TL;DR: The magnetite nanoparticles were synthesized in an ethanol-water solution under ultrasonic irradiation from a Fe(OH)(2) precipitate and the monodispersibility of magnetite particles was improved significantly through the sonochemical synthesis in ethanol- water solution.

TL;DR: The dispersibility of silica-coated magnetite particles in aqueous solution was improved significantly and the agglomerate particle size was decreased to 110 nm, and it was found that theagglomerates particle size ofsilica- coated Magnetite particles was mainly decided by the coating temperature and the pH value in the silicas-coating process.

TL;DR: In this article, the properties of magnetic nanoparticles in the Brownian relaxation region were studied, and it was shown that all the magnetic properties can be well explained when taking into account the parameter distributions in the sample.

TL;DR: In this paper, the frequency dependence of the susceptibility caused by the Brownian rotation of the marker was estimated by the singular value decomposition (SVD) method, which can directly estimate the size distribution without assuming any distribution function.

TL;DR: In this paper, the formation of magnetite nanoparticles under ultrasonic irradiation in an aqueous solution was studied and the effects of dissolved gas and pH value were also studied.
