Silicon has been the material of choice for electronics for decades, but it’s beginning to bump up against efficiency limits. The next step could be carbon transistors and circuits, and now engineers at UC Berkeley have created metallic graphene nanori… Continue reading Metalized graphene nanoribbons make wires for all-carbon electronics
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
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

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
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, 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
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
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
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
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
