“…Fe nanoparticles with an average diameter of 5 nm, synthesized by pulsed plasma in liquid method [12], were used as Fe sources. Teflon cup (total volume of 60 mL) was filled with Fe nanoparticles, 1.0 mM tetracloroauric acid (HAuCl4) as Au source, Trisodium Citrate Dehydrate (TCD: C 6H5Na3O7*2H2O) as a reducing agent for Au nanoparticles and deionized water.…”

Abstract. We present Au@Fe3O4 nanoparticles obtained from Fe nanoparticles and HAuCl4 using a simple solvothermal method. Trisodium citrate (C6H5Na3O7*2H2O) served as a reducing agent for Au. X-ray diffraction analysis, electronic microscopes and energy-dispersive X-ray spectroscopy revealed cubic structure, elemental composition (Au, Fe and O) and spherical shape of nanoparticles. Antibacterial activity of the sample was tested against E. coli bacteria and obtained results were discussed.

“…Although current methods can be used to successfully produce Sn and SnO 2 nanoparticles, they require the use of stabilizers, toxic reagents, and expensive equipment to protect the nanoparticles from agglomeration and oxidation . Our previous studies have shown that the pulsed plasma in liquid technique provides a good alternative method for the synthesis of various size‐ and shape‐controlled nanomaterials; this process is relatively cheap and environmentally friendly . The minimal heat produced by the plasma, the fact that it is produced for only a short duration (several microseconds), and the quenching effect of the surrounding cool solution limit the size of the crystals, enabling the successful synthesis of very small, metastable nanoparticles.…”

In this work, spherical Sn and SnO 2 nanoparticles smaller than 5 and 20 nm, respectively, were synthesized using pulsed plasma in deionized water, simply and environmentally friendly. The tetragonal Sn nanoparticles showed good crystallinity and slight increase in lattice parameters. Thermo-gravimetric analysis revealed insignificant weight loss from the particles, indicating their thermal stability up to 500 8C. The Sn nanoparticles then were annealed at 800 8C; in result, cassiterite phase of SnO 2 nanoparticles were successfully obtained. Structural and morphological analysis indicated the full oxidation of Sn and size growth of SnO 2 nanoparticles upto 20-25 nm. The SnO 2 nanoparticles showed good photocatalytic activity in degradation of organic dyes, such as methylene blue and methyl orange.

“…21 The production of pure Fe NPs is challenging, but aer systematic synthesis of a nanocarbon shell, the properties of Fe can present without further oxidation. 22,23 The use of the superior properties of nanocarbon structures and interfaces could be useful for many applications because of the magneto-electric effects. [24][25][26] Although the use of NPs in solution can be controlled well, MNPs are very challenging to align in a dry form because of its interactions between each particle.…”
