Abstract
Superparamagnetic magnetite nanoparticles have been central to numerous investigations in the past few decades for their use in many applications, such as drug delivery, medical diagnostics, magnetic separation, and material science. However, the properties of single magnetic nanoparticles are sometimes not sufficient to accomplish tasks where a strong magnetic response is required. In light of this, aggregated magnetite nanoparticles have been proposed as an alternative advanced material, which may expand and combine some of the advantages of single magnetic nanoparticles, including superparamagnetism, with an enhanced magnetic moment and increased colloidal stability. This review comprehensively discusses the current literature on aggregates made of magnetic iron oxide nanoparticles. This review is divided into three sections. First, the current synthetic strategies for magnetite nanoparticle aggregates are discussed, together with the influence of different stabilizers on the primary crystals and the final aggregate size and morphology. The second section is dedicated to computational approaches, such as density functional methods (which permit accurate predictions of electronic and magnetic properties and shed light on the behavior of surfactant molecules on iron oxide surfaces) and molecular dynamics simulations (which provide additional insight into the influence of ligands on the surface chemistry of iron oxide nanocrystals). The last section discusses current and possible future applications of iron oxide magnetic aggregates, including wastewater treatment, water purification, medical applications, and magnetic aggregates for materials displaying structural colors.

Abstract
Using the ab initio molecular metadynamics method, the adsorption of the structure of 1-hydroxyethane-1,1-diphosphonic acid (HEDP) on the Fe3O4 surface and subsequent detachment of Fe atoms from the surface were simulated, and the dissolution mechanism by which HEDP dissolves Fe3O4 scale at room temperature while other organic acids cannot was elucidated. The adsorbed hydroxyl groups, water and HEDP on the Fe3O4 surface play a synergistic role in detaching the Fe ions, which increases the coordination number of the Fe atoms and weakens the original Fe-O bond strength. In addition, the strong coordination ability and flexible molecular structure of HEDP also facilitate dissolution of Fe3O4 scale by breaking down the chemical bonds and forming Fe-HEDP complexes. The free energy surface for the dissolution reaction shows a low barrier, and the descaling reaction is easily accomplished.

Abstract
PEGylation of metal oxide nanoparticles is the common approach to improve their biocompatibility and in vivo circulation time. In this work, we present a combined experimental and theoretical study to determine the operating condition that guarantee very high grafting densities, which are desirable in any biomedical application. Moreover, we present an insightful conformational analysis spanning different coverage regimes and increasing polymer chain lengths. Based on 13C NMR measurements and molecular dynamics simulations, we show that classical and popular models of polymer conformation on surfaces fail in determining the mushroom-to-brush transition point and prove that it actually takes place only at rather high grafting density values.

Abstract
Magnetite (Fe₃O₄) nanoparticles are widely used in multiple biomedical applications due to their magnetic properties depending on the size, shape and organization of the crystals. However, the crystal growth and morphology of Fe₃O₄ nanoparticles remain difficult to control without using organic solvent or a high temperature. Inspired by the natural biomineralization process, a 14-mer bi-functional copolypeptide, leveraging the affinity of binding Fe₃O₄ together with targeting ovarian cancer cell A2780, was used as a template in the biomimetic mineralization of magnetite. Alongside this, a ginger extract was applied as an antioxidant and a size-conditioning agent of Fe₃O₄ crystals. As a result of the cooperative effects of the peptide and the ginger extract, the size and dispersibility of Fe₃O₄ were controlled based on the interaction of the amino acid and the ginger extract. Our study also demonstrated that the obtained particles with superparamagnetism could selectively be taken up by A2780 cells. In summary, the Fe₃O₄-QY-G nanoparticles may have potential applications in targeting tumor therapy or angiography.

Abstract
The diffusion of polystyrene (PS) polymer chains from a hydroxy (-OH)-terminated Si surface with different grafting densities φG is studied based on all-atom simulation. Our particular attention is paid to the impact of the attractive substrate on the diffusive and configurational properties of PS. Our simulation results uncover a very novel and unexpected modification to polymer diffusion with the increment of φG, namely, the diffusion is slowed down most significantly from a substrate with moderate grafting densities, while in lower or full grafting cases, the diffusive dynamics is even facilitated rather than retarded. The underlying mechanism is investigated in terms of energy and conformational change in detail. Surprisingly, we obtain a consistent scenario for diffusion. Under moderate grafting densities, the energy required to be overcome for diffusion is relatively large. In addition, PS chains are more likely to be in a stretched configuration subject to a slower relaxation. These facts can account for the hindered diffusion. While under lower or full grafting densities, the energy required for diffusion becomes even smaller than the ungrafted situation. Also, PS chains prefer a shrinking configuration undergoing faster relaxation. Consequently, the diffusion of PS is reasonably promoted.

Abstract
A series of copper oxide supported on Fe3O4/ZnO with molar ratio of Fe3O4:ZnO:CuO varies from 1:1:1 to 1:1:5 were prepared by sol-gel method. X-ray diffraction, field emission scanning electron microscope, energy-dispersive X-ray spectroscopy, UV-visible diffuse reflectance spectroscopy and vibrating sample magnetometer were used to characterize the as prepared Fe3O4/ZnO/CuO hybrid nanoparticles. The results show that Fe3O4/ZnO/CuO hybrid nanoparticles consist of cubic spinel Fe3O4, hexagonal wurtzite ZnO and monoclinic CuO. All prepared samples show ferromagnetic behavior. The photocatalytic activities of these hybrid nanoparticles under visible light irradiation were evaluated by the degradation of malachite green. The results revealed that hybrid nanoparticles exhibited higher photocatalytic activities than pure nanoparticles.

Abstract
![]()
A one-pot
synthetic methodology for fabricating stimuli-responsive
hemicellulose-based hydrogels was developed that consists of the in
situ formation of magnetic iron oxide (Fe3O4) nanoparticles during the covalent cross-linking of O-acetyl-galactoglucomannan
(AcGGM). The Fe3O4 nanoparticle content controlled
the thermal stability, macrostructure, swelling behavior, and magnetization
of the hybrid hydrogels. In addition, the magnetic field-responsive
hemicellulose hydrogels (MFRHHs) exhibited excellent adsorption and
controlled release profiles with bovine serum albumin (BSA) as the
model drug. Therefore, the MFRHHs have great potential to be utilized
in the biomedical field for tissue engineering applications, controlled
drug delivery, and magnetically assisted bioseparation. Magnetic field-responsive
hemicellulose hydrogels, prepared using a straightforward one-step
process, expand the applications of biomass-derived polysaccharides
by combining the renewability of hemicellulose and the magnetism of
Fe3O4 nanoparticles.
