Mauri G, Sykora G, Smith G, Parnell S, Dalgliesh R, Honecker D, et al.
Sci Rep . 2025 Jan; 15(1):3877. PMID: 39890987
Neutron spin-echo techniques exploit Larmor precession of the neutron spin to encode either the scattering angle or energy. These are powerful means to extend the measurable momentum transfer (Q) and...

McKay S, Kuhn S, Shen J, Li F, Doskow J, Visser G, et al.
Rev Sci Instrum . 2024 Nov; 95(11). PMID: 39585178
We present a resonant-mode, transverse-field, radio-frequency (rf) neutron spin flipper design that uses high-temperature superconducting films to ensure sharp transitions between uniform magnetic field regions. Resonant mode allows for low-power,...

Rev Sci Instrum . 2024 Jul; 95(7). PMID: 39016702
We show the implementation of superconducting magnetic Wollaston prisms for spin echo small-angle neutron scattering. Two calibration methods for the spin echo length are presented: one utilizing spin echo modulated...

RSC Adv . 2024 Apr; 14(18):12888-12896. PMID: 38650684
Cellulose membranes were prepared from an EMIMAc ionic liquid solution by nonsolvent-induced phase separation (NIPS) in coagulation baths of water-acetone mixtures, ethanol-water mixtures and water at different temperatures. High water...

Chen S, Kokalari I, Parnell S, Smith G, Zeng B, Way T, et al.
Langmuir . 2023 Jul; 39(29):10033-10046. PMID: 37433143
Waterborne polyurethane (WPU) has attracted significant interest as a promising alternative to solvent-based polyurethane (SPU) due to its positive impact on safety and sustainability. However, significant limitations of WPU, such...

van der Maas E, Famprikis T, Pieters S, Dijkstra J, Li Z, Parnell S, et al.
J Mater Chem A Mater . 2023 Mar; 11(9):4559-4571. PMID: 36866387
Chloride-based solid electrolytes are considered interesting candidates for catholytes in all-solid-state batteries due to their high electrochemical stability, which allows the use of high-voltage cathodes without protective coatings. Aliovalent Zr(iv)...
