Ultrasound for the delivery of a nanocarrier across biological barriers in tumors: impact of cavitation and acoustic radiation force
(Doctoral theses at NTNU;2020:56, Doctoral thesis, 2020)Ultrasound for the delivery of a nanocarrier across biological barriers in tumors: impact of cavitation and acoustic radiation force Although conventional chemotherapy is the still one of the most important treatment ... -
Ultrasound Improves the Delivery and Therapeutic Effect of Nanoparticle-Stabilized Microbubbles in Breast Cancer Xenografts
(Journal article; Peer reviewed, 2017)Compared with conventional chemotherapy, encapsulation of drugs in nanoparticles can improve efficacy and reduce toxicity. However, delivery of nanoparticles is often insufficient and heterogeneous because of various ... -
Ultrasound in Imaging and Delivery of Nanomedicine in Cancer Tissue
(Doctoral thesis at NTNU;2015:27, Doctoral thesis, 2015)Nanotechnology in therapy of solid tumors is a strategy where the cytotoxic drugs are encapsulated into nano-sized particles. It is expected that therapy using nanomedicine will result in both increased specificity of the ... -
Ultrasound radiation force transport of drugs in tumors
(Master thesis, 2013)Chemotherapy effectiveness not only depends on drug penetration extent in target tissues or tumor cells, but also depends on drug suppression extent by the normal tissues and cells. Ultrasound acts as an important role to ... -
Ultrasound radiation force transport of drugs in tumors
(Master thesis, 2013)Delivery of chemotherapeutic agents administered intravenously tosolid tumors tissue in optimal quantities is one of the challenges in theclinic. However, ultrasound improves the delivery of the chemothera-peutic agents ... -
Ultrasound Stimulated Release of Liposomes
(Master thesis, 2008)A prerequisite for successful cancer therapy (drug delivery) is that the cytotoxic agents reach all cancer cells and inactivates them and this requires triggerable release of liposomes in order to delivery a high local ... -
Ultrasound-mediated delivery and distribution of polymeric nanoparticles in the normal brain parenchyma of a metastatic brain tumour model
(Journal article; Peer reviewed, 2018)The treatment of brain diseases is hindered by the blood-brain barrier (BBB) preventing most drugs from entering the brain. Focused ultrasound (FUS) with microbubbles can open the BBB safely and reversibly. Systemic drug ... -
Ultrasound-mediated delivery enhances therapeutic efficacy of MMP sensitive liposomes
(Peer reviewed; Journal article, 2020)To improve therapeutic efficacy of nanocarrier drug delivery systems, it is essential to improve their uptake and penetration in tumour tissue, enhance cellular uptake and ensure efficient drug release at the tumour site. ... -
Ultrasound-Mediated Delivery of Chemotherapy into the Transgenic Adenocarcinoma of the Mouse Prostate Model
(Peer reviewed; Journal article, 2020)Ultrasound (US) in combination with microbubbles (MB) has had promising results in improving delivery of chemotherapeutic agents. However, most studies are done in immunodeficient mice with xenografted tumors. We used two ... -
Ultrasound-mediated delivery of nanomedicine across biological barriers - for improved treatment of cancer and diseases in the brain
(Doctoral theses at NTNU;2017:190, Doctoral thesis, 2017)Despite major progress in the field of cancer research during the last decades, cancer remains a leading cause of death worldwide. Treatment with conventional chemotherapy is limited by inadequate delivery to the tumor and ... -
Unconventional Meissner screening induced by chiral molecules in a conventional superconductor
(Peer reviewed; Journal article, 2021)The coupling of a superconductor (SC) to a different material often results in a system with unconventional superconducting properties. A conventional SC is a perfect diamagnet expelling magnetic fields out of its volume, ... -
Unconventional Superconductivity on a Topological Insulator
(Journal article; Peer reviewed, 2010)We study proximity-induced superconductivity on the surface of a topological insulator (TI), focusing on unconventional pairing. We find that the excitation spectrum becomes gapless for any spin-triplet pairing, such that ... -
Understanding Capacity Fading of MgH2 Conversion-Type Anodes via Structural Morphology Changes and Electrochemical Impedance
(Journal article; Peer reviewed, 2018)Previous studies have demonstrated that MgH2 is a promising conversion-type anode toward Li with high capacity (2037 mAh/g) and low discharge/charge overpotential hysteresis. A major challenge is the capacity loss after a ... -
Understanding complementarity-based security proofs of quantum key distribution with imperfect sources
(Master thesis, 2017)We present a study of modern security proofs of quantum key distribution based on complementarity. This is a quantum communication protocol allowing for provable, unconditional security, although there is still a gap between ... -
Understanding crystallization in alginate-calcium phosphate composites
(Doctoral theses at NTNU;2017:18, Doctoral thesis, 2017)Summary of thesis: Tissue engineering seeks to mimic the properties and functionalities of biological tissue. In the context of bone repair, tissue engineering is becoming an increasingly important science in the active ... -

(Peer reviewed; Journal article, 2021)The prevalent hardening phase forming in an Al-Cu-Mg-Ag alloy after peak-aging at 150 and 190 °C has been investigated using transmission electron microscopy methods. The precipitate atomic structure was determined. It is ... -
Unique photosynthetic electron transport tuning and excitation distribution in heterokont algae
(Journal article; Peer reviewed, 2019)Heterokont algae are significant contributors to marine primary productivity. These algae have a photosynthetic machinery that shares many common features with that of Viridiplantae (green algae and land plants). Here we ... -
Universal absence of Walker breakdown and linear current–velocity relation via spin–orbit torques in coupled and single domain wall motion
