SAN FRANCISCO Cheap Nike Vapormax 2018 Women's Purple , Aug. 12 (Xinhua) -- Electrical engineers at Stanford University have identified two semiconductors, hafnium diselenide and zirconium diselenide, that share or exceed some of silicon's desirable traits, starting with the fact that all three materials can "rust," which insulates its tiny circuitry.


Described in a paper published Friday in the journal Science Advances, the new materials can be shrunk to functional circuits just three atoms thick and they require less energy than silicon circuits.


Among several qualities that have led silicon to become the bedrock of electronics Cheap Men's Nike Vapormax CS Triple Black , one is that it is blessed with a very good "native" insulator, silicon dioxide or, in plain English, silicon rust.


Exposing silicon to oxygen during manufacturing gives chip-makers an easy way to isolate their circuitry. Other semiconductors do not "rust" into good insulators when exposed to oxygen, so they must be layered with additional insulators, a step that introduces engineering challenges.


Both of the diselenides the Stanford researchers tested formed this elusive Cheap Men's Nike VaporMax Laceless Pure Platinum White , yet high-quality insulating rust layer when exposed to oxygen. Both ultrathin semiconductors form what are called "high-K" insulators, which enable lower power operation than is possible with silicon and its silicon oxide insulator.


In addition, as they started shrinking the diselenides to atomic thinness, the researchers realized that the semiconductors share another of silicon's secret advantages: the energy needed to switch transistors on, a critical step in computing called the band gap, is in a just-right range.


While both materials were in the same optimal range as silicon Cheap Men's Nike VaporMax Black Anthracite , any other semiconductors that need too low energy to switch transistors on could result in leaky and unreliable circuits, and others that need too high could lead to circuits taking too much energy to operate and becoming inefficient.


The combination of thinner circuits and desirable high-K insulation means that the two ultrathin semiconductors could be made into transistors 10 times smaller than anything possible with silicon today.


Although still experimental, the researchers believe the materials could be a step toward the kinds of thinner, more energy-efficient chips demanded by devices of the future.


Next, they need to refine the electrical contacts between transistors on their ultrathin diselenide circuits, work to better control the oxidized insulators to ensure they remain as thin and stable Cheap Nike Presto , then begin to integrate with other materials and to scale up to working wafers, complex circuits and eventually complete systems.


As there is much work ahead, the researchers acknowledge that silicon will not go away for quite a long time.

LOS ANGELES, Jan. 14 (Xinhua) -- Former NBA star Dennis Rodman was arrested in Newport Beach, a city 30 kilometers east of Los Angeles downtown and charged with driving under the influence (DUI) Cheap Nike Shox , the local police said Sunday.


Rachel Johnson, Area 3 Commander in the Patrol Division of Newport Beach Police Department, was quoted by local media as saying that the 56-year-old Hall of Famer was pulled of for a traffic violation then failed a breathalyzer test given on scene.


Rodman was arrested and spent the night in jail before he was released early Sunday.


Rodman, who has a history of alcohol abuse, was required to attend an alcohol program in July 2000 after he pleaded guilty to DUI and was also checked into a rehabilitation facility in January 2014.


last February, Rodman was sentenced to three years of probation for misdemeanor charges stemming from going the wrong way onto highway in Santa Ana of Southern California.


In this case Cheap Air Max 90 , Rodman drove an SUV onto an exit ramp for a carpool lane for Interstate 5 highway, causing another driver who had to swerve to avoid hitting him to crash into a center divider.


Rodman is an American retired professional basketball player, who played for the Detroit Pistons, San Antonio Spurs, Chicago Bulls, Los Angeles Lakers Cheap Air Max 270 , and Dallas Mavericks of NBA. The five-time NBA championship winner was nicknamed ""The Worm"" and was known for his fierce defensive and rebounding abilities.


Apart from basketball, Rodman also attracted international attention for his visits to Democratic People's Republic of Korea (DPRK) and his friendly relationship with the DPRK top leader Kim Jong-un.

FRANKFURT, Sept. 14 (Xinhua) -- Even as several countries move towards ending the era of fossil fuel-powered vehicles, two German auto-suppliers Bosch and Continental defended the future of combustion engines Thursday.


While reaffirming their electrification strategy at the Frankfurt Motor Show (IAA) 2017, technology company Continental emphasized the importance of innovation and inventiveness over technological specifications and quotas.


"We have some tough targets for CO2 as fleet average. However, we are not quite convinced to push the market in a certain direction through regulation Cheap Air Max 97 Plus ," Oliver Maiwald, senior vice president of Technology & Innovation with Continental, told Xinhua. However, Continental also believes the future of mobility is electrification.


Bosch said combustion engines can be made CO2 neutral, and synthetic fuels can be designed to burn practically soot-free.


Volkmar Denner, chairman of the Bosch board of management Cheap Air Max 97 Ultra' 17 , said wh.
