(Master thesis / Hovedoppgave, 2004)Målet for syntesene i denne oppgaven var å forsøke å lage porøse materialer med en topologi tilsvarende OSO-topologien, men hvor beryllium blir erstattet med sink. Det ble gjort hydrotermale synteser i tre forskjellige ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)For the successful implementation of catalysts in industrial processes, three overall goals are optimized: activity, selectivity, and stability. This review will address the role of chemical descriptors in aiding and guiding ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)In the past few decades, advances in colloidal nanoparticle synthesis have created new possibilities for the preparation of supported model catalysts. However, effective removal of surfactants is a prerequisite to evaluate ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)In this work, we study the mechanism of the implantation process of two-dimensional molybdenum disulfide. We proposed the oxidation scheme and investigated the changes in the geometry of the MoS2 layer, as well as HOMO and ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)When learning chemistry, students must learn to extract chemical information from mathematical expressions. However, chemistry students’ exposure to mathematics often comes primarily from pure mathematics courses, which ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The valorization of CO2 to produce high-value chemicals, such as methanol and hydrocarbons, represents key technology in the future net-zero society. Herein, we report further investigation of a PdZn/ZrO2 + SAPO-34 catalyst ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)This rosarium article relates the adventure started 50 years ago of a computational chemist who was interested in molecules; what are they, what are their shape and how do they react. The story describes results, still ...

(Master thesis / Masteroppgave, 2009)ABSTRACT In this study, 6-chloropurines with varied substituents in the 2 and 9 or 7 positions were functionalized in the 8-position. This was done via lithiation and subsequent bromination to form 8-brominated purines. It ...
-
(Master thesis / Masteroppgave, 2011)The present thesis is focused on the methodology of lithiation-halogenation of 6-chloro-9-substituted purines and 9-substituted adenines via 8-purinyl anions. As an extension of this work, lithiation-halogenation of ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The heaviest currently known nuclei, which have up to 118 protons, have been produced in 48Ca induced reactions with actinide targets. Among them, the element tennessine (Ts), which has 117 protons, has been synthesized ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract. Secondary organic aerosol (SOA) is a dominant contributor of fine particulate matter in the atmosphere, but the complexity of SOA formation chemistry hinders the accurate representation of SOA in models. ...
-
(Master thesis / Masteroppgave, 2007)Sammensetning og egenskaper til DNOM i vann varierer med nedbørfeltets karakter. Vegetasjon, geologi, topografi og klima, særlig temperatur og nedbør virker inn på de fysiokjemiske egenskapene til DNOM. Hensikten med denne ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)A galvanic deposition method for the in-situ formation of Pt nanoparticles (NPs) on top and inner surfaces of high-aspect-ratio black TiO2-nanotube electrodes (bTNTs) for true utilization of their total surface area has ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)There is a growing need to control and tune nanoparticles (NPs) to increase their stability and effectiveness, especially for photo- and electrochemical energy conversion applications. Exsolved particles are well anchored ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The reactivity of HMg+, HMgCl, and HMgCl2− in hydride transfer reactions with CO2 and CH2O were studied by means of the reverse reactions—decarboxylation of HCO2MgCln+/0/− and deformylation of CH3OMgCln+/0/− (n = 0–2)—by ...
