UK-based planarTECH has recently launched an equity crowdfunding campaign on Seedrs, as part of Graphene-Info's Graphene Crowdfunding Arena. We are happy to announce that the campaign reached 100% funding today. You can still take part in this exciting campaign, as PlanarTECH still accepts new investors via Seedrs.

PlanarTECH supplies Chemical Vapor Deposition (CVD) systems for the growth of graphene, and has already installed over 65 systems worldwide, to customers such as the University of Manchester, the University of Cambridge, Stanford University and the National University Singapore.

Remember, when investing your capital is at risk.

Since planarTECH's business encompasses the entire graphene value chain (from academics to producers to application developers) the company would like to call out to all graphene professionals and others who may be interested to take part in this exciting graphene crowdfunding project.

planarTECH is aiming to raise at least £350,000, but even small investments (as little as £10) are welcome and encouraged since the company is set on making this a graphene community endeavor. Don't miss your chance to be a part of an early stage and promising graphene technology company!

UK-based planarTECH has launched an equity crowdfunding campaign on Seedrs, as part of Graphene-Info's Graphene Crowdfunding Arena. planarTECH aims to expand its current business and also initiate new graphene endeavors. Investors are now able to participate in this financing round.

Here's our interview with planarTECH's co-founder and CEO, J. Patrick Frantz - who explains the company's technology, business and future plans.

A team of researchers at IIT-Gandhinagar in India has discovered an unexpected phenomenon that could have significant implications on the existing protocols followed to synthesize graphene and other two dimensional (2D) nanomaterials.

A popular method to synthesize graphene is liquid-phase exfoliation, in which the graphite powder is mixed in a suitable liquid medium and exposed to bursts of high-intensity sound energy (ultrasonication). This ultrasonic energy delaminates the layered parent crystals into daughter nanosheets that suspend and swim in the organic solvents to form a stable dispersion of 2D nanomaterials.

Researchers from Northwestern University have created 2D heterostructures from graphene and borophene, taking an important step toward creating intergrated circuits from these nanomaterials.

"If you were to crack open an integrated circuit inside a smartphone, you'd see many different materials integrated together," said Mark Hersam, Walter P. Murphy Professor of Materials Science and Engineering, who led the research. "However, we've reached the limits of many of those traditional materials. By integrating nanomaterials like borophene and graphene together, we are opening up new possibilities in nanoelectronics."

A new study from Queen Mary University of London finds that graphene is in fact a 3D material, as well as a 2D material. This Realization is said to be important for understanding its mechanical properties and for developing novel graphene-based devices.

In this study, the researchers asked two fundamental questions: to what extent is graphene graphite, and what is the true thickness of graphene? To their surprise, they found that 2D graphene, which is a flat single layer of carbon atoms arranged in a honeycomb structure, has many of the same mechanical properties as 3D graphite, which is a naturally occurring form of carbon made up from a very weak stack of many layers of graphene. They show that graphene shares a similar resistance to compression as graphite and that it is significantly thicker than is widely believed.

Manchester University’s Graphene Engineering Innovation Center (GEIC) is to host the world’s first Graphene Hackathon on Saturday 16 and Sunday 17 November 2019, in which teams will compete to develop and prototype innovative product ideas using conductive graphene inks.

The GEIC, which specializes in the rapid development and scale up of graphene and other 2D materials applications will host the event over 24 hours. IP, business and technical expertise will be on hand to help develop your innovative ideas, requiring no prior experience with graphene or programming.

Past studies by various research groups around the world were able to demonstrate origami-like folding of graphite with a scanning probe, but could not command where or how the folds would occur. Now, by replacing the graphite with high-quality graphene nanoislands, researchers in China and the US have leveraged the atomic-level control of STM into an origami nanofabrication tool with an impressive level of precision.

Similar to conventional paper origami, our current work has made it possible to create new complex nanostructures by custom-design folding of atomic layer materials, says Hong-Jun Gao, a researcher at the Chinese Academy of Sciences (CAS) who led this latest work. Alongside Shixuan Du and collaborators at CAS, as well as Vanderbilt University and the University of Maryland in the U.S, Gao reports how they can fold single layers of graphene with the direction of the fold specified over a range from around the magic angle at 1.1° (where observations of correlated electron behavior have been causing such a stir) to 60°, with a precision of 0.1°. Their STM manipulations also leave tubular structures at the edges that have one-dimensional structure electron characteristics similar to carbon nanotubes.

Researchers from Stanford, NIST, Theiss Research and several others have designed a new heat protector that consists of just a few layers of atomically thin materials, to protect electronics from excess heat.

The heat protector can reportedly provide the same insulation as a sheet of glass 100 times thicker. We’re looking at the heat in electronic devices in an entirely new way, said Eric Pop, professor of electrical engineering at Stanford and senior author of the study.

Israel's Bar Ilan University (BIU) will establish a nanotechnology excellence center in collaboration with the Chinese Academy of Sciences (CAS). The new center at the BIU will include a laboratory to focus on nanomedicine research and two-dimensional (2D) materials engineering, mainly producing graphene.

According to BIU, the main task of the joint research lab is to integrate teamwork of Chinese and Israeli researchers with the participation of industrialists from both countries.
