So, miscalculating the shape of a molecule changes the predicted reaction rates (e.g., the speed at which things happen) exponentially. Tiny errors matter a lot.

To make fuel cells more economical, engineers want a fast and efficient iron-based molecule that splits hydrogen gas to make electricity. Researchers now report such a catalyst. It is the first ...

The hydrogen molecule also gains energy from the electrons that pass through. It starts to wave back and forth, like a branch in the wind. And, after a moment, it jumps out from under the tip.

Fuel cells use a platinum catalyst—essentially a chunk of metal—to crack a hydrogen molecule open like an egg: The electron whites run out and form a current that is electricity.

A leading proposal suggested that KP1212 derived its mutagenicity by shape shifting—converting into a different molecular structure by repositioning its hydrogen atoms on nitrogen and oxygen atoms.

An international team led by chemists at the University of British Columbia (UBC), Canada, has reported strong experimental evidence for a superfluid phase in molecular hydrogen at 0.4 K. This phase, ...

An international research team has successfully achieved single-molecule spectroscopic observation of hydrogen (H2) and deuterium (D2) confined within a picocavity. The picocavity was formed ...

In aqueous solution, HF is a weak acid, with a pK a of 3.17, again in contrast with the other hydrogen halides, which are all completely ionized in solution. But there is nothing weak about HF’s other ...

“Our work shows that the smallest possible molecule, hydrogen, is capable of ‘pushing’ an oscillator 10 19 times bigger than itself,” adds Pascual, “This is a result that will spur us on to search for ...
