Brine fluids have recently been of high interest to enhanced oil recovery process in both academia and industry. Both diluted formation brines specifically formulated were reported improve crude displacement porous rock, owing either their bulk salinity or brine-type. Mechanisms for such an improvement widely proposed, including microscopic interfacial phenomena: wettability alteration reductio...

Controlling the wettability of a solid surface is important for myriad applications, ranging from self-cleaning surfaces to microfluidics to biomedicine. Recently, a variety of smart surfaces with reversibly switchable wettability have been developed. The reversible switching is realized through the adjustment of electrical potential, temperature, 8] and light illumination, adsorption of biopol...

The study investigated the effects of short-term thermo-mechanical (STTM) densification temperature and pressure on changes in surface wettability of alder (Alnus glutinosa), beech (Fagus sylvatica), birch (Betula verrucosa) and pine (Pinus sylvestris) wood veneer. Veneer sheets were densified using pressure levels of 4 MPa, 8 MPa and 12 MPa at three temperatures: 100°C, 150°C and 200°C for a s...

The current laboratory study is evaluating the effect of hydrofluoric acid etching duration on the surface characteristics of five silica-based glass ceramics. Changes in the pore pattern, crystal structure, roughness, and wettability were compared and evaluated. Seventy-five rectangularly shaped specimens were cut from each material (IPS e-max™, Dentsply Celtra™, Vita Suprinity™, Vita mark II™...

For obtaining good joints by soldering, a wettability of liquid metal on the solid metal surface, relatlatte, relattlated o solderability, is one of the most important factors, and the wettability is accelerated by using a suitable flux and atmosphere. In atmosphere soldering the flow of molten solder will be retarded by oxide films on base metals formed by a small amount of oxygen in atmospher...

A method has been developed to infer the wettability of steam-water-rock systems based on the relationship between permeability and capillary pressure by Purcell. The Purcell model was extended to two-phase flow to verify whether the wettability is a function of water saturation. The results calculated using the experimental data showed that the wettability index in the drainage process was gre...

Polydimethylsiloxane (PDMS) is an appealing silicone elastomer as a base material for microfluidic biomedical applications. Its ability to easily ross-link as well as its favorable physical and chemical properties has enabled a large number of microand nano-cast applications. However, DMS’ hydrophobic surface can be problematic. Two methods presented here address the wettability of PDMS by accu...
