Abstract Ionic conductive hydrogels (ICHs) integrate the performance and soft nature of tissue‐like materials to imitate features human skin with mechanical sensory traits; thus, they are considered promising substitutes for conventional rigid metallic conductors when fabricating human‐motion sensors. However, simultaneous incorporation excellent stretchability, toughness, ionic conductivity, self‐healing, adhesion via a simple method remains grand challenge. Herein, novel ICH platform is...

Nanosized spinel ferrites MFe 2 O 4 (M = Ni, Co, and Zn) have been prepared by sol‐gel autocombustion method using citric acid as a fuel agent. The materials are characterized X‐ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM). applied for Congo‐Red (CR) dye adsorption batch technique. Different kinetic equilibrium models fitted nonlinear regression to analyze the data. In accordance with Langmuir isotherm, maximum capacity at 293...

Prostate malignancy represents the second leading cause of cancer-specific death among male population worldwide. Herein, enhanced intracellular magnetic fluid hyperthermia is applied in vitro to treat prostate cancer (PCa) cells with minimum invasiveness and toxicity highly specific targeting. We designed optimized novel shape-anisotropic core-shell-shell nanoparticles (i.e., trimagnetic - TMNPs) significant magnetothermal conversion following an exchange coupling effect external...

In this work, we report the synthesis and characterization of three magnetic nanosystems, CoFe2O4, CoFe2O4@ZnFe2O4, CoFe2O4@MnFe2O4, which were developed as potential theranostic agents for hyperthermia resonance imaging (MRI). These nanosystems have been thoroughly characterized by X-ray Diffraction (XRD), Transmission Electron Miscroscopy (TEM), Dark Field-TEM (DF-TEM), Vibrating Sample Magnetometry (VSM), inductive heating, in order to elucidate their structure, morphology, properties....

The development of high-performance protein-imprinted materials is vital to meet the requirements proteomics research but remains a challenge. Herein, new type raspberry-like cytochrome C-imprinted nanoparticle was first designed and fabricated via surface imprinting technology combined with template immobilization strategy. In particular, state-of-the-art metal–organic framework (MOF)/carbon (CN) composites were selected as protein carriers for two advantages: (1) reflected intrinsic...

BaCe x Ti1− O3 (x = 0.06, 0.10, and 0.20) solid solutions were prepared via conventional the solid-state reaction sintered at 1500°C for 4 h, resulting in dense single phase ceramics with homogeneous microstructures. The electric field dependence of permittivity was investigated detail, together ferroelectric–paraelectric transition features. A transformation from normal to relaxor ferroelectrics observed by increasing Ce concentration. For low-Ce content, a substitution on both B site...
