Summary: A PMMA bone cement formulation containing TiO2 and Fe3O4 was proposed for treatment of bone defects caused by metastatic bone tumors, with the ability to be used in magnetic hyperthermia. Samples with 15% or higher TiO2 concentration formed apatite on their surfaces within 14 days in a simulated body fluid, while samples with 25% and 30% Fe3O4 reached temperatures over 42°C under specific AC magnetic fields, making them suitable for hyperthermia treatment.

Summary: We conducted polarized small-angle and wide-angle neutron scattering experiments on 420 nm-sized hollow Fe3O4 spherical particles. Each particle is a mesocrystal composed of small nanoparticles with the same crystallographic orientation. We used polarized neutron experiments to evaluate the magnetic correlations during magnetization process. Our results show that the perpendicular magnetization component maximizes around zero applied field, while the parallel component minimizes, both below and above the Verwey transition temperature. Our calculations suggest the reorientation of the vortex core towards the magnetocrystalline anisotropy axis at low applied fields. We also found that the magnetic domain length obtained from wide-angle scattering is comparable to the size of the small nanoparticles forming the hollow sphere, indicating that magnetic correlations within the nanoparticles retain during magnetization process.

Summary: The study successfully investigated the application of thermosensitive core-shell Fe3O4@PNIPAM nanogels in enhanced oil recovery. The nanogels exhibited high viscosity and low nanofluid mobility ratio at high temperatures, leading to efficient displacement front during EOR. Additional oil recovery of about 25.75% was achieved when the nanofluid was injected at a temperature of 45 degrees C, although a further increase in temperature could result in reduced oil recovery due to nanogel precipitation.

Summary: This study investigated the morphological and structural changes of polymethyl methacrylate-silicon dioxide core-shell particles and hollow SiO2 particles during heat treatment using electron microscopy, infrared spectroscopy, and X-ray diffraction. The polymeric core of the PMMA-SiO2 hybrid particle exhibited an unusual transformation, shrinking through the formation of a spherical cavity when exposed to the electron microscope beam. The process of silica-shell formation occurred in the temperature range of 200-600 degrees C and was accompanied by the loss of vinyl- and OH-groups.

Summary: This article presents the preparation and characterization of ultrafine superparamagnetic Fe3O4 nanoparticles and their composites with the PMMA polymer matrix. The nanofiller particle Fe3O4 is found to have a cubic structure with the space group (Fd 3 m) based on X-ray diffraction studies. The microstructure and elemental compositions of PMMA-Fe(3)O(4) polymer composites are examined using scanning electron microscopy and energy dispersive spectroscopy. The interaction between the filler particles and the functional group of the polymer PMMA is detected by Fourier transform infrared spectroscopy. UV-spectroscopy studies reveal that PMMA-Fe(3)O(4) nanocomposite films exhibit tunable energy band gap properties.

Summary: This study investigates the influence of the introduced TamOn-TiO2/TiO2/Ti multi-interlayer on the microstructure, adhesive, mechanical, and anti-corrosion properties of reactive sputtered tantalum oxide coatings. The inserted multiple interlayers reduce the residual stress in the coating, couple the mechanical performance between the layer and the substrate, and block the continuous growth of penetrating defects in a film with columnar structure. The results provide a workable approach for improving the properties of the tantalum oxide coating on Ti6Al4V alloy for medical applications.

Summary: Salicylaldehyde functionalized chitosan (S-CHIT) was successfully synthesized and attached to the surface of acetylene black paste electrode (ABPE) to construct an electrochemical sensor. The electrochemical behaviors of catechol (CC) and hydroquinone (HQ) on the S-CHIT/ABPE were investigated using cyclic voltammetry (CV) and second-order derivative linear sweep voltammetry (SDLSV). Quantitative determination of CC and HQ was achieved using SDLSV with the oxidation signal. The results demonstrate that S-CHIT/ABPE is a promising electrochemical sensor for the simultaneous detection of CC and HQ.

Summary: A Nb2O5/Mg gradient coating was synthesized on AZ31 magnesium alloy through magnetron sputtering, which showed improved mechanical, anti-wear, and anti-corrosion properties. The coating had an amorphous columnar structure and a gradual change in chemical composition, reducing residual stress and increasing compactness. Compared to a Nb2O5 single-layer film, the gradient coating exhibited increased adhesion, hardness, elastic modulus, and reduced wear rate. Moreover, it showed better corrosion resistance. This study provides a strategy for enhancing ceramic coatings on magnesium alloy for medical applications.
