    Antimicrobial and biodegradable PVA/rutin/CuO nanocomposite film for garlic preservation

    FT-IR analysis

    The FTIR spectrum of pure PVA film, as shown in Fig. 1, displays characteristic absorption bands corresponding to its functional groups. A broad and intense absorption peak observed at 3287 cm−1 is attributed to the stretching…

  • Critical fluctuations and noise spectra in two-dimensional Fe3GeTe2 magnets

    Critical fluctuations and noise spectra in two-dimensional Fe3GeTe2 magnets

    We investigate the critical fluctuations in Fe3GeTe2 (hereafter abbreviated as FGT), a van der Waals magnet exhibiting a paramagnetic-ferromagnetic phase transition. FGT is an exfoliable magnet that retains robust ferromagnetism with strong…
