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 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 ...
Liquid: stop or reduce leak if safe to do so. If not, allow liquid to vapourize. Ventilate the area to prevent the gas from accumulating, especially in confined spaces. Gas: stop or reduce leak if safe to do so. Ventilate the area to prevent the gas from accumulating, especially in co...

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,...

However, it is notable that the solubility of hydrogen in pure water is relatively low, approximately 0.00016 mmol/L at 25 °C and 0.1 MPa (Lv et al., 2024), in contrast to other gases, such as CO2, which exhibits a much higher solubility of around 1.45 mmol/L under similar ...
[Zn (OAc)2 (dmae)2] (I) having low decomposition temperature besides excellent solubility in organic solvents makes it a perfect precursor for producing ZnO thin films. The structural analysis confirmed the growth of crystalline and single-phase ZnO thin film. The morphological analysis confirmed ...
