A new measurement could change our understanding of the universe
The universe is expanding, but how fast exactly? The answer appears to depend on whether you estimate the cosmic expansion rate—referred to as the Hubble's constant, or H0—based on the echo of the Big Bang (the cosmic microwave background, or CMB.....»»
Low-temperature ammonia-to-hydrogen conversion achieved by applying an electric field
Hydrogen gas, owing to its high energy density and carbon-free nature, is gaining much attention as the energy source for a green and sustainable future. Despite being the most abundant element in the universe, hydrogen is mostly found in a bound sta.....»»
Quantum sensing approach captures nanoscale electrochemical evolution in battery
