H2is a symmetric molecule with no direct impact on infrared radiation at temperature and pressure conditions prevailing in the Earth’s atmosphere9. However, hydrogen is recognized as an indirect greenhouse gas through its involvement in chemical reactions which affect the lifetime and concentration of...
However, this process requires the accurate prediction of the solubility of hydrogen in aqueous solutions, which is affected by a range of factors, including temperature, pressure, and the presence of solutes. The present study thus aimed to effectively predict the solubility of hydrogen in aqueous...
2017. By increasing the pressure from 2 to 7.38 MPa (transition to supercritical), the contact angle values increased strongly. But after that, according to the error values, it can be said that the contact angle remains constant. All samples had strongly water-wet behavior at all pressures...

Biological production through microbial processes operates at normal temperature and pressure. It brings several advantages but the low yield is its downside. As shown in Fig. 11.6, biochemical-hydrogen can be produced through different routes such as Dark-fermentation (anaerobic), photo-fermentation (...
The evaporation (heat supply at constant temperature) has to be differentiated from sensible heating (heat supply at varying temperature). For isobaric evaporation, the maximally obtainable work and specific heats involved are then simply determined with the pressure dependent vaporization enthalpy\(h_{...
