In particular, it is necessary for materials with fine-dispersed structure characterized by high mass transfer rate, which could be due to several reasons.
One of the factors influencing on the effective diffusion properties of materials is structure.
However, with the appearance materials with micro and nano-structures, there is a need to study their diffusion properties [6].

From Medicinal Chemistry to Functionalized Biomaterials: Development of Graftable RGD-Peptitomimetics for Cell Adhesion and Cell Addressing Jacqueline Marchand-Brynaert Université catholique de Louvain, Unité de Chimie Organique et Médicinale, Bâtiment Lavoisier, Place Louis Pasteur 1, B-1348, Louvain-la-Neuve, Belgium jacqueline.marchand@uclouvain.be Keywords: Arg-Gly-Asp, RGD-peptidomimetic, αVβ3 integrin, surface grafting, PET membrane, iron oxide particle, endothelial cell cultivation, serum-free medium, T-cell targeting.
Introduction The receptors called integrins constitute an important class of biological targets in medicinal chemistry for the discovery of new drugs in the field of anti-thrombotic, anti-cancer and antiinflammatory agents, amongst others [1].
Moreover, the right positioning of the OEG-spacer (for covalent coupling on materials) was modelled by docking into the binding pocket of αVβ3 receptor from its known X-ray structure [9].
Due to the industrial process, the open surface (i.e. apparent surface and pores wall) is enriched with polymer chain-ends; it means that hydroxyl and carboxyl functions are available to realize surface wet-chemistry.

Among the materials commonly used as adsorbent, activated carbon is one of the most used materials used to remove pollutant in aqueous solutions [1] due to their high pore volume and pore size distribution conjugated with surface chemistry.
The adsorption capacity of carbon to aromatic compounds in solution depends on many factors such as the physical nature of the adsorbent(the pore structure, the ash content, the functional groups), the nature of the adsorbate (the molar mass, the size of molecules, the number and type of the functional groups, the polarity, pKa) and the chemistry of solution (pH, ionic strength, concentration of adsorbent) [2].
Acid treatment significantly changes the surface chemical properties and the pore structure of activated carbons.
The elevation of temperature does not modify the GAC surface chemistry.
Formation of other molecular complex produced by the reaction of phenol with the surface chemistry is not possible with the elevated temperatures.

Defect chemistry is considered as a very powerful approach to better the electronic conductivity of the electrode materials, thus resulting in high performance[21-23].
In this study, Li2-xFeSiO4/C (x=0.01, 0.05, 0.1) composites were prepared by a solid-state method. the effect of lithium deficiency on the lattice structure, morphology and electrochemical characterization of Li2FeSiO4 was investigated.
Results and discussion The crystal structure and phase formation of the as-obtained samples were identified using their XRD pattern, which is discribed in Fig.1.
All the peaks can be well indexed on the basis of orthorhombic structure with a Pmn21 space group.
