High-purity hydrogen generated from a single device

(PhysOrg.com) -- There are many ways to generate hydrogen, such as water electrolysis and steam reforming of gas, but the hydrogen produced by these methods tends to be combined with other byproduct and residual gases. For ...

Team shatters theoretical limit on bio-hydrogen production

In 1977, researcher Rudolf Thauer proposed a theoretical ceiling on the amount of hydrogen that bacteria could produce via fermentation, the sugar-converting process also responsible for yogurt, beer and cheese.

New discovery may be breakthrough for hydrogen cars

A team of Virginia Tech researchers has discovered a way to create hydrogen fuel using a biological method that greatly reduces the time and money it takes to produce the zero-emissions fuel. This method uses abundantly available ...

When less is more: Fewer proton relays improve catalytic rates

(Phys.org) —By directly comparing three closely related catalysts, scientists at the Center for Molecular Electrocatalysis established that hydrogen production speed and efficiency are influenced by the molecules' structure ...

Lava dots: Scientists make hollow, soft-shelled quantum dots

(Phys.org)—Serendipity proved to be a key ingredient for the latest nanoparticles discovered at Rice University. The new "lava dot" particles were discovered accidentally when researchers stumbled upon a way of using molten ...
