BEIJING puma suede heart satin noir , July 28 (Xinhua) -- China's central bank on Friday continued to pump money into the interbank market via reverse repos to ensure stable liquidity.

The People's Bank of China (PBOC) conducted 100 billion yuan (nearly 15 billion U.S. dollars) of seven-day reverse repos with an interest rate of 2.45 percent, and 40 billion yuan of 14-day reverse repos with an interest rate of 2.6 percent.

Offset by 100 billion yuan of maturing operations, the move resulted in a net injection of 40 billion yuan.

In Friday's interbank market, the overnight Shanghai Interbank Offered Rate, which measures the cost at which banks lend to one another, rose 2.92 basis points to 2.8152 percent.

There was a total of 280 billion yuan of net cash injections for financial institutions from Monday to Friday puma suede heart satin gris , down from 510 billion yuan a week ago.

The PBOC has increasingly relied on open-market operations for liquidity, rather than cuts in interest rates or reserve requirement ratios, to maintain a stable money market.

China set the tone of its monetary policy in 2017 as prudent and neutral, keeping an appropriate liquidity level but avoiding excessive injections.

CHICAGO, Aug. 10 (Xinhua) -- Researchers in materials scienceand mechanical engineering at the University of Michigan (UM) havedeveloped a new technique that can change plastic's molecularstructure to help it cast off heat.

The new technique uses a process that engineers the structure ofthe material itself puma suede heart satin gris pas cher , considering the nature of plastics made oflong chains of molecules that are tightly coiled and tangled like abowl of spaghetti.

It used a chemical process to expand and straighten the moleculechains, giving heat energy a more direct route through thematerial. To accomplish this, the researchers first dissolved atypical polymer, or plastic in water, then added electrolytes tothe solution to raise its pH, making it alkaline.

The individual links in the polymer chain puma suede heart satin gris femme , called monomers, takeon a negative charge, which causes them to repel each other. As themonomers spread apart, they unfurl the chain's tight coils.Finally, water and polymer solution is sprayed onto plates using acommon industrial process called spin casting, which reconstitutesit into a solid plastic film.

The uncoiled molecule chains within the plastic make it easierfor heat to travel through it.

Researchers also found that the process has a secondary benefit:it stiffens the polymer chains and helps them pack together moretightly puma suede heart satin femme pas cher , making them even more thermally conductive.

"Polymer molecules conduct heat by vibrating, and a stiffermolecule chain can vibrate more easily," said Apoorv Shanker, amaterials science and engineering graduate student who has been inthe research team led by UM materials science and engineeringprofessor Jinsang Kim. "Think of a tightly stretched guitar stringcompared to a loosely coiled piece of twine. The guitar string willvibrate when plucked, the twine won't. Polymer molecule chainsbehave in a similar way."

The process is a major departure from previous approaches, whichhave focused on adding metallic or ceramic fillers to plastics puma suede heart satin pas cher , aprocess that is expensive as well as can change the properties ofthe plastic in undesirable ways.

The work has important consequences because of the large numberof polymer applications where temperature is important.

"Researchers have long studied ways to modify the molecularstructure of polymers to engineer their mechanical, optical orelectronic properties, but very few studies have examined moleculardesign approaches to engineer their thermal properties," said UMassociate professor of mechanical engineering Kevin Pipe. "Whileheat flow in materials is often a complex process, even smallimprovements in the thermal conductivities of polymers can have alarge technological impact."

The study has been published in the journal Science Advances.Enditem

MOSCOW, Aug. 11 (Xinhua) -- Growth of two-way trade between China and Russia has been picking up speed puma suede heart reset bleu pas cher , and is most likely to reach the previously set goal of 80 billion U.S. dollars this year, Russian experts have said.

"Considering the seasonality, reaching 80 billion dollars is quite possible, especially if we take into account the fact that metal prices have increased very much in the last month, including in anticipation of a decline in Chinese output and closure of ecologically harmful and surplus production capacities," Alexander Gabuyev puma suede heart reset bleu , head of the Russia in the Asian-Pacific program at the Carnegie Moscow Center, told Xinhua in a recent interview.

According to China's General Administration of Customs, the import and export turnover between Russia and China in January-July 2017 amounted to 46.82 billion dollars, an increase of 21.8 percent year-on-year.

"Given the importance of raw materials in Russian exports, and if oil prices stay at the current level and metal prices remain high, then 80 billion will be achieved by the end of the year puma suede heart reset rose pas cher ," Gabuyev said.

Meanwhile, statistics show that Russia's non-resource exports to China are also growing, which in Gabuyev's opinion should be attributed to the cheap ruble and joint efforts of both governments to eliminate tariff barriers and improve infrastructure in order to promote the trade of food products.
