The phenomenon of capillary condensation is studied through the weight change of condensed phase in an internally wetted porous pd catalyst pellet during the course of exothermic reacation of cyclohexane hydrogenation in a thermogravimetric analyzer (TGA). The direct measurement of condensed phase indicates that evaporation of condensed phase is confined to the macropores of catalyst pellet at ...

In oil reservoirs, if mainly has wettability in the solid phase, such as carbonate medium is oil-wetted. For oil-wetted porous media containing an and water two-phase flow, there are electric double layers at both oil–solid interface oil–water interface, which can stimulate seismoelectric effect. To date, most of studies on effects have focused water-wetted media, however, few reported cases es...

Litchi (Litchi chinensis Sonn.) is an important subtropical evergreen fruit crop of Sapindaceae family. Fruit cracking a serious problem in litchi happen during growth and its development. affect significant loss economic yield. coincides with period characterized by high day temperature (35-40°C) low relative humidity (60%). Effect water sprinkling over tree canopy on cracking, quality yield w...

Weakly ferromagnetic cobalt nanoparticles can assemble spontaneously into nanosized "bracelets" when dispersed in organic solvents containing resorcinarenes as surfactants. Bracelet self-assembly occurs in solution and is directed by magnetic dipolar interactions, whereas nanoparticle rings with larger diameters are produced by evaporation-driven flow on wetted surfaces.

We consider the phase separation of binary fluids in contact with a surface, which is preferentially wetted by one of the components of the mixture. We review the results available for this problem and present numerical results obtained using a mesoscopic level simulation technique for the three-dimensional problem.

We designed a kind of smart bioinspired fiber using the N-isopropylacrylamide (NIPAAm) polymer, with roughness and curvature features similar to those of wetted spider silk. The motion of tiny water droplets can be manipulated reversibly in directions by the effective cooperation of multi-gradients such as roughness, curvature and temperature-responsive wettability.

optimal use of water resources is essential to decrease cost and maximize available water resources. subsurface drip irrigation can increase irrigation and water use efficiency. this irrigation method distributes water into the soil, leaving the surface of the soil dry and decreasing evaporation. in the design of subsurface drip irrigation (sdi) systems, the dimensions of the wetted onion deter...
