Impact of composition on the crystal texture and on the dynamics of P(THF-co-ECH) copolymers [PDF]

EPJ Web of Conferences, 2022
We present a combined study by quasielastic neutron scattering (QENS), differential scanning calorimetry (DSC) and wide angle X-ray scattering (WAXS) on poly(tetrahydrofuran-co-epichlorohydrin) copolymers, to see how their composition can be used to tune

How Proton Incorporation Reshapes Lattice Dynamics In BaSnO₃-Type Proton Conductors. [PDF]

Adv Sci (Weinh)
Yttrium‐doped BaSnO3 exhibits isotope‐dependent changes in its low‐energy vibrational density of states upon hydration. Comparison of dry, H2O‐, and D2O‐treated samples re‐veals mass‐dependent phonon renormalization linked to proton dynamics near oxygen va‐cancies, providing experimental insight into hydrogen‐coupled lattice excitations in proton ...

Effect of Halide Variations on Cation Dynamics in MAPbX₃ (X = Cl, Br, and I). [PDF]

Small
This study uncovers the pivotal role of halide composition in dictating MA cation dynamics in MAPbX3 (X = Cl, Br, and I). MAPbCl3 exhibits the earliest and broadest onset of threefold MA rotation with the lowest activation energy, driven by pronounced octahedral distortions and reduced steric hindrance from the smaller Cl⁻ ion.

Quasielastic neutron scattering in biology: Theory and applications [PDF]

Biochimica et Biophysica Acta (BBA) - General Subjects, 2017
Neutrons scatter quasielastically from stochastic, diffusive processes, such as overdamped vibrations, localized diffusion and transitions between energy minima. In biological systems, such as proteins and membranes, these relaxation processes are of considerable physical interest.

Scattering of the halo nucleus 11Be from a lead target at 3.5 times the Coulomb barrier energy

Physics Letters B, 2020
Angular distributions of quasielastic scattering and breakup of the neutron-rich halo nucleus 11Be on a 208Pb target at an incident energy of 140 MeV (about 3.5 times the Coulomb barrier) were measured at HIRFL-RIBLL.

Rational Design of Weakly-Solvating Molecules for Salt-In-Pre-Ionic-Liquid Electrolytes for Li Metal Batteries. [PDF]

Adv Sci (Weinh)
The weakly‐solvating TFMSPyr electrolyte tailors the Li+ solvation structure by suppressing solvent coordination and promoting anion‐dominated solvation. This unique solvation environment induces preferential anion decomposition at electrode interfaces, forming robust inorganic rich S/CEI.

Hydrogen Dynamics in Hydrated Chitosan by Quasi-Elastic Neutron Scattering

Bioengineering, 2022
Chitosan, an environmentally friendly and highly bio-producible material, is a potential proton-conducting electrolyte for use in fuel cells. Thus, to microscopically elucidate proton transport in hydrated chitosan, we employed the quasi-elastic neutron ...

Dynamics of polymer electrolyte with LiTFSI via Quasi-Elastic Neutron Scattering [PDF]

EPJ Web of Conferences, 2023
Most lithium batteries offer a wide range of applications. However, safety issues are still an unresolved issue for several applications. To solve the safety issue of Li-ion batteries, solid polymer electrolyte is a promising candidate to replace ...
