Sputtering on liquids – a versatile process for the production of magnetic suspensions?

Rheology and colloidal structure of silver nanoparticles dispersed in diethylene glycol

“…A colloid of silver nanoparticles in DEG (MERCK, 8.03131.5000) at volumetric solids concentration (ϕ) of 4.37% was produced by the "Sputtering on Running Liquid" technique (VERL) [3,4]. No stabilizing agent has been used throughout the preparation process.…”

“…Regarding the flow behavior, Namburu et al [1] have shown that at relatively low CuO nanoparticle concentration (b6.12 vol.%) dispersed in ethylene glycol and water mixture, nanofluids exhibit Newtonian flow behavior. In contrast, a nanoparticle cobalt-based magnetorheological fluid shows a nonlinear shear stress-shear rate behavior [4]. Rheological study of TiO 2 nanoparticle suspensions by Tseng and Lin [5] has indicated pseudoplastic behavior in the volumetric solids concentration of 5-12%.…”

Preparation of polysulfone–Fe3O4 composite ultrafiltration membrane and its behavior in magnetic field

“…The composite membrane has magnetism and is performed in a magnetic field. Fe 3 O 4 nanoparticles have been used in the magnetic liquid, magnetic memorizing material, magnetic polymer microspheres and so on for its superparamagnetism [14][15][16][17][18][19]. They will be magnetized and arrange along the magnetic line of force in magnetic field, and when the field is moved away, they can come back quickly.…”

On the formation of anisotropic gold nanoparticles by sputtering onto a nitrile functionalised ionic liquid

“…[1][2][3][4][5] Due to the high purity of these NPs, they are suitable for a variety of applications such as magnetic fluids, 1 nonlinear optics, biomedicine and catalysis. 6 Among all employed PVD methods to prepare colloidal NPs, sputtering deposition onto ionic liquids (ILs) has several advantages since its versatility allows a good control over the size and size distribution of the NPs, 7,8 which is of great importance for special applications.…”
