|WASHINGTON Wholesale AC Milan FC Jerseys , March 17 (Xinhua) -- A fungus that turns bread moldy could potentially play a big role in producing sustainable electrochemical materials for use in rechargeable batteries, British and Chinese researchers said Thursday.
The researchers reported in the U.S. journal Current Biology that the fungus Neurospora crassa, commonly known as red bread mold, can transform manganese into a mineral composite with favorable electrochemical properties.
"This is the first demonstration of the synthesis of active electrode materials using a fungal biomineralization process," said Geoffrey Gadd of the University of Dundee Wholesale Arsenal FC Jerseys , who led the study.
"(It) illustrates the great potential of these fungal processes as a source of useful biomaterials," said Gadd, also affiliated with Xinjiang Institute of Ecology and Geography of the Chinese Academy of Sciences.
In earlier studies, the researchers showed that fungi could serve as an efficient system for the biomineralization and production of a variety of metal carbonates, including those of toxic metals Wholesale AS Roma FC Jerseys , which can be easily decomposed into metal oxides through thermal treatment.
In the new study, Gadd's team incubated Neurospora crassa in media amended with urea and manganese chloride and then heated the resulting materials to obtain a mixture of carbonized biomass and manganese oxides.
"We were surprised that the prepared biomass-manganese oxide composite performed so well," said Gadd.
In comparison to other reported manganese oxides in lithium-ion batteries, the carbonized fungal biomass-mineral composite "showed an excellent cycling stability and more than 90 percent capacity was retained after 200 cycles," he said.
"This system therefore suggests a novel biotechnological method for the preparation of sustainable electrochemical materials."
Many efforts have been made to improve lithium-ion battery or supercapacitor performance using alternative electrode materials such as carbon nanotubes and other manganese oxides. But few had considered a role for fungi in the manufacturing process.
Gadd said they'll continue to explore the use of fungi in producing various potentially useful metal carbonates. They're also interested in investigating such processes for the biorecovery of valuable or scarce metal elements in other chemical forms.
The study was funded by the China Scholarship Council and the 1000 Talents Plan with the Xinjiang Institute of Ecology and Geography.
WASHINGTON Wholesale Atletico Madrid FC Jerseys , Sept. 25 (Xinhua) -- A man was arrested Monday on charges of killing a Chinese woman near the southeastern U.S. city of Atlanta, capital of the state of Georgia, local police said.
The Chinese consulate general in Houston confirmed the arrest, but said no further information was immediately available.
Local police identified the suspect as 24-year-old Brian Marsh Semrinec. The victim, 28-year-old Chinese woman surnamed Li and alumna of the Georgia Institute of Technology Wholesale Chelsea FC Jerseys , was found dead in her apartment near Atlanta on Sept. 18.
The incident has heightened the Chinese community's concerns about the safety of Chinese studying or living in the United States, especially after a high-profile case involving the disappearance of a Chinese female three months ago.
Zhang Yingying, a visiting scholar at the University of Illinois at Urbana-Champaign, was reported missing on June 9 after entering a car. The suspect, Brendt Christensen Wholesale FC Barcelona Jerseys , was arrested on June 30. Zhang has not yet been found and is believed to be dead.
HONG KONG, Sept. 22 (Xinhua) -- Hong Kong Exchanges and Clearing Limited (HKEX) on Friday published consultation papers on delisting and other rule amendments to improve market quality.
The deadline for responses is Nov. 24.
Under the Main Board Listing Rules, a separate delisting criterion should be added to allow the exchange to delist an issuer after its continuous suspension for a prescribed period, proposed to be 12, 18 or 24 months Wholesale FC Bayern Munich Jerseys , according to the consultation paper.
Under the Growth Enterprise Market (GEM) Listing Rules, a separate delisting criterion should be added to allow the exchange to delist an issuer after its continuous suspension for a prescribed period, proposed to be six or 12 months, it said.
"After adopting a more robust delisting policy to address concerns about a number of long suspended issuers, we are proposing changes to the delisting framework to facilitate efficient and orderly exits of poor quality issuers and provide certainty to the market on the delisting process Wholesale FC Borussia Dortmund Jerseys , bringing our practice more in line with other major markets," said David Graham, HKEX's Chief Regulatory Officer and Head of Listing.
HKEX proposes to introduce targeted measures in the rules to address potential abuses related to large scale deeply discounted capital raising activities.
The consultation paper also contains proposals to address specific issues concerning other capital raising and share issuance transactions.

The explosion happened at an outlet of Chicago Pizza Co., some 100 meters from the Subway Station Motomachi in central Kobe.
The employees of the shop were draining a ga.
