Luminescence of bound excitons created near sodium impurity ions in KCl:Na single crystals
Published 2025-02-01“…The lifetime of the fast component of cathodoluminescence at 2.8 and 3.1 eV equals 2.4 and 1.7 ns, respectively, at 6 K and even shortens to approximately τ ≈ 0.3 ns at room temperature. At 10 K, photons of 7.6 and 6.7 eV directly form ELFs in the field of single or paired Na+ impurity ions with typical luminescence bands peaked, respectively, at 2.8 eV (el0 (Na+)) and 3.1 eV (el0 (Na+-Na+)). …”

Multi-modality Imaging Identifies Key Times for Annexin V Imaging as an Early Predictor of Therapeutic Outcome
Published 2004-01-01“…To address this issue, we obtained simultaneous in vivo measurements of tumor burden and uptake of radiolabeled annexin V in the syngeneic orthotopic murine BCL 1 lymphoma model using in vivo bioluminescence imaging (BLI) and small animal single-photon emission computed tomography (SPECT). BCL 1 cells labeled for fluorescence and bioluminescence assays (BCL 1 − gfp/luc ) were injected into mice at a dose that leads to progressive disease within two to three weeks. …”

Reflection of two-dimensional surface polaritons by metallic nano-plates on atomically thin crystals
Published 2023-01-01“…Through our rigorous model, we reveal that, for strongly confined 2DSPs having much larger momentum than free space photons, the interaction results in almost total internal reflection of 2DSPs as the radiative coupling of the 2DSPs to free space is negligible. …”

Position for Site-Specific Attachment of a DOTA Chelator to Synthetic Affibody Molecules Has a Different Influence on the Targeting Properties of Ga-Compared to In-Labeled Conjugat...
Published 2014-12-01“…Radiolabeling of Affibody molecules with the positron-emitting nuclide 68 Ga would permit the use of positron emission tomography (PET), providing better resolution, sensitivity, and quantification accuracy than single-photon emission computed tomography (SPECT). The synthetic anti-HER2 Z HER2:S1 Affibody molecule was conjugated with DOTA at the N-terminus, in the middle of helix 3, or at the C-terminus. …”
