Summary: This research examines the synergistic behavior of magnetorheological elastomers containing nickel and cobalt, along with iron particles as magnetically polarizable fillers, under dynamic shear loading. Experimental investigations were conducted on two different types of magnetorheological elastomers, with varying concentrations of magnetic particles, frequencies, displacement amplitudes, and magnetic field values. The results showed that the stiffness of the elastomers increased with the percentage filler content and frequency, while it decreased with displacement amplitude. The maximum magnetorheological effect was found to be 55.56%. Additionally, it was observed that the elastomer with iron and cobalt exhibited the highest effective stiffness, while the elastomer with iron and nickel displayed the highest magnetorheological effect.

Summary: The tunable mechanical properties and magnetostriction of Magnetoactive (MA) foam have the potential for soft sensor technology development. However, researchers have found that its capabilities are morphologically dependent, and in this work, MA foam was developed with additional capabilities by manipulating the concentration of carbonyl iron particles (CIPs) and the magnetic field. The highly sensitive MA foam could potentially be implemented in future soft sensor systems.

Summary: Nano-water-based drilling fluids (NWBDFs) were prepared using nano-copper oxide (CuO) and multiwalled carbon nanotubes (MWCNTs) as modification materials. The effects of temperature and concentration of the nanoparticles (NPs) on the rheological properties were studied using a rotational rheometer and viscometer. The influence of the two NPs on the filtration properties was investigated using a low-pressure and low-temperature filtration apparatus, as well as a scanning electron microscope (SEM). The study found that MWCNTs with a concentration of 0.05 w/v% exhibited the most significant influence on NWBDFs, improving gel structure stability against temperature and reducing filtration rate. A theoretical model predicting the yield point (YP) and plastic viscosity (PV) as a function of temperature considering the influence of NPs was developed based on DLVO theory.

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: Facial prosthetics require materials with a skin-like feel. This study assessed the effects of adding hydrophobic- and uncoated nano-SiO2 to PDMS and compared them to submicron SiO2-filled materials. The results showed that 15% coated nano-SiO2-filled PDMS had the highest strength and hardness, while 15% submicron coated SiO2-filled materials had the highest translucency. Only the submicron SiO2-filled PDMS materials were altered by outdoor weathering. Fillers provided protection against weathering, but high filler levels resulted in limited stretchability and high hardness, which were seen as downsides for creating a skin-like feel.

Summary: Single-phase lanthanum-modified bismuth ferrite multiferroic ceramics were synthesized using the RLS method, with studies conducted on their phase composition, crystal structure, microstructure, and dielectric properties. The optimal conditions for achieving a perovskite Bi0.9La0.1FeO3 structure were determined, with compacting pressure shown to greatly impact the dielectric constant of the material. The use of the RLS method under varying compacting pressures offers new possibilities for creating multifunctional multiferroics with controlled magnetoelectric coupling.

Summary: The study presents results on magnetoactive elastomers (MAEs) with elastic matrix and embedded ferromagnetic particles. It reports a continuous critical bending induced by magnetic field, mechanical stability loss, and symmetry reduction at the critical point. The magnetization in high-symmetry state is aligned with the magnetic field below the critical point, and torque emerges above it, showing hysteresis in MAE bending related to magneto-rheological effect.

Summary: Temperature-dependent magnetic properties and spin echo decay behavior were investigated for a set of La1-xSrxMnO3 (x = 0.23) nanoparticles (30 nm in diameter) synthesized using the sol-gel method. The study determined characteristic magnetic parameters, such as blocking temperature and effective Curie temperature for the ensemble. Enhanced coercivity and its unusual temperature dependence compared to bulk counterparts were observed, and possible explanations for this phenomenon were discussed. The study concludes that interparticle interactions play a significant role in enhancing the coercivity in the ensembles of substituted manganites.

Summary: In this study, a novel multiferroic-like nanocomposite is designed and obtained using the high-pressure torsion (HPT) method. The obtained results show that the composite consists of exchange-interacting ferroelectric and ferromagnetic phases, and it demonstrates improved magnetic and electrical properties at room temperature. The new composite also exhibits a giant increase in residual polarization with an increase in external high-pressure. These findings suggest that the novel nanocomposite can be used in electronic devices for monitoring ultra-high-pressure and in integrated circuits of high-speed computing nanosystems.

Summary: The principal factors leading to efficient AC field-induced heating of magnetic fluids are determined based on measurements of magnetic and calorimetric properties of NaFeO2 nanoparticles and their fluids. The magnetic behavior and parameters of NaFeO2 nanoparticles are identified, and the relationship between fluid caloric properties and AC magnetic field amplitude and nanoparticle concentration is analyzed. It is found that the heating efficiency of weakly coercive NaFeO2 nanoparticles shows an amplitude threshold character and the heating rate is critically dependent on AC magnetic field amplitude.

Summary: The critical bending deformation and magnetization of a magnetoactive elastomer (MAE) beam with a fixed end in a transverse uniform magnetic field have been studied. The symmetry of the beam shape and the symmetry of the MAE magnetic state change spontaneously after the beam reaches a critical bending. The formation of an angular magnetic state in the beam has a magnetoelastic origin and is characterized by the critical behavior of the mutually related bending and longitudinal effective magnetization of the MAE.
