  text: Gadolinium silicide (Gd5Si4) nanoparticles are an interesting class of materials
    due to their high magnetization, low Curie temperature, low toxicity in biological
    environments and their multifunctional properties. We report the magnetic and
    magnetothermal properties of gadolinium silicide (Gd5Si4) nanoparticles prepared
    by surfactant-assisted ball milling of arc melted bulk ingots of the compound.
    Using different milling times and speeds, a wide range of crystallite sizes (13–43
    nm) could be produced and a reduction in Curie temperature (TC) from 340 K to
    317 K was achieved, making these nanoparticles suitable for self-controlled magnetic
    hyperthermia applications. The magnetothermal effect was measured in applied AC
    magnetic fields of amplitude 164–239 Oe and frequencies 163–519 kHz. All particles
    showed magnetic heating with a strong dependence of the specific absorption rate
    (SAR) on the average crystallite size. The highest SAR of 3.7 W g−1 was measured
    for 43 nm sized nanoparticles of Gd5Si4. The high SAR and low TC, (within the
    therapeutic range for magnetothermal therapy) makes the Gd5Si4 behave like self-regulating
    heat switches that would be suitable for self-controlled magnetic hyperthermia
    applications after biocompatibility and cytotoxicity tests.

  text: A new organic–inorganic ferroelectric hybrid capacitor designed by uniformly
    incorporating surface modified monodisperse 15 nm ferroelectric BaTiO3 nanocubes
    into non-polar polymer blends of poly(methyl methacrylate) (PMMA) polymer and
    acrylonitrile-butadiene-styrene (ABS) terpolymer is described. The investigation
    of spatial distribution of nanofillers via a non-distractive thermal pulse method
    illustrates that the surface functionalization of nanocubes plays a key role in
    the uniform distribution of charge polarization within the polymer matrix. The
    discharged energy density of the nanocomposite with 30 vol% BaTiO3 nanocubes is
    ∼44 × 10−3 J cm−3, which is almost six times higher than that of the neat polymer.
    The facile processing, along with the superior mechanical and electrical properties
    of the BaTiO3/PMMA–ABS nanocomposites make them suitable for implementation into
    capacitive electrical energy storage devices.
