This paper presents the synthesis and characterization of magnetite particles (covered and stabilized with mercaptoetnol) functionalized with invertase, using cyanuric chloride as spacer. The above synthesized materials were structurally characterized using Scanning Electron Microscopy, FT-IR spectroscopy, thermal analysis.
In order to combine the advantages of polysulfone (PSf) as a membrane material to that of crown ethers as complexant molecules, this paper presents the synthesis and characterization of new functionalized polysulfone membranes with crown ethers, as a potential material for sensors. The strong point of this material consists in covalent chemical bonding between crown ethers and polysulfone. This was...
A new efficient method for TiO2 fucntionalization with different molecules is presented in this paper. The method is based on TiO2 functionalization with lysine, followed by reaction between amino group from lysine and a functional group from another molecule. In this case the reaction was performed with crown ether using cyanuric chloride as spacer. An infra red spectroscopy study was performed in...
In order to combine the advantages of silica as an inorganic material (chemical resistance, optical properties) to that of polypyrrole as a conductive polymer one has attempted to obtain novel silica-polypyrrole composite particles by a newly improved technique consisting to in situ polymerization of adsorbed pyrrole into silica. The new synthesized material was characterized by FT-IR spectroscopy,...
