As intricate electronics continue to develop, tools are also needed to fix them. In anticipation of this challenge, and inspired by the human body’s immune system, scientists have developed self-propelled nanomotors that locate and repair tiny scratches in the electronics systems. This development can lead to electrodes, solar cells, flexible batteries, and other devices to heal themselves.
Electronics manufacturers constantly hunt for ways to make faster, cheaper computer chips, often by cutting production costs or by shrinking component sizes. Now, researchers report that DNA, the genetic material of life, might help accomplish this goal when it is formed into specific shapes through a process reminiscent of the ancient art of paper folding.
Over the past two decades, nanoscale devices and nanomaterials have been increasingly developed. Flat graphene crystals have many potential applications in advanced superconductors or electronics, and they could usher in a new era of affordable medical imaging.
A study from Plymouth University has demonstrated that when electrical signals are transmitted through graphene at high frequencies, they do not lose any of their energy.
Ever since its discovery in 2004 graphene has been considered a wonder material, and researchers have great expectations for it. The material is 300 times stronger than steel, and a million times thinner than a human hair. It is also the world’s best conductor of electricity and heat. These features can positively impact many applications, such as making more powerful batteries, more efficient solar panels, and faster computers. Although, it is tough to manipulate graphene beyond it's two-dimensional form.
A recent study published in Science Advances reveals a method to manipulate graphene to create the world’s most light-absorbent material for its weight. The material is nanometer-thin and will facilitate futuristic applications such as 'smart wallpaper', which could produce electricity from waste heat or light, and power many applications within the increasing 'internet of things'.
An international research group led by physicists at the University of Arkansas created magnetic two-dimensional metal in an artificial oxide material that could be used to make better transistors.
Scientists at the University of Southampton have made a major step forward in the development of digital data storage that is capable of surviving for billions of years.
Graphene combines transparency, electrical conductivity, and high durability into a one-atom-thick sheet of carbon. Even though graphene is known to be a "wonder material," it has still not been successful in industrial and commercial processes and products.
Heterostructures formed by different three-dimensional semiconductors form the foundation for modern electronic and photonic devices. Now, University of Washington scientists have successfully combined two different ultrathin semiconductors — each just one layer of atoms thick and roughly 100,000 times thinner than a human hair — to make a new two-dimensional heterostructure with potential uses in clean energy and optically-active electronics. The team, led by Boeing Distinguished Associate Professor Xiaodong Xu, announced its findings in a paper published Feb. 12 in the journal Science.
