(a) A pump pulse creates the plasma on a solid while a probe pulse monitors the time evolution. The top panel in b shows the spatially randomized magnetic field in the plasma while the figure at the bottom shows the power spectrum of the magnetic field (magnetic energy density variation of with inverse of spatial length. The curve indicates magnetic turbulence in the plasma and mimics that from the solar wind.
'The climate benefit of cellulosic biofuels is actually much greater than was originally thought,' said Phil Robertson, University Distinguished Professor of Ecosystem Science at Michigan State University.

Reaction mechanism with a catalyst for fuel cells that use hydrogen and carbon monoxide as fuels.
Although the vacuum chamber in the British fusion reactor JET has a wall made of solid metal, it can melt if it gets hit by a beam of runaway electrons. It is these runaway elementary particles that doctoral students Linnea Hesslow and Ola Embréus have successfully identified and decelerated.
In a new study, Professor Kumar and graduate student Meredith Richardson find that using corn for biofuel comes with greater environmental costs and fewer benefits than using corn for food.
This is a diagram of the mechanical structure of the capillary.
Smaller and lighter than traditional solar panels, the Roll-Out Solar Array, or ROSA, consists of a center wing made of a flexible material containing photovoltaic cells to convert light into electricity.
Materials scientists at Argonne National Laboratory synthesized these single crystals of a metallic trilayer nickelate compound via a high-pressure crystal growth process. A team led by John Mitchell, an Argonne Distinguished Fellow and associate director of the laboratory's Materials Science Division, describe the compound's potential as a high-temperature superconductor in the June 12 issue of Nature Physics.
Domain Walls research is pictured.
The long-term battery aging test was set up at WMG's Energy Innovation Centre.
Dr. Mahmoud Dhimish's research will mean low energy bills for consumers.
Proton hopping plays an important role in the reaction, as it activates nitrogen gas even at low temperatures and moderates the harsh condition requirements.
Using the HLRS Hazel Hen machine, RWTH Aachen University researchers were able to run a DNS simulation on a system of 45,000 particles at the Kolmogorov scale. To the team's knowledge, this is the direct-particle simulation for the largest number of particles at this scale to date, and serves as a benchmark for how other researchers studying this process can get more realistic simulation results.
The (110) surface of rutile tin oxide with tin atoms marked in purple and oxygen atoms marked in red. Labels denote the catalytically active sites that were considered in this study. H and CO2 adsorbates prefer binding to the Obr site.
A high-resolution electron microscope image (right) of the platinum electrocatalytic layer coated with molybdenum. The platinum catalyzes the hydrogen-evolution reaction (left) in acidic medium from protons in the electrolyte while the molybdenum layer inhibits water-forming reactions.
Millimeter-wave radars covering several tens of meters could be on cars, bikes, and smartphones. This might create a lot of new applications including games.
Argonne chemists Dugan Hayes, Lin Chen, and Ryan Hadt have identified a rapid electronic process that could aid the water-splitting reaction in cobalt-containing catalysts. Cobalt catalysts are relatively inexpensive and could replace more expensive precious metal catalysts in the production of clean energy, most notably solar fuels.
