61. Elasticity of Liquid Nitrogen in Nanoporous Vycor Glass

Dr Klaus Schappert (Universität des Saarlandes, Department of Physics)

(MS13) Fluids in Nanoporous Media

Oral Presentation

Experimental and theoretical research has shown that several factors influence the elastic properties of fluids confined in nanopores [1,2]. Previous experimental studies on the longitudinal modulus of confined fluids were mostly limited to the adsorbate argon. Here we study the longitudinal modulus of liquid nitrogen in the nanopores of Vycor glass at various temperatures using ultrasonic...

408. A New Precise Correlation for Permeability Estimation of Tight Carbonate Rocks Using Mercury Intrusion Porosimetry (MIP) Data

(MS13) Fluids in Nanoporous Media

Oral Presentation

There has been a long-standing concern with the estimation of permeability, particularly in tight carbonate reservoirs. So far, scholars have proposed several empirical correlations for permeability assessment, but the need for a correlation to provide reliable predictions for tight carbonate reservoirs is still felt. In this study, we aim to present a correlation for permeability estimation,...

432. Impact of salt on sorption isotherms of water in nanoporous media

HUGO BELLEZZA

(MS13) Fluids in Nanoporous Media

Oral Presentation

Salt water is ubiquitous in nature (e.g. geomaterials, soil, clouds formation) and in technology (e.g. desalination, concrete weathering, heritage conservation). In most of these situations, salt water is confined within a porous medium, often with pores down to the nanometer scale: for example, crystallization and dissolution cycles induced by humidity changes are known to induce structural...

40. Extension of the SAFT equation of state to capture the effect of the solid wall into the confined fluid properties: using molecular dynamic simulation

Mr Sajjad Ahmadigoltapeh (University of Oslo)

31/05/2022, 17:15

(MS13) Fluids in Nanoporous Media

Oral Presentation

The thermodynamic characteristics of water confined inside a nano-mineral pore differs from the bulk properties because of the competition between water-water and wall-water attractions near the solid walls. We used molecular dynamic (MD) simulation, to capture the influence of the solid walls of a slit shape calcite nanopore on the confined water provided in different widths namely 2 nm, 3...

263. Confined phase behavior of a CH4-CO2 binary system: molecular simulations, equation of state, and lattice Boltzmann method

Lingfu Liu (University of Wyoming)

31/05/2022, 17:30

(MS13) Fluids in Nanoporous Media

Oral Presentation

Phase behavior of confined fluids may deviate significantly from that of the bulk fluid due to the fluid-walls interactions being a significant portion of all intermolecular interactions under confinement. There are recent advancements in understanding confined phase behavior of pure species, confined phase behavior of mixtures remains an understudied topic. In this work, we examine the...

57. Molecules diffusing and relaxing in macro, meso and microporous materials: An NMR approach for studying the behaviour of fluids confined in nanoporous media

Dr Carmine D'Agostino (The University of Manchester)

31/05/2022, 17:45

(MS13) Fluids in Nanoporous Media

Oral Presentation

Transport and dynamics of fluids in nanoporous networks play a significant role in many applications of porous materials, most notably catalysis, separation and adsorption technologies. Yet, direct experimental measurements of such phenomena at a pore-scale/microscopic level is challenging and key parameters such as diffusion or adsorption coefficients are often extrapolated using indirect...

411. Electrochemical Actuation in Nanoporous Silicon

manuel Brinker (Hamburg University of Technology)

01/06/2022, 16:00

(MS13) Fluids in Nanoporous Media

Oral Presentation

Porous silicon provides a scaffold structure to study the confinement related effects of soft matter. We investigate the electro-sorption of electrolyte anions and the electrochemical behaviour of nanoporous silicon in acidic electrolytes. The silicon-electrolyte interface acts as a capacitor which allows the accumulation of electrolyte anions in a chemical double layer by an applied voltage,...

