“…Ablation [85][86][87] Colloidal microemulsion [48,49] Physical Vapor Deposition (PVD) [88] Sonochemical [52,[89][90][91] Wire discharge [83,92] Electrochemical [25,40,82,93] Grinding [94] Microwave [43,[95][96][97] Radiolysis [98] Hydrothermal [46,82,99] Aerosol [100] Mechanical attrition [101] obtaining nanoparticles with low quality. Several physical techniques are incorporated during or after a chemical process, for example, the laser ablation requires a colloidal solution, which minimizes the chances of oxidation on the surface of the nanoparticles, and it must be placed in a vacuum chamber in order to remove or extract atoms from a bulk surface through emission of laser beam; this method is not feasible due to the complexity of the equipment and the use of high energy for the laser [26].…”

“…As mentioned earlier, microwave-assisted hydrothermal techniques are still not well investigated because of the high capital cost of professional chemical microwave systems. There are many published papers in the literature describing the microwave-assisted hydrothermal synthesis of iron oxide particles prepared using a domestic microwave oven, without specifying microwave instrumentation and experimental conditions [12,[47][48][49][50][51][52][53] or using microwave digestion systems, where the temperature reached is calculated by the temperature/pressure ratio based on the steam tables [47,[51][52][53][54][55][56][57][58][59][60]. Few published papers described program details of a professional microwave oven, thus providing specific and well-established experimental conditions that could ensure reproducibility [50,56,[61][62][63][64].…”

“…La estructura cristalina de las partículas sintetizadas se evaluó mediante XRD previo y posterior al recubrimiento (Figura IIA4 A y B). El patrón M de los espectros de XRD presenta los picos correspondientes a las fases cristalinas de magnetita (Xavier et al, 2014). No se pudieron detectar otros picos de difracción cristalinos de óxido de hierro, lo que indica que la estructura cristalina de las nanopartículas obtenidas consistió en cristales de magnetita prácticamente puros (Fe3O4 cúbico) (Xavier et al, 2014).…”

No se observó ninguna alteración en la estructura cristalina de las nanopartículas después de recubrirlas con pectinas (magnetita cubierta) (Figura IIA4 B), lo que significa que las NP sintetizadas fueron estables luego del proceso de recubrimiento.…”
