(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 ...
Researchers at Princeton University have detected a unique quantum property of an elusive particle notable for behaving simultaneously like matter and antimatter. The particle, known as the Majorana fermion, is prized by ...
