“…Probably, changing the parameters of the applied external magnetic field and the temperature would cause the particles to become magnetised. Magnetisation is accompanied by an increase in temperature, as described, among others, in the work of Orzechowska et al [ 64 ], Winiarczyk et al [ 65 ] and Rećko et al [ 66 ].…”

In this study, we analysed the potential use of dried strawberry leaves and calyces for the production of nanoparticles using inorganic iron compounds. We used the following iron precursors FeCl3 × 6H2O, FeCl2 × 4H2O, Fe(NO3)3 × 9H2O, Fe2(SO4)3 × H2O, FeSO4 × 7H2O, FeCl3 anhydrous. It was discovered that the content of polyphenols and flavonoids in dried strawberries and their antioxidant activity in DPPH and FRAP were 346.81 µM TE/1 g and 331.71 µM TE/1 g, respectively, and were similar to these of green tea extracts. Microimages made using TEM techniques allowed for the isolation of a few nanoparticles with dimensions ranging from tens of nanometres to several micrometres. The value of the electrokinetic potential in all samples was negative and ranged from −21,300 mV to −11,183 mV. XRF analyses confirmed the presence of iron ranging from 0.13% to 0.92% in the samples with a concentration of 0.01 mol/dm3. FT-IR spectra analyses showed bands characteristic of nanoparticles. In calorimetric measurements, no increase in temperature was observed in any of the tests during exposure to the electromagnetic field. In summary, using the extract from dried strawberry leaves and calyxes as a reagent, we can obtain iron nanoparticles with sizes dependent on the concentration of the precursor.

Gallium ferrite nanoparticles (GFOnps) were synthesized using modified sol-gel technique and its physical, chemical, and optical properties were studied. GFOnps was synthesised at room temperature and calcined at 900°C to obtain pure orthorhombic (Pc21n) phase of GFOnps. They were evaluated for the photocatalytic degradation of azine dyes: methyl violet (MV) and methylene blue (MB). The structural studies performed using XRD and Raman spectroscopy, XRD and Raman spectra showed pure phase with orthorhombic structure (Pc21n) without any impurities. The UV-Vis measurement showed a broad absorption band around 500nm-800nm range. The energy band gap calculation using the Tauc plot was performed and Eg was found to be 2.08eV. EDS measurement displayed the complete elemental composition. Transmission electron microscopy was used to study the morphological and structural properties of GFOnps. The observation showed evenly distributed particles at the surface with particle size ranging from 20-40nm. Multiferroic property analysis of GFOnps were performed using VSM and PE measurements respectively at room temperature. In PE study, irregular hysteresis loop was observed, while in magnetic measurement ferrimagnetic hysteresis loop was obtained which was not found to be saturating at the applied magnetic field of 6T. In the photocatalytic degradation study, dye degradation percentage was 97% for Methyl Violet and 56.6% for Methylene Blue in 120 min and 150 min, respectively. Cyclic study showed re-usability of the GFOnps for up to 3 cycles. Thus, GFOnps have showcased excellent photocatalytic performance over two azine dyes and also showed room temperature multiferroic performance.
