Cerofolini’s Model and the Fractal Adsorption Isotherms

open access: yesFractal and Fractional, 2023
The close link between the roughness of a surface and its adsorptive properties in Cerofolini’s model yields, with an adequate choice of adsorption energy, the well-known Dubinin-Radushkevich or Freundlich adsorption isotherms.

Adsorption isotherms of charged nanoparticles [PDF]

open access: yesSoft Matter, 2016
We present theory and simulations which allow us to quantitatively calculate the amount of surface adsorption excess of charged nanoparticles onto a charged surface. The theory is very accurate for weakly charged nanoparticles and can be used at physiological concentrations of salt.

Monte Carlo Simulation and Exact Statistical Mechanical Lattice Models as a Development Tool for Zeolite Multi-Component Adsorption Isotherm Derivation

open access: yesAdsorption Science & Technology, 2012
Developing a suitable separation and purification procedure for multi-component gas mixtures is a ubiquitous problem. Very little is known experimentally about multi-component adsorption isotherms, yet these are crucially important for designing ...

Modelling of Single-Gas Adsorption Isotherms

open access: yesMetals, 2022
The present paper reviews and analyses different models that could be used to describe the adsorption equilibrium of pure gases. The adsorption equilibrium of hydrogen, nitrogen and methane is characterised and modelled. Several thermodynamic conceptions

Entropy in multiple equilibria : argon and nitrogen adsorption isotherms of nonporous, microporous, and mesoporous materials [PDF]

open access: yes, 2021
Analysis of multiple equilibria of compounds with different coordination sites is extended to the description of adsorption isotherms with focus on the low relative pressure range. The entropy evolution is described using the particle distribution theory

Protein Adsorbate Biohybrids and Sequential Hystallosteric Protein Adsorption

open access: yesCurrent Directions in Biomedical Engineering, 2021
Protein adsorption on solid surfaces is characterized by multivalence, binding-unit overlap, sequential adsorption, surface allosterics, lateral interactions and pronounced adsorption-desorption hysteresis, giving rise to the sequential, hystallosteric ...

Suitability of L- and U-Curve Methods for Calculating Reasonable Adsorption Energy Distributions from Nitrogen Adsorption Isotherms

open access: yesAdsorption Science & Technology, 2014
Adsorption energy distributions (AEDs) can be calculated from measured adsorption isotherms by numerical methods upon regularization of the adsorption integral equation.

Adsorption between Quercetin Derivatives and β-Glucan Studied with a Novel Approach to Modeling Adsorption Isotherms

open access: yesApplied Sciences, 2020
Interactions between polyphenols and fibers are important for polyphenol bioactivities, and have been studied in vitro with adsorption process and isotherms. However, the theoretical interpretations of adsorption potentially can be affected by the method
