Magnetic nanoparticles (MNPs) are widely used materials for biomedical applications owing to their intriguing chemical, biological and magnetic properties. The evolution of MNP based (such as hyperthermia treatment drug delivery) could be advanced using nanofluids (MNFs) designed with a biocompatible surface coating strategy. This study presents the first report on loading/release capability MN...

Chemical looping gasification (CLG) is an effective coal utilization technology. In this work, the CLG of bituminite was investigated through fixed-bed batch experiments using NiFe2O4 oxygen carrier (OC) to achieve high-quality syngas. The changes in phase during chemical reaction and mechanism were explored. results show that elevated temperature adding a fraction steam facilitate reaction. Ad...

Nanosized Ni ferrite has been prepared by an ecofriendly green synthesis approach based on the self-combustion method. In this route, egg white as a fuel was employed with two different amounts (3 and 10 mL). The XRD results display formation of stoichiometric NiFe2O4-type inverse spinel structure lattice parameter located at 0.8284 nm 0.8322 nm. Additionally, nickel ferrites’ typical crystalli...

We report the first occurrence of a natural quasicrystal with decagonal symmetry. The quasicrystal, with composition Al71Ni24Fe5, was discovered in the Khatyrka meteorite, a recently described CV3 carbonaceous chondrite. Icosahedrite, Al63Cu24Fe13, the first natural quasicrystal to be identified, was found in the same meteorite. The new quasicrystal was found associated with steinhardtite (Al38...

This article reports on the magnetic properties of interacting uncoated nickel ferrite (NiFe2O4) nanoparticles synthesized through an aerosol levitation-jet technique. A comprehensive set of samples with different compositions of background gas and metal precursors, as well as applied electric field intensities, has been studied. Nanoparticles prepared under a field of 210 kV m(-1) show moderat...
