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.
planarTECH recently launched its 2AM graphene-enhanced face masks, in collaboration with IDEATI. The company (which is now in the last two days of its successful crowdfunding financing round in our Graphene Crowdfunding Arena) was kind enough to send us a few samples of the masks for a short hands-on review.
The face mask has a design that uses unique graphene and other carbon nanomaterials coatings that take advantage of graphene's antibacterial and antistatic properties. The coating has been certified by the Thailand Textile Institute to reduce staphylococcus aureus (ATCC 6538) bacteria by 99.95% within a 24 hour period, and it also repels dust. The mask is washable and reusable (up to 10 times).
Researchers at Berkeley Lab, in collaboration with the Institute for Basic Science (IBS) in South Korea, Monash University in Australia, and UC Berkeley, have developed a technique that produces atomic-scale 3D images of nanoparticles tumbling in liquid between sheets of graphene.
This is an exciting result. We can now measure atomic positions in three dimensions down to a precision six times smaller than hydrogen, the smallest atom, said study co-author Peter Ercius, a staff scientist at Berkeley Lab’s Molecular Foundry.
As researchers and companies all over the world set out to battle the Coronavirus pandemic, many are revisiting graphene as a material with potential for helping to win this fight. The reasons for such potential could be found in graphene's known antibacterial/antiviral properties, its beneficial traits for medical sensors and devices and more.
Graphene has been shown in the past as extremely useful for creating various sensors. Earlier this month, a team led by Boston College researchers used a sheet of graphene to track the electronic signals inherent in biological structures, in order to develop a platform to selectively identify deadly strains of bacteria. In October 2019, Rice University team under chemist James Tour transformed their laser-induced graphene (LIG) into self-sterilizing filters that grab pathogens out of the air and kill them with small pulses of electricity. Commercially sold graphene-based sensors exist, like the graphene oxide (GO) sensor developed by the ICN2 Nanobioelectronics and Biosensors group that was added in 2016 to the list products offered by Biolin Scientific, a prestigious instrumentation company devoted to the production of analytical devices. The Q-Sense GO sensor enables interaction studies of GO with various analytes (measured substances) of interest and may open the door to various applications with interest for diagnostics, safety/security and environmental monitoring.
UK-based planarTECH is launching an equity crowdfunding campaign at on Seedrs, as part of Graphene-Info's Graphene Crowdfunding Arena, and the company now released its first investor video pitch that summarizes the business and technology:
planarTECH is the first company to apply to our Graphene Crowdfunding Arena, and potential investors can currently pre-register for exclusive early access to this campaign. The first step should be to join Seedrs as an investor (which will also enable the participation in future graphene campaigns) and then to apply to planarTECH’s investment page as an interested investor. The company's campaign will go live soon!
A team of researchers at the Rice University lab of chemist James Tour has designed a ‘Green’ process that produces pristine graphene in bulk using waste food, plastic and other materials. According to the team, this process can help facilitate a reduction of the environmental impact of concrete and other building materials.
The new process can turn bulk quantities of just about any carbon source into graphene flakes. The process is quick and cheap; Tour said the flash graphene technique can convert a ton of coal, food waste or plastic into graphene for a fraction of the cost used by other bulk graphene-producing methods.
Rice University researchers have recently taken the idea of wearable devices that harvest energy from movement to a new level. Prof. James Tour's lab has adapted laser-induced graphene (LIG) into small, metal-free devices that generate electricity.
Putting the LIG composites in contact with other surfaces produces static electricity that can be used to power devices. This relies on the triboelectric effect, by which materials gather a charge through contact. When they are put together and then pulled apart, surface charges build up that can be channeled toward power generation.
