China is blocking development in South China Sea through coercive means: Pompeo

Posted on by

first_imgWashington: The US has accused China of blocking the ASEAN members accessing more than USD 2.5 trillion in recoverable energy reserves in the South China Sea by illegal construction activities. China claims almost all of the South China Sea. Vietnam, Philippines, Malaysia, Brunei and Taiwan have counter claims over the area. “China’s illegal island-building in international waterways is not simply a security matter. By blocking development in the South China Sea through coercive means, China prevents the ASEAN members from accessing more than USD 2.5 trillion in recoverable energy reserves,” Pompeo said in his address at CERAWeek in Houston Tuesday night. To contrast, the US Government promotes energy security for those Southeast Asian nations, he said in his address to one of the largest gathering of global energy leaders. “We want countries in the region to have access to their own energy. We want to help them. We want to create partnerships. We want transparent transactions, not debt traps. We explore responsibly,” he said. But, China does not play by that same set of rules, he alleged. “Its values are simply different. You see that in places as diverse as Africa, where they often ship in their own labour, creating jobs for Chinese workers rather than for those in the local economy,” he said. “It’s using the debt trap which I referred to just a moment ago to put these countries in a place where it is not a commercial transaction, it’s a political transaction designed to bring harm and political influence in the country in which they’re operating,” Pompeo said. “And we all know the story in Russia,” he said. It invaded Ukraine to gain access to oil and gas reserves. It in turn deprived Ukraine of the possibility of developing those resources for itself and using its pipelines and its networks to bring energy to its own people. Rather, it uses those pipelines to put pressure political pressure on the people of Ukraine, he alleged.last_img read more

SC allows Karti Chidambaram to travel abroad in May

Posted on by

first_imgNew Delhi: The Supreme Court Tuesday allowed Karti Chidambaram, who is facing criminal cases being probed by the ED and CBI, to travel to the US, Germany and Spain this month. A bench comprising Chief Justice Ranjan Gogoi and Justices Deepak Gupta and Sanjiv Khanna said this nod to travel abroad was subject to compliance of conditions imposed earlier. The apex court had in January granted Karti, son of Congress leader P Chidambaram, permission to travel abroad after depositing Rs 10 crore with the secretary general of the Supreme Court. The top court had also asked him to file an undertaking that he would return and cooperate with the investigation. Karti is facing criminal cases which are being probed by the Enforcement Directorate and the CBI. One of the cases relates to the Foreign Investment Promotion Board clearance to INX Media for receiving foreign funds of Rs 305 crore when his father was the finance minister.last_img read more

(i) and (j) compare X-ray diffraction patterns and Raman spectroscopy of the materials in (a-d). Credit: Park, et al. ©2014 American Chemical Society Journal information: Nano Letters The research groups of Professor Junk-Ki Park and Professor Hee-Tak Kim from Korea Advanced Institute of Science and Technology (KAIST) and Professor Yong-Min Lee’s research group from Hanbat National University, all in Daejeon, South Korea, have published their paper on the new fabrication method in a recent issue of Nano Letters.As the researchers explain, current methods to fabricate high-quality graphene fall into two categories: mechanical approaches and chemical approaches. While mechanical cleavage provides high-quality graphene, its low yield makes it insufficient for large-scale production. Chemical approaches, on the other hand, can produce bulk quantities but can involve imperfections. The new method differs from both of these types of methods and involves a few key steps. First the researchers filled a Pyrex tube with graphite powder, and then placed the open-ended tube inside a slightly larger tube. Then they added potassium to the bottom gap between the two tubes, sealed the tubes, and heated them. The heat causes the molten potassium to move inside the micropores between the graphite powders, so that the potassium molecules become intercalated into the graphite interlayers. The resulting potassium graphite compounds were then placed in a pyridine solution, which causes the layers to expand away from each other to form graphene nanosheets that could later be cooled and exfoliated one layer at a time. The researchers performed many sets of experiments in which they varied factors such as the temperatures and the type of solution, which are critical to control the quality and size of the df-G. They found that, by controlling the temperature of the exfoliation step, the size of the df-G can be varied between 0.25 to 14.0 µm2. The researchers demonstrated that wrapping a large-sized negatively charged sheet of df-G around a positively charged piece of Co3O4 creates an anode with several impressive characteristics. Most significantly is its high capacity after many cycles (1050 mAh/g at 500 mA/g and 900 mAh/g at 1000 mAh/g even after 200 cycles). To the best of the researchers’ knowledge, this reversible capacity is the highest among all Co3O4 electrodes ever reported. The researchers explain that the large-sized df-G, with its perfect crystallinity, improves the anode performance because when a single graphene sheet is wrapped around a bundle of Co3O4 particles, the Co3O4 particles are prevented from becoming pulverized and then electrically detaching from the anode, which would otherwise occur. Because of this protective effect, the anode’s capacity is preserved even after 200 cycles, whereas anodes with an imperfect graphene layer rapidly decrease with cycling. The large size of the graphene plays a key role in the performance because a larger size provides a higher cycling stability of the nanosized anode materials by improving their mechanical integrity.With these advantages, the researchers expect the df-G to bring significant advances of composite electrodes for a variety of electrochemical system, including batteries, fuel cells, and capacitors.

