Colloids are particles that have a diameter of between approximately 1 and 1,000 nanometres and that are evenly dispersed in fluids. Colloids are also known as colloidal dispersions because the ...

Titanium micro-particles in the oral mucosa around dental implants are common. This is shown in a new study which also identified 14 genes that may be affected by these particles. Titanium micro ...

ETH Zurich Materials Scientists are the first to measure the microscopic forces involved when particles in suspensions such as concrete or paint roll past each other. Previously, such measurements ...

However, previous research has shown that even in those with no symptoms, gadolinium particles have been found in the kidney and the brain and can be detected in the blood and urine years after ...

Chewing gum released up to 637 microplastic particles per gram, with most particles released within the first 8 minutes. Both natural and synthetic gums released similar amounts. Chewing gum ...

The long-term effects of fiberglass exposure are not well documented. If fiberglass particles become lodged in your skin, you may notice a red, itchy rash known as contact dermatitis. This usually ...

That's because plants absorb microplastics in water and soil through their roots, and the majority of these particles become concentrated in this part of the plant with only a tiny amount ...

Discovering a machine that could somehow produce thrust without releasing propellant would be a game-changer for human space travel. There’s just one problem—such a device would defy the laws ...

By incorporating microfiber discharge electrodes and nonmetallic carbon plates, the system operates on low current yet removes more than 90% of ultrafine particles. Additionally, it resolves the ozone ...

The study, conducted by researchers from the University of California, Los Angeles (UCLA), analyzed saliva samples after chewing various gum brands. Lisa Lowe, a PhD student at UCLA, chewed seven ...

New research shows that chewing gum can release hundreds or possibly thousands of microplastics into saliva, which may then be absorbed into the body. Even all-natural gum sheds microplastics when ...
