Solar cells are subjected to a lot of harmful ultraviolet light, as they're typically placed for maximum sunlight exposure. A new eco-friendly coating could help protect them from those UV rays ...

A recent study has demonstrated that nanocellulose films infused with red onion skin extract exhibit superior UV-blocking properties.

Researchers at the University of Turku, Finland, investigated how to use bio-based materials to produce effective UV protection films for solar cells. The study, published in ACS Applied Optical ...

The first onion muscle prototypes are very small -- just a few onion cells long. They were created from the thin, translucent layer of epidermal cells that lie just below the dry outer skin of the ...

The onion cells provide some advantages over previous attempts to use living muscle cells to create artificial tissue, Shih says.

Because of the onion’s unique cell structure, the new artificial muscle is able to remain soft and bendable while it’s contracting, a trick that has eluded previous artificial muscle design.

When it comes to cooking with onions, chances are you throw away or compost the thin, translucent onion skin. However, the next time you're tempted to just toss those peels, you might want to give ...

Artificial muscles could one day revolutionize fields such as robotics, prosthetics and nanotechnology. So far, we've seen examples made from materials like electroactive elastomers, crumpled ...

Learn about the "onion skin" periosteal reaction that can occur with Ewing sarcoma. This article also discusses other signs of Ewing sarcoma.

Tweaking the voltages causes different movements; using two of these structures, the researchers turned the gold-plated onion skin into a pair of tweezers and used it to grab a cotton ball.
