Sony managed to create a 100-meter long graphene sheet, largest in the world!

Sony has developed a new graphene producing process that use a roll-to-roll method. They have built a machine that can produce graphene sheets up to 100 meters in length (23 cm width), and the resulting sheet is the largest area graphene sheet in the world by far (the previous record was Samsung's 40" sheet from back in 2011):…

Nanométeres hullámok a grafén atomi szerkezetében (in Hungarian)

Az MTA TTK Műszaki Fizikai és Anyagtudományi Intézetében Tapasztó Leventének és munkatársainak először sikerült a grafén szerkezeti hullámzását nanométer alatti (0.7 nm) pontossággal szabályozni. Az eddig elérhető 300 nanométeres hullámhosszhoz képest ez óriási előrelépést jelent.

Aligned insulated graphene sheets hold promise for 3D chips

Researchers from Manchester University have used a new side-view imaging method to individually visualize graphene sheets in a layered insulated stack of sheets. They found out that each graphene layer in such a structure is perfectly aligned, even with 10 layers. This was a surprise as they expected the graphene to be distorted.



This means that stacking graphene sheets does not degrade their properties. This means that you can stack graphene to create 3D chips - which will have a…

Graphene may enable the ultimate water desalination device

MIT scientists have shown (in simulations) that nanoporous graphene can filter salt from water at a rate that is 2-3 orders of magnitude faster than today’s best commercial desalination technology, reverse osmosis (RO). This could lead to more efficient and smaller water desalination facilities.



The graphene is used as a membrane material that allows a flow of water with full salt refection via size exclusion. Other materials have been investigated for the same purpose, but the…

Researchers develop high-frequency flexible graphene transistors

Researchers developed a new process to make flexible transistors from graphene. The new process enable high electron mobility and high frequencies (in the Ghz range). The process uses a graphene in a solution and places it on polyimide substrates:

Shear stiffness and friction mechanics of single-layer graphene measured for the first time

Researchers from the University of Bristol have measured and identified for the first time the stress and strain shear modulus and internal friction of graphene sheets. Graphene is a material that has many potential groundbreaking uses in the electronics and composites industry. The research, in collaboration with the US Office of Naval Research, is published in Nano Letters.…

Graphene can be used to distill Alcohol, make drinks stronger...

A team of researchers led by Professor Sir Andre Geim demonstrated a graphene-Oxide based membrane that is impermeable to all gases and liquids (i.e. it's vacuum-tight) - but water can evaporate though it as if there's no membrane at all. This membrane can be used to remove water from a mixture or container. The team sealed a bottle of Vodka with such a membrane and this resulted in water evaporating - and the drink became stronger with time:…

Welcome - about us

Welcome! Nanopaprika was cooked up by Hungarian chemistry PhD student in 2007. The main idea was to create something more personal than the other nano networks already on the Internet. Community is open to everyone from post-doctorial researchers and professors to students everywhere.

There is only one important assumption: you have to be interested in nano!

Nanopaprika is always looking for new partners, if you have any idea, contact me at editor@nanopaprika.eu
