We will discuss the role of the used surfactants and lyotropic liquid crystal phases as well as the shape and size differences depending upon when and how the resulting nanomaterials were isolated from the reaction mixture. The presented synthetic methodology using lyotropic liquid crystal solvents should be widely applicable to several other transition metal oxides for which the described reduction-hydrolysis reaction sequence is a suitable pathway to obtain nanoscale particles.<\/jats:p>","DOI":"10.3390\/nano7080211","type":"journal-article","created":{"date-parts":[[2017,8,2]],"date-time":"2017-08-02T10:05:25Z","timestamp":1501668325000},"page":"211","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Synthesis of Distinct Iron Oxide Nanomaterial Shapes Using Lyotropic Liquid Crystal Solvents"],"prefix":"10.3390","volume":"7","author":[{"given":"Seyyed","family":"Salili","sequence":"first","affiliation":[{"name":"Chemical Physics Interdisciplinary Program, Liquid Crystal Institute, Kent State University, Kent, OH 44242-0001, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthew","family":"Worden","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry, Kent State University, Kent, OH 44242-0001, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahlam","family":"Nemati","sequence":"additional","affiliation":[{"name":"Chemical Physics Interdisciplinary Program, Liquid Crystal Institute, Kent State University, Kent, OH 44242-0001, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1952-5635","authenticated-orcid":false,"given":"Donald","family":"Miller","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Therapeutics, University of Manitoba, Winnipeg, MB R3E 0T6, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6664-6598","authenticated-orcid":false,"given":"Torsten","family":"Hegmann","sequence":"additional","affiliation":[{"name":"Chemical Physics Interdisciplinary Program, Liquid Crystal Institute, Kent State University, Kent, OH 44242-0001, USA"},{"name":"Department of Chemistry and Biochemistry, Kent State University, Kent, OH 44242-0001, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,8,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2793","DOI":"10.1039\/C6NR08654C","article-title":"Controlled aggregation and cell uptake of thermoresponsive polyoxazoline-grafted superparamagnetic iron oxide nanoparticles","volume":"9","author":"Kurzhals","year":"2017","journal-title":"Nanoscale"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"3343","DOI":"10.1021\/acsami.6b12932","article-title":"Individually stabilized, superparamagnetic nanoparticles with controlled shell and size leading to exceptional stealth properties and high relaxivities","volume":"9","author":"Lassenberger","year":"2017","journal-title":"ACS Appl.