DOI: 10.1021/nl500993q Researchers developing cheap, better-performing lithium-ion batteries Explore furthercenter_img (Phys.org) —Graphene has already been demonstrated to be useful in Li-ion batteries, despite the fact that the graphene used often contains defects. Large-scale fabrication of graphene that is chemically pure, structurally uniform, and size-tunable for battery applications has so far remained elusive. Now in a new study, scientists have developed a method to fabricate defect-free graphene (df-G) without any trace of structural damage.

Physicists observe magnetic devils staircase

DOI: 10.1103/PhysRevLett.114.236403 Also at arXiv:1412.7945 [cond-mat.str-el] Explore further Citation: Physicists observe magnetic ‘devil’s staircase’ (2015, June 24) retrieved 18 August 2019 from https://phys.org/news/2015-06-physicists-magnetic-devil-staircase.html Devil’s staircase behavior emerges in the magnetic structure of a cobalt oxide material. Three magnetic phases are shown here, where the arrows represent the different spin configurations that define each phase. These phases have nearly degenerate magnetic energies, so they all coexist as stable phases, but can be easily altered by external modifications such as doping. Credit: T. Matsuda, et al. ©2015 American Physical Society Anomalous spin ordering revealed by brilliant synchrotron soft X-rays Now in a new paper published in Physical Review Letters, researchers led by Hiroki Wadati, an associate professor at the University of Tokyo, have observed devil’s staircase behavior in a certain magnetic material: the cobalt oxide SrCo6O11. By analyzing the microscopic behavior of this material, the researchers found that it contains a large number of magnetic structures that have nearly “degenerate,” or equal, magnetic energies. The coexistence of these many nearly degenerate magnetic structures gives rise to the devil’s staircase behavior, which has the appearance of many (in principle, an infinite number of) proportional step-like structures.Although the devil’s staircase behavior emerges from microscopic effects, the behavior is also reflected in the material’s macroscopic properties. One of the most intriguing properties is the material’s giant magnetoresistance, which means that an applied magnetic field changes the material’s electrical resistance. This property could have implications for designing artificial materials with novel functionalities.To uncover these microscale magnetic properties of the cobalt oxide, the researchers used a technique called soft X-ray scattering (RSXS), which involves bombarding a material with X-rays and measuring the energy and momentum of the scattered X-rays. As a relatively recent development, RSXS has proven to be a powerful tool for investigating the ordered structures in solid materials. For one of the first times ever, the researchers here used RSXS with magnetic fields of several Tesla. The technique enabled the researchers to discover several microscale magnetic structures that escaped detection in earlier experiments. The scientists attribute the material’s unusually large number of nearly degenerate magnetic phases—and the resulting devil’s staircase behavior—to competition between the magnetic phases. This competition results in magnetic frustration, as no single phase is strong enough to dominate the others. The results show that strong magnetic frustration is a key ingredient for giving the material its giant magnetoresistance and also makes the material highly sensitive to very low chemical doping. To demonstrate this sensitivity, the researchers showed that substituting just 3% of the strontium atoms with barium atoms destroys almost all of the material’s degenerate magnetic phases, which greatly changes its overall magnetic properties. Because the material’s properties are easily tunable in this way, the scientists hope that this research may offer a path toward engineering and controlling the material’s magnetic and electrical properties for various technological applications. “In future resonant soft X-ray diffraction studies, one can expect to find similar devil’s staircase behavior in other materials,” Wadati told Phys.org. “The devil’s staircase behavior may lead to the development of novel types of spintronics materials, which can use discrete levels of electrical resistivity.”center_img Journal information: Physical Review Letters © 2015 Phys.org (Phys.org)—Many hiking trails feature a “devil’s staircase”—a set of steps that are often steep and difficult to climb. The devil’s staircase is also the name of a mathematical function whose graph exhibits a jagged step-like organization reminiscent of a real staircase, although in a highly ordered fractal pattern. Devil’s staircase behavior emerges in a variety of areas, such as in crystals, phase transitions, and statistical physics. This document is subject to copyright.
