Summary: This study reports on the adsorption of tetracycline using magnetic chitosan as the adsorbent. The highest adsorption capacity was achieved at pH 7.0, and the efficiency of the adsorbent depended on pH, initial concentration, and dosage. Ionic strength significantly affected the process. The Sips and Elovich models provided the best fit for the experimental data, indicating heterogeneous surface adsorption predominantly through chemical mechanisms. The adsorption of tetracycline was governed by hydrogen bonds and cation-pi interactions, and the incorporation of magnetite on the chitosan surface enhanced its removal efficiency. Thermodynamic parameters suggested a spontaneous and exothermic process. Magnetic chitosan proved to be effective in tetracycline removal even after multiple adsorption/desorption cycles.

Summary: Recently, magnetite nanoparticles (MNPs) have been highly valued for their unique properties and potential in oil spill cleanup. In this study, the surface of MNPs was functionalized using newly synthesized hydrophobic ionic liquids (ILs) and applied for oil spill cleanup. The functionalized MNPs showed high oil removal efficiency even at low MNP ratios. Additionally, MNPs functionalized with GEOA-IL exhibited higher oil removal efficiency compared to those functionalized with GEDA-IL. Furthermore, the functionalized MNPs showed excellent reusability over multiple cycles.

Summary: In this study, cyclodextrin-stabilized magnetic nanoparticles were used to extract Au/Ag nanoparticles as nanometallic pollutants from water. The extraction process relied on the host-guest interactions between the surfactants used for stabilizing the Au/Ag nanoparticles and the CD cavity of the functionalized magnetic nanoparticles. Stronger host-guest interactions were found to be necessary for effective extraction.

Summary: To achieve accurate diagnosis of tumors using MRI, switchable magnetic resonance contrast agents (CAs) that can enhance T-1 and T-2 contrast have been developed based on extremely small iron oxide nanoparticles (ESIONPs). In this study, a hypoxia-responsive ESIONP-based nanocluster, named EAmP, was developed for the first time. EAmP exhibited a T-2-to-T-1 switchable contrast enhancement function, effectively differentiating between normal tissue and tumor tissue. This switchable contrast agent offers high sensitivity and signal-to-noise ratio for the accurate diagnosis of tumors, making it a potential MRI nanoprobe for improving diagnostic accuracy of solid tumors.

Summary: Magnetization is a measurable property of materials that provides information about their electronic structure, phase purity, and impurities. Superparamagnetism, a size-dependent property of magnetic materials, has been underexplored in the field of quantum materials. In this study, a statistical model is used to analyze a dataset of variable-size superparamagnetic Fe3O4 particles. The results show that parameters of the intrinsic probability distribution, such as the maximum susceptibility, are more suitable for describing the superparamagnetic behavior compared to standard measures like saturation magnetization. This analysis has potential applications in synthesis diagnostics and prediction of new properties and functionality.

Summary: In the study, it was found that different coatings did not affect the composition of the protein corona on iron oxide nanoparticles. Enzymes with hydrolase activity in the corona may explain the degradation of coatings when in contact with biological media. Coatings primarily determine the endocytic pathways used for nanoparticle internalization by cells.

Summary: Placing a barrier membrane between an alveolar bone wound and gingival soft tissue is a common and effective method in dentistry. However, combining a barrier membrane with bone-forming substitutes is challenging. In this study, a composite material was developed to prevent epithelial invasion and promote alveolar reconstruction. The introduction of iron oxide nanoparticles enhanced osteogenesis and the scaffold showed promise in facilitating bone regeneration in a rat model.

Summary: Hydrophobic coatings inspired by the lotus effect have gained popularity for their ability to solve various problems. The sol-gel method, utilizing silica, alumina, and titania, is explored as an environmentally friendly approach to produce water-based hydrophobic coatings. This study focuses on producing water-based hydrophobic coatings for cotton and polyester fabrics using a one-step sol-gel method. The coated fabrics exhibited improved hydrophobic properties, altered surface morphologies, and lower air permeability compared to uncoated fabrics. TEOS-PDMS coating provides a promising approach for enhancing the hydrophobic and surface properties of cotton and polyester fabrics.

Summary: Pt/C and SO42-/ZrO2 were used as catalysts for the synthesis of p-aminophenol through the catalytic transfer hydrogenation of nitrobenzene in water with formic acid as the hydrogen source. The optimal Pt loading for PAP selectivity was found to be 1 wt%. The presence of different valence states of Pt affected both the nitrobenzene hydrogenation and formic acid decomposition. Among different solid acid catalysts tested, SO42-/ZrO2 exhibited the highest catalytic activity for p-aminophenol formation. Under the optimized reaction conditions, the conversion of nitrobenzene reached 80.0%, with a selectivity of 47.6% for p-aminophenol.

Summary: The mechanism of the reaction between CO2 and styrene oxide for cyclic carbonate was revealed using density functional theory calculations. The noncatalytic reaction occurred via a concerted mechanism, while in the presence of guanidine and tetrabutylammonium iodide (TBAI) co-catalysts, the epoxide ring-opening by nucleophilic attack of an iodide anion was predicted to be the rate-determining step. Guanidine acted as the H-bond donor to activate styrene oxide, facilitating the reaction with a lower activation barrier.

Summary: Copper nanorods (Cu-NRs) exhibit significant plasmonic behavior and can act as efficient catalysts in redox processes and coupling. A benign decarboxylative approach, utilizing localized surface plasmon resonance (LSPR) assisted catalysis with Cu-NRs, has been developed for the production of alkane analogues from alkyl carboxylic acids under visible light. The catalyst shows a broad substrate scope and high functional group tolerance, without the need for an external oxidant or proton source. A plausible mechanism for this recyclable nano-catalyst has also been proposed based on control experiments.
