One of the challenges in storing hydrogen gas in aqueous solutions is estimating its solubility in water. In this study, after collecting experimental data from previous research and eliminating four outliers, nine machine learning methods were developed to estimate the solubility of hydrogen in water...

Similar to natural gas extraction, drilling remains the primary method of natural hydrogen production. Natural hydrogen reservoirs are confined by impermeable layers and can be accessed by drilling a well. Hydrogen originates from reactions between shallow iron-rich formations and thermal underground wate...
The vertically aligned SWNTs became rearranged into a wall-like architecture after immersing in water. Hydrogenase was spontaneously incorporated within the SWNT-forest and confined on the sidewall of the rearranged architecture. The SWNT-forest was a very stable protein carrier in aqueous solution,...
Solubility: Soluble in water and oil: solubility decreases as the fluid temperature increases Combustibility: Burns with a blue flame to produce sulfur dioxide (SO2). Odor and Warning Properties: Hydrogen sulfide has an extremely unpleasant odor, characteristic of rotten eggs, and is easily detected...

The hydrogen solubility in metals is extremely high, and the adsorption of hydrogen in steel may pose embrittlement that may lead to the failure of equipment. Hydrogen is 14 times lighter than air and approximately 57 times lighter than gasoline (Fig. 1.9), which means it will be immediately ...
Atoms start behaving as waves rather than classical particles if confined in spaces commensurate with their de Broglie wavelength. At room temperature this length is only about one ångström even for the lightest atom, hydrogen. This restricts quantum-confinement phenomena for atomic species to ...
