Creating enough nanovesicles to inexpensively serve as a drug delivery system may be as simple as putting the cells through a sieve, according to an international team of researchers who used mouse autologous — their own — immune cells to create large amounts of fillable nanovesicles to deliver drugs to tumors in mice. Nanovesicles are…
Sulfur Holds the Secret to Safe, Rechargeable Lithium Batteries
We have come a long way from leaky sulfur-acid automobile batteries, but modern lithium batteries still have some down sides. Now a team of Penn State engineers have discovered a different type of lithium sulfur battery that could be more efficient, less expensive, and safer. “We demonstrated this method in a coin battery,” says Donghai…
Metamaterial Device Acts Like a Chameleon in Infrared
An electric current will not only heat a hybrid metamaterial, but will also trigger it to change state and fade into the background like a chameleon in what may be the proof-of-concept of the first controllable metamaterial device, or metadevice, according to a team of engineers. “Previous metamaterials work focused mainly on cloaking objects so…
