Graphene hype

morreale Saturday 18 of July, 2015
Lux Research analysts report that graphene nanoplatelets are following the same path as multiwall carbon nanotubes. That is there is over capacity of graphene nanoplatelets and limited commercial applications for the materials. They also point out that most companies in the graphene space are not executing well and their technical value is unclear. They don't expect graphene to live up to the hype.

CVD Graphene growth on eutectic substrates

morreale Thursday 16 of July, 2015
Researchers have grown large area graphene on a eutectic substrate using a Platinum foil with a thin silicon film. When the substrate is heated a liquid platinum silicide layer forms and graphene grow with large crystals and very quickly compared to other CVD growth techniques. The liquid platinum slicide produces a smooth growth surface that hides the polycrystalline structure of the platinum foil. The Nature Communications paper Rapid epitaxy-free graphene synthesis on silicidated polycrystalline platinum is currently open access.

NanoTCAD ViDES IDE Beta

morreale Thursday 16 of July, 2015
A beta version of the NanoTCAD ViDES IDE is now available. It provides a graphical user interface to help simplify modeling of nanoscale devices like monolayer FETs. The nanoTCAD ViDES is free at the moment, runs on 64 bit Linux, and requires activation.

Graphene light bulb

System Administrator Thursday 18 of June, 2015
Researchers have produced light from transparent suspended graphene ribbons fabricated on a silicon dioxide and reported the results in the Nature Nanotechnology paper Bright visible light emission from graphene. The height of the graphene above the substrate is used to tune the output wavelength. The simulation is very cool as it shows violent vibrations of the graphene nanoribbons when light is emitted.

IEEE NTC Nano Blog

morreale Saturday 30 of May, 2015
The IEEE NanoTechnology Council has a blog on nanotechnology used to share the latest developments on the topic. Some of the papers highlighted in May 2015 include graphene devices, 3D magnetic devices, and Carbon NanoTube devices, for example.

Science Museum Blog on Graphene

morreale Saturday 30 of May, 2015
The Science Museum in the UK has posed a blog on the Secret of Scientific Creativity revealed by Andre Geim, ‘godfather of graphene’. The blog chronicles Andre Geim life, career, and his curiosity to learn and explore new things. His curiosity to understand diamagnetism lead him to levitate a frog and hamster in a strong magnetic field. The same curiosity helped lead to the isolation of a single sheet of carbon known as graphene.

Graphene standards

morreale Wednesday 22 of April, 2015
The Graphene Council Research road show presentation slides for Developing crucial industry standards for graphene and understanding the regulatory environment are now available. In this roads show presentation, The Graphene Council Research is advocating the development of industrial standards for graphene. Presently, there are no standards that define graphene and this is hindering the development and commercialization of the material. This presentation also provides some understanding the of the regulatory environment for the graphene and nanomaterials.
