(Phys.org)—Paul Chirik, a chemistry professor at Princeton University has, according to a profile in the New York Times, developed a process that allows ordinary iron to be used as a substitute catalyst in certain reactions ...
(Phys.org)—Platinum works well as a catalyst in hydrogen fuel cells, but it has at least two drawbacks: It is expensive, and it degrades over time. Brown chemists have engineered a cheaper and more durable catalyst using ...
