Abstract
Superparamagnetic iron oxide nanoparticles (SPIONs) are a promising tool for biomedical applications, including drug delivery, imaging, and magnetic hyperthermia. However, their tendency to agglomerate limits their performance efficiency. To overcome this limitation, a coating can be applied during or after synthesis. This work investigates the effect of three biocompatible coatings, namely sodium citrate, (3-aminopropyl)triethoxysilane (APTES), and dextran, on controlling the agglomeration of iron oxide nanoparticles. Various experimental techniques were used to characterize the structural and magnetic properties of the coated nanoparticles, including cryogenic transmission electron microscopy (cryo-TEM), magnetometry, Mössbauer spectroscopy, and small-angle X-ray and neutron scattering. The results indicate that the coatings effectively stabilize the nanoparticles, leading to clusters of different sizes that modify their magnetic behaviour due to magnetic inter-particle interactions. The oxidation kinetics of the nanoparticles prepared with the various coating materials were investigated to characterize their oxidation behaviour and stability over time. This research provides valuable insights into the design of an optimized nanoparticle functionalization strategy for biomedical applications.

Abstract
Iron oxide nanoparticles with a wüstite structure have been prepared by thermal decomposition. In air, they undergo a spontaneous transition into a thermodynamically more stable magnetite structure that grows from the surface. The thickness of this magnetite shell increases with time, thereby producing a series of core-shell nanoparticles. We investigated the kinetics of this phase transition in 23 nm nanocubes using time-resolved XRD, from which the fractions of individual phases were determined by the Rietveld refinement. This kinetics is described theoretically using three coupled reaction-diffusion master equations for the concentrations of oxygen, wüstite, and magnetite, in which both the diffusion of oxygen and its reaction with wüstite are thermally activated. The coefficients of these terms were adjusted so that the predictions of the model reproduce the XRD data at 298 K and 353 K, whereas the predictive capability of the model was assessed by comparing its predictions with measurements at 403 K.

Abstract
Magnetite affects nitrogen cycle of pig manure (PM) biostabilisation was investigated. Various doses of magnetite (0 % (T1); 2.5 % (T2); 5 % (T3); 7.5 % (T4)) were homogeneously added into PM and wolfberry branch fillings (BF) mixture for a 50-day composting. Compared to T1, total nitrogen (TN) loss in gaseous form increased remarkably by 17.51 %, 56.31 %, and 24.91 %, respectively, in T2-T4. In particular, T3 dramatically increased the cumulative N2O emission but decreased NH3 emissions. However, T2 and T3 enhanced the total nitrogen contents by 7.24 % and 3.09 %. Structural equation models (SEM) analysis indicated that magnetite addition increased the direct and indirect pathways of N2O emission. Further analysis revealed that Ruminofilibacter and N2O emission were significantly correlated, and Pseudomonas played a vital role in nitrogen preservation. Although using 2 % magnetite as an additive could increase the TN content, the obvious increase of N2O emission should be considered in engineering practice.

Abstract
This study was designed to explore the magnetite in maturation and humification during pig manure (PM) and wolfberry branch fillings (BF) composting. Different proportions of magnetite (T1, 0%; T2, 2.5%; T3, 5%; T4, 7.5%;) were blended with PM for 50 days of composting. The findings indicated magnetite amendment has no influence on the maturity, and the 5% ratio significantly promoted humic acid (HA) formation and fulvic acid (FA) decomposition compared to other treatments. Compared to T1, magnetite addition significantly increased CO2 and CH4 emissions by 106.39%-191.69% and 6.88-13.72 times. The further analysis suggested that magnetite improved Ruminofilibacter activity were significantly positively associated with HA, and C emissions. The further PICRUSt 2 analysis showed membrane transport may enhance environmental information processing by magnetite. Overall, these results demonstrated higher organic matter (OM) degradation and HA formation with an additional increase in microbial activity highlighted advantages of using magnetite during PM composting.

RSC Adv 2023; 13:29109-29120.

Abstract
Solid-phase reversible immobilization (SPRI) bead technology is widely used in molecular biology for convenient DNA manipulation. However, commercial SPRI bead kits lack cost advantages and flexibility. It is, therefore, necessary to develop new and alternative cost-effective methods of on-par or better quality. Herein, an easy and cost-effective method is proposed for synthesizing polyacrylic acid-coated iron oxide nanoparticles (PAA-IONPs) through in situ polymerization at lab scale for high-efficiency nucleic acid extraction and size selection. A design of experiment (DoE) approach was used to investigate the influence of iron oxide nanoparticles (IONPs), acrylic acid (AA) monomer, and sodium dodecyl sulfate (SDS) surfactant amounts on the sizes and carboxyl group densities of PAA-IONPs. Thorough characterization by thermogravimetric analysis (TGA), attenuated total reflection Fourier-transform infrared spectroscopy (ATR-FTIR) and vibrating sample magnetometry (VSM) highlights the importance of a low starting pH achieved by a high ratio of AA/IONPs, to yield the largest sizes (554 nm) and highest carboxyl group densities (2.13 mmol g-1) obtained in this study. An efficient DNA purification strategy is then presented using homemade beads-suspension buffer and optimized bead concentrations (17% PEG 8000, 2.5 M NaCl, and 3 mg mL-1 PAA-IONPs). This method shows comparable performance to the control (AMPure XP beads) for DNA recovery. An adjustable PAA-IONPs DNA purification system was also developed to be used for DNA-size selection at low DNA amounts (50-100 ng) with a high degree of resolution and recovery. In conclusion, this work offers an optimized PAA-IONPs synthesis protocol and a flexible DNA purification approach that will enable researchers to manipulate DNA under various conditions, holding the significant potential to benefit future molecular biology research and diagnostics.

Effects of food-grade iron(III) oxide nanoparticles on cecal digesta- and mucosa-associated microbiota and short-chain fatty acids in rats. BIOSCIENCE OF MICROBIOTA, FOOD AND HEALTH 2023; 43:43-54.

Abstract
Although iron(III) oxide nanoparticles (IONPs) are widely used in diverse applications ranging from food to biomedicine, the effects of IONPs on different locations of gut microbiota and short-chain fatty acids (SCFAs) are unclear. So, a subacute repeated oral toxicity study on Sprague Dawley (SD) rats was performed, administering low (50 mg/kg·bw), medium (100 mg/kg·bw), and high (200 mg/kg·bw) doses of IONPs. In this study, we found that a high dose of IONPs increased animal weight, and 16S rRNA sequencing revealed that IONPs caused intestinal flora disorders in both the cecal digesta- and mucosa-associated microbiota. However, only high-dose IONP exposure changed the abundance and composition of the mucosa-associated microbiota. IONPs increased the relative abundances of Firmicutes, Ruminococcaceae_UCG-014, Ruminiclostridium_9, Romboutsia, and Bilophila and decreased the relative abundance of Bifidobacterium, and many of these microorganisms are associated with weight gain, obesity, inflammation, diabetes, and mucosal damage. Functional analysis showed that changes in the gut microbiota induced by a high dose of IONPs were mainly related to metabolism, infection, immune, and endocrine disease functions. IONPs significantly elevated the levels of valeric, isobutyric, and isovaleric acid, promoting the absorption of iron. This is the first description of intestinal microbiota dysbiosis in SD rats caused by IONPs, and the effects and mechanisms of action of IONPs on intestinal and host health need to be further studied and confirmed.
