The Effects of Power Ultrasound (24 kHz) on the Electrochemical Reduction of CO2 on Polycrystalline Copper Electrodes
Islam, Md Hujjatul; Mehradi, Hamed; Coridan, Robert H.; Burheim, Odne Stokke; Hihn, Jean-Yves; Pollet, Bruno (Peer reviewed; Journal article, 2021)The electrochemical CO2 reduction reaction (CO2RR) on polycrystalline copper (Cu) electrode was performed in a CO2-saturated 0.10 M Na2CO3 aqueous solution at 278 K in the absence and presence of low-frequency high-power ... -
Evaluating natural degassing in a river to create a baseline for comparison to technical degassing methods.
Kuhn, Wolf Ludwig; Solemslie, Bjørn Winther; Hihn, Jean-Yves; Dahlhaug, Ole Gunnar (Peer reviewed; Journal article, 2023)In Norway, a recent project used a risk matrix to identify about 200 hydropower plants ( 11 % of the total number) of being in high risk of producing air-supersaturated water. The combined installed capacity of these ... -
Evaluation of ultrasonic degasification as a tool to mitigate total dissolved gas supersaturation downstream hydropower plants
Kuhn, Wolf Ludwig (Doctoral theses at NTNU;2023:445, Doctoral thesis, 2023)This Doctoral Thesis evaluates ultrasonic degasification as a potential tool for mitigating total dissolved gas (TDG) supersaturation in the river downstream a hydropower plant. The volumetric liquid-gas mass transfer ... -
(Invited) Novel Fuel Production Based on Sonochemistry and Sonoelectrochemistry
Islam, Md. H.; Lamb, Jacob J.; Lien, Kristian M.; Burheim, Odne Stokke; Hihn, Jean-Yves; Pollet, Bruno (Journal article; Peer reviewed, 2019)Sonochemistry has been used in many applications where it is employed to improve both catalytic and synthetic processes; whereas, sonoelectrochemistry has been used in various studies including organic syntheses, environmental ... -
Sonochemical and sonoelectrochemical conversion of CO2 into hydrocarbons
Islam, Md Hujjatul (Doctoral theses at NTNU;2021:158, Doctoral thesis, 2021)Carbon dioxide (CO2) is one of the major greenhouse gas (GHG) contributors to global climate change. Combustion of fossil fuels accounts for approximately 80-90 % of the global CO2 emission, which over the last decade, has ... -
Sonochemical conversion of CO<inf>2</inf> into hydrocarbons: The Sabatier reaction at ambient conditions
Islam, Md Hujjatul; Burheim, Odne Stokke; Hihn, Jean-Yves; Pollet, Bruno (Journal article; Peer reviewed, 2021) -
Sonoelectrochemistry: Both a tool for investigating mechanisms and for accelerating processes
Hihn, Jean-Yves; Doche, Marie-Laure; Hallez, Loïc; Et Taouil, Abdeslam; Pollet, Bruno (Journal article; Peer reviewed, 2018)Surface irradiation by power ultrasound has proven to offer beneficial effects not only for surface cleaning, but also for the modification of functional properties of metallic or organic coatings. However, the process ... -
The use of non-cavitating coupling fluids for intensifying sonoelectrochemical processes
Islam, Md Hujjatul; Naidji, Bouzid; Hallez, Loic; Et Taouil, Abdeslam; Hihn, Jean-Yves; Burheim, Odne Stokke; Pollet, Bruno (Peer reviewed; Journal article, 2020)For the first time, we have investigated the beneficial effects of non-cavitating coupling fluids and their moderate overpressures in enhancing mass-transfer and acoustic energy transfer in a double cell micro-sonoreactor. ...
