Alert system for failing nuclear plant pipes uses thin films and sound vibrations

Oct. 24, 2019—A failing pipe can be tough to spot. It may cause a puddle, produce another sign of damage, or simply burst before detection. A flooded kitchen or laundry room is messy and inconvenient, but the stakes are much, much higher in nuclear power plants – which on average contain many miles of pipeline. As concern...

Flying saucer’ quantum dots hold secret to better, brighter lasers

Mar. 21, 2017—This computer-generated model shows the spherical core of the quantum dot nanoparticle (in red) along with the ‘flying saucer’ shape of the outer shell (in yellow). The tension in the core induced by the shell affects the electronic states and lowers the energy threshold required to trigger the laser. (Alex Voznyy/University of Toronto) Fresh insights...

Quantum dots made from fool’s gold boost battery performance

Nov. 11, 2015—  Anna Douglas holding one of the batteries that she has modified by adding millions of quantum dots made from iron pyrite, fool’s gold. (John Russell / Vanderbilt) If you add quantum dots – nanocrystals 10,000 times smaller than the width of a human hair – to a smartphone battery it will charge in 30...

7 Vanderbilt engineers who found winter break was prime time for research

Jan. 2, 2015—Relieved undergraduates turned in their finals and jetted off for winter break a few weeks ago, leaving the halls at Vanderbilt University School of Engineering almost unnervingly empty. But there’s no break for research. Anyone in need of company could find labs full of Ph.D. candidates working practically the whole time. “We joke that one...
