Solar fuels working well under pressure

Highly fuel-efficient new engine designs could significantly reduce the environmental impact of vehicles, especially if the engines run on renewable nonpetroleum-based fuels. Ensuring these unconventional fuels are compatible ...

Researchers determine why pulsed sparks make for better ignition

Researchers in the Oregon State University College of Engineering have learned the mechanisms behind a means of improved ignition, helping to open the door to better performance in combustion systems ranging from car engines ...

Potential for a cleaner blend of fuel

A technique modeling the combustion characteristics of gasoline blended with biofuels for cleaner and more efficient fuels.

Plasma from lasers can shed light on cosmic rays, solar eruptions

Lasers that generate plasma can provide insight into bursts of subatomic particles that occur in deep space, scientists have found. Such findings could help scientists understand cosmic rays, solar flares and solar eruptions—emissions ...

Plasma optic combines lasers into superbeam

Since its introduction in the 1977 film "Star Wars," the Death Star has remained one of science fiction's most iconic figures. The image of Alderaan's destruction at the hands of the Death Star's superlaser is burned into ...

Experiments shine light on exotic cosmic rays

The Earth is under constant bombardment by subatomic particles called cosmic rays, including some, known as ultra-high-energy cosmic rays, which pack much more punch than the world's most powerful particle accelerators. Fortunately, ...
