A team of researchers from various disciplines at the U.S. Naval Research Laboratory (NRL), Electronics Science and Technology and Materials Science and Technology Divisions, has showed hyperthermal ion implantation (HyTII) as a viable means of substitutionally doping graphene with nitrogen atoms. The outcome is a low-defect film with a tunable bandstructure agreeable to a number of device applications and platforms.
Recently, flexible organic light-emitting diodes (OLEDs) manufactured on a plastic substrate have gained much publicity for their application in advanced displays, which can be rolled or bent while in operating mode. In the future, it would probably be possible to roll up thin and lightweight computer just like a sheet of paper.
A graphene-based electrical nano-device has been developed which could considerably enhance the energy efficiency of vehicles powered by fossil fuels. The nano-device, referred to as a 'ballistic rectifier', is capable of converting heat into a usable electrical current, which would otherwise be wasted from the engine body and car exhaust.
Researchers at Rice University have developed a graphene-based de-icer to provide dual purpose. The novel material continues to melt ice from wings and wires when it becomes too cold. However, if the air is above 7°F, ice would not form at all.
Quantum mechanics is the branch of physics concerned with the behavior of things at atomic scales, where things work much differently from our daily world.
The discovery of wonder material graphene was awarded the Nobel Prize in Physics in 2010. The material contains a layer of carbon atoms set in a honeycomb lattice. However, the study of graphene did not stop at this point. New fascinating properties of graphene are still being discovered. Now, an international group of scientists have described the strange behavior of electrons passing through thin constrictions in a layer of graphene. These findings have been published in the Nature Communications journal.
Researchers at The University of Manchester have demonstrated that when a small amount of graphene is added to thin rubber films, they become significantly stretchier and stronger.
Researchers have created a different type of graphene-based transistor and through modelling they have confirmed that it consumes very low power when compared to other equivalent transistor devices. These results have been published in the Scientific Reports journal.
Electronic materials are the main tentative block for the development of flexible electronics as current materials do not work properly once broken and healed. An international team of researchers developed a new electronic material, which can heal all of its functions spontaneously even after being broken numerous times. This material can increase the strength of wearable electronics.
Directa Plus, a producer and supplier of graphene-based products for use in consumer and industrial markets, has announced its intention to float on London’s AIM stock exchange in order to boost its growth strategy.
