Dyes adsorption from aqueous solutions by Chitosan [PDF]

open access: yes, 2014
In this study the ability of chitosan to remove acid, basic, reactive and direct dyestuffs by adsorption was studied. The effect of several factors influencing dye adsorption such as dye concentration, grain size, pH and temperature were investigated ...

Non-Equilibrium Dynamics of Single polymer Adsorption to Solid Surfaces [PDF]

open access: yesJ. Phys.: Condens. Matter 21, 242101 (2009), 2008
Adsorption of polymers to surfaces is crucial for understanding many fundamental processes in nature. Recent experimental studies indicate that the adsorption dynamics is dominated by non-equilibrium effects. We investigate the adsorption of a single polymer of length $N$ to a planar solid surface in the absence of hydrodynamic interactions.

Synthesis of Zeolite SSZ-13 for N and CO Separation

open access: yesAdsorption Science & Technology, 2013
Zeolite SSZ-13 was synthesized by a traditional hydrothermal method, and characterized by powder X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The porous structure of the samples was determined from nitrogen uptake

Adsorption of benzene, phenol, propane and carbonic acid molecules on oxidized Al(111) and alpha-Al2O3(0001) surfaces: A first-principles study [PDF]

open access: yesJ. Phys.: Condens. Matter 21 (2009) 225001, 2009
We present the results of ab initio calculations describing the adsorption of certain small organic molecules on clean and oxidized Al(111) surfaces as well as on the alpha-Al2O3(0001) surface. Our results show that adsorption of benzene on the clean and oxidized Al(111) surfaces is generally weak, the adsorption energy being at most around -0.5 eV per

Adsorption of imidazole on Au(111) surface: Dispersion corrected density functional study [PDF]

open access: yes, 2016
We use density functional theory in the generalized gradient approximation to study the adsorption of imidazole on the Au(111) surface and account for dispersion effect using Grimme's empirical dispersion correction technique.

Synthesis and catalytic applications of combined zeolitic/mesoporous materials

open access: yesBeilstein Journal of Nanotechnology, 2011
In the last decade, research concerning nanoporous siliceous materials has been focused on mesoporous materials with intrinsic zeolitic features. These materials are thought to be superior, because they are able to combine (i) the enhanced diffusion and ...

Modelling of interacting dimer adsorption [PDF]

open access: yesSurface Sci. 612 (2013) 24-30, 2012
Adsorption of dimers is modelled using random sequential adsorption algorithm. The interaction between molecules is given by screened electrostatic potential. The paper focuses on the properties of adsorbed monolayers as well as the dependence of adsorption kinetics on interaction range.

Study of Methane Storage and Adsorption Equilibria in Multi-Walled Carbon Nanotubes [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2008
Adsorbed natural gas has various advantages and is relatively more economical than liquefaction and compression. Carbon nanotubes can be introduced as a new candidate for natural gas storage.
