Quote:SARS-COV-2 INHIBITION BY HYBRID GRAPHENE NANOPLATELET/METAL OXIDE POWDERS
Posted By [b]Terrance Barkan[/b], Wednesday, November 18, 2020
Versarien Plc is pleased to announce the receipt of an independent report produced by Ankara University, Turkey, detailing the results of a preliminary study of modified graphene materials provided by Versarien for use against SARS-CoV-2, the strain of coronavirus that causes coronavirus disease 2019, COVID-19.  The Report concludes that the preliminary test results show that these materials significantly inhibit viral infection and possess anti-viral activity towards SARS-CoV-2.

The study was undertaken to test, in a laboratory environment, the hypothesis that graphene nanoplatelets doped with metal oxide nanoparticles, as produced by the Versarien group, can inactivate the SARS-CoV-2 coronavirus.

Quote:Supported by more than $900,000 in federal grants, Iowa State University engineers are using their expertise in graphene-based biosensors to develop better, cheaper, quicker, more accessible testing for the coronavirus that causes COVID-19.

Forget graphene, now we have "white graphene", made of a thin film of boron nitride.

LOL

I think this has been around a few years.   Any recent significant news?

Now I am intrigued by superconducting graphene.

Apparently this thread should've been about gallium, sorry everyone: https://www.wsj.com/articles/the-novel-m...nists_pos2

Quote:There are other potentially revolutionary materials that are [color=var(--color-blue)]beginning to compete with silicon, like graphene, but GaN microchips have the considerable advantage that they can be produced in the same sort of manufacturing facilities—called fabs—that make conventional microchips, says Stephen Oliver, head of marketing at Navitas.[/color]

I’m about a week late, but apparently the world’s thinnest Christmas tree has been made, with Graphene.

O Tannenbaum, o tannenbaum . . .

Quote:apart from a few niche uses in electronics, water filtration and some specialist sports equipment, graphene remains largely unemployed. Certainly, no killer application of the sort predicted when the stuff was discovered has emerged. But that could be about to change. Concrete is as far from superconductivity on the technological sexiness spectrum as it is possible to get. Yet it is an important material and of great concern to those attempting to slow down global warming, because the process of making it inevitably releases carbon dioxide. And graphene may hold the key to reducing that contribution considerably.

Lol, I was just coming to this thread to post that very link, and you beat me by 4 hours, after it had been over four months since the last post on this thread.

Ok, now graphene is intriguing.

BC

Well folks who love Cardboard might be among the few to reliably find Concrete intriguing.  The rest of the world? Not so much.

Do we need a new graphyne thread?

Anyways, here’s a potential biomedical application for graphene…

Semi yearly addition to this thread.

Quote: In the latest issue of Optics Express, the group reports that when using a 90mW laser, their tractor beam in a box can produce about a micronewton of pulling force. The setup is deceptively simple. The scientists vapor-coated a sliver of glass with reflective gold, and then stuck a flake of cross-linked graphene to the other side. Then, they pointed blue, cyan, and green lasers at the flake of graphene. Lo and behold, it moved toward the laser emitter.

Ok, this is legit pretty cool.

Graphene was used to enable a laser to function as a tractor beam, pulling a small object.

Almost like clockwork; I find another cool link about twice a year.

Graphene could be used in your next electric vehicle, though that's a lot of exponential extrapolation, and it won't reach parity with lithium ion until the 2030's.
