Charge-Transfer-Mediated Boron Magneto-Ionics: Towards Voltage-Driven Multi-Ion Transport. [PDF]
Adv Sci (Weinh)This study demonstrates voltage‐driven multi‐ion transport in FeBO systems, revealing simultaneous motion of B, Fe, and O ions enabled by charge‐transfer effects. By tuning oxidation states through oxygen incorporation, we achieve a transition from electrostatic‐like to electrochemical magneto‐ionic behavior. The findings establish boron magneto‐ionics,

Position-resolved Positron Annihilation Lifetime Spectroscopy [PDF]
Journal of Physics: Conference Series, 2013 A new method which allows for position-resolved positron lifetime spectroscopy studies in extended volume samples is presented. In addition to the existing technique of in-situ production of positrons inside large (cm3) bulk samples using high-energy photons up to 16 MeV from bremsstrahlung production, granular position-sensitive photon detectors have ...

TOT Method for the Disentanglement of Photons in Positron Annihilation Lifetime Spectroscopy
Acta Physica Polonica A, 2020 The Jagiellonian Positron Emission Tomograph (J-PET) is a multidisciplinary device aiming to perform studies in medical field as well as to test the fundamental symmetries. The plastic scintillators offer very good time resolution. Although, due to the low atomic number of the plastic material, the incident photons interact mainly via the Compton ...
