Copper-64 radiopharmaceuticals for theranostics of hypoxic tumors
(Doctoral theses at NTNU;2023:318, Doctoral thesis, 2023)English summary Tumor hypoxia (oxygen deficiency) is a poor indicator in cancer as it associates with disease progression, recurrence, metastasis, and treatment resistance. Hypoxia occurs in most solid tumors, however, ... -
Design and fabrication of (Cr + N) co-doped TiO2 films with a continuous compositional spread
(Doctoral theses at NTNU;2023:228, Doctoral thesis, 2023)Intermediate band solar cells (IBSCs) have a theoretically conversion efficiency that is approximately 50 % higher than for the solar cell technologies dominating today. IBSCs are based on a new type of materials, where ... -
Diffractive X-ray Tomography of Oriented Mineralized Structures Doctoral thesis in Hierarchical Materials
(Doctoral theses at NTNU;2021:112, Doctoral thesis, 2021)Many materials around us in everyday life have a hierarchical structure, meaning that defining structural features are found at multiple length scales, often ranging from the molecular to the macroscopic scale, together ... -
