SPLAT!
At PNNL, scientists are collaborating with physical chemistry scientists to push the frontiers of quantitative imaging of natural and artificial nanoparticles, by using single particle laser ablation time-of-flight mass spectrometry – more affectionately known as SPLAT II. The photo shows a scanning electron microscope image of a gold nanorod array used to calibrate the SPLAT II system.

Kept in the Dark
Photomultiplier tubes at the top of the LUX detector. Scientists aim to use the 370 kg liquid xenon time-projection chamber to directly detect galactic dark matter in a laboratory – one mile beneath the earth’s surface. “Welcome to my underground lair...”
