Fermi Arcs Dominating the Electronic Surface Properties of Trigonal PtBi2

open access: yesAdvanced Physics Research, Volume 4, Issue 5, May 2025.
Trigonal PtBi2 is a Weyl semimetal with recently demonstrated surface superconductivity. Scanning tunneling spectroscopy of the quasiparticle interference in the normal state of this material, combined with density functional theory calculations, reveals that the scattering between Fermi arcs dominates the interference spectra, providing conclusive ...

Inter-comparison of boron concentration measurements at INFN-University of Pavia (Italy) and CNEA (Argentina)

open access: yesApplied Radiation and Isotopes, 2015
An inter-comparison of three boron determination techniques was carried out between laboratories from INFN-University of Pavia (Italy) and CNEA (Argentina): alpha spectrometry (alpha-spect), neutron capture radiography (NCR) and quantitative autoradiography (QTA). Samples of different nature were analysed: liquid standards, liver homogenates and tissue
