The Pièzo de Résistance

New Atom-Scale Products on Horizon: Breakthrough Discovery Enables Nanoscale Manipulation of Piezoelectric Effect

“The piezoelectric effect has never been manipulated at this scale before, so the range of possible applications is very exciting,” explained Pooja Tyagi, a PhD researcher in Professor Patanjali Kambhampati’s laboratory. “For example, the vibrations of a material can be analyzed to calculate the pressure of the solvent they are in. With further development and research, maybe we could measure blood pressure non-invasively by injecting the dots, shining a laser on them, and analyzing their vibration to determine the pressure.”

After dutifully reporting even the smallest profits on their tax filings this year, a number — though no one knows exactly what that number is — of Philadelphia bloggers were dispatched letters informing them that they owe $300 for a privilege license, plus taxes on any profits they made. Even if, as with Sean Barry, that profit is$11 over two years.
