Generalized Fick Jacobs Approach for describing Adsorption Desorption Kinetics in Irregular Pores under Non Equilibrium Conditions

open access: yes, 2016
We present a study exploring the range of applicability of a generalized Fick Jacobs equation in the case when diffusive mass transport of a fluid along a pore includes chemical reactions in the bulk and pore surface.

Adsorption of Streptococcus mutans on Chemically Treated Hydroxyapatite [PDF]

open access: yesJournal of Dental Research, 1978
Adsorption of Streptococcus mutans on hydroxyapatite and chemically treated hydroxyapatite was studied. Zeta potentials of the surfaces were measured. Chemically treated hydroxyapatite gave higher ζ potentials and lower S mutans adsorption.

Strain engineering of selective chemical adsorption on monolayer MoS2. [PDF]

open access: yesNanoscale, 2013
Nanomaterials are prone to influence by chemical adsorption because of their large surface to volume ratios. This enables sensitive detection of adsorbed chemical species which, in turn, can tune the properties of the host material.

Recent advances in removal of Congo Red dye by adsorption using an industrial waste

open access: yesScientific Reports, 2022
The Congo Red dye was removed from a simulated textile wastewater solution using fly ash from a local power plant. The characterisation of fly ash was studied in detail by SEM, EDX, XRD, FTIR, BET surface area and TGA techniques.

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

The nature of small molecules adsorbed on defective carbon nanotubes [PDF]

open access: yesRoyal Society Open Science, 2019
In this work, we perform a comprehensive theoretical study on adsorption of representative 10-electron molecules H2O, CH4 and NH3 onto defective single-walled carbon nanotubes. Results of adsorption energy and charge transfer reveal the existence of both

Theory, Simulation and Nanotechnological Applications of Adsorption on a Surface with Defects [PDF]

open access: yes, 1998
Theory of adsorption on a surface with nanolocal defects is proposed. Two efficacy parameters of surface modification for nanotechnological purposes are introduced, where the modification is a creation of nanolocal artificial defects. The first parameter

Adsorption of CO2 on Activated Carbons Prepared by Chemical Activation with Cupric Nitrate

open access: yesACS Omega, 2020
Activated carbons were prepared from a lignocellulosic material, African palm shells (Elaeis guineensis), by chemical impregnation of the precursor with solutions of 1–7% w/v Cu(NO3)2 at five different concentrations.

Zeolites in Adsorption Processes: State of the Art and Future Prospects

open access: yesChemical Reviews, 2022
Zeolites have been widely used as catalysts, ion exchangers, and adsorbents since their industrial breakthrough in the 1950s and continue to be state-of the-art adsorbents in many separation processes. Furthermore, their properties make them materials of
