(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2004)Pressure effects on the charge-ordering (CO) transition have been investigated for an oxygen-deficient double-perovskite cobalt oxide, BaYCo 2 O 5.0 , through resistivity measurements using a piston-cylinder-type clamp ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Hydrostatic pressure response of LaAuSb2 charge density wave (CDW) system is investigated using electrical transport, x-ray diffraction (XRD), and density-functional theory (DFT). Resistivity data at ambient pressure ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The magnetic properties of iron chalcogenides and pnictides have found much interest as magnetic fluctuations are suggested to drive the formation of Cooper pairs in iron-based superconductors. Here, we have studied the ...
-
(Master thesis / Masteroppgave, 2008)During the past several decades, the amount of SO2 emission in China has steadily increased. The big forest areas in northeast China, located in Hei Longjiang and Ji Lin provinces, are hereby receiving an increasing amount ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)Background: Scientists and regulatory agencies strive to identify chemicals that may cause harmful effects to humans and the environment; however, prioritization is challenging because of the large number of chemicals ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Flexible metal–organic frameworks (MOFs) are known for their vast functional diversities and variable pore architectures. Dynamic motions or perturbations are among the highly desired flexibilities, which are key to guest ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)The main question addressed in this work is how to probe the “effective dead-time” in an NMR instrument, i.e., the time needed to blank the receiver after an rf-pulse excitation to prevent damage to the receiver and to ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The nuclide 266Bh was produced in the 248Cm(23Na,5n)266Bh reaction at beam energies of 125.9, 130.6, and 135.3 MeV. Decay properties of 266Bh were investigated with a rotating wheel apparatus for α and spontaneous fission ...

(Master thesis / Hovedoppgave, 2003)This study has investigated the production of poly(styrene/divinylbenzene) monolithic columns for use in micro LC for protein separations. The 180 µm I.D. x 6 cm poly(styrene/divinylbenzene) monolithic columns were tested ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)The neuropeptide oxytocin (OT) is associated with a plethora of social behaviors, and is a key topic at the intersection of psychology and biology. However, tools for measuring OT are still not fully developed. We describe ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)The properties of the mixed system LiBH4–LiCl–P2S5 are studied with respect to all-solid-state batteries. The studied material undergoes an amorphization upon heating above 60 °C, accompanied with increased Li+ conductivity ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)We have studied a series of Pd/Au alloys as Pt-catchment materials, both in lab-scale experiments and in an industrial ammonia oxidation plant. Our focus has been on how bulk Pt diffusion affects grain reconstruction in ...
