAM) has a great prospect in the future non-volatile memory device, this time the discovery of ACS nano flexible WO3-x non-volatile memory device becomes the latest research of tungsten trioxide (WO3) in non-volatile memory device, and expanding the application fields of WO3.
 
WO3 in nonvolatile memory device
In addition, in 2015, Professor Xie Yi, USTC has made new progress on the high-performance of flexible non-volatile  memory device, synthesized excellent storage property based on WO3•H2O thin nano-sheets and assembled into Cu/WO3•H2O/ITO-PET flexible non-volatile  memory device. Further, the group also proposed novel mechanism of resistance change memory which is contributing to the further research and development of mechanism of resistive non-volatile memory.
 
Further reading: Non-volatile memory, nonvolatile memory, NVM or non-volatile storage is a type of computer memory that can retrieve stored information even after having been power cycled (turned off and back on). Examples of non-volatile memory include read-only memory, flash memory, ferroelectric RAM (F-RAM), most types of magnetic computer storage devices (e.g. hard disk drives, floppy disks, and magnetic tape), optical discs, and early computer storage methods such as paper tape and punched cards. Non-volatile memory is typically used for the task of secondary storage, or long-term persistent storage. The most widely used form of primary storage today is a volatile form of random access memory (RAM), which means that when the computer is shut down, anything contained in RAM is lost. However, most forms of non-volatile memory have limitations that make them unsuitable for use as primary storage. Typically, non-volatile memory costs more, provides lower performance, or has worse write endurance than volatile random access memory. Non-volatile data storage can be categorized in electrically addressed systems (read-only memory) and mechanically addressed systems (hard disks, optical disc, magnetic tape, holographic memory, and such). Electrically addressed systems are expensive, but fast, whereas mechanically addressed systems have a low price per bit, but are slow. Non-volatile memory may one day eliminate the need for comparatively slow forms of secondary storage systems, which include hard disks.
