The magnetic properties of core/shell nanoparticles (NPs) depend on the various parameters, including the magnetic interactions, but these effects have not been well studied. Here, we systematically investigated the structure and magnetic properties of Fe3O4@CoFe2O4 core/shell NPs. X-ray diffraction (XRD), scanning electron microscopy (SEM), and scanning transmission electron microscopy (STEM) confirmed the formation of Fe3O4@CoFe2O4 core/shell NPs.

In this study, calcite and zeolite minerals, with well-known incombustibility properties, were used together with huntite hydromagnesite as auxiliary minerals to obtain better mechanical properties. In this context, a synergistic effect was created by adding zeolite and calcite to polymer composite systems containing huntite hydromagnesite, and flame retardant polypropylene matrix composites were produced using a twin screw extruder.

The kinetic study was also carried out by studying the adsorption process at different temperatures using these two adsorbents to find the rate of adsorption process, its mechanism and to determine different thermodynamic parameters. For this purpose, different kinetic models were used which include film diffusion, particle diffusion, intraparticle diffusion, Elovich, Lagergren pseudo first order, Lagergren pseudo second order, simple first order and second order equations.

This paper reports on the extraction of microcrystal cellulose from cotton fiber and their application as a reinforcing agent in NR matrix. Microcrystalline cellulose was also grafted with maleic anhydride (MA) so that grafted one can improve interfacial interaction between cellulose and natural rubber. Fillers were incorporated to block natural rubber by two-roll mill dry mixing.
