High temperature corrosion and corrosion protection of metallic interconnects for SOFC
(Doctoral thesis at NTNU;2015:155, Doctoral thesis, 2015)Reducing solid oxide fuel cells (SOFCs) operation temperature from 900-100 °C to 700-800 °C, has made the substitution of traditional lanthanum chromate (LaCrO3) ceramic interconnect with metallic interconnect possible. ... -
High Temperature Decomposition of Methane on Quartz Pellets
(Master thesis, 2015)This work has shown that pure methane, when exposed to quartz at a temperatures of 900°C and 1000°C, cracks and deposits carbon at a near constant rate. The deposition rates for the individual temperature levels were shown ... -
High temperature interaction between Si–B alloys and Si3N4
(Peer reviewed; Journal article, 2021)Si3N4 is a candidate crucible material for Si–B alloys in high temperature thermal energy storage system. In this regard, the phase formation in the Si–B alloys and the interaction between the alloys and Si3N4 were ... -
High Temperature Interaction of Si-B Alloys with Graphite Crucible in Thermal Energy Storage Systems
(Journal article; Peer reviewed, 2019)Si-B alloys are proposed as a potential phase change material (PCM) in the novel high temperature thermal energy storage systems. For successfully introducing the new PCM, the selection of proper refractory material in the ... -
High temperature X-ray diffraction and thermo-gravimetrical analysis of the cubic perovskite Ba0.5Sr0.5Co0.8Fe0.2O3-δ under different atmospheres
(Journal article; Peer reviewed, 2015)Ba0.5Sr0.5Co0.8Fe0.2O3−δ (BSCF) with the cubic perovskite structure is known to be metastable at low temperature under an oxidizing atmosphere. Here, the thermal and chemical expansion of BSCF were studied by in situ high ... -
High thermoelectric performance and low thermal conductivity in Cu2−yS1/3Se1/3Te1/3 liquid-like materials with nanoscale mosaic structures
(Journal article, 2017)Mosaic-crystal microstructure is one of the optimal strategies for decoupling and balancing thermal and electrical transport properties in thermoelectric materials. Herein, we successfully achieve the desired nanoscale ... -

High-Capacity Amine-Imidazole Solvent Blends for CO2 Capture
(Journal article; Peer reviewed, 2019)The CO2 absorption performance of aqueous solvent blends containing four imidazoles (2-MeIm, 2-Et-4-MeIm, 2,4,5-MeIm and 1,2,4,5-MeIm) and four promoters (MEA, DEA, PZ, and MAPA) were investigated using a small-scale ... -
High-current-density electropolishing (HDEP) of AISI 316L (EN 1.4404) stainless steel
(Journal article; Peer reviewed, 2015)The paper presents new XPS results of surface layers formed after electrochemical polishing of AISI 316L stainless steel at high current density (HDEP) of 1000 A/dm2 (EP1000) versus a standard electropolishing (EP50) process ... -
High-energy astrophysical neutrinos from interactions in the Local Bubble
(Journal article; Peer reviewed, 2020)A signal of high-energy extraterrestrial neutrinos was discovered by the IceCube experiment [1]. Neutrinos are always produced together with gamma-rays, but the gamma-ray flux from extra- galactic sources cascade down to ... -
High-energy Mid-Infrared Cr:ZnS Chirped-pulse oscillator

High-Energy Neutrino and Gamma-Ray Emission from Tidal Disruption Events
(Peer reviewed; Journal article, 2020)Tidal disruption events (TDE) have been considered as cosmic-ray and neutrino sources for a decade. We suggest two classes of new scenarios for high-energy multi-messenger emission from TDEs that do not have to harbor ... -
High-energy neutrino emission from blazars
(Peer reviewed; Journal article, 2022)Active galactic nuclei (AGN) with relativistic jets are the most powerful persistent astrophysical sources of electromagnetic radiation in the Universe. Blazars are the most extreme subclass of AGN with jets directed along ... -
High-energy Neutrinos from Galactic Superbubbles
(Peer reviewed; Journal article, 2018)We study the propagation of cosmic rays (CRs) generated by sources residing inside superbubbles. We show that the enhanced magnetic field in the bubble wall leads to an increase in the interior CR density. Because of the ... -
High-energy X-ray Tomography for 3D Void Characterization in Au–Sn Solid-Liquid Interdiffusion (SLID) Bonds
(Chapter; Peer reviewed, 2019)Au-Sn SLID bonding is a technique originally developed for harsh environment applications. The technology has recently shown promising results for ultrasound transducer fabrication. Characterizing the spatial and size ... -
