Discussion on the Gaseous Slip Model Based on Langmuir Adsorption Isotherm

Physics Procedia, 2012
AbstractDifferent from the Maxwell slip model, the gaseous slip model based on the Langmuir adsorption isotherm, i.e. the Langmuir slip model, takes into account the interfacial interaction between the gas molecules and the wall surface. For pressure-driven micro-channel gas flow, both slip models are adopted and the velocity formulae of gas flow are ...

An explicit multicomponent adsorption isotherm model: accounting for the size-effect for components with Langmuir adsorption behavior [PDF]

Adsorption, 2018
The extended Langmuir (EL) model is a popular multicomponent adsorption equilibria model, which can be based on single component Langmuir isotherms fitted on pure component data. Such explicit models are preferred over their implicit counterparts due to a lower computational requirement.

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 ...

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.
