Synthesis and characterization of a highly hydrophilic nanocomposite for wettability alteration, water/oil interfacial tension reduction, and enhanced oil recovery

The Canadian Journal of Chemical Engineering, EarlyView.
Mechanism of wettability alteration, interfacial tension reduction, and oil recovery by novel nanocomposite. Abstract The development of stable nanofluids (NFs) for enhanced oil recovery (EOR) relies on optimizing interactions between reservoir rocks and fluids.

A Simulation Study of Inhibition Assay With Theophylline on the Enzymatic Hydrolysis of p‐Nitrophenyl Phosphate With Alkaline Phosphatase in a Continuous Mode of Electrophoretically Mediated Microanalysis

ELECTROPHORESIS, EarlyView.
Inhibition assays in in‐capillary continuous enzymatic reaction were simulated using a MATLAB matrix. The enzymatic hydrolysis of p‐nitrophenyl phosphate (S) with alkaline phosphatase (ALP) was adopted as a model enzymatic reaction, where theophylline (I) was used as a model inhibitor.

Effects of surface charge and boundary slip on time-periodic pressure-driven flow and electrokinetic energy conversion in a nanotube

Beilstein Journal of Nanotechnology, 2019
Time-periodic pressure-driven slip flow and electrokinetic energy conversion efficiency in a nanotube are studied analytically. The slip length depends on the surface charge density.

Cyclodextrins as Chiral Selectors in Capillary Electrophoresis—Recent Developments in Understanding Analyte Complexation and Applications in Pharmaceutical Analysis

ELECTROPHORESIS, EarlyView.
Cyclodextrins are the most often applied chiral selectors in CE enantioseparations. In combination with NMR spectroscopy and molecular modeling, studies for an understanding of chiral recognition underlying enantioseparations have been performed.

An Optofluidic Young Interferometer for Electrokinetic Transport-Coupled Biosensing

Micromachines
Label-free optical biosensors, such as interferometers, can provide a comparable limit of detection to widely used enzyme-linked immunosorbent assays while minimizing the number of steps and reducing false positives/negatives.

Optimisation of Electrokinetic Extraction System: Colourimetric Determination of Copper (II) in Sand Using Polymer Inclusion Membrane

ELECTROPHORESIS, EarlyView.
Electrokinetic extraction (EKE) allows the direct transfer of heavy metals from soli samples, such as soil and sediment, into a polymer inclusion membrane (PIM) with a colourimetric detection. This avoids length and complex sampling handling and extraction processes.

Electrokinetic instability in microchannels

Physical Review E, 2012
The effect of geometric confinement on electroconvective instability due to nonequilibrium electro-osmotic slip at the interface of an electrolytic fluid and charge-selective solid is studied. It is shown that the topology of the marginal stability curves and the behavior of the critical parameters depend strongly on both channel geometry and ...

Protein‐Based High‐Performance Liquid Chromatography and Cyclodextrin‐Capillary Electrokinetic Chromatography for the Chiral Separation of Azoles

ELECTROPHORESIS, EarlyView.
Human serum albumin‐based high‐performance liquid chromatography and cyclodextrin‐based capillary electrokinetic chromatography were used for the chiral separation of azoles. Although only two of the five tested azoles could be enantioseparated by liquid chromatography, all of them were separated by capillary electrokinetic chromatography using single ...
