Optimization of contact angle and interfacial tension measurements for fluid/rock systems at ambient conditions

open access: yesMethodsX, 2019
Quantification of interfacial tension (IFT) and contact angles is essential to characterize reservoir fluid-fluid and rock-fluid interactions. However, these measurements are highly dependent on chemical structure, surface residues, system conditions ...

Molecular dynamics simulations of interfacial properties of shale oil-CO2, CH4, N2 mixtures

open access: yesYouqi dizhi yu caishoulu
Oil-gas interfacial tension is an important parameter for analyzing the mixing degree of oil and gas phases and influencing the minimum mixing pressure of oil and gas and the development effect of gas injection during gas flooding for enhanced oil ...

Interfacial tension of electrolyte solutions [PDF]

open access: yesThe Journal of Chemical Physics, 2000
A theory is presented to account for the increase in surface tension of water in the presence of electrolyte. Unlike the original “grand-canonical” calculation of Onsager and Samaras, which relied on the Gibbs adsorption isotherm and led to a result which could only be expressed as an infinite series, our approach is “canonical” and produces an ...

Surface and interfacial properties of Fe-C-O-Cr alloys in contact with alumina [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2020
In this paper, temperature and concentration dependencies on density and surface tension of liquid Fe-C-O-Cr alloys (1.93 - 4.80 wt.% Cr) were investigated in high-temperature resistance observation furnace by a sessile drop method during heating from ...

The Importance of Interfacial Tension in Emulsification: Connecting Scaling Relations Used in Large Scale Preparation with Microfluidic Measurement Methods

open access: yesChemEngineering, 2020
This paper starts with short descriptions of emulsion preparation methods used at large and smaller scales. We give scaling relations as they are generally used, and focus on the central role that interfacial tension plays in these relations.

Biophysical approaches for studying viral entry

open access: yesFEBS Letters, EarlyView.
Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Optical Deformation of Emulsion Droplets [PDF]

open access: yes, 2010
Optical tweezers are a useful and fascinating tool for the manipulation of a range of microscopic particles. I describe the set up of optical trapping apparatus, and investigate the use of a spatial light modulator for the creation of arrays of optical ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Surface functionalization of silica nanoparticles to improve the performance of water flooding in oil wet reservoirs

open access: yesEnergy Exploration & Exploitation, 2017
Over the past few years, increasing attention has been devoted to the applications of special engineered nanoparticles in enhancing oil recovery. Earlier studies reported the effects of these particles on wettability alteration of reservoir rock.
