Novel ferrofluids coated with a renewable material obtained from cashew nut shell liquid

“…Numerous synthetic approaches have been developed to produce magnetic nanoparticles, such as sonochemical (Kim et al 2005), sol-gel pyrolysis method (Laokul et al 2011), hydrothermal technique (Cote et al 2003), thermal reductive decomposition (Xu et al 2009) and mechanical alloying (Waje et al 2010). However, as it is well known, co-precipitation is one of the most diffused and low-cost technique for the production of magnetic nanoparticles, due to its simplicity and efficient chemical pathway to the preparation of various interesting solid-state materials (Shi et al 1999;Waje et al 2010).…”

“…In recent years, Fe 3 O 4 , CoFe 2 O 4 and NiFe 2 O 4 nanocrystals have been intensively investigated due to their interesting magnetic properties and as plausible applicative candidates in the information storage systems, magnetic nanodevices, drug delivery, magnetic hyperthermia, medical diagnostics and ferrofluids (Shi et al 1999;Chitu et al 2007). Numerous synthetic approaches have been developed to produce magnetic nanoparticles, such as sonochemical (Kim et al 2005), sol-gel pyrolysis method (Laokul et al 2011), hydrothermal technique (Cote et al 2003), thermal reductive decomposition (Xu et al 2009) and mechanical alloying (Waje et al 2010).…”

Effect Investigation of Zn Substitution on the characterization of Cobalt Ferrite Nano Particles Prepared Co-precipitation method

“…Addition of zinc also affects the lattice parameter (a 0 ).Various preparation techniques, such as reverse micelletechnique [8][9], sol-gel pyrolysis method [10] hydrothermal technique [11] and mechanical alloying [12] areused to prepare ferrite nanoparticles. But coprecipitationmethod is considered to be economical means of producingfine particles [13,14].The electrical and dielectrical properties were also studied forCo-Zn ferrite, it was reported that the composition Co 0.6 Zn 0.4 Fe 2 O 4 has a high value of electrical conductivity, dielectric constant andmagnetic permeability [15,16].…”
