Avoided Crossing Phonons Realizes High‐Performance Single‐Crystalline β‐Zn4Sb3 Thermoelectrics
Published 2025-02-01“…Abstract This study reveals the mechanisms behind the ultralow lattice thermal conductivity κL in β‐Zn4Sb3 single crystals through inelastic neutron scattering (INS). Analyzing phonon behaviors and the interaction between acoustic phonons and rattling modes, the first experimental evidence of avoided crossing in β‐Zn4Sb3 is provided. …”

Molecular mechanisms induced by phase modifiers used in hydrometallurgy: consequences on transfer efficiency and process safety
Published 2022-12-01“…The dominant molecular effect can be identified and quantified by combining surface tension and neutron scattering experiments. In the case of phase modifiers that are hydrotropes, the co-solvent or co-surfactant effect is dominant. …”
