Fabricating functional nano-devices is an ultimate goal of nanotechnology. Atomic-scale modification and sculpting of materials can enable nano-machines with wide-varying application potential in biological (medical) and chemical (trace sensing) uses.
Perfect sheets of diamond a few atoms thick appear to be possible even without the big squeeze that makes natural gems.
In the unusually warm winter that bridges the years 2013 and 2014, graphene continues to be a hot topic of investigation - and we mean "hot" in the physics sense.
Inspired by the ancient food art of 'blown sugar', Bando and his team reasoned that the strutted, coherent nature of conjoined bubbles would lend itself to strength and conductivity if graphene could be structured in the same way.
The discovery of what is essentially a 3D version of graphene -- the 2D sheets of carbon through which electrons race at many times the speed at which they move through silicon -- promises exciting new things to come for the high-tech industry, including much faster transistors and far more compact ...
New approach to use of 2-D carbon material opens up unexpected properties, could unleash new uses.
Graphene holds potential for diverse applications, including battery materials, electrodes, high-speed electronics, water filtration, and solar energy harvesting.
It's not just latex now but condoms made of graphene will be the next generation condoms with greater thinness and higher safety. The Microsoft tycoon and philanthropist Bill Gates, is offering funds of $100,000 the UK scientists to develop the next generation safer condoms-'graphene condoms'.
One of the methods used for examining the molecules in a liquid consists in passing the fluid through a nano-sized hole so as to detect their passage. Researchers have now found a way to improve this technique by using a material with unique properties: graphene.
Graphene for energy use is emerging as an exciting topic of research, with breakthrough discoveries hitting the headlines every week.
Graphene is considered the jack-of-all-trades of materials science: The two-dimensional honeycomb-shaped lattice made up of carbon atoms is stronger than steel and exhibits extremely high charge carrier mobilities. It is also transparent, lightweight and flexible. No wonder that there are plenty of ...
Graphene, with its enormous stiffness and low density, is an excellent material for nanoelectromechanical system (NEMS) applications. Such applications include various types of physical, biological, and chemical sensors, all expected to have superb sensitivities, exceeding those of competing technol...
