Under certain low-temperature and high-pressure conditions, these two substances will form a solid, ice-like compound. Gas hydrates are crystalline compounds that result from the three-dimensional (3D) stacking
Within one molecule, coupling can occur between the stretch modes of the two O–H groups8, and strong intermolecular coupling of stretch modes makes its excitation quasi-instantaneously delocalized across several molecules in liquid water. The stretch modes are further coupled to the bending mode ...
During water/gas injection scenarios, asphaltene may accumulate at the liquid–liquid and solid–liquid interfaces and form microemulsions (due to interfacial tension (IFT) reduction)24and alter the wettability of solid surfaces, respectively. Yet, the mechanisms of these two phenomena through asphaltene...
Liquid water is an integral element of life, as it is the major component of every cell. Water acts as a passive but native matrix that solvates a myriad of biological molecules and ions and hosts an intricate network of communication among them. It is now clear that water also exhibits an...
Water is thus one of the very few substances whose solid form has a lower density than the liquid at the freezing point. Localized clusters of hydrogen bonds still remain, however; these are continually breaking and reforming as the thermal motions jiggle and shove the individual molecules. As ...
We note three limitations of this model. First, it assumes that molecular-kinetic diffusion is unaffected by the dimensions of the pore structure, specifically that the mean free path of water molecules in air,\(\lambda\), is smaller than the length scale of the porosity\(\Lambda\): that ...
solubility at both high and low temperatures. Pressure rise causes compressibility in the gas phase, which leads to the release of more space for additional gas molecules to be dissolved in the water. In Fig.9a, the solubility at 278 K was higher than that of 304.19 K. Although, in high...
Understanding redox and photochemical reactions in aqueous environments requires a precise knowledge of the ionization potential and electron affinity of liquid water. The former has been measured, but not the latter. We predict the electron affinity of
The biliquid nanofoam structure with 10 2 –10 4 oil molecules enclosed by locally flat layers of interdigitated hydrated headgroups exists in the middle of the phase diagram. We may speculate that this phase can be used as a multitude of nanocontainers, e.g., for chemical reactions in ...
The low concentrations of double-tail molecules and fatty acids in polyglycerol esters affect considerably their micellar, aggregation, and vesicle formations in aqueous solutions. The theoretical data interpretation of polyglycerol esters isotherms and thin liquid films data provide information on the adsorp...
