“…These OH groups absorb IR waves at about 1630 cm −1 (deforming) and 3400 cm −1 (stretching). [2][3][4]6,[35][36][37] In amino-acid coated nanoparticles the C=O and C-O stretching vibrations can be seen at ~1630 cm −1 and 1439 cm −1 respectively. The peak at 2921 cm −1 is due to C-H stretching vibration and N-H stretching vibration overlaps with OH stretching at 3419 cm…”

Iron-oxide nanoparticles (IONs) with biocompatible coatings are the only nanostructural materials which have been approved by the FDA for clinical use. Common biocompatible coatings such as hydrocarbons, polymers, and silica have profound influences on critical characteristics of IONs. Recently, amino acids were introduced as a novel biocompatible coating. In the present study, the effects of amino acids on IONs synthesis and characteristics have been evaluated. Magnetite nanoparticles with L-arginine and L-lysine coatings were synthesised by a coprecipitation reaction in aqueous solvent and their characteristics were compared with naked magnetite nanoparticles. The results showed that amino acids can be a perfect coating for IONs and would increase particle stability without any significant effects on the critical properties of nanoparticles such as particle size and magnetization saturation value.

It could be seen that characteristic absorption bands of the Fe-O stretching vibration ascribed at 559.2 cm -1 [14,15], and the contribution of the absorption at 3400 cm -1 was attributed to O-H band [16]. The absorption bands at 1623.1 cm -1 [17,18] and 1396.2 cm -1 [8] revealed that the presence of an amino group (N-H) as shown in Fig.…”

Abstract. Lipase-catalyzed biodiesel production is being the object of extensive research due to the demerits of chemical based catalytic system. Lipase immobilized on Fe3O4 magnetic nanoparticles has the integrated advantages of traditional immobilized lipase and free lipase for its rather fast reaction rate and easy separation. It has been demonstrated that free lipase NS81006 has potential in catalyzing the alcoholysis of renewable oils for biodiesel preparation. In this study, Fe3O4 magnetic nanoparticles functionalized with organosilane compounds like (3-aminopropyl)triethyloxysilane (APTES) and (3-mercaptopropyl)trimethoxysilane) MPTMS were used as carriers for lipase immobilization. Lipase NS81006 was covalently bound to the organosilane-functionalized magnetic nanoparticles by using glutaraldehyde cross-linking reagent. A biodiesel yield of 89% and 81% could be achieved by lipase immobilized on APTES-Fe3O4 and MPTMS-Fe3O4 magnetic nanoparticles respectively under optimized conditions of oil to methanol molar ratio 1:3 with three step addition of methanol, reaction temperature 45°C and reaction time duration 12 h. The lipases immobilized on magnetic nanoparticles could be recovered easily by external magnetic field for further use.

Magnetic vinylphenyl boronic acid microparticles, poly(ethylene glycol dimethacrylate-vinylphenyl boronic acid) [mpoly(EGDMA-VPBA)], produced by suspension polymerization, was found to be efficient solid acid catalyst for the esterification of methanol and propionic acid. Characterization techniques such as FT-IR, Elemental analyses, ICP-AES, ESR, SEM and N2 sorption showed that both of Fe3O4 and H2SO4 are bonded to the polymer successfully. Esterification was studied for different molar percentages of H2SO4 at temperature range of 50-70 o C. The apparent activation energy was found to be 28.4 kj.mol -1 for 10% H2SO4 doped m-poly(EGDMA-VPBA). Combining of strong acid H2SO4 with m-poly(EGDMA-VPBA), leads to materials with different functional properties. In addition, H2SO4 species could be introduced into the structure as acid centers, therefore this micro-dimensional catalyst has potential candidate for applications in the catalytic esterifications such as propionic acid with methanol.
