Hard as a diamond?
Superhard materials can slice, drill and polish other objects. They also hold potential for creating scratch-resistant coatings that could help keep expensive equipment safe from damage.
Now, science is opening the door to the development of new materials with these seductive qualities.

Manganese may finally solve hydrogen fuel cells' catalyst problem
Manganese is known for making stainless steel and aluminum soda cans. Now, researchers say the metal could advance one of the most promising sources of renewable energy: hydrogen fuel cells.
In a study a University at Buffalo-led research team reports on catalysts made from the widely avail ... more
Lego-like chemical building blocks self-assemble into catalyst for hydrogen fuel cells
What's better than platinum?
In hydrogen fuel cells, the answer is cofacial cobalt porphyrins.
It's a mouthful to say, and if you're not a chemist, you've probably never heard of these compounds before. But these molecules -- which are great at facilitating a chemical reaction that's needed ... more
