“…The SAR obtained from MNPs was concluded to be field-amplitude dependent and a critical variable for thermal therapy. Fe 3 O 4 @PEG NPs at a concentration of 20 mg/ ml are evidently promising candidates for their employment as thermal agents in MFH in order to sustain the required range of therapeutic heating for a sufficient amount of time, as shown by the comparison of SAR values [38][39][40][41][42][43].…”

Magnetic nanoparticles (MNP) are anticipated to perform better in terms of thermal conductivity when exposed to alternating magnetic fields (AMF). Herein, key parameters for efficient heating are examined in an AMF that is organized and managed by a zero voltage switching (ZVS) and frequency counter system, which has shown great potential for hyperthermia (HT). The present study investigates the set-up of a matched coil coupled with direct current (DC) power and a frequency counter. The set-up technique for inducing HT in magnetic fluid NPs used in in vitro experiments and magnetic fluid calorimetric applications is advanced. Superparamagnetic iron oxide nanoparticles Fe3O4 (SPIONs) was prepared by the sonochemical method and coated with polyethylene glycol (Fe3O4@PEG). Our sample Fe3O4@PEG crystallized nano-size with an average particle size of 14 nm, and high magnetic saturation (MS) about 49 emu/g. The MNPs exposed to AMF at 300 kHz exhibited the highest thermal values (42–45 °C). The specific absorption rate values of 188, 217, and 234 W/g for the NP concentrations of 5, 10, and 20 mg/ml, respectively reveal the improvement of our set-up to enhance the SPIONs as a thermal agent.

When sealing liquids with magnetic fluid, the interfacial stability problem caused by the interaction between the magnetic fluid and the sealed liquid leads to poor sealing performance. Centrifugal force is generated by the rotation of the sealed liquid in the back blade seal, which forms back pressure to reduce the load of the seal or prevents the sealed liquid from leaking. To reduce the influence of the shaft speed on the sealing performance, a combined magnetic fluid and back blade seal was designed for sealing liquids and a combined seal experiment stand was set up. Theoretical and experimental studies were carried out. The results showed that under a higher shaft speed, the combined seal structure had better sealing performance in which the back blade seal played the main role; the magnetic fluid seal played a major role in stopping and lowering the speed to prevent seal leakage. The combined seal could run stably under different shaft speeds.
