Controlling heat flow with atomic-level precision

Through a combination of atomic-scale materials design and ultrafast measurements, researchers at the University of Illinois have revealed new insights about how heat flows across an interface between two materials.

One-third of car fuel consumption is due to friction loss

No less than one third of a car's fuel consumption is spent in overcoming friction, and this friction loss has a direct impact on both fuel consumption and emissions. However, new technology can reduce friction by anything ...

3-D battery structure shows new twist in battery design

(PhysOrg.com) -- Battery life and driving range are two sticky phrases in discussions about why EVs have yet to hit mainstream use. Drivers still feel skittish about the idea of setting out on longer trips on batteries lasting ...

Watching particles' jekyll-to-hyde transformation

(PhysOrg.com) -- Whether a common atmospheric particle stays in a stable form or twists into something else depends on the amount of water it encounters in the atmosphere, according to scientists at the University of Iowa ...

Normal air could halve fuel consumption

Every time a car brakes, energy is generated. At present this energy is not used, but new research shows that it is perfectly possible to save it for later use in the form of compressed air. It can then provide extra power ...
