Abstract:
The PVP/Fe3O4 composite nanofibers with different Fe3O4 nanoparticle loading were obtained by electrospinning. The characterization and performance analysis of the composite nanofibers were studied by scanning electron microscopy (SEM), X-Ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analysis (TGA) and antistatic fabric instrument. The results showed that the average diameter of PVP/Fe3O4 composite nanofibers is smaller than that of pure PVP. At 5wt% Fe3O4 nanoparticle loading, the coefficient of variation CV value was low, while the composite nanofiber diame

In this study, we synthesized Ag/Fe3O4 nanoparticles through the co-precipitation method, designating them as S1, S2, and S3 based on varying reaction times (RT) of 60, 30, and 15 minutes, respectively. The synthesized nanoparticles underwent microbiological tests and minimal inhibitory concentration (MIC) assays to assess their antibacterial potential against a spectrum of bacteria. Building upon this, S2 exhibited superior antibacterial efficacy compared to both S1 and S3. Also, structural elucidation of Ag/Fe3O4 nanoparticles was achieved through a comprehensive analysis using UV-visible sp

Abstract:
Magnetic nanoparticle hyperthermia has potential to achieve optimal therapeutic results due to its ability to deliver adequate heating power to irregular and/or deep-seated tumor at low magnetic field frequency and amplitude [1]. Iron oxides magnetite Fe3O4 and maghemite γ-Fe2O3 nanoparticles are the most studied to date [2] due to their biocompatibilty [3] for hyperthermia application. The heat generated by the particles when exposed to an external alternating magnetic field is mainly due to the Néel relaxation mechanism and/or Brownian motion of the particles [4].

Abstract. In recent years, green technologies have been extensively developed, including adsorption technology. In industrial installations, swing adsorptions are favoured for its continuous process. It also posed a large energy demands of almost 40% of overall energy supply. In a temperature swing adsorption (TSA) process, the purging or regeneration phase of the bed requires external heat, whether it to be from steam or hot gas, which largely contributed to the high demand. Hence, an extension of temperature swing adsorption was introduced to overcome the issue by using magnetize particles t

Abstract The capability of commercial nanoparticles to perform as foam stabilizer were investigated at reservoir temperature of 96°C. Al2O3, Fe3O4, Co3O4, CuO, MgO, NiO, ZrO2, ZnO and SiO2 nanoparticles that were characterized using XRD, FTIR, FESEM-EDX, TEM and PSA, were blended in the in-house formulated surfactant named IVF respectively at a particular ratio. The test was performed with and without the presence of reservoir crude oil. Results showed that formulation with nanoparticles enhanced foam stability by having longer foam half-life than the IVF surfactant alone, especially in the ab
