Synthesis of phase pure iron oxide polymorphs thin films and their enhanced magnetic properties

“…However, the spectra presented in Fig. 2c matches with the reported Raman spectra for c-Fe 2 O 3 [35], the c-Fe 2 O 3 film has three observed Raman active phonon modes at 350 cm -1 (E g ), 395 (T 2g ), 507 cm -1 (T 2g ), 670 (A 1g ) and 708 cm -1 (A 1g ), that exhibit a broad scattering response [30,34,36]. The additional peaks at 599 and 804 cm -1 , as indicated by red arrow, are contributed by the presence of a small amount of a-Fe 2 O 3 phase in the cFe 2 O 3 thin film.…”

Aqueous corrosion behaviour of Fe–Ni–B metal glasses

“…These bands characterize nickel oxides and hydroxides (NiO, Ni(OH) 2 , NiOOH); the lower wavenumber band generates from the Ni-OH stretching vibration, whilst the higher wavenumber band generates from the Ni-O stretching vibration [10,11]. Various small peaks in the range 220-720 cm −1 are assigned to iron oxides/hydroxides (␣-Fe 2 O 3 , ␥-Fe 2 O 3 , Fe 3 O 4 , ␣-FeOOH) [12].…”

Facile method to prepare magnetic multi-walled carbon nanotubes by in situ co-precipitation route

“…This technology possesses some advantages over other conventional separation techniques in terms of high capacity, short operation time and no contamination [4]. The combination between magnetic and nanostructure is therefore of a great interest for many researchers in the field of industrial and engineering chemistry because magnetic nanomaterials would provide additional function of inducing other foreign materials with opposite polarity to be attached to their surface [7][8][9]. However, preparation of such magnetic nanomaterials would require some complicated system of vacuum and/or laser ablation, resulting in very radical reports of effective preparation which would be scalable to industrial production level.…”
