Novel insights into the geochemical evaluation of polymer drive composition on surfactant retention in carbonates using the surface complexation modeling [PDF]

open access: yesScientific Reports, 2022
Surfactant-polymer (SP) flooding is considered an efficient technique to increase the recovery of oil, especially from carbonates reservoirs, because of their complex nature.

Complexation of DNA with Thermoresponsive Charged Microgels: Role of Swelling State and Electrostatics

open access: yesGels, 2022
Micro- and nanogels are being increasingly used to encapsulate bioactive compounds. Their soft structure allows large loading capacity while their stimuli responsiveness makes them extremely versatile.

Efficient and Rapid Removal of Pb(II) and Cu(II) Heavy Metals from Aqueous Solutions by MgO Nanorods

open access: yesInorganics, 2022
In this study, the adsorption capability of MgO nanorods for the quick and effective elimination of Cu(II) and Pb(II) heavy metals from wastewater was examined. The MgO nanorods were produced via simple coprecipitation process.

Antimony (V) Adsorption at the Hematite–Water Interface: A Macroscopic and In Situ ATR-FTIR Study

open access: yesSoil Systems, 2021
The environmental mobility of antimony (Sb) is largely unexplored in geochemical environments. Iron oxide minerals are considered major sinks for Sb. Among the different oxidation states of Sb, (+) V is found more commonly in a wide redox range.

A literature review on thermodynamic sorption models of radionuclides with some selected granitic minerals

open access: yesFrontiers in Nuclear Engineering, 2023
The literature for radionuclide sorption on four common granitic minerals have been surveyed. Mainly, such studies were modelling using Thermodynamic Sorption Models were investigated. Although the studies give a far from concerted results, they agree on

Sorption of Pd on illite, MX-80 bentonite and shale in Na–Ca–Cl solutions

open access: yesNuclear Engineering and Technology, 2021
This paper examines sorption of Pd(II) onto illite, MX-80 bentonite, and Queenston shale in Na–Ca–Cl solutions of varying ionic strength (IS) from 0.01 to 6.0 mol/L (M) and pHc ranging from 3 to 9 under atmospheric conditions.

Complex fluids at complex surfaces: simply complicated? [PDF]

open access: yesMolecular Physics, 2011
We study wetting and filling of patterned surfaces by a nematic liquid crystal. We focus on three important classes of periodic surfaces: triangular, sinusoidal and rectangular. The results highlight the similarities and differences of nematic wetting of these surfaces and wetting by simple fluids.

Revealing unconventional host–guest complexation at nanostructured interface by surface-enhanced Raman spectroscopy

open access: yesLight: Science & Applications, 2021
Interfacial host–guest complexation offers a versatile way to functionalize nanomaterials. However, the complicated interfacial environment and trace amounts of components present at the interface make the study of interfacial complexation very difficult.

Complexity in Bolza Surface

open access: yes, 2023
Abstract A surface in the Teichmüller space, where the systole function attains its maximum, is called a maximal surface. For genus two there exists a unique maximal surface which is called the Bolza surface. In this article, we study the complexity of the set of systolic geodesics on the Bolza surface.

Determination of intrinsic equilibrium constants at alumina/electrolyte interface [PDF]

open access: yesJournal of the Serbian Chemical Society, 2004
Intrinsic ionization and complexation constants at an alumina/electrolyte interface were studied by the site binding model, while the sorption of alkali cations from aqueous solutions was interpreted by the triple-layer model.
