Does power ultrasound (26 kHz) affect the hydrogen evolution reaction(HER) on Pt polycrystalline electrode in a mild acidic electrolyte?
Pollet, Bruno; Foroughi, Faranak; Faid, Alaa; Emberson, David; Islam, Md Hujjatul (Peer reviewed; Journal article, 2020)In this study, we investigated the effects of power ultrasound (26 kHz, up to ∼75 W/cm2, up to 100% acoustic amplitude, ultrasonic horn) on the hydrogen evolution reaction (HER) on a platinum (Pt) polycrystalline disc ... -
Effect of power ultrasound and Fenton reagents on the biomethane potential from steam-exploded birchwood
Lamb, Jacob Joseph; Islam, Md Hujjatul; Hjelme, Dag Roar; Pollet, Bruno; Lien, Kristian Myklebust (Journal article; Peer reviewed, 2019)The global demand for non-fossil energy sources is increasing rapidly. As a result, biogas presents a suitable alternative; however, first generation biofuels (e.g., sugar cane) potentially impact food crops globally. ... -
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 ... -
Flame Retardant Effect of Nano Fillers on Polydimethylsiloxane Composites
Jagdale, Pravin; Salimpour, Samera; Islam, Md Hujjatul; Cuttica, Fabio; Robles Hernandez, Francisco C.; Tagliaferro, Alberto; Frache, Alberto (Journal article; Peer reviewed, 2018)Polydimethylsiloxane has exceptional fire retardancy characteristics, which make it a popular polymer in flame retardancy applications. Flame retardancy of polydimethylsiloxane with different nano fillers was studied. ... -
How do dissolved gases affect the sonochemical process of hydrogen production? An overview of thermodynamic and mechanistic effects – On the “hot spot theory”
Kerboua, Kaouther; Merouani, Slimane; Hamdaoui, Oualid; Alghyamah, Abdulaziz; Islam, Md Hujjatul; Hansen, Henrik Erring; Pollet, Bruno (Peer reviewed; Journal article, 2020)Although most of researchers agree on the elementary reactions behind the sonolytic formation of molecular hydrogen (H2) from water, namely the radical attack of H2O and H2O2 and the free radicals recombination, several ... -
How to Avoid Total Dissolved Gas Supersaturation in Water from Hydropower Plants by Employing Ultrasound
Rognerud, Maren Elise; Solemslie, Bjørn Winther; Islam, Md Hujjatul; Pollet, Bruno (Peer reviewed; Journal article, 2020)In Norway, more than 10 hydropower plants are known to have caused biologically relevant levels of total dissolved gas supersaturation in the rivers downstream power plants. This phenomenon is causing fish kills due to gas ... -

Islam, Md Hujjatul; Paul, Maichael T.Y.; Burheim, Odne Stokke; Pollet, Bruno (Peer reviewed; Journal article, 2019)In recent years, the synthesis and use of nanoparticles have been of special interest among the scientific communities due to their unique properties and applications in various advanced technologies. The production of ... -
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 and Sonoelectrochemical Production of Hydrogen - A Review
Islam, Md Hujjatul; Burheim, Odne Stokke; Pollet, Bruno (Journal article; Peer reviewed, 2018)Reserves of fossil fuels such as coal, oil and natural gas on earth are finite. The continuous use and burning of these fossil fuel resources in the industrial, domestic and transport sectors has resulted in the extremely ... -
