β-crystals aied greater energy absorbing ethylene–propylene rubber in polypropylene blends for outstanding low-temperature toughness
Published 2025-01-01“…The addition of TMB-5 provides numerous nucleation sites that facilitate the β-crystallization of polypropylene, leading to an increased content of β-crystals and a reduction in crystal grain size. Broadband dielectric relaxation spectroscopy shows that the constrained relaxation of EPR near the crystals shifts to higher temperatures with the formation of β-crystals. …”

Structural and electronic features enabling delocalized charge-carriers in CuSbSe 2
Published 2025-01-01“…Using a combination of theory and experiment, the critical enabling factors are found to be: 1) having a layered structure, which allows distortions to the unit cell during the propagation of an acoustic wave to be relaxed in the interlayer gaps, with minimal changes in bond length, thus limiting deformation potentials; 2) favourable quasi-bonding interactions across the interlayer gap giving rise to higher electronic dimensionality; 3) Born effective charges not being anomalously high, which, combined with the small bandgap ( $$\le$$ ≤ 1.2 eV), result in a low ionic contribution to the dielectric constant compared to the electronic contribution, thus reducing the strength of Fröhlich coupling. …”
