(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Catalytic methane steam reforming was conducted at low temperature using a Pd catalyst supported on Ce1−xMxO2 (x = 0 or 0.1, M = Ca, Ba, La, Y or Al) oxides with or without an electric field (EF). The effects of the catalyst ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Nh2, Fl2, Mc2, Lv2, Ts2, and Og2 are used to investigate the effects of relativity on the 7th row in the periodic table. The present theoretical molecular data suggest the domination of p-orbitals for chemical bonding with ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2014)The biogeochemical cycling of mercury (Hg) in the marine environment is an issue of global concern, as consumption of marine fish is a major route of human exposure to the toxic specie methylmercury (MeHg). The most widely ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2014)Despite an increasing focus on low level methods for determination of mercury species in water over the last decades, few studies have paid attention to direct effects of different sample preparation methods (i.e. preservation ...
-
(Master thesis / Masteroppgave, 2014)In this study, association properties of aqueous solutions of anionic thermo-responsive hydrophobically end-capped amphiphilic triblock terpolymer n-octadecyl-poly(ethylene glycol)-poly(N-isopropyl acrylamide)-block-poly ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The spin ice materials Ho2Ti2O7 and Dy2Ti2O7 are experimental and theoretical exemplars of highly frustrated magnetic materials. However, the effects of applied uniaxial pressure are not well studied, and here we report ...
-
(Master thesis / Masteroppgave, 2013)Tidligere studier har vist at Y-dopet BaZrO3 er en lovende protonleder, ettersom den kombinerer høy bulkledningsevne med god kjemisk stabilitet. Problemet med dette materialet er svært resistive korngrenser som resulterer ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)A cationic nickel complex of the bis(8-quinolyl)(3,5-di-tert-butylphenoxy)phosphine (NPN) ligand, [(NPN)NiCl]+, is a precursor to efficient catalysts for the hydrosilation of alkenes with a variety of hydrosilanes under ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)We show how an existing concurrent multi-scale method named hybrid particle field-molecular dynamics (hPF-MD) can be adapted to enable the simulation of structure and/or structural dynamics in compressible systems. ...
