Adsorption of Metallocenes on Silica

Investigation of Carbon Dioxide Adsorption on Amino-Functionalized Mesoporous Silica

Carbon dioxide (CO2) adsorption on unfunctionalized and amino-functionalized SBA-3 materials are investigated and compared in this study. The synthesized materials are characterized by various techniques such as X-ray diffraction (XRD), Brunauer-Emmet-Teller (BET) method, Fourier transform infrared (FT-IR) and Scanning electron microscopy (SEM).The isotherms of these materials have been measure...

Selective adsorption of metallocenes on clean and chemically modified Si(111) surfaces

Adsorption of n-pentane on mesoporous silica and adsorbent deformation.

Development of quantitative theory of adsorption-induced deformation is important, e.g., for enhanced coalbed methane recovery by CO2 injection. It is also promising for the interpretation of experimental measurements of elastic properties of porous solids. We study deformation of mesoporous silica by n-pentane adsorption. The shape of experimental strain isotherms for this system differs from ...

Thermodynamics Study of Solvent Adsorption on Octadecyl-Modified Silica

Elution and solvation processes in liquid chromatography may be controlled by temperature changes. In the case of solvent adsorption, the temperature influences the amount of adsorbed solvent as well as the enthalpy and entropy of the solvation process. In this work, the thermodynamic parameters of organic solvents used as organic modifiers in the reversed-phase high-performance liquid chromato...

Adsorption of viruses to charge-modified silica.

The purpose of this study was to provide a clearer understanding of virus adsorption, focusing specifically on the role of electrostatic interactions between virus particles and adsorbent surfaces. The adsorption of poliovirus 1, reovirus types 1 and 3, and coliphages MS-2 and T2 to colloidal silica synthetically modified to carry either positive or negative surface charge was evaluated. Adsorp...
