Glassy carbon microneedles: A new transdermal drug delivery device

Microneedles are designed to infuse medications transdermally (through the skin) and relatively painlessly during clinical applications. In a recent study, Richa Mishra and her colleagues developed a new technique to convert ...

What does a chemical do? Addressing misconceptions about chemistry

When I introduce myself as a Ph.D. student in chemistry, I can often spot fear and incomprehension in people's eyes: chemists are often pictured as crazy scientists, like Dr. Maru in Wonder Woman, doing black magic and explosions. ...

Stamp-sized graphene sheets riddled with holes could be boon for molecular separation

MIT engineers have found a way to directly "pinprick" microscopic holes into graphene as the material is grown in the lab. With this technique, they have fabricated relatively large sheets of graphene ("large," meaning roughly ...

World speed record for polymer simulations shattered by over a hundred-fold

From a humble plastic bag to ultra-light airplane wings, polymers are everywhere. These molecules are long chains of atoms that play many roles for good and bad, from organic photovoltaics to indestructible plastic pollution. ...
