All-oxide thermoelectric module with in situ formed non-rectifying complex p-p-n junction and transverse thermoelectric effect
(Journal article; Peer reviewed, 2018)All-oxide thermoelectric modules for energy harvesting are attractive due to high temperature stability, low cost, and the potential to use non-scarce and non-toxic elements. Thermoelectric modules are mostly fabricated ... -
Electronic Structure and Surface Chemistry of Hexagonal Boron Nitride on HOPG and Nickel Substrates
(Peer reviewed; Journal article, 2023)The effect of point defects and interactions with the substrate are shown by density functional theory calculations to be of significant importance for the structure and functional properties of hexagonal boron nitride ... -
Influence of Atmosphere and Temperature on Polycyclic Aromatic Hydrocarbon Emissions from Green Anode Paste Baking
(Peer reviewed; Journal article, 2023)Coal tar pitch, a well-known source of polycyclic aromatic hydrocarbons (PAHs), is used as a binder of petroleum coke in prebaked anodes used for electrolysis of aluminum. Anodes are baked up to 1100 °C over a 20-day period, ... -
Limitations of Ultrathin Al2O3 Coatings on LNMO Cathodes
(Peer reviewed; Journal article, 2021)This study demonstrates the application of Al2O3 coatings for the high-voltage cathode material LiNi0.5–xMn1.5+xO4−δ (LNMO) by atomic layer deposition. The ultrathin and uniform coatings (0.6–1.7 nm) were deposited on LNMO ... -
Molybdate and phosphate cross-linked chitosan films for corrosion protection of hot-dip galvanised steel
(Peer reviewed; Journal article, 2023)Environmentally friendly and sustainable methods to protect hot-dip galvanized (HDG) steel from corrosion are extensively studied. Films of the biopolymer polyelectrolyte chitosan were ionically cross-linked in this work ... -
Removing fluoride-terminations from multilayered V2CTx MXene by gas hydrolyzation
(Peer reviewed; Journal article, 2022)Two-dimensional MXenes have shown great promise for many different applications, but in order to fully utilize their potential, control of their termination groups is essential. Here we demonstrate hydrolyzation with a ... -
Structures and Role of the Intermediate Phases on the Crystallization of BaTiO3 from an Aqueous Synthesis Route
(Peer reviewed; Journal article, 2021)Carbonate formation is a prevailing challenge in synthesis of BaTiO3, especially through wet chemical synthesis routes. In this work, we report the phase evolution during thermal annealing of an aqueous BaTiO3 precursor ... -
Synthetic Efforts to Investigate the Effect of Planarizing the Triarylamine Geometry in Dyes for Dye-Sensitized Solar Cells
(Peer reviewed; Journal article, 2022)The geometry of a dye for dye-sensitized solar cells (DSSCs) has a major impact on its optical and electronic properties. The dye structure also dictates the packing properties and how well the dye insulates the metal–oxide ... -
Time-enhanced performance of oxide thermoelectric modules based on a hybrid p-n junction
(Peer reviewed; Journal article, 2021)The present challenge with all-oxide thermoelectric modules is their poor durability at high temperatures caused by the instability of the metal-oxide interfaces at the hot side. This work explains a new module concept ...
