Efficient photo-Fenton catalysis using magnetic iron nanoparticles decorated boron nitride quantum dots: theoretical and experimental investigations

“…Fig. 2B displays the XRD pattern of Fe@BNQDs, the peaks are located at 2 θ (theta) equal to 14.62° (boron nitride, BN, and Fe 3 B), 57 24.15° (Fe 2 B), 58 26.4° (BN), 27.93° (BN Fe 2 B), 58 33.1° (Fe 3 B), 57 35.62° (Fe 2 B), 58 40.83° (BN and FeN 0.06 ), 59 43.35° (BN, Fe 2 N), 60 44.4° (BN) 49.48° (Fe 2 B), 58 54.1° (Fe 3 B), 57 54.93° (BN), 55.48° (BN), 57.62° (Fe 3 B), 57 62.45° (Fe 2 N), 60 64° (Fe 2 N), 60 71.93° (BN, Fe 2 N), 60 these data match with those obtained from the JCPDS cards (no. 96-101-1241, 61 no.…”

“…56 Fig. 2B displays the XRD pattern of Fe@BNQDs, the peaks are located at 2q (theta) equal to 14.62°(boron nitride, BN, and Fe 3 B), 57 24.15°(Fe 2 B), 58 26.4°(BN), 27.93°(BN Fe 2 B), 58 33.1°( Fe 3 B), 57 35.62°(Fe 2 B), 58 40.83°(BN and FeN 0.06 ), 59 43.35°(BN, Fe 2 N), 60 44.4°(BN) 49.48°(Fe 2 B), 58 54.1°(Fe 3 B), 57 54.93°(BN), 55.48°(BN), 57.62°(Fe 3 B), 57 62.45°(Fe 2 N), 60 64°(Fe 2 N), 60 An XRD pattern was used to measure the crystallinity index (CI), 28,67,68 which was found to be 68.8 for BNQDs before decoration with Fe and 76.6 for Fe@BNQDs. It is worth mentioning that CI was measured from the ratio of the integrated area of all crystalline peaks to the total integrated area under the XRD peaks.…”

In situ Investigation of Magnetism in Metastable Phases of Levitated Fe83B17 During Solidification

“…A series of investigations by Barinov et. al [34] the Rietveld refinements and raw x-ray data if any of the f cc Fe remains at room temperature, and as past work has demonstrated [10], the overlap of peaks resulting from coherency together with extremely strong texturing make quantitative measurements of the f cc Fe and Fe 23 B 6 fractions challenging. However, the nature of the coherent stabilization might imply a kinetic barrier to further transformation at low temperature, leaving some small grains of f cc Fe throughout the sample.…”

Investigation of the Critical Behavior, Magnetocaloric Effect and Hyperfine Structure in the Fe72Nb8B20 Powders

“…Indeed, existence of one B atom as the nearest neighbor (nn) of an Fe atom raises IS by about 0.07 mm/s. In such Fe(B) sites, the average number of B atoms (n B ) can be estimated from the linear relationship between the hyperfine magnetic field (B hf ) and the number of B atoms [28]: B hf = 33.6-2.7n B . Accordingly, the number of B atoms in the sextet SS1 is about n B = 0.22.…”
