Scientists develop graphene microchips that are 100 times smaller and thousands of times faster than conventional ones, and promise to revolutionize the industry in the world

Graphene microchips promise to revolutionize industry worldwide, making computers and phones work thousands of times faster!

Physicists from the University of Sussex have developed the smallest microchips ever – 100 times smaller than conventional microchips, from graphene and other 2D materials, using a 'nano-origami' shape. They believe this next generation of microchips could make computers and phones run thousands of times faster.

By creating folds in the graphene structure, the researchers were able to make the nanomaterial behave like a transistor. When a strip of graphene is bent in this way, it acts like a microchip, but it is 100 times smaller than conventional microchips!

“We are creating mechanical folds in a layer of graphene,” says Professor Alan Dalton from the School of Mathematical and Physical Sciences at the University of Sussex. “It's a bit like nano-origami. Using these nanomaterials will make our computer chips smaller and faster. It is absolutely critical that this happens, as computer manufacturers are now at the limits of what they can do with traditional semiconductor technology. Ultimately, this will make our computers and phones thousands of times faster in the future.”

BEAUTY AND PERSONAL CARE

Dalton calls this type of technology 'straintronics' and says that the use of nanomaterials will allow space for more chips inside any device. “Everything we want to do with computers – to speed them up – can be done by bending graphene like this.”

Nanomaterial much smaller than conventional ones promises to be more sustainable and faster

The Doctor. Manoj Tripathi, a researcher in nanostructured materials at the University of Sussex and lead author of the paper, adds: "Rather than having to add foreign materials to a device, we show that we can create structures from graphene and other 2D materials simply by adding deliberate bends to the structure. structure. By making this kind of corrugation, we can create a smart electronic component, like a transistor, or a logic gate.”

It could also be greener and more sustainable as the process runs at room temperature and no additional materials need to be added, it uses less energy than traditional microchip manufacturing.

The development is detailed in research published in the ACS Nano Journal.

Brazil gained the first and largest graphene production factory in South America, capable of producing up to 5.000 kg per year, which together with niobium will revolutionize the destiny of humanity!

The inauguration of the first and largest industrial-scale graphene production plant in South America, took place on July 09, 2021. The unit has the capacity to produce up to five thousand kilos of high quality per year.

Graphene is a material recognized worldwide for its incredible physical properties, such as high mechanical strength, lightness, malleability and high thermal and electrical conductivity. Brazil is the third largest supplier of the mineral graphite in the world and has the second largest world reserve of this material, which is the main raw material for graphene. It is estimated that this market will move, in 5 years, more than 3 billion dollars.

Among the products that use this raw material are bulletproof vests, anticorrosive, self-cleaning and antibacterial paints, fabrics, motorcycle helmets, rebar for civil construction, batteries, among others.

The Civil House monitors the policies for advanced materials to promote the harmonization and regulation of this topic with the various sectoral actions carried out by the other ministries.
