Haber-Bosch at the atomic scale

Industrial production of NH3 has been performed by the Haber-Bosch process for more than 100 years, in which dissociation of N2 feedstock molecules promoted by alkali atom co-catalyst is thought to be the rate limiting step. ...

Without helpful microbes, tadpoles can't stand the heat

In a warming world, animals could live or die by what's in their gut. That's one conclusion of a new study by Pitt biologists showing that tadpoles are less able to cope with hot temperatures without the help of microbes. ...
