The National Institute of Standards and Technology (NIST) houses a room-sized electromechanical machine called the NIST-4 Kibble balance. The instrument can already measure the mass of objects of roughly 1 kilogram as accurately as any device in the world. But now, NIST researchers have used graphene to further improved their Kibble balance’s performance by adding to it a custom-built device that provides an exact definition of electrical resistance.

The device is called the quantum Hall array resistance standard (QHARS), and it consists of a set of several smaller devices that use a quirk of quantum physics to generate extremely precise amounts of electrical resistance. The improvement should help scientists use their balances to measure masses smaller than 1 kilogram with high accuracy, something no other Kibble balance has done before.

In June 2022, Graphenea launched its latest product out of its Graphene Foundry, the mGFET, fully-packaged mini graphene-based field effect transistors.

Graphenea now updates that the market demand for these products has been excellent, and it has run out of stock. The company is now working to produce more mGFET devices and restock.

The mGFETs are Graphenea's highest value-chain products, which are manufactured and packaged in chip carriers, and can be used together with the Graphenea Card for seamless sensor development (which was released earlier in 2022, and has also seen very good reception in the industry).

WearGraphene recently launched its Gamma graphene-enhanced winter jacket. I have spent a couple of months with this jacket, including two trips to Europe during the springtime, and here's my review.

First of all, the jacket looks very sleek (in my opinion, of course), the material feels of high quality. It is quite light, and packs very easily. There are many pockets, Velcro bands and drawstrings, which is really useful and helps you to customize this jacket so that it fits perfectly.

Graphene has a great potential in the construction industry, to increase the performance of materials and structures, to reduce costs and to reduce the environmental footprint of one of the world's most polluting industries.

After years of R&D, it seems as if graphene is finally get ready for commercial adoption on the market. Here's a short interview we did with James Baker, the CEO at Graphene@Manchester who's behind much of the progress we've seen recently.

A few years ago, several graphene producers released 3D printing materials enhanced with graphene. These materials enabled conductive non-metal materials, and enhanced the mechanical and thermal properties of these 3D printing filaments.

The market reaction, though, to these materials was cool. The materials did not provide a significant improvement, the price was high, and there were better alternatives available.

A research team led by the University of Basel has found that the electronic properties of graphene can be specifically modified by stretching the material evenly.

The researchers, led by Professor Christian Schönenberger at the Swiss Nanoscience Institute and the Department of Physics at the University of Basel, have studied how the material’s electronic properties can be manipulated by mechanical stretching. In order to do this, they developed a kind of rack by which they stretch the atomically thin graphene layer in a controlled manner, while measuring its electronic properties.

India-based Nanomatrix Materials (NM Materials) produces graphene-oxide materials and derivatives (such as r-GO) at its 20Kg/month GO plant, and the company recently launched its own brand of graphene-enhanced face mask, the G1 Wonder mask.

A few weeks ago, NM Materials sent us a couple of masks for a review here at Graphene-Info, and this short review will summarize our findings.

Israel-based laser-induced graphene developer LIGC Application announced that its ViralWall air-purifier is now available for pre-order. The ViralWall costs $279, and will ship in April.

Using a graphene-based filter, the ViralWall "cleans the air from airborne bacteria and viruses and creates an invisible 1.2x1.6 meter air screen between people to prevent the spread of harmful airborne particles".

A while back we published our short storyboard video with an introduction to graphene. Today we published an updated edition for 2021, enjoy!

The International Graphene Awards (IGA) was initiated by the Chinese Graphene Industry Association (CGIA) in collaboration with 50 graphene experts from all over the world.

In 2020 the IGA committee offered 5 different awards: for best graphene products, best graphene firm, industry promotion, industry demonstration and honorary award for the most contribution people in graphene industry.
