He also said unidentified  US citizens were also participating in the procedure, without elaborating on their capacity.Putin said an analysis of black box # would help determine downed jet's flight path."We have sufficient evidence that proves that the Russian aircraft did not violate Turkish airspace," said Sergei Dronov, the deputy head commander of the Russian air force, adding that the downed plane had been flying in Syrian airspace 5.Dronov said 14 countries had been invited to monitor the investigation but only China and the UK had accepted.State television broadcast the opening of the orange device on state television as military officials insisted it was intact as experts from China and Britain watched the procedure.The findings will be revealed on December 21, the air force said.5 kilometres (around three miles) from the border with Turkey.

Moscow: Russia today began examining the black box of its warplane that was shot down over Turkey's border with Syria, again contesting Ankara's claim it had violated Turkish airspace.

Wearing lab coats, technicians used screwdrivers, drills, and even a vacuum cleaner as they opened the device under the watchful eyes of military personnel and dozens of journalists.Turkey says the Russian jet strayed into its airspace and ignored repeated warnings, while Moscow insists it did not cross from Syria and accused Ankara of a planned provocation describing it as a "stab in the back"

Our work shows that ultra-flexible light emission on large areas can be realised on very lightweight textile electrodes," said Thomas Lanz from Umea University in Sweden.The fabric electrode consists of a weave of silver-coated copper wires and polymer fibres that are embedded in a polymer Wholesale Cube vacuum space bags matrix, all of which is coated with a conductive ink. "Traditionally, this was hard to come by, as these electrodes are typically quite rough.org'. Scientists have created a low-cost, flexible and light-weight textile material that may be used in light-emitting clothing, signs and architecture. We have demonstrated that the light-emitting electrochemical cell's inherent fault tolerance is ideally suited for this type of transparent substrate,” Lanz told 'Phys.. The light-emitting textile is made by spray-coating a light-emitting electrochemical cell (LEC) onto a transparent fabric-based electrode, which results in a simpler and less-expensive fabrication process compared to those used to make OLEDs. 

Researchers see huge applications for this technology in the field of wearables, as the device is highly conformal. The advantages of this new transparent fabric are its high flexibility, light weight, and low cost.As of now, the most common transparent and flexible light-emitting device technology is the organic light-emitting diode (OLED), whose fabrication process involves expensive vacuum technology, researchers said
