Ramos Guivar Juan A. is also grateful to FONDECYT (Grant No. 0218-2014).The preparation and functionalization of iron oxide magnetic nanoparticles (MNPs) are of great importance in a diverse range of applications. However, their structural and magnetic properties can be influenced by the process of coating making these MNPs undesirable for certain applications. For that reason, this work is focused in the understanding of iron oxide nanoparticles functionalized with fatty functional lauric acid (LA) and oleic acid (OA) organic molecules. The synthesis was carried out using the aqueous alkaline co-precipitation route of Fe+2 and Fe3+ salts. The characterization was done by several spectroscopy techniques. X-Ray Diffraction (XRD) measurements reveal uncoated iron oxide nanoparticles with mean diameter of 11.8 ± 2 nm obtained from Debye-Sherrer formula. The spinel crystal structure and lattice parameter was found to be 8.38 ± 0.01 Å which means that the stoichiometric structure is not affected by the functionalization process. This size decreased at around 9.7 ± 2 and 8.6 ± 2 nm for coated with OA and LA which are in agreement with Transmission Electron Microscopy (TEM) measurements. X-ray Photoelectron Spectroscopy (XPS) measurements determined that iron atoms have valences of +3 and +2, with a total ratio of iron atoms Fe+3: Fe+2 of 2:1 which confirmed the stoichiometric relation used for magnetite (Fe3O4). Fourier Transform Infrared Spectroscopy (FTIR) measurements show that LA and OA molecules are chemisorbed onto MNPs surface ascribed to bridging bidentate interaction. The thermal stability of the functional groups anchored to magnetite surface was studied by thermogravimetric analysis (TGA) at certain range of temperatures. From TGA measurements we calculate the number of functionalized molecules anchored to the surface of Fe3O4 nanoparticles. Micro-Raman spectroscopy was introduced to study the stabilization of organic molecules on MNPs surface.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengTANGER Ltd.NANOCON 2015 - 7th International Conference on Nanomaterials - Research and Application, Conference Proceedingsinfo:eu-repo/semantics/openAccessX ray photoelectron spectroscopyCoprecipitation-1Crystal structure-1Fatty acids-1Fourier transform infrared spectroscopy-1Fourier transform infrared spectroscopy-1High resolution transmission electron microscopy-1Iron-1Magnetite-1Magnetite nanoparticles-1Metal nanoparticles-1Molecules-1Nanomagnetics-1Nanoparticles-1Nanostructured materials-1Precipitation (chemical)-1Semiconducting bismuth compounds-1Thermodynamic stability-1Thermogravimetric analysis-1Transmission electron microscopy-1X ray diffraction-1Functionalization process-1Functionalizations-1Iron oxide nanoparticle-1Magnetic nanoparti cles (MNPs)-1Micro Raman Spectroscopy-1Stabilization of organic molecule-1Stabilization of organic molecule-1Stoichiometric structure-1Structural and magnetic properties-1Structural and magnetic properties-1Iron oxides-1https://purl.org/pe-repo/ocde/ford#1.03.00-1Structural and vibrational studies of fatty acids-functionalized iron oxide nanoparticles via alkaline co-precipitation routeinfo:eu-repo/semantics/conferenceObjectreponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#20.500.12390/780oai:repositorio.concytec.gob.pe:20.500.12390/7802024-05-30 15:22:54.51http://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="b02b087d-d073-483a-afe6-a10b840e02ee"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>Structural and vibrational studies of fatty acids-functionalized iron oxide nanoparticles via alkaline co-precipitation route</Title> <PublishedIn> <Publication> <Title>NANOCON 2015 - 7th International Conference on Nanomaterials - Research and Application, Conference Proceedings</Title> </Publication> </PublishedIn> <PublicationDate>2015</PublicationDate> <SCP-Number>2-s2.0-84962815178</SCP-Number> <ISBN>9788087294635</ISBN> <Authors> <Author> <DisplayName>Herrera W.T.</DisplayName> <Person id="rp02004" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Ramos Guivar J.A.</DisplayName> <Person id="rp00676" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>González J.C.</DisplayName> <Person id="rp00681" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Baggio-Saitovitch E.M.</DisplayName> <Person id="rp02003" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>TANGER Ltd.</DisplayName> <OrgUnit /> </Publisher> </Publishers> <Keyword>X ray photoelectron spectroscopy</Keyword> <Keyword>Coprecipitation</Keyword> <Keyword>Crystal structure</Keyword> <Keyword>Fatty acids</Keyword> <Keyword>Fourier transform infrared spectroscopy</Keyword> <Keyword>Fourier transform infrared spectroscopy</Keyword> <Keyword>High resolution transmission electron microscopy</Keyword> <Keyword>Iron</Keyword> <Keyword>Magnetite</Keyword> <Keyword>Magnetite nanoparticles</Keyword> <Keyword>Metal nanoparticles</Keyword> <Keyword>Molecules</Keyword> <Keyword>Nanomagnetics</Keyword> <Keyword>Nanoparticles</Keyword> <Keyword>Nanostructured materials</Keyword> <Keyword>Precipitation (chemical)</Keyword> <Keyword>Semiconducting bismuth compounds</Keyword> <Keyword>Thermodynamic stability</Keyword> <Keyword>Thermogravimetric analysis</Keyword> <Keyword>Transmission electron microscopy</Keyword> <Keyword>X ray diffraction</Keyword> <Keyword>Functionalization process</Keyword> <Keyword>Functionalizations</Keyword> <Keyword>Iron oxide nanoparticle</Keyword> <Keyword>Magnetic nanoparti cles (MNPs)</Keyword> <Keyword>Micro Raman Spectroscopy</Keyword> <Keyword>Stabilization of organic molecule</Keyword> <Keyword>Stabilization of organic molecule</Keyword> <Keyword>Stoichiometric structure</Keyword> <Keyword>Structural and magnetic properties</Keyword> <Keyword>Structural and magnetic properties</Keyword> <Keyword>Iron oxides</Keyword> <Abstract>The preparation and functionalization of iron oxide magnetic nanoparticles (MNPs) are of great importance in a diverse range of applications.
