Mechanochemically-induced glass formation from two-dimensional hybrid organic-inorganic perovskites

Apr 19, 2024 | pubs.rsc.org | Chumei Ye |J. Thomson |Giulio I. Lampronti |Lauren N. McHugh

Mechanochemically-induced glass formation from two-dimensional hybrid organic–inorganic perovskites† Hybrid organic–inorganic perovskites (HOIPs) occupy a prominent position in the field of materials chemistry due to their attractive optoelectronic properties.
Van Vleck analysis of angularly distorted octahedra using VanVleckCalculator

Dec 22, 2023 | onlinelibrary.wiley.com | J. Thomson

The Van Vleck distortion modes (Van Vleck, 1939) describe all possible displacements of octahedrally coordinated ligands about a core atom. They are particularly useful in the context of the Jahn–Teller (JT) effect (Jahn & Teller, 1937), which in general occurs when a high-symmetry coordination is destabilized with respect to a deviation to lower symmetry as a consequence of electronic degeneracy. The JT effect distorts the crystal structure via the JT distortion.

Bayesian approach to radio frequency interference mitigation

Sep 29, 2023 | link.aps.org | J. Thomson

Interfering signals such as radio frequency interference from ubiquitous satellite constellations are becoming an endemic problem in fields involving physical observations of the electromagnetic spectrum. To address this we propose a novel data cleaning methodology. Contamination is simultaneously flagged and managed at the likelihood level. It is modeled in a Bayesian fashion through a piecewise likelihood that is constrained by a Bernoulli prior distribution.
