A new semiconducting perovskite alloy system made possible by gas-source molecular beam epitaxy
Ida Sadeghi, Jack Van Sambeek, Tigran Simonian +5
Optoelectronic technologies are based on families of semiconductor alloys. It is rare that a new semiconductor alloy family is developed to the point where epitaxial growth is poss…
Post-Synthetic Treatment of Nickel-Iron Layered Double Hydroxides for the Optimum Catalysis of the Oxygen Evolution Reaction
Daire Tyndall, Sonia Jaskaniec, Brian Shortall +8
Nickel-iron layered double hydroxide (NiFe LDH) platelets with high morphological regularity and sub-micrometre lateral dimensions were synthesized using a homogeneous precipitatio…
Solvent Engineered Synthesis of Layered SnO Nanoparticles for High-Performance Anodes
Sonia Jaśkaniec, Seán R. Kavanagh, Joao Coelho +5
Batteries are the most abundant form of electrochemical energy storage. Lithium and sodium ion batteries account for a significant portion of the battery market, but high-performan…
Suppression of the Shear Raman Mode in Defective Bilayer MoS2
Pierce Maguire, Clive Downing, Jakub Jadwiszczak +7
We investigate the effects of lattice disorders on the low frequency Raman spectra of bilayer MoS2. The bilayer MoS2 was subjected to defect engineering by irradiation with a 30 ke…
Quantifying the factors limiting rate-performance in battery electrodes
Ruiyuan Tian, Sang-Hoon Park, Paul J. King +4
A significant problem associated with batteries is the rapid reduction of charge-storage capacity with increasing charge/discharge rate. For example, improving this rate-performanc…
Low-temperature synthesis of high quality Ni-Fe layered double hydroxides hexagonal platelets
Sonia Jaskaniec, Christopher Hobbs, Andres Seral-Ascaso +5
This paper describes the wet-chemistry synthesis of highly crystalline hexagonal flakes of Ni-Fe layered double hydroxide (LDH) produced at temperature as low as 100 oC. The flakes…
