Platinum-free catalysts could make cheaper hydrogen fuel cells

The high cost of platinum catalysts used in hydrogen fuel cells limits the commercialization of fuel cell electric vehicles. Scientists are studying alternative catalysts to increase cost-effectiveness and maintain efficiency ...

In the far future, the universe will be mostly invisible

If you look out on the sky on a nice clear dark night, you'll see thousands of intense points of light. Those stars are incredibly far away, but bright enough to be seen with the naked eye from that great distance—a considerable ...

Micromotors get supercharged with three 'engines'

Someday, microscopic robots could perform useful functions, such as diagnostic testing in lab-on-a-chip sensors, micropatterning surfaces or repairing equipment in tight spaces. But first, scientists need to be able to tightly ...

Gaining more control over fuel cell membranes

More organization at the molecular level could improve the efficiency of membranes used in the hydrogen fuel cells that provide energy to electric cars and other industrial applications, according to a review published in ...
