A methane-powered vehicle can utilize methane which is stored as the fuel in a pressurizable tank containing a solid filling which enables a packing density of methane in adsorbed or otherwise trapped form to exceed 10 times the density of the methane at room temperature and a pressure of ...
No need for a metal: A combination of mass spectrometry and computational studies (density functional theory and coupled-cluster methods) shows that [P4O10].+ is the first polynuclear nonmetal oxide cation that is capable of activating the CH bond of methane at room temperature (see picture)....
A methane-powered vehicle can utilize methane which is stored as the fuel in a pressurizable tank containing a solid filling which enables a packing density of methane in adsorbed or otherwise trapped form to exceed 10 times the density of the methane at room temperature and a pressure of abo...
Methane (CH₄) is a colorless, odorless gas at room temperature and pressure. It is highly flammable and is the simplest alkane, consisting of one carbon atom bonded to four hydrogen atoms. Methane was first identified in 1776 by Alessandro Volta, who isolated it from marsh gas. Later, ...

During the plasma-assisted DRM process, the plasma itself generates excited molecules, atoms, atomic and molecular ions, as well as metastable species at room temperature. These species recombine to form neutral molecules, react with them, and form fine chemicals. The mechanisms of CH4 and CO2 ...
(λ > 300 nm) operated at room temperature, together with a long stability of over 112 hours. The nanoalloy works as a hole acceptor, in which Pd softens and weakens C-H bond in methane and Cu decreases the adsorption energy of C2products, leading to the high efficiency and ...
The hydrogen volumetric density of methanol at room temperature (98.9 kg-H2/m3) is larger than that of LH2 at 20 K (70.8 kg-H2/m3), and together with ammonia, have amongst the highest volumetric and gravimetric hydrogen storage density compared to other carriers [42]. In addition, ...