563. Molecular Transport in Nanoporous Gold Thin Films for Drug Delivery Applications

Prof. Erkin Seker (University of California, Davis)

01/06/2022, 16:15

(MS13) Fluids in Nanoporous Media

Oral Presentation

Nanoporous materials have been commonly utilized in drug delivery platforms due to their large specific surface area for higher loading capacity and tunable morphology for controlling drug release profile. In these platforms with large surface area, the interfacial phenomena (surface-molecule interactions) play a significant role in dictating loading capacity and release kinetics. In a...

384. Operando Determination of Pore-filling Mechanism and Saturation of PEFC Catalyst Layer using Small-Angle X-ray Scattering

Kinanti Hantiyana Aliyah (Paul Scherrer Institut)

01/06/2022, 16:30

(MS13) Fluids in Nanoporous Media

Oral Presentation

Shortcomings in the water management of polymer electrolyte fuel cells (PEFC) need to be overcome for successful market penetration. Proper membrane humidification relies on ionomer hydration, which in turn affects the performance. In contrast, excess water retention in the pores results in blockage of the gas diffusion to the active sites of the electrochemical reaction, thus reducing...

52. Water transfers (imbibition, drying) in cementitious materials followed by MRI (Magnetic Resonance Imaging)

Hicham DIALLA (Lab. Navier, Univ Gustave Eiffel / CEA, DES, ISEC, DMRC, Univ Montpellier, Marcoule, France)

01/06/2022, 16:45

(MS13) Fluids in Nanoporous Media

Oral Presentation

Nowadays, cement-based materials are widely used, whether in construction or even in the conditioning of radioactive waste. However, the performance of these materials could be substantially affected by the penetration of water. Indeed, the infiltration of water facilitate the ingression of aggressive agents such as Cl, CO2, etc. and can cause many types of degradation such as chloride...

465. Water confined in salt crusts: insights from molecular simulations

Simon Gravelle (Institute for Computational Physics)

02/06/2022, 09:10

(MS13) Fluids in Nanoporous Media

Oral Presentation

The evaporation of water from a bare soil can be accompanied by the formation of a layer of crystallized salt. This salt crust forms an additional porous layer that affects the evaporation of water in a counter-intuitive way: depending on the conditions (i.e. depending on the pore size of the crust, soil-crust connection, external atmospheric conditions), the crust can hinder or enhance the...

93. Gas Flow Simulation in Multiscale and Multimineral Digital Rocks of Shale Samples

Yuqi Wu

02/06/2022, 09:25

(MS13) Fluids in Nanoporous Media

Oral Presentation

The exploration and development of shale gas require accurate characterization of shale samples and modeling of gas flow. Digital rocks have been widely used to characterize the shale samples, predict their petrophysical properties, and understand the pore-scale transport mechanisms in micrometer and nanometer pore systems. Previous studies from numerous geologists have indicated that the...

510. Pore networks meet computational chemistry: a hybrid approach for studying the flow of fluid mixtures under various thermodynamic conditions in nanoporous materials.

Aleksey Khlyupin (Moscow Institute of Physics and Technology)

02/06/2022, 09:40

(MS13) Fluids in Nanoporous Media

Oral Presentation

An unconventional reservoir is a multiscale system in which pores with the size of several nanometers can reach 80% of the total pore volume. [1]. Traditional methods of production processes modeling based on the Navier-Stokes equation, which describes the behavior of a continuous medium, are not suitable for this case, since they do not consider the molecular interactions of fluid and rock....

229. Effect of osmosis on spontaneous imbibition of fracturing fluid in shale oil formation

Dr Qinghao Sun (China University of Petroleum (East China))

02/06/2022, 09:55

(MS13) Fluids in Nanoporous Media

Oral Presentation

The traditional theory of spontaneous imbibition is fluid displacement caused by capillary force. However, the imbibition of fracturing fluid in shale reservoir is not only related to capillary force, but also affected by osmotic pressure. Shale pores are in micro/nano scale and have high clay content. Clay is mainly distributed on the pore wall, and can act as a semi-permeable membrane when...
