Electrochemical enhancement and inhibition of calcium carbonate deposition
(Peer reviewed; Journal article, 2020)Calcium carbonate is by far the most widespread scaling material. Its deposition in pipes and flowlines has been a long-standing problem for many industries. Hence, a lot of research is devoted to scale inhibition. One of ... -
On the model-dependence of the relation between minimum-bias and inelastic proton-proton cross sections
(Peer reviewed; Journal article, 2011)The model-dependence of the relation between the inelastic and various minimum-bias proton–proton cross sections is analyzed, paying a special attention to the sensitivity of minimum-bias triggers to diffractive collisions. ... -
Influence of Polymer Charge on the Localization and Dark- and Photo-Induced Toxicity of a Potential Type I Photosensitizer in Cancer Cell Models
(Peer reviewed; Journal article, 2020)A current trend within photo-dynamic therapy (PDT) is the development of molecular systems targeting hypoxic tumors. Thus, type I PDT sensitizers could here overcome traditional type II molecular systems that rely on the ... -

(Peer reviewed; Journal article, 2019)The paper presents a fundamental study of the properties and functions of well‐defined Ni−Ag surface alloys in methane decomposition and steam reforming, aiming at providing a better understanding of the principle for ... -
Non-activated adsorption of methane on nickel surfaces induced by reduced work function
(Peer reviewed; Journal article, 2020)Adsorption of methane has been studied in ultrahigh vacuum environments on single crystalline as well as on Ni nano-particles on mica substrates. Experimental techniques have been X-ray and ultraviolet photoelectron ... -
Morpholino target molecular properties affect the swelling process of oligomorpholino-functionalized responsive hydrogels
(Peer reviewed; Journal article, 2020)Responsive hydrogels featuring DNA as a functional unit are attracting increasing interest due to combination of versatility and numerous applications. The possibility to use nucleic acid analogues opens for further ... -
Impact of Silanization Parameters and Antibody Immobilization Strategy on Binding Capacity of Photonic Ring Resonators
(Peer reviewed; Journal article, 2020)Ring resonator-based biosensors have found widespread application as the transducing principle in “lab-on-a-chip” platforms due to their sensitivity, small size and support for multiplexed sensing. Their sensitivity is, ... -
Dense carbon-nanotube coating scaffolds stimulate osteogenic differentiation of mesenchymal stem cells
(Peer reviewed; Journal article, 2020)Carbon nanotubes (CNTs) have desirable mechanical properties for use as biomaterials in orthopedic and dental area such as bone- and tooth- substitutes. Here, we demonstrate that a glass surface densely coated with ... -
Swelling Dynamics of a DNA-Polymer Hybrid Hydrogel Prepared Using Polyethylene Glycol as a Porogen
(Peer reviewed; Journal article, 2015)DNA-polyacrylamide hybrid hydrogels designed with covalent and double-stranded (dsDNA) crosslinks respond to specific single-stranded DNA (ssDNA) probes by adapting new equilibrium swelling volume. The ssDNA probes need ... -
Ultrasound Beamforming based on Deep Learning
(Master thesis, 2020)Stråleforming blir brukt av enheter som tar opp eller sender signaler med flere enn én kanaler for å gi sterkere signalstyrke i en gitt retning. Innen ultralyd kan bedre algoritmer for stråleforming gi økt bildekvalitet, ... -
