#Fiber-like light emitting diodes for wearable displays A research team at Korea Advanced Institute of Science
and Technology (KAIST) has developed fiber-like light emitting diodes, applicable to wearable displays. Professor Kyung-Cheol Choi and his research team from the School of Electrical engineering at KAIST have developed fiber-like light emitting diodes,
which can be applied in wearable displays. The research findings were published online in the July 14th issue of Advanced Electronic Materials.
Instead, they focused on fibers, a component of fabrics, and developed a fiber-like light emitting diode that has the characteristics of both fabrics and displays.
The essence of this technology, the dip coating process, is to immerse and extract a three dimensional (3-D) board that looks like a thread in a solution.
The researchers said that this technology would accelerate the commercialization of fiber based wearable displays
"Our research will become a core technology in developing light emitting diodes on fibers, which are fundamental elements of fabrics.
The experiment confirmed that quantum communication is feasible over long distances in fiber. Other research groups have teleported quantum information over longer distances in free space,
"Only about 1 percent of photons make it all the way through 100 km of fiber, "NIST's Marty Stevens says."
"Until now, so much quantum data was lost in fiber that transmission rates and distances were low. The new NTT/NIST teleportation technique could be used to make devices called quantum repeaters that could resend data periodically
By swapping in different genes for the tail fiber, they generated phages that target several types of bacteria."

They then apply ultralow magnetic fields to individual sections of the composite material--the ceramic fibers immersed in liquid plastic--to align the fibers according to the exacting specifications dictated by the product they are printing."

#Stretchable Conducting Fiber Provides Super Hero Capabilities The list of potential applications for a new electrically conducting fiberrtificial muscles,
The fiber, made from sheets of carbon nanotubes wrapped around a rubber core, can be stretched to 14 times its original length
An international research team based at the University of Texas at Dallas initially targeted the new super fiber for artificial muscles and for capacitors
whose storage capacity increases tenfold when the fiber is stretched. However the researchers believe that the material could be used as interconnects in flexible electronics and a host of other related applications.
In research published in the journal Science, the team describes how they devised a method for wrapping electrically conductive sheets of carbon nanotubes around the rubber core in such a way that the fiber's resistance doesn change when stretched,
