Nano Fe3o4

Functionalized Janus nanoparticles have received increasing interest due to their anisotropic shape and the particular utility in biomedicine areas. In this work, a simple and efficient method was developed to prepare fluorescent/magnetic composite Janus nanoparticles constituted of fluorescent polyurethane and hydrophobic nano Fe3O4. Two kinds of fluorescent polyurethane prepolymers were synthesized by the copolymerization of fluorescent dye monomers, and the fluorescent/magnetic nanoparticles were fabricated in one-pot via the process of mini-emulsification and self-assembly. The nanostructures of the resulting composite nanoparticles, including core/shell and Janus structure, could be controlled by the phase separation in assembly process according to the result of transmission electron microscopy, whereas the amount of the nonpolar segments of polyurethane played an important role in the particle morphology. The prominent magnetic and fluorescent properties of the Janus nanoparticles were also confirmed by vibrating magnetometer and confocal laser scanning microscope. Furthermore, the Janus nanoparticles featured excellent dispersity, storage stability, and cytocompatibility, which might benefit their potential application in biomedical areas.

It is an effective solution to the problem of agglomeration using the magnetic composite SiO2/(γ-Fe2O3- SiO2) instead of traditional magnetic particles Fe3O4as the core of molecular sieve. The traditional hydrothermal method was utilized by means of adding the magnetic composite particles SiO2/(γ-Fe2O3- SiO2) into the pre-made crystallization liquid. Then, a series of magnetic 4A zeolites with varying contents of SiO2/(γ-Fe2O3- SiO2) were synthesized under the condition of ultrasonic crystallization for 6 hours with the power of 100W and temperature of 70 °C . Afterwards, the characterization tests such as XRD,SEM,TG,IR were carried out; the final result showed that the performance of 4A zeolite molecular sieve with SiO2/(γ-Fe2O3- SiO2) is basically identical with the pure 4A zeolite molecular sieve. The absorption rate was 13.5927μg/g by using the 4A zeolite molecular sieve with SiO2/(γ-Fe2O3- SiO2) for the absorption of mercury.
