Atomic Structure of Irradiated Materials Is More Akin to Liquid Than Glass

JCP030718-Bauchy-quartz-sample.png

Materials exposed to neutron radiation tend to experience significant damage. At the nanoscale, these incident neutrons collide with a material’s atoms, which then collide with each other. The resulting disordered atomic network resembles those...

Neptune: Neutralizer-Free Plasma Propulsion

POP055705-Dedrick-Neptune.jpg

The most established plasma propulsion concepts are gridded-ion thrusters that accelerate and emit a larger number of positively charged particles than those that are negatively charged. To enable the spacecraft to remain charge-neutral, a...

Understanding Stars: How Tornado-Shaped Flow in a Dynamo Strengthens the Magnetic Field

POF064705-Varela-schematic-VKS.jpg

A new simulation based on the von-Kármán-Sodium (VKS) dynamo experiment takes a closer look at how the liquid vortex created by the device generates a magnetic field. Researchers investigated the effects of fluid resistivity and turbulence on the...

Can the Motion of Checking Your Smartwatch Charge It?

Triboelectric nanogenerators (TENGs) are small devices that convert movement into electricity, and might just be what bring us into an era of energy-harvesting clothes and implants. But could TENGs, even theoretically, give us wearable electronics...

The Spin Racket: Ping-Pong Champs Are Intuitive Masters of Fluid Dynamics

Curve balls may help a pitcher strike out batters in baseball; and some nasty spin can make an opponent sweat to return a tennis serve. But more so than in any other ball game, in table tennis – where the ball is so light and so small –dedicated...
