The synthesis and the physico-chemical characterisation of a novel solid phase, designed for iron(iii) sorption, are presented. The solid (indicated in the following as DFO-SAMMS) is made with a hydroxamate siderophore, the deferoxamine (DFO), covalently bound on a self-assembled monolayer on mesoporous silica (SAMMS). The data demonstrate that the DFO molecules are bound to the solid material,...

Luminescent inorganic nanoparticles are now widely studied for their applications as biological probes for in vitro or in vivo experiments. The functionalization of the particles is a key step toward these applications, since it determines the control of the coupling between the particles and the biological species of interest. This paper is devoted to the case of rare earth doped oxide nanopar...

Inorganic/organic sol–gel hybrids have nanoscale co-networks of organic and inorganic components that give them the unique potential of tailored mechanical properties and controlled biodegradation in tissue engineering applications. Here, silica/chitosan hybrid scaffolds with oriented structures were fabricated through the sol–gel method with a unidirectional freeze casting process. 3-Glycidoxy...

High-performance coating could be used to protect steels in engineering. The GPTMS-TEOS hybrid coatings were successfully prepared using (3-glycidoxypropyl) trimethoxysilane (GPTMS) and tetraethylorthosilicate (TEOS) as reaction raw materials diethylenetriamine (DETA) both a curing agent catalyst at room temperature. contained amorphous SiO2 was characterized by means of X-ray diffraction (XRD)...

Abstract Mg alloys are considered a promising alternative to use as biodegradable implants. However, the main limitations of these high susceptibility hydrogen evolution and corrosion. Consequently, it is necessary control corrosion rate through surface treatment techniques. In this regard, double layer system, based on first deposition MgO coating subsequent an organo-silane sol-gel (anodized/...

The entrapment of proteins using the sol-gel route provides a means to retain its native properties and artifi cially reproduce the molecular crowding and confi nement experienced by proteins in the cell allowing investigation of the physico-chemical and structural properties of biomolecules at the biotic/abiotic interface. The biomolecules are spatially separated and ‘caged’ in the gel structu...

In this communication, a bis-silane prepolymer was used to modify epoxy resin, aiming enhance the corrosion resistance of coatings on aluminum alloy substrates. The prepared by tetraethoxysilane (TEOS) and γ-glycidoxypropyl trimethoxysilane (GPTMS). behavior silane-epoxy studied. Compared with silane monomer-modified coatings, bis-silane-modified have lower coating capacitance (Cc), higher char...
