(Phys.org) —A trio of researchers at California Institute of Technology has developed an iron-based catalyst that allows for reducing dinitrogen (a normal nitrogen molecule with two atoms) to ammonia in a solution. In their ...
(Phys.org)—Plants are able to convert sunlight into energy through photosynthesis. There is much interest in designing a system that mimics the photosynthetic process as an environmentally friendly way to produce energy ...
(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) -- Chemists don't like precious metals – at least not when they need the expensive materials as catalysts to accelerate reactions or guide them in a particular direction. And this is often the case, as in ...
