PHILADELPHIA — It is helpful — even life-saving — to have a warning sign before a structural system fails, but, when the system is only a few nanometers in size, having a sign that’s easy to read is a challenge. Now, thanks to a clever bit of molecular design by University of Pennsylvania and Duke University bioengineers and chemists, such warning can come in the form of a simple color change.
PHILADELPHIA — A team of University of Pennsylvania physicists has shown how to disrupt the “coffee ring effect” — the ring-shaped stain of particles left over after coffee drops evaporate — by changing the particles' shape. The discovery provides new tools for engineers to deposit uniform coatings.
