Binding adsorption
WebThe Langmuir adsorption isotherm provides one of the simplest and most direct methods to quantify an adsorption process. Because isotherm data from protein adsorption studies … Adsorption is the adhesion of atoms, ions or molecules from a gas, liquid or dissolved solid to a surface. This process creates a film of the adsorbate (solute )* on the surface of the adsorbent(solvent). This process differs from absorption, in which a fluid (the absorbate) is dissolved by or permeates a liquid or solid … See more The adsorption of gases and solutes is usually described through isotherms, that is, the amount of adsorbate on the adsorbent as a function of its pressure (if gas) or concentration (for liquid phase solutes) at constant … See more Characteristics and general requirements Adsorbents are used usually in the form of spherical pellets, rods, moldings, or monoliths with a hydrodynamic radius between 0.25 and 5 mm. They must have high abrasion resistance, high thermal stability and … See more The low cost ($200/ton) and high cycle rate (2,000 ×) of synthetic zeolites such as Linde 13X with water adsorbate has garnered much academic and commercial interest recently for use for thermal energy storage (TES), specifically of low-grade solar and waste … See more Protein adsorption is a process that has a fundamental role in the field of biomaterials. Indeed, biomaterial surfaces in contact with biological … See more Since 1980 two theories were worked on to explain adsorption and obtain equations that work. These two are referred to as the chi hypothesis, the quantum mechanical derivation, and excess surface work (ESW). Both these theories yield the same equation for flat … See more The adsorption of water at surfaces is of broad importance in chemical engineering, materials science and catalysis. Also termed surface … See more Typical adsorbents proposed for carbon capture and storage are zeolites and MOFs. The customization of adsorbents makes them a potentially … See more

WebDec 21, 2016 · Thermodynamically speaking, adsorption occurs when the free energy between a protein and a surface is less than that of the surface and water (the bulk solvent). Because plastics and other commonly used materials in the lab tend to have relatively high free energies compared to bulk water, these interfaces are often stabilized by … WebAmmonia (NH3) is a promising energy resource owing to its high hydrogen density. However, its widespread application is restricted by the lack of efficient and corrosion-resistant storage materials. Here, we report high NH3 adsorption in a series of robust metal–organic framework (MOF) materials, MFM-300(M) (M = Fe, V, Cr, In). MFM …
WebSteric mass action (SMA) model – ion exchange chromatography. The SMA isotherm is a common model for ion exchange chromatography (IEC) using multi-point binding, the influence of counter-ions, and displacement. This isotherm model is based on a stoichiometric exchange of ions on an oppositely charged surface. The adsorbing protein … WebMolecules bind to the PolySorp and MaxiSorp surfaces through passive adsorption. Using IgG as a reference molecule and knowing that it is a globular molecule, theoretical …
