چکیده

As a liquid moves in the nanopores of a silica gel, because of the hysteresis of sorption behavior, significant energy dissipation can take place. Through a calometric measurement, the characteristics of associated heat generation are investigated. The temperature variation increases with the mass of silica gel, which consists of a reversible part and an irreversible part. The residual temperature change is about 30% to 60% of the maximum temperature increase and can be accumulated as multiple loading cycles are applied.

Effects of the addition of electrolyte on liquid infiltration in a hydrophobic nanoporous silica gel.

In this letter, we report the experimental results of pressure induced infiltration in the hydrophobic nanopores of a silica gel. The infiltration pressure increases with the prolonged surface treatment time, whereas the infiltration volume is not dependent on the surface coverage. When temperature increases, if the liquid phase is pure water, the infiltration pressure would decrease, which is ...

Effects of decomposition-treatment temperature on infiltration pressure of a surface modified nanoporous silica gel

When a nanoporous silica gel surface modified by silyl groups is decomposition-treated at a relatively low temperature, while the network is stable, the organic surface layers can be deactivated. As a result, the degree of hydrophobicity, which can be measured by the liquid infiltration pressure, is lowered. The infiltration and defiltration behaviors of liquid are dependent on the controlled d...

Pressure-induced infiltration of aqueous solutions of multiple promoters in a nanoporous silica.

By applying an external pressure, an aqueous solution of promoters can be forced into a hydrophobic nanoporous silica gel. The promoter molecule demands a free volume several times larger than itself to enter the nanoenvironment. The free volume size is a function of the promoter concentration. If more than one promoter is used, the system behavior does not follow the principle of superposition...
