Unexpected speed-dependent friction in graphene

Due to their low-friction properties, materials consisting of single atomic layers are of great interest for applications where the aim is to reduce friction—such as hard disks or moving components for satellites or space ...

Can microrobots improve the safety of dairy products?

The Staphylococcus aureus bacterium commonly causes infections in dairy cows, leading to inflammation of the udder tissue, or mastitis, and lower milk quality. In research published in the journal Small, investigators developed ...

Microstructured fiber measures the size of nanoparticles

Researchers at Leibniz Institute of Photonic Technology (Leibniz IPHT) developed a new glass fiber design that enables exceptionally long observations of a large number of individual, freely moving nanoparticles in a liquid. ...

'Virtual pillars' separate and sort blood-based nanoparticles

Engineers at Duke University have developed a device that uses sound waves to separate and sort the tiniest particles found in blood in a matter of minutes. The technology is based on a concept called "virtual pillars" and ...

Researchers develop a safer carrier for cancer vaccines

Lipid nanoparticle (LNP)-based messenger ribonucleic acid (mRNA) vaccines have recently emerged as a promising strategy for the prevention and treatment of cancers, as well as infectious diseases. LNPs are carriers that safely ...

Positively charged nanomaterials treat obesity anywhere you want

Researchers have long been working on how to treat obesity, a serious condition that can lead to hypertension, diabetes, chronic inflammation, and cardiovascular diseases. Studies have also revealed a strong correlation of ...
