A New Way to Synthesize Hydrocarbons Could Reduce

The conversion normally requires significant amounts of energy in the form of high heat — a temperature of at least 700 degrees Celsius, hot enough to melt aluminum at normal atmospheric pressure. Instead of heat, the team relied on the energy harvested from traveling waves of electrons, known as localized surface plasmons (LSPs), which surf on individual aluminum nanoparticles.
