Biomass based activated carbon electrodes for capacitative deionization in the context of nitrate and phosphate removal
Krishnamurthy, Shreenath; Jayasayee, Kaushik; Enebakk Eide, Tom-Andre; Stensrød, Ruth Elisabeth (Peer reviewed; Journal article, 2023)Capacitative deionization (CDI) technique is widely pursued for the removal and recovery of ionic contaminants from wastewater, as it does not leave secondary waste and can operate at low voltages < 1.2V vs. reversible ... -
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 ... -
Evaluation of Electrosorption Process for Phosphate and Nitrate Removal from Wastewater
Krishnamurthy, Shreenath; Jayasayee, Kaushik; Enebakk Eide, Tom-Andre; McCay, Katie; Tschentscher, Roman; Stensrød, Ruth Elisabeth; Sunding, Martin Fleissner (Peer reviewed; Journal article, 2022)The present work is dedicated to the preparation and characterization of carbon-based electrodes for the removal of phosphates and nitrate ions from wastewater by CDI method. Carbons obtained from the pyrolysis were used ... -
Hematite microdisks as an alternative anode material for lithium-ion batteries
Balasingam, Suresh Kannan; Kundu, Manab; Balamuralitharan, Balakrishnan; Kim, Hee-Je; Svensson, Ann Mari; Jayasayee, Kaushik (Journal article; Peer reviewed, 2019)In this work, hematite microdisks (500 nm to 1 μm in diameter, ∼200 nm in thickness) have been synthesized by a facile hydrothermal method which exhibited good cycling stability at a current density of 200 mA g−1 and ... -
Non-Nucleophilic Electrolyte Based on Ionic Liquid and Magnesium Bis(diisopropyl)amide for Rechargeable Magnesium-Ion Batteries
Kallidanthiyil Chellappan, Lethesh; Kvello, Jannicke Hatlø; Tolchard, Julian R; Dahl, Paul Inge; Hanetho, Sidsel Meli; Berthelot, Romain; Fiksdahl, Anne; Jayasayee, Kaushik (Peer reviewed; Journal article, 2020)A non-nucleophilic electrolyte for rechargeable Mg-ion batteries is developed by the reaction of magnesium bis(diisopropyl)amide and 1-ethyl-3-methylimidazolium tetrachloroaluminate ionic liquid in tetrahydrofuran solvent. ... -
Robust nanocomposites of a-Fe2O3 and N-doped graphene oxide: Interfacial bonding and chemisorption of H2O
Polfus, Jonathan M.; Jayasayee, Kaushik (Peer reviewed; Journal article, 2019)Nanocomposites of α-Fe2O3 (hematite) and (N-doped) graphene oxide (GO) were investigated using first-principles calculations with focus on structure, chemical bonding, electronic structure and H2O adsorption. The nanocomposites ...
