    • Cohesive collisions of particles in liquid media studied by CFD-DEM, video tracking, and Positron Emission Particle Tracking 

      Saparbayeva, Nazerke; Chang, Yu-Fen; Kosinski, Pawel Jan; hoffmann, alex christian; Balakin, Boris; Struchalin, Pavel (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-18)
      This paper investigates the cohesive collision of ice in an oil phase at temperatures ranging from −15.7 °C to −0.3 °C. The new information on the coefficient of restitution (COR) was obtained using three different velocity measurement methods: high-speed experimental video recording, Positron Emission Particle Tracking (PEPT), and numerical simulations. A new type of PEPT tracer was developed for ...

    • Development of an imaging method for in vivo single-cell tracking under high-noise conditions: a proof of principle 

      Chang, Yu-Fen; Struchalin, Pavel; Næss, Bodil; Adamsen, Tom Christian Holm; Balakin, Boris (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-21)
      This paper reports the development of a positron imaging method for in vivo single-cell tracking under high-noise conditions. Following biological processes spatially and temporally at a single-cell level in a living organism is desirable for inquiring into the relationships between the behaviours and properties of cells. Positron-emitting radionuclides enable detecting and following radioactivity-labelled ...

    • Novel bio-compatible tracers for Positron Emission Particle Tracking 

      Chang, Yu-Fen; Balakin, Boris (Conference object; Konferansebidrag, 2020-09)
      To study the flow of objects (tracers) in opaque flow processes, the PEPT (positron emission particle tracking) technique is utilized. The PEPT technique is based on the same principle of PET (positron emission tomography) which detects the characteristic back-to-back gamma pairs caused by positron-electron annihilation. The annihilation takes place within a few millimeters around the tracers labeled ...

    • Novel Bio-compatible Tracers for Positron Emission Particle Tracking 

      Chang, Yu-Fen; Balakin, Boris (Journal article; Tidsskriftartikkel; Peer reviewed, 2020)
      To study the flow of objects in opaque flow processes, the PEPT (positron emission particle tracking) technique may be utilized. The PEPT technique is based on the same principle of positron emission tomography (PET). Both techniques detect the characteristic back-to-back gamma pairs caused by positron-electron annihilation. PEPT allows tracking of β+ - activated objects (tracers) with high spatial ...
