Journal ArticleDOI
Size-driven structural and thermodynamic complexity in iron oxides.
TL;DR: In this paper, the authors summarized recently measured thermodynamic data on the formation and surface energies of various iron oxides and showed that polymorphs metastable as micrometer-sized or larger crystals can often be thermodynamically stabilized at the nanoscale.
Journal ArticleDOI
Calorimetric Study of Maghemite Nanoparticles Synthesized by Laser-Induced Pyrolysis
TL;DR: The thermodynamic properties of Maghemite (γ-Fe2O3) nanoparticles with size smaller than 10 nm were studied in this paper, where they were synthesized by wet chisels.
Journal ArticleDOI
Cathodoluminescence Studies of the Inhomogeneities in Sn-doped Ga2O3 Nanowires
S. I. Maximenko,Lena Mazeina,Yoosuf N. Picard,Jaime A. Freitas,Victor M. Bermudez,Sharka M. Prokes +5 more
TL;DR: Cathodoluminescence real-color imaging and spectroscopy were employed to study the properties of Ga(2)O(3) nanowires grown with different Sn/Ga ratios, showing large spectral emission variation, ranging from blue to red, with a green transition zone.
Journal ArticleDOI
Energetics of Bulk and Nano-Akaganeite, β-FeOOH: Enthalpy of Formation, Surface Enthalpy, and Enthalpy of Water Adsorption
TL;DR: In this paper, the enthalpy of Akaganeite was studied by solution calorimetry in aqueous HCl, and the enthpy of water adsorption was studied using a new Calvet microcalorimeter and an automated gas dosing system.
Journal ArticleDOI
Enthalpy of Water Adsorption and Surface Enthalpy of Goethite (α-FeOOH) and Hematite (α-Fe2O3)
Lena Mazeina,Alexandra Navrotsky +1 more
TL;DR: In this paper, the enthalpies of adsorbed water relative to liquid water (ΔHads) equal to −67.1 ± 4.9, −48.6 ± 1.8, and −25.5± 4.4 kJ/mol were determined for anhydrous surfaces of goethite and hematite.
