ALD Zn(O,S) Thin Films’ Interfacial Chemical and Structural Configuration Probed by XAS
Dadlani, Anup; Acharya, Shinjita; Trejo, Orlando; Fritz, Prinz; Torgersen, Jan (Journal article; Peer reviewed, 2016)The ability to precisely control interfaces of atomic layer deposited (ALD) zinc oxysulfide (Zn(O,S)) buffer layers to other layers allows precise tuning of solar cell performance. The O K- and S K-edge X-ray absorption ... -
Comparing physiologically relevant corrosion performances of Mg AZ31 alloy protected by ALD and sputter coated TiO2
Peron, Mirco; Bin Afif, Abdulla Shaikh Abdul Qader; Dadlani, Anup; Berto, Filippo; Torgersen, Jan (Peer reviewed; Journal article, 2020)The utilization of Mg alloys for biomedical applications is so far underexplored due to the accelerated corrosion hampering patient recovery post implantation. Here, we explore the effectiveness of corrosion reduction of ... -
Conductivity control via minimally invasive anti-Frenkel defects in a functional oxide
Evans, Donald; Holstad, Theodor Secanell; Mosberg, Aleksander Buseth; Småbråten, Didrik Rene; Vullum, Per Erik; Dadlani, Anup; Shapovalov, Konstantin; Yan, Zewu; Bourret, Edith; Gao, David Zhe; Akola, Jaakko; Torgersen, Jan; Van Helvoort, Antonius; Selbach, Sverre Magnus; Meier, Dennis (Peer reviewed; Journal article, 2020)Utilizing quantum effects in complex oxides, such as magnetism, multiferroicity and superconductivity, requires atomic-level control of the material’s structure and composition. In contrast, the continuous conductivity ... -

The remarkable catalytic performance for the ... -
Improving stress corrosion cracking behavior of AZ31 alloy with conformal thin titania and zirconia coatings for biomedical applications
Peron, Mirco; Bin Afif, Abdulla Shaikh Abdul Qader; Dadlani, Anup; Berto, Filippo; Torgersen, Jan (Peer reviewed; Journal article, 2020)Magnesium and its alloys have been widely studied as materials for temporary implant devices. However, corrosion-assisted cracking phenomena such as stress corrosion cracking (SCC) continue to prevent their mainstream use. ... -
On the evaluation of ALD TiO2, ZrO2 and HfO2 coatings on corrosion and cytotoxicity performances
Peron, Mirco; Cogo, Susanna; Maria, Bjelland; Bin Afif, Abdulla Shaikh Abdul Qader; Dadlani, Anup; Greggio, Elisa; Berto, Filippo; Torgersen, Jan (Peer reviewed; Journal article, 2021)Magnesium alloys have been widely studied as materials for temporary implants, but their use has been limited by their corrosion rate. Recently, coatings have been proven to provide an effective barrier. Though only little ... -
