A Graphene Mouth Screen

We are all intimate with face coverings to slow the spread of the coronavirus. Some are reusable, and some become waste after one use. [Dr. Ye Ruquan] and a research team from City University of Hong Kong, CityU, are developing an inexpensive reusable mask with outstanding antibacterial properties, and, get …read more

Graphene Prints More Smoothly Under the Influence of Alcohol

If you’ve ever sloshed coffee out of your mug and watched the tiny particles scurry to the edges of the puddle, then you’ve witnessed a genuine mystery of fluid mechanics called the coffee ring effect. The same phenomenon happens with spilled wine, and with functional inks like graphene.

The coffee …read more

“Graphene armor” protects perovskite solar cells from damage

Perovskite is emerging as a promising material for solar cells, but it has some durability problems. Now, engineers have developed a new electrode that could make them more stable, using a protective layer of “graphene armor.”Continue ReadingCategory: … Continue reading “Graphene armor” protects perovskite solar cells from damage

Graphene-boosted (and very long-lasting?) bike lube costs almost $150

Among its many other remarkable qualities, graphene is the world’s strongest human-made material. It’s perhaps not all that surprising, therefore, that it’s now been incorporated into a chain-protecting bicycle lubricant – and quite a pricey one, at th… Continue reading Graphene-boosted (and very long-lasting?) bike lube costs almost $150

Graphene-based sensor detects spoiled fish and meat

Graphene, the electrically-conductive “wonder material” made up of a one-atom-thick sheet of linked carbon atoms, already has many uses. It now has another, however, as the active ingredient in a sensor that detects food spoilage.Continue ReadingCatego… Continue reading Graphene-based sensor detects spoiled fish and meat

Atom-by-atom assembly makes for cheap, tuneable graphene nanoribbons

The wonder material graphene can take many forms for many different purposes, from transparent films that repel mosquitoes to crumpled balls that could boost the safety of batteries. One that has scientists particularly excited is nanoribbons for appli… Continue reading Atom-by-atom assembly makes for cheap, tuneable graphene nanoribbons

Graphene-based textile cools in the heat and warms in the cold

Scientists at the University of Manchester have developed a new type of smart textile that could make its way into adaptive clothing that keeps the wearer cool in warm weather, and vice versa. The material achieves this through the use of graphene whic… Continue reading Graphene-based textile cools in the heat and warms in the cold

MIT’s new roll-to-roll production method promises pristine graphene

Graphene may be a versatile material, but it remains very tricky to produce in large amounts. Now, an MIT team has found a new way to make large sheets of graphene in a roll-to-roll process, by depositing it onto a substrate that can easily be peeled o… Continue reading MIT’s new roll-to-roll production method promises pristine graphene

Never-before-seen “black nitrogen” plugs puzzle in periodic table

Researchers at the University of Bayreuth have created a form of nitrogen that’s never been seen before. Nicknamed “black nitrogen,” the new substance is crystalline, occurs in two-dimensional sheets, and could one day be useful in advanced electronics… Continue reading Never-before-seen “black nitrogen” plugs puzzle in periodic table

Graphene shows promise as solar sail material in ESA tests

ESA engineers are looking at using the world’s thinnest known material to build lighter, more efficient solar sails. By making sails out of one-atom-thick graphene sheets, the space agency aims to make sails capable of propelling unmanned interstellar … Continue reading Graphene shows promise as solar sail material in ESA tests
