Suicmez et al. (2008) studied the effects of wettability for water-wet, weakly water-wet, oil-wet, and weakly oil-wet media and pore-level displacement on hydrocarbon trapping, using three-phase-flow pore-scale network modeling.
The poly ether ester)s were stable towards treatment at room temperature with water or weakly acidic or alkaline solutions.
Ammonia water was weakly reactive; however, it could be used to precisely control the pore architecture, and no ion exchange is needed for acid catalysis.
First stage occurred in the temperature range from r.t. to 150 °C, which is due to the loss of water molecules weakly bound to the material.
Most part of the water is weakly retained within gels micropores making these hydrogels an attractive material for biomedical applications including cell scaffolds, matrices for bioreactor systems and for bio-separation processes.
In those studies, the measured pH of water is weakly alkaline (i.e., 8 9) and drops to sub-neutral (i.e., 5 6) when corrected according to the temperature increase with depth.
Water adheres weakly to wax and strongly to itself, so water clusters into drops.
Ammonia in water reacts weakly alkaline as it binds the hydrogen ion.
