Dense hydrogen in a new light

(Phys.org) —Hydrogen is the most abundant element in the universe. The way it responds under extreme pressures and temperatures is crucial to our understanding of matter and the nature of hydrogen-rich planets.

Quantum effect triggers unusual material expansion

You know how you leave space in a water bottle before you pop it in the freezer—to accommodate the fact that water expands as it freezes? Most metal parts in airplanes face the more common opposite problem. At high altitudes ...

A step toward reduced nitrogen-oxide emissions in vehicles

Stricter environmental regulations enacted in the last few years are putting a squeeze on emissions from car engines, including nitrogen oxide. While modern "lean-burn" gasoline and diesel vehicles use less fuel, they also ...

Discovery of an Unexpected Boost for Solar Water-Splitting Cells

(PhysOrg.com) -- A research team from Northeastern University and the National Institute of Standards and Technology has discovered, serendipitously, that a residue of a process used to build arrays of titania nanotubes—a ...

Physicists uncover secrets of world's thinnest superconductor

Physicists from across three continents report the first experimental evidence to explain the unusual electronic behavior behind the world's thinnest superconductor, a material with myriad applications because it conducts ...

New efficient, low-temperature catalyst for hydrogen production

Scientists have developed a new low-temperature catalyst for producing high-purity hydrogen gas while simultaneously using up carbon monoxide (CO). The discovery-described in a paper set to publish online in the journal Science ...
