Abstract PVDF is a semicrystalline polymer made up of repeating units ─CH 2 CF ─ monomer and has five crystalline phases, which are α , β γ δ ε ‐phases. However, piezoelectricity dependent on the ‐phase crystalline. Thus, to increase formation ‐phase, CNCs with various weights (1%–5%) incorporated into by using electrospinning method. The influence electrospun PVDF/CNCs investigated analytical methods such as FESEM, FTIR, XRD, universal testing machine (UTM), electrochemical impedance...
Quantized bound states at a vortex core are discretized in YNi 2 B C. By using scanning tunneling spectroscopy with an unprecedented 0.1 nm spatial resolution, we find and identify the localized spectral structure, where addition to first main peak positive low energy, second subpeak coming from fourfold symmetric gap structure is seen inside energy gap. Those features understood solving Bogoliubov–de Gennes equation for fully three-dimensional structure. A particle–hole asymmetric spectrum...
