Journal ArticleDOI
The dynamics of methylammonium ions in hybrid organic–inorganic perovskite solar cells
Aurélien M. A. Leguy,Jarvist M. Frost,Andrew P. McMahon,Victoria García Sakai,W Kochelmann,ChunHung Law,Xiaoe Li,Fabrizia Foglia,Aron Walsh,Brian C. O’Regan,Jenny Nelson,João T. Cabral,Piers R. F. Barnes +12 more
TL;DR: Quasielastic neutron scattering measurements show that dipolar CH3NH3+ ions reorientate between the faces, corners or edges of the pseudo-cubic lattice cages in CH3 NH3PbI3 crystals with a room temperature residence time of ∼14 ps, faster than most observed hysteresis.
Journal ArticleDOI
Resilience of Malic Acid Natural Deep Eutectic Solvent Nanostructure to Solidification and Hydration.
Oliver S. Hammond,Daniel T. Bowron,Andrew Jackson,Thomas Arnold,Adrian Sanchez-Fernandez,Nikolaos Tsapatsaris,Victoria García Sakai,Karen J. Edler +7 more
TL;DR: This work unambiguously shows the structure of choline chloride-malic acid (malicine) as a liquid and also in solid and hydrated forms, using neutron total scattering on D/H isotope-substituted samples, and quasi-elastic neutron scattering (QENS).
Journal ArticleDOI
Segmental Dynamics in PMMA-Grafted Nanoparticle Composites
Pinar Akcora,Sanat K. Kumar,Victoria García Sakai,Yu Li,Brian C. Benicewicz,Linda S. Schadler +5 more
TL;DR: In this article, it was shown that at 15 mass % particle loading, composites created using the same grafted nanoparticle, but with two different matrices, yield well dispersed nanoparticles or nanoparticle agglomerates, respectively.
Journal ArticleDOI
Quasielastic neutron scattering in soft matter
TL;DR: In this article, the authors illustrate the potential of quasielastic neutron scattering (QENS) with three kinds of soft materials whose structural units increase in size/complexity: lipids, polymers and biomolecules.
Journal ArticleDOI
Local polymer dynamics in polymer-C60 mixtures.
TL;DR: Incoherent neutron scattering measurements of C60-polymer mixtures reveal that local polymer chain backbone motions in the glassy state are suppressed relative to those of the pure polymer, and the scattering spectrum of the melt suggests that the influence of C 60 on polymer dynamics is limited to the vicinity of the particles at nanosecond time scales.
