“…The parylene C coatings preserved magnetization for nearly 65 days for 2 µm and 82 days for 4 µm coatings (Figure 7). This may be explained by the low water and gas permeability of Parylene C [39,63] . Parylene C also exhibits a high biocompatibility, is optically transparent and flexible (∼4 GPa of Young's modulus) [64][65][66][67] , which are additional features making it suitable for marine animal monitoring applications.…”

“…PDMS offers low-cost, rapid and simple fabrication with a high degree of freedom with respect to the shapes, chemical resistance and biocompatibility of the system [36][37][38] . While progress has been made in the area of magnetic nanoparticles [39] , NdFeB micro powder is still an attractive choice, due to the high energy product, large coercive field and remanent induction [40,41] . Isotropic NdFeB powder is also inexpensive, due to the comparatively large abundance of Nd and Fe, and has good thermal aging characteristics [40][41][42] .…”

“…Synthesis of MNPs with benzyl alcohol and triethylene glycol as solvents has been shown to yield uniform MNPs in autoclaves [20][21][22][23] and by microwave-based methods [24,25]. However, all these methods required several processing steps followed by multiple washing and (often) centrifugation steps to separate the MNPs from the solvents.…”

We present a simple and rapid method for the synthesis of small magnetic nanoparticles (diameters in the order of 5-20 nm) and narrow size distributions (CV's of 20-40%). The magnetite nanoparticles were synthesized in green solvents within minutes and the saturation magnetization of the particles was tunable by changes in the reaction conditions. We show that this particle synthesis method requires minimal processing steps and we present the successful coating of the particles with reactive bisphosphonates after synthesis without washing or centrifugation. We found minimal batch-to-batch variability and show the scalability of the particle synthesis method. We present a full characterization of the particle properties and believe that this synthesis method holds great promise for facile and rapid generation of magnetic nanoparticles with defined surface coatings for magnetic targeting applications.

“…Examining the papers published in recent years, most of the studies reported the use of AEROXIDE© TIO 2 P25 (Evonik), the "gold standard" in photocatalysis [3], during photocatalytic ozonation. On the other hand, magnetic nanoparticles (MNP) gained increasing importance in different areas such as biomedicine/biotechnology [4][5][6], catalysis [7][8][9] and water treatment [10][11][12][13][14][15][16]. In spite of being widely used as catalyst supports, carbon materials as a catalyst are attracting a great deal of attention [17].…”

Magnetic nanoparticles (MNP) composed of iron oxide (or other metal–FeO cores) coated with carbon produced by chemical vapour decomposition (CVD) were used in the photocatalytic ozonation of oxamic acid (OMA) which we selected as a model pollutant. The incorporation of Ag and Cu on FeO enhanced the efficiency of the process. The carbon phase significantly increased the photocatalytic activity towards the conversion of OMA. As for the synthesis process, raising the temperature of CVD improved the performance of the produced photocatalysts. The obtained results suggested that the carbon phase is directly related to high catalytic activity. The most active photocatalyst (C@FeO_CVD850) was used in the removal of other compounds (dyes, industrial pollutants and herbicides) from water and high mineralization levels were attained. This material was also revealed to be stable during reutilisation.
