A product using graphene – a light bulb coated in the much-hyped material – will be commercially available for the first time in the near future. Continue reading… “Graphene light bulb to be on the market soon, in the UK”
World’s thinnest lightbulb developed using graphene
A postdoctoral research scientist, Young Duck Kim, has led a team of scientists from Columbia, Seoul National University (SNU), and Korea Research Institute of Standards and Science (KRISS) that have demonstrated for the first time ever an on-chip visible light source using graphene, an atomically thin and perfectly crystalline form of carbon, as a filament.
New large-scale graphene fabrication
One of the barriers to using graphene on a commercial scale – fabrication size limits – could be overcome using a new method developed by researchers at theDepartment of Energy’s Oak Ridge National Laboratory(ORNL). Continue reading… “New large-scale graphene fabrication”
3D printing meets graphene
By 3DPRINT.GURU
Futurist Thomas Frey writes: ” In 2004, scientists Andre Geim and Kostya Novoselov from the University of Manchester, used adhesive tape to lift a thin layer of carbon from a block of graphite, and placed it on a silicone wafer. Graphite is the stuff commonly found in pencil lead. As simple as this sounds, what these two scientists had created was a 2-dimensional form of carbon known as graphene, and in 2010 they received the Nobel Prize in Physics for this discovery. But that’s only part of the story.” Continue reading… “3D printing meets graphene”
Graphene can Harvest Energy through Thin Air
(CNN) Bold claims for new battery technology have been around since the invention of the lead-acid battery more than 150 years ago.
But researchers at Manchester University in the UK say their latest discovery involving the new wonder material graphene could be the most revolutionary advance in battery technology yet.

The First Lady of Graphene
The birthplace of graphene – the one-atom-thick carbon – is Manchester University, where it was created by two physicists. But Cambridge could become the adopted home of the so-called wonder-material.
A vast new facility that can make up to five tons of the ultra-valuable black dust each year is being built in the city and is due to open in 2015.
Cambridge Nanosystems, a university spin-out, led by chief scientist Catharina Paukner, 30, has built the factory with the help of a £500,000 grant from the Technology Strategy Board.

Graphene-based supercapacitors will make battery-free electric cars possible
Another immediate benefit of the supercapacitor film technology is in charging time.
Researchers at Rice University and the Queensland University of Technology have conducted a study that has resulted in the creation of a graphene-based supercapacitor film that could possibly replace the need for a conventional battery in electric cars.

Graphene supercapacitors could provide energy for flexible electronics
A research team has created an energy storage device that is highly flexible and stretchy.
How long would your battery last if your phone was always awake and processing data? Would the battery last three hours? One hour? The next generation of electronics will require that kind of always-on energy consumption, but our current batteries are far from powerful enough to accommodate that.

Researchers hope to develop the world’s first graphene 3D printer
Graphene is pure carbon arranged in sheets that are only one atom thick.
The startup, 3D Graphene Labs, hopes to develop not only graphene materials for 3D printers, but a 3D printer designed for graphene printing. But we’re not so sure.

Top 10 ways nanotechnology is transforming the world around us
Nanotechnology might be outside your window at this very moment in the form of a gecko-like human scaling a self-cleaning, nano-enhanced solar window.
A pair of hand-held, gecko-inspired paddles that can help you ascend a 25-foot sheet of glass might not seem like the most impressive use of nanotechnology but this real-world advance aptly demonstrates how quickly the field of nanotechnology is climbing into our lives. Below are ten additional examples of how nanotechnology is already changing the world, followed by 10 ways it may help society scale even greater heights in the near future.

Researchers discover 3D material that behaves like graphene
This illustration depicts fast-moving, massless electrons inside cadmium arsenide.
Researchers from Oxford, SLAC, and Berkeley Lab have found that cadmium arsenide could yield practical devices with the same extraordinary electronic properties as 2D graphene. The researchers also found that the new “semimetal” material exists in a sturdy 3D form that should be much easier to shape into electronic devices such as very fast transistors, sensors and transparent electrodes.

Graphene contact lenses could give everyone night vision
Contact lenses with night vision could be on the way.
We all might be able to experience soon the super hero ability of having night vision thanks to graphene contact lenses. Contact lenses one day in the near future will be able to register the entire infrared spectrum as well as visible and ultraviolet light, according to Zhaohui Zhong, an assistant professor of electrical and computer engineering at the University of Michigan.
