There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability ...
A nanoporous material that holds hydrogen at twice the density of cryogenic liquid H2 could address the challenges of large-scale liquid and gas storage that have held this clean fuel back. Hydrogen ...
A German-US research team has shown that hydrogen condenses on smooth surfaces at a very low temperature, forming a super-dense monolayer that reduces the volume to just 5 liters per kilogram of H2.
