Competitive adsorption of p-hydroxybenzoic acid and phenol on activated carbon : experimental study and modelling. [PDF]

, 2013
The competitive adsorption of phenol and p-hydroxybenzoic acid (4HBA) has been investigated on activated carbon (AC) for a wide range of concentrations under unbuffered conditions. The results show a preferential adsorption of 4HBA which can be explained

Impact of methane adsorption on tight rock permeability measurements using pulse-decay

Petroleum, 2019
The permeability of the rock is usually measured by the injection of gas using Darcy's flow model (pulse-decay). For oil formations, helium and nitrogen are the most common gases used to measure the permeability of the rock.

Study of Adsorption-Desorption on Batik Industrial Dyes (Naphthol Blue Black) on Magnetite Modified Humic Acid (HA-Fe3O4)

Jurnal Kimia Sains dan Aplikasi, 2020
The rapid development of the batik industry can pollute water resources and become an increasingly severe problem. This research studies the adsorption-desorption of naphthol blue-black (one of the dyes in batik liquid waste) by magnetite modified humic ...

Adsorption of Methyl Orange and Amoxicillin from Water using Metal-organic Framework Prepared from Solvothermal Mixing of Zn ions and 1,4-Benzenedicarboxylic Acid Moieties

Journal of Applied Sciences and Environmental Management, 2023
In this study, we determined the capacity of metal organic framework, which we prepared by the solvothermal mixing of Zn ions and 1,4-benzenedicarboxylic acid (Zn/BDC) moieties to adsorb methyl orange (MO), and amoxicillin (AMX).

Two‐Dimensional Materials as a Multiproperty Sensing Platform

Advanced Functional Materials, EarlyView.
Various sensing modalities enabled and/or enhanced by two‐dimensional (2D) materials are reviewed. The domains considered for sensing include: 1) optoelectronics, 2) quantum defects, 3) scanning probe microscopy, 4) nanomechanics, and 5) bio‐ and chemosensing.

Molecular Cross‐Linking of MXenes: Tunable Interfaces and Chemiresistive Sensing

Advanced Functional Materials, EarlyView.
In this study, Ti3C2Tx MXenes are initially functionalized using oleylamine ligands to form stable dispersions in an organic solvent. Subsequently ligand exchange with α,ω‐diaminoalkanes enables cross‐linking, along with precise tuning of interfaces. This structural control translates into tunable charge transport and responsive VOC sensing, showing ...

Breakdown of Langmuir Adsorption Isotherm in Small Closed Systems

Langmuir, 2023
For more than a century, monolayer adsorptions in which adsorbate molecules and adsorbing sites behave ideally have been successfully described by Langmuir adsorption isotherm. For example, the amount of adsorbed material, as a function of concentration of the material which is not adsorbed, obeys Langmuir's equation.

Enantioselective Growth of Chiral Serine‐Induced β‐Ag2Se Crystals from an Organoselenium Compound

Advanced Functional Materials, EarlyView.
Chiral amino acids direct the enantioselective crystallization of β‐Ag2Se nanocrystals from an organoselenium precursor. L‐ and D‐serine induce distinct morphologies and opposite homochiral adsorption preferences, transferring molecular handedness into the inorganic lattice.
