Abstract (sommario):

Despite many excellent properties of wood which make it suitable for many applications, it suffers from a number of disadvantages limiting its use. For instance, modification is needed to reduce water sorption and to improve decay resistance, dimensional stability and weathering performance. In addition, wood/liquid interaction such as water wettability on wood plays an important role in design and characteristics of many processes and phenomena such as adhesion, coating, waterproofing, wood chemical modification, and weathering. This thesis focuses on enhancing the understanding of wetting of

Abstract (sommario):

This project aims at the fabrication of a rough polydimethylsiloxane(PDMS) surface with patterned smooth areas. The idea is that such a surface will allow for water capturing on the smooth areas of the surface. The applications for this kind of surface are many, but especially the prospects of a surface able to trap droplets of cells in suspension by simply dipping the surface into the suspension is intriguing.From a previous project[1], and another students masters thesis[2], the use of an etched copper surface seemed promising for the fabrication of a rough mold.

Abstract (sommario):

Nuclear Magnetic Relaxation Dispersion (NMRD) is strongly sensitive to the microscopic wettability of oil and brine bearing carbonate rocks. Exploring a very large range of low frequency enables isolating the typical NMRD dispersion features, 1/T1Surf, associated to the different processes of molecular surface dynamics. This allows a separation of the surface and bulk microdynamics of oil and water even for a biphasic saturation of petroleum rocks. Several surface dynamical parameters were determined and related to the concept of microscopic wettability of oil and water in porous media.

Abstract (sommario):

In this study, a surface with patterned wettability by means of surface structuring, rather than through modifying the surface chemistry, was developed. The device presented in this thesis was inspired by the Namib Desert Bettle, which collects water from the fog by having hydrophilic spots surrounded by hydrophobic wax-coated regions on its back. Besides water collection, controlling the wetting behaviour locally on the surface may find applications within droplet-based microfluidics, or fabrication of DNA, protein or cell microarrays. Spatial wetting contrast was achieved through replica mou

Abstract (sommario):

The surface charge of carbonate minerals, which is also expressed in terms of the zeta potential, plays a key control on reservoir wettability, and changes in the zeta potential have been invoked to explain wettability alteration and the release of previously trapped oil during controlled salinity waterflooding (CSW). We report a method to characterize the zeta potential of carbonates, based on measurements of streaming potential, which can be used to determine the zeta potential of mineral-brine and oil-brine interfaces within the porous medium. The aim of this project was to determine the ef

Abstract (sommario):

Brazilian Pre-Salt carbonate reservoirs have been one of the greatest oil discoveries of the past decade. In fields such as Lula, it is expected to recover between five to eight billion barrels of oil equivalent. To fulfill this, knowledge of reservoir wettability is fundamental, given that it dictates how fluids (water, oil and, gas) are distributed within the porous media, and how the multiphase flow occurs in the pore-network. This information is important in the construction of relative permeability curves which are input for reservoir simulators. Few works have been published regarding in

Abstract (sommario):

Wetting of a substance has been widely investigated since it has many applications to many different fields. Wetting principles can be applied to better select cleans for front end of line (FEOL) and back end of line (BEOL) cleaning processes. These principles can also be used to help determine processes that best repel water from a semiconductor device. It is known that the value of the dielectric constant in an insulator increases when water is absorbed. These contact angle experiments will determine which processes can eliminate water absorption. Wetting is measured by the contact angle bet

Abstract (sommario):

In this thesis, acoustics measurement is used to estimate the wettability of the formation rock. The wettability effect on the wave propagation in the saturated porous media is studied by applying the slip boundary condition (SBC), which plays an important role in the wave-induced-fluid-flow (WIFF). The wettability dependent wave velocity and attenuation are studied theoretically and experimentally. A practical method is developed to estimate the wettability of the formation rock by the acoustics measurement.

In general, combinations of wood and polymers especially in outdoor exposure have poor long-term durability. This behaviour can be related to an insufficient wood-polymer adhesion due to the low intrinsic compatibility between the wood substance and the polymers used. Another source for woodpolymer de-bonding is the high hygroscopicity of wood and great difference in hygro-thermal properties between the components.</p><p> The basic conceptual idea related to this work is to reduce the hygrosensitivit

Abstract (sommario):

Reservoir wettability is controlled by crude oil/brine/rock interactions that have not been well understood. Studies using either model compounds or crude oil fractions have had only limited success in reproducing the wetting alteration that can occur in nature. In this study, the approach is first to identify the key features of interfacial activity unique to crude oils, then to design and conduct wetting alteration experiments—using both flat solids and porous media—that demonstrate the mechanisms by which alteration can occur. Components of crude oils that are interfacially active are found

By changing the deposition time from 10 to 90 min., the diameter, height, and separation of the nanorods were varied.

Abstract (sommario):

While carbonate reservoirs are recognized to be weakly- to moderately oil-wet at the core-scale, wettability distributions at the pore-scale remain poorly understood. In particular, the wetting state of micropores (pores < 5 μm in radius) is crucial for assessing multi-phase flow processes, as microporosity can determine overall pore-space connectivity. Nonetheless, micropores are usually assumed to be water-wet and their role in multi-phase flow has often been neglected. However, oil-wet conditions in micropores are plausible, since oil has been detected within micropores in carbonate rocks.

Furthermore, the permeability of sandstone samples reduced after injection of brine, CO2-saturated brine or supercritical CO2 at reservoir conditions.

Abstract (sommario):

Low salinity waterflooding appears to be a cost-effective and environmentally friendly means to improve oil recovery by increasing hydrophilicity. However, the controlling factor(s) behind this process remains unclear. This research characterized wettability of oil-brine-rock system from nano to pore scale through a combination of experiments and geochemical modelling, providing insights to better model multiphase flow at subsurface. New findings can also help to constrain the intrinsic uncertainties of CO2-assisted EOR with respect to wettability alteration.

Abstract (sommario):

The focus of this research is to investigate the influence of rock wettability on CO2 movement through porous media. By performing different multiphase flow reservoir simulations on a hectometre scale, this research investigates the effects of wettability, wettability spatial distribution, and factors affecting wettability on the efficiency of CO2 trapping mechanisms. The results of this research show that reservoir wettability significantly influences CO2 storage efficiency and that water-wet reservoirs are preferable CO2 sinks.

Abstract (sommario):

The field of wettability is an age-old topic that has been revitalized in the last two decades. Historically, the diverse physical phenomena of wetting has influenced the development of inventions that dates back to the paleolithic era (2,600,000 to 10,000 BC) in the form of charcoal and ochre -based cave paintings, or the mesolithic (10,000 to 5,000 BC) and neolithic (5,000 to 2,000 BC) periods as pottery and soaps. Since the end of the Stone Age, human civilizations and scientific discoveries have progressed by leaps and bounds. Despite the advances in
