ArtSea Ink: A colorful, seaweed-based ink for 3D printing

Added: 04.08.2021 23:18 | 15 views | 0 comments

Some artists are embracing 3D printing as a new medium, allowing them to create intricate 3D compositions that are difficult to produce in any other way. But the rigid, plastic-based materials used in many 3D printers require high heat for workability. Now, researchers reporting in ACS Omega have developed a colorful new ink for 2D and 3D art made of mica pigments in alginate, a sugar from seaweed that forms a stable gel without heat.

Dissolvable smartwatch makes for easier electronics recycling

Added: 04.08.2021 23:18 | 18 views | 0 comments

Small electronics, including smartwatches and fitness trackers, aren't easily dismantled and recycled. So when a new model comes out, most users send the old devices into hazardous waste streams. To simplify small electronics recycling, researchers have developed a two-metal nanocomposite for circuits that disintegrates when submerged in water. They demonstrated the circuits in a prototype transient device -- a functional smartwatch that dissolved within 40 hours.

Toward a COVID-19 breathalyzer for kids

Added: 04.08.2021 23:18 | 17 views | 0 comments

Adults infected with SARS-CoV-2 exhale different metabolites in their breath than uninfected people. Now, researchers have shown that children infected with SARS-CoV-2 also show breath metabolite changes, but they're largely different from the ones in adults. Someday, this information could be used to quickly and easily screen children for infection, the researchers say.

Researchers develop coating for endotracheal tubes that releases antimicrobial peptides

Added: 04.08.2021 22:18 | 15 views | 0 comments

In a proof-of-concept study, researchers have created a coating that can be applied to endotracheal tubes and release antimicrobial peptides that target infectious bacteria with specificity. The innovation could reduce upper-airway bacterial inflammation during intubation, a situation that can lead to chronic inflammation and a condition called subglottic stenosis, the narrowing of the airway by an accumulation of scar tissue.
