DIY Graphene | jenslabs

I came across a much inspiring video about some scientists at UCLA who successfully made some graphene and using only commercially available equipment doing it. After watching this I just had to look in to what it would take to make some graphene and perhaps a super capacitor or two of my own. Graphene is a fascinating material and…

Hydroplastic foaming of graphene aerogels and …

Direct foaming from solids is the most efficient method to fabricate porous materials. However, the ideal foaming fails to prepare aerogel of nanoparticles because the plasticity of their solids is denied by the overwhelming interface interactions. Here, we invent a hydroplastic foaming method to directly convert graphene oxide solids into aerogel bulks and microarrays, replacing the prevalent ...

2D Materials - IOPscience

2D Materials™ is a multidisciplinary, electronic-only journal devoted to publishing fundamental and applied research of the highest quality and impact covering all aspects of graphene and related two-dimensional materials.

Super-elasticity of three-dimensionally cross-linked ...

Until now, materials with high elasticity at deep cryogenic temperatures have not been observed. Previous reports indicated that graphene and carbon nanotube–based porous materials can exhibit reversible mechano-elastic behavior from liquid nitrogen temperature up to nearly a thousand degrees Celsius. Here, we report wide temperature–invariant large-strain super-elastic behavior in three ...

Graphene - Videos

Graphene is not yet as ubiquitous as plastic or silicon, however, and producing the material in bulk remains a challenge. Because graphene's properties rely on it being only one atom thick, until recently, it was only possible to make it in small patches or flakes. Physicists at Penn have discovered a way around these limitations, and have spun ...

Graphene Batteries

2014-12-2 · Graphene batteries are new technology and as of 2013, they are just entering mass production. This means that they are still under research. Optimal manufacturing processes are yet to be discovered. There is a lack of knowledge in this area, and peer-reviewed scientific materials are still scarce. We will try to explain the working principle ...
