EELS and STEM studies of perovskite oxide heterostructures
(Doctoral theses at NTNU;2016:361, Doctoral thesis, 2016)Perovskite oxide heterostructures have attracted much research interest due to a strong coupling between the local crystal structure and the functional properties. Of special interest are the interfaces of thin film systems, ... -
Effect of acoustic cluster therapy (ACT®) combined with chemotherapy in a patient-derived xenograft mouse model of pancreatic cancer
(Peer reviewed; Journal article, 2022)Pancreatic ductal adenocarcinomas respond poorly to chemotherapy, in part due to the dense tumor stroma that hinders drug delivery. Ultrasound (US) in combination with microbubbles has previously shown promise as a means ... -
Effect of acoustic radiation force on displacement of nanoparticles in collagen gels
(Peer reviewed; Journal article, 2020)Penetration of nanoscale therapeutic agents into the extracellular matrix (ECM) of a tumor is a limiting factor for the sufficient delivery of drugs in tumors. Ultrasound (US) in combination with microbubbles causing ... -
Effect of Acoustic Radiation Force on the Distribution of Nanoparticles in Solid Tumors.
(Peer reviewed; Journal article, 2020)Acoustic radiation force (ARF) might improve the distribution of nanoparticles (NPs) in tumors. To study this, tumors growing subcutaneously in mice were exposed to focused ultrasound (FUS) either 15 min or 4 h after the ... -
The effect of addition of the redox mediator dimethylphenazine on the oxygen reaction in porous carbon electrodes for Li/O2 batteries
(Peer reviewed; Journal article, 2023)Secondary Li–O2 batteries are promising due to their potentially high theoretical energy density. However, both the discharge (oxygen reduction reaction, ORR) and the recharge reaction (oxygen evolution reaction, OER) are ... -
