Muonic He (μHe) is a hydrogen-like atom composed of a helium atom with one of its electrons replaced by a negative muon. Measurements of the ground-state hyperfine structure (HFS) interval of the μHe atom is a sensitive tool to test the three-body atomic system, bound-state quantum electrodynamics (QED) theory, and determine fundamental constants of the negative muon magnetic moment and mass. It allows a test of the CPT theorem in muons by comparing these constants with positive muons. Precise measurements of the ground-state HFS interval using a microwave magnetic resonance technique are now in progress at J-PARC by the MuSEUM collaboration. Furthermore, a new experimental approach to recover the muon polarization lost during the muon cascade process is being investigated by repolarizing μHe atoms using a spin-exchange optical pumping (SEOP) technique. The first laser repolarization experiment was recently performed. An overview of the different features of these new μHe atom HFS measurements and the latest results are presented. © The Author(s), under exclusive licence to Springer Nature Switzerland AG 2024.

Porous Poly(vinylidene fluoride-co-hexafluoropropylene)/copper oxide nanocomposite membranes for piezoelectric strain sensing

The emerging field of porous piezoelectric strain sensors attracted a wide range of applications in healthcare monitoring, wearable electronics, and other dynamic applications due to their durability, high sensitivity, and real-time monitoring. This study presents the development of porous poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)/copper oxide (CuO) nanocomposite membranes for piezoelectric strain sensing. The morphology and the dispersion of CuO nanoparticles and nanofibers in PVDF piezoelectric films with different nano-CuO contents are studied by X-ray diffraction, Fourier transform infrared spectrum, scanning electron microscopy and dielectric studies. The PVDF-HFP acts as a scaffold, allowing ions to flow within the porous percolated channels, resulting in a highly robust membrane with desired dielectric properties. The DMA studies enhanced the strain sensing performance of the 3.5 and 7 wt.% CuO nanofibers loaded with PVDF-HFP membranes compared with the 3.5 and 7 wt.% CuO nanoparticles and pristine membranes. The dielectric properties of the composites also showed high storage values for the CuO/PVDF-HFP samples compared to the pristine polymer. Moreover, the surface water contact angles of the membranes have slightly increased after loading the nanomaterial into the PVDF-HFP matrix, which strongly influenced the surface energies, indicating hydrophobicity. The current study, thus, demonstrates the piezoelectric strain sensing devices made from PVDF-HFP/CuO nanofibers for humid atmospheres. © The Author(s) 2025.
