• Al-Cu intermetallic phase growth in hybrid metal extrusion & bonding welds exposed to isothermal annealing or direct current cycling 

  Sørhaug, Jørgen Andre; Elkjaer, Aksel; Thronsen, Elisabeth; Bergh, Tina; Grong, Øystein; Vullum, Per Erik; Holmestad, Randi (Peer reviewed; Journal article, 2024)

  Joining of aluminium (Al) to copper (Cu) is of great interest to power generation, transportation and electronic industry. However, dissimilar metal joining often promotes intermetallic phase formation at the joined ...

• Embrittlement, degradation, and loss prevention of hydrogen pipelines 

  Giannini, Leonardo; Razavi, Nima; Alvaro, Antonio; Paltrinieri, Nicola (Peer reviewed; Journal article, 2024)

  The detrimental effects induced by hydrogen on different materials—including steels—are a well-known and studied phenomenon. In the last century, several research papers focusing on hydrogen damages were published, including ...

• Effect of model methanogens on the electrochemical activity, stability, and microbial community structure of Geobacter spp. dominated biofilm anodes 

  Dzofou Ngoumelah, Daniel; Heggeset, Tonje Marita Bjerkan; Haugen, Tone; Sulheim, Snorre; Wentzel, Alexander; Harnisch, Falk; Kretzschmar, Jörg (Peer reviewed; Journal article, 2024)

  Combining anaerobic digestion (AD) and microbial electrochemical technologies (MET) in AD-MET holds great potential. Methanogens have been identified as one cause of decreased electrochemical activity and deterioration of ...

• Combined silicon refining for boron removal and Si-Kerf recycling using K2O-CaO-SiO2 slags 

  Zhu, Mengyi; Wu, Guixuan; Tang, Kai; Müller, Michael; Safarian, Jafar (Peer reviewed; Journal article, 2024)

  It is crucial for the photovoltaic (PV) industry to establish a circular materials flow for more sustainable solar silicon production. In the present work, a series of K2O-SiO2 and K2O-CaO-SiO2 slags were examined for the ...

• Assessing fracture toughness of vintage and modern X65 pipeline steels under in situ electrochemical hydrogen charging using advanced testing methodology 

  Myhre, Aleksander Omholt; Wan, Di; Sendrowicz, Aleksander; Nyhus, Bård; Matsunaga, H.; Olden, Vigdis; Alvaro, Antonio; Vinogradov, Alexei (Peer reviewed; Journal article, 2024)

  The susceptibility of pipeline steels to hydrogen embrittlement, which can significantly impair mechanical performance, especially fracture toughness, is a critical issue in infrastructure integrity. This study evaluates ...
