Radiation induced structural and magnetic transformations in nanoparticle Mn x Zn (1−x) Fe 2 O 4 ferrites

Antibacterial and antibiofilm activities of silver-decorated zinc ferrite nanoparticles synthesized by a gamma irradiation-coupled sol–gel method against some pathogenic bacteria from medical operating room surfaces

“…The reduction in cell volume, on a large scale, can have a noticeable impact on the Ag@ZFO NPs crystallite size. [56][57][58] Further, the crystallite sizes of pure ZFO and Ag-decorated ZFO NPs samples were estimated via the Scherrer equation Table 1 The crystallite size, lattice constant, and hopping distance of ions between the A and B sites of pure ZFO NPs and Ag x @ZFO NPs (x ¼ 0.25, 0.5, and 0.75) samples…”

Gamma-irradiation induced modifications in structural and magnetic properties of nanocrystalline Mn0.5Zn0.5 SmxFe2-xO4 ceramics

“…The Rietveld refined lattice parameters are given in Table S1. The lattice parameters were found to decrease after γ-irradiation, which was also observed earlier with low doses of γirradiation in pure Mn-Zn ferrite (without Sm-doping) powders (Naik et al, 2014(Naik et al, , 2015. The shape of the XRD peaks indicates a distribution of particle sizes.…”

Composition dependent structural and morphological modifications in nanocrystalline Mn-Zn ferrites induced by high energy γ-irradiation

“…The observed phase transformations were quite prominent due to the high g-radiation dose rate (9.5 kGy/h) we have used for our study in comparison to the earlier reports [31,32]. The high dose rate is important to produce high local heat which cannot be conducted very fast unlike in the case of low dose rates.…”

“…Hence, a lot of scientific attention is given towards the girradiation induced defect creation and modification in structural and magnetic properties of ferrites. The effect of very low g-irradiation dosage (5, 100 and 200 Gy) on the properties of Mn-Zn ferrites powder was reported recently [31,32]. However, the effect of high dose (>200 Gy) gamma irradiation induced phase transformations in Mn-Zn nanoferrites are not investigated.…”
