Boosted Supercapacitive Energy with High Rate Capability of aCarbon Framework with Hierarchical Pore Structure in an Ionic Liquid
Wang, Xuehang; Zhou, Haitao; Lou, Fengliu; Li, Yahao; Buan, Marthe Emelie Melandsø; Duan, Xuezhi; Walmsley, John Charles; Sheridan, Edel; Chen, De (Journal article; Peer reviewed, 2016)The specific energy of a supercapacitor (SC) with an ionic liquid (IL)-based electrolyte is larger than that using an aqueous electrolyte owing to the wide operating voltage window provided by the IL. However, the wide-scale ... -
Initiation and Propagation of Intergranular Corrosion on AA6005 Aluminium Alloy
Kumari, Shilpa (Doctoral theses at NTNU;2018:391, Doctoral thesis, 2018)The increasing use of 6xxx series aluminium alloys (AlMgSi) in automotive applications is due to its high strength to weight ratio (enabling substantially reduced fuel consumption and CO2 emissions than for heavier materials ... -
Microstructural Characterisation of Features Related to Grain Boundary Corrosion Phenomena in Aluminium Alloys
Lervik, Adrian (Doctoral theses at NTNU;2020:260, Doctoral thesis, 2020)Aluminium (Al) alloys are of great interest as components for the automotive and aerospace industries. These alloys have great mechanical properties and are lighter than their alternatives. Light alloys will effectively ... -
Pd/CeO2 catalysts as powder in a fixed-bed reactor and as coating in a stacked foil microreactor for the methanol synthesis.
Phan, Xuyen Kim; Walmsley, John Charles; Bakhtiary Davijany, Hamidreza; Myrstad, Rune; Pfeifer, Peter; Venvik, Hilde Johnsen; Holmen, Anders (Journal article; Peer reviewed, 2016)Pd/CeO2 as a catalyst for methanol synthesis has been studied in a microreactor consisting of 14 structured foils in a fixed-bed laboratory reactor. Methanol synthesis was carried out at 80 bar and 300 °C with a syngas ... -
Stress Corrosion Cracking in an Extruded Cu-Free Al-Zn-Mg Alloy
Lervik, Adrian; Walmsley, John Charles; Lodgaard, Lars; Marioara, Calin Daniel; Johnsen, Roy; Lunder, Otto; Holmestad, Randi (Peer reviewed; Journal article, 2020)Stress corrosion cracking (SCC) in Cu-free Al-Zn-Mg (7xxx) aluminium alloys limits its use in many applications. In this work, we study in detail the microstructure of a peak and slightly overaged condition in an AA7003 ...
