Black Liquor and Wood Char-Derived Nitrogen-Doped Carbon Materials for Supercapacitors
Tamasauskaite-Tamasiunaite, Loreta; Jablonskienė, Jolita; Šimkūnaitė, Dijana; Volperts, Aleksandrs; Plavniece, Ance; Dobele, Galina; Zhurinsh, Aivars; Jasulaitiene, Vitalija; Niaura, Gediminas; Drabavicius, Audrius; Juel, Mari; Rausseo, Luis César Colmenares; Kruusenberg, Ivar; Kaare, Kätlin; Norkus, Eugenijus (Peer reviewed; Journal article, 2023)Herein, we present a synthesis route for high-efficiency nitrogen-doped carbon materials using kraft pulping residue, black liquor, and wood charcoal as carbon sources. The synthesized nitrogen-doped carbon materials, based ... -
Bubble distribution in fused quartz crucibles studied by micro X-Ray computational tomography. Comparing 2D and 3D analysis
Paulsen, Ove; Rørvik, Stein; Muggerud, Astrid Marie Flattum; Juel, Mari (Peer reviewed; Journal article, 2019)Micro X-Ray computational tomography (µ-CT), has been applied to study the bubble distribution across the wall of fused quartz crucibles used for Czochralski pulling of monocrystalline silicon ingots for solar cells. Two ... -
Cold Sintering as a Cost-Effective Process to Manufacture Porous Zinc Electrodes for Rechargeable Zinc-Air Batteries
Jayasayee, Kaushik; Clark, Simon; King, Cara; Dahl, Paul Inge; Tolchard, Julian R; Juel, Mari (Peer reviewed; Journal article, 2020)Zinc-air batteries (ZABs) offer a sustainable and safe pathway to low-cost energy storage. Recent research shows that thermally-sintered porous Zn electrodes with a three-dimensional network structure can enhance the ... -
The Effect of Pull Speed and Heat Treatment on Thermal Donors in Czhocralski Silicon
Olsen, Espen; Mehl, Torbjørn; Stalheim, Helene Eikaas; Juel, Mari; Søndenå, Rune; Burud, Ingunn (Peer reviewed; Journal article, 2021) -
Minority carrier lifetimes in Cz-Si wafers with intentional V-I transitions
Søndenå, Rune; Ryningen, Birgit; Juel, Mari (Peer reviewed; Journal article, 2017)A p-type Cz-Si crystal has been pulled with varying pulling speed in order to produce wafers containing two distinct regions; A region with silicon self-interstitial defects, and a vacancy dominated region. Band-to-band ... -
Recent developments on manufacturing and characterization of fused quartz crucibles for monocrystalline silicon for photovoltaic applications
Warden, Gabriela Kazimiera; Juel, Mari; Gawel, Bartlomiej Adam; Sabatino, Marisa Di (Peer reviewed; Journal article, 2022)The dominating technology of solar cell production today is based on monocrystalline silicon, produced mostly by the Czochralski process. Recently, the solar cell industry, has started to move towards growing larger and ...
