Many people are optimistic about ammonia’s potential as an energy source and carrier of hydrogen, and though large-scale adoption would require major changes to the way it is currently manufactured, ammonia does have a number of advantages. For one thing, ammonia is energy-dense and carbon-free. It is also already producedContinue Reading
A number of advanced energy technologies — including fuel cells, electrolyzers, and an emerging class of low-power electronics — use protons as the key charge carrier. Whether or not these devices will be widely adopted hinges, in part, on how efficiently they can move protons. One class of materials knownContinue Reading
Life may have started in sticky, rock-hugging gels rather than inside cells. Researchers suggest these primitive, biofilm-like materials could trap and concentrate molecules, giving early chemistry a protected space to grow more complex. Within these gels, the first hints of metabolism and self-replication may have emerged., Read MoreContinue Reading
