They can exhibit dielectric polarization induced by the magnetic field, a magnetization under an electric field. A strong ME effect requires the simultaneous presence of magnetic moments and electric dipoles. In this work, three phase composites are prepared from <i>β</i> phase Polyvinylidene fluoride (PVDF) and polyurethane (PU) based composites. The two following configurations were studied. They differ by the ferromagnetic or diamagnetic character of the particles added to the polyurethane: PU + 2%wt ferromagnetic Fe₃O₄ / PVDF / PU + 2%wt Fe₃O₄ (PVDF/ferro PU) and PU + 10%wt diamagnetic Bi₂O₃ / PVDF / PU + 10%wt Bi₂O₃ (PVDF/dia PU). The bi-stretched PVDF monolayer sample is used to evaluate the role of the magnetostrictive layer on the magnetoelectric current. The variation of the ME current versus the bias magnetic induction, and the phase between the current and the magnetic induction, suggests the existence of two types of ME coefficients and the complex nature of them. A simple model was used to represent the magnitude of the current and the phase shift, and the experimental and modeled data are in good agreement. The biggest linear ME coefficient was obtained with multilayers prepared with diamagnetic particles. Concerning the bilinear ME coefficient, the largest value was obtained for the system with ferromagnetic particles. The PVDF monolayer also showed a magnetoelectric effect due to the eddy current.

Their structure, morphology, magnetic/microwave properties, and hyperfine interactions have been investigated via X-ray diffractometry (XRD), Scanning/Transmission electron microscopies (SEM/TEM), High resolution transmission electron microscopy (HR-TEM), Vibrating sample magnetometer (VSM), microwave absorption analyzer, and Moss spectroscopy techniques. The single-phase composition (purity of the products) and crystallinity of all products were verified by Energy X-ray Spectrophotometer (EDX) and XRD. The crystallite size (D) of the products is within the range of 14–24 nm. The magnetization curves were performed via a VSM device at ambient (300 K (RT)) and low (10 K), which indicate hard magnetic features with ferrimagnetic behavior for each of the as-prepared Ho→NiCoFe NSFs. The rise in Ho³⁺ substituting content causes a reduction in Ms, which is attributed to the deterioration of A-B exchange interactions and redistribution of cations among A and B sites. Contrarily, the coercivity increases with the rise in Ho³⁺ substituting content, which might be caused by the changes in cationic distribution at A and B sublattices, lattice distortions, reduction in crystallites/grains size, and rise in the number of grain boundaries. Other magnetic parameters were also determined, discussed, and correlated with structural and morphological changes. The Mössbauer spectra consisted of five magnetic sextets for all samples.

Further electrochemical studies have shown that the high electronegativity of halogens effectively promotes the diffusion ability of oxygen ions in the lattice, thus enhancing the electrical conductivity. The ionic conductivity of F, Cl, and Br-doped SDC electrolytes is significantly higher in the temperature range of 475 to 550 °C compared to Br-doped SDC.

To circumvent the reliance on precious metals, it is imperative to attain a high degree of selectivity towards formic acid (HCOOH) through the regulation of Cu metal. Zinc (Zn), being cost-effective and possessing favorable binding energy towards *COOH, emerges as a promising alternative. To further augment the catalytic activity, we employed the electrostatic self-adsorption capability of Ti₃C₂T_xMXene to anchor a Cu-Zn bimetallic structure onto its surface. The results demonstrate that the Cu-Zn bimetallic structure is anchored to the Ti vacancies and coupled with the surface functional groups of MXene. The incorporation of Zn markedly enhances the electron transfer to Cu, leading to a notable 87% selectivity for formic acid and a remarkable stability of 16 h.

But the friction mechanisms of HMX single crystals remain elusive. Classical continuum mechanics faces challenges in modeling discontinuities. In contrast, peridynamic (PD) theory has emerged as an effective approach for investigating discontinuous phenomena such as damage evolution. In this study, a frictional contact model for HMX crystals is developed based on the state-based PD theory. The effects of indenter shape, size, scratching depth and scratching velocity on the tribological response of HMX crystals, particularly regarding damage and crack propagation, are investigated. The results indicate that the tribological response is insensitive to changes in scratching velocity. As the scratching depth increases, longer lateral cracks develop for both the spherical and conical indenters, but the median crack propagation depth increases for only the spherical indenter. And the combined action of radial and lateral cracks plays a crucial role in debris peeling. It is also found that increasing the diameter of the spherical indenter results in more shear cracks and rougher scratch surfaces, without affecting the depth of tensile crack propagation. In addition, the normalized material removal volume and its depth sensitivity are greater for the spherical indenter than for the conical indenter.
