Particulate Filter Research May Enable More Fuel-Efficient VehiclesExternal link

A team of researchers from the Energy and Transportation Science Division at the Department of Energy’s Oak Ridge National Laboratory is studying soot and ash collection and removal in particulate filters with neutron imaging, a technique sensitive enough to detect fine layers of material. Using the Neutron Imaging Facility instrument, beamline CG-1D, at ORNL’s High Flux Isotope Reactor, they are investigating the structure of particulate layers generated by a series of gasoline fuels.

Smooth Sailing: PPPL Develops an Integrated Approach to Understand How to Better Control Instabilities in an International Fusion DeviceExternal link

Simulations on Princeton Plasma Physics Laboratory computers show an approach for controlling instabilities in tokamaks that for the first time simultaneously simulates the plasma, the magnetic islands, and the feedback control from the waves that provide so-called electron cyclotron heating and current drive.

Solving the Dark Energy Mystery: A New Assignment for a 45-Year-Old TelescopeExternal link

The Mayall Telescope at the Kitt Peak National Observatory is preparing for a year-long overhaul and installation of the Dark Energy Spectroscopic Instrument (DESI). DESI will use an array of 5,000 swiveling robots, each carefully choreographed to point a fiber-optic cable at a preprogrammed sequence of deep-space objects, including millions of galaxies and quasars, which are galaxies that harbor massive, actively feeding black holes.
