Abstract Among the galactic sources that can be detected by KM3NeT detector, we will consider eHWC J1825-134 source recently HAWC telescope. Moreover, RX J1713.7-3946 and show prospects of detection in a fully hadronic lepto-hadronic scenario. Considering IceCube instead, focus on gamma-ray J1907+063 J2019+368. We found at 3 σ or more detector should within reach next decade. Finally, also 2HWC...

Ferroelectric materials have attracted interest for over a hundred years as result of their spontaneous polarization and orientation that can be reversed by the application an external electric field. In addition, degree affected stimuli such vibrations, stress, heat, light. These properties enable ferroelectric to used fabricate nanogenerators, which are devices in energy scavenging applicatio...
