“…High-energy ball mill has been widely used to produce ultra ne particles even in a nano range [67]. This mechanical milling or mechanochemistry method is capable of fabricating solid-solid, solid-liquid, and solid-gases reactions that do not usually happen at ambient temperature and is feasible for large-scale implementation [68]. Since the mass ratio of powder to ball mill was 1:10, in this work, 50 g of powders was milled or ground by 500 g of hardened steel ball in 50 ml of ethanol for an hour.…”

Abstract. This study reports a reclamation method of Ground Tire Rubber (GTR) and electronic wastes into a tunable sti ness composite, namely magnetorheological elastomers (MREs). The composite matrix was the GTR that had been separated from its metals and yarns. Meanwhile, the llers were fabricated from magnetic cores of the Cathode Ray Tubes (CRTs) monitor waste through high energy ball milling in wet condition. Some physicochemical characterizations of the powders were initially conducted to collect the physical and chemical properties. Based on the examination, the ground powders were identi ed as pure magnetite (Fe 3 O 4 ) having low remnant and high magnetization. The MREs samples were prepared by high-temperature high-pressure sintering. The mixed of crumb rubber and magnetite powder was vulcanized under simultaneous pressure and temperature in the absence of magnetic elds, which resulted in an isotropic MREs type. The abilities of specimens were examined in relation to the external magnetic eld through static and dynamic compression tests. The experimental investigation showed that the static and dynamic stresses of the sti ness increased by the increment of magnetic elds up to a particular point of ux density. The tunability of the sti ness indicated that the elastomers could provide wide ranges of storage and loss modulus.

“…The spectra show two sharp absorption peaks at approximately 520 and 430 cm -l . The two bands in the ranges of 700 to 500 cm -l and 500 to 300 cm -l are characteristic of magnetite and can be used to distinguish this phase quite easily from maghemite (γ- The weak band at approximately 630 cm -1 matched the characteristic peak of Fe 3 O 4 [42].…”

“…These magnetite IONPs have been prepared using a variety of techniques including sol-gel formation [19,20], hy-drothermic approaches [21,22], solid state synthesis [23][24][25], wet milling [26,27], pyrolysis [28,29], microemulsion [30][31][32], and electrochemistry [33,34]. However, although the ease and control of the electrochemical method has made it a particularly promising approach, surfactants are often used to assist in the synthesis and prevent aggregation.…”

Magnetite (Fe3O4) nanoparticles, are promising inorganic nanomaterials for future biomedical applications due to their low toxicity and unique magnetic properties. However, the synthesis of these particles can often be expensive, energy intensive, and non-scalable, requiring the addition of surfactants to stabilize the material to control the particle size and avoid agglomeration. We wish to report a simple, green, surfactant-free electrochemical synthesis of these materials using a closed aqueous system at ambient temperature. Particle diameter, between 19 and 33 nm, was controlled by simply modifying the distance between the electrodes. These magnetite nanoparticles were then fully characterized using both spectroscopy and microscopy. Vibrational magnetometry indicates that as the size of the particle decreases, the magnetic hysteretic gap decreases, although for samples below 25 nm no inter-sample difference was observed. To support this experimental data, we carried out a Density Functional Theory (DFT) analysis of magnetite containing more than three iron atoms in the cluster, an essential proposition as magnetite contains three distinct iron species. These calculations were used to support the experimental observations, and closely reproduced both the experimental IR spectrum, and the XRD pattern. In vitro cytotoxicity assays showed dose responsive behavior for the nanoparticles, and demonstrated that they are non-toxic at clinically relevant concentrations; below 200 µg/mL we observed no toxicity in a 48-hour standard assay. This work represents the first DFT based simulation of this detailed magnetite cluster, and demonstrates that this sustainable synthetic method is capable of producing nanomaterials with a physical and biological profile that might make them suitable for biomedical applications.
