Crystal Chemistry at High Pressure [PDF]

open access: yes, 2023
An overview of the behavior of materials at high pressure is presented, starting from the effects on single atoms driving electronic transitions and changes in periodic trends. A range of high-pressure-induced phenomena in the solid state are then discussed building on the atomic changes, including bizarre electronic structures, electrides, compounds ...

Coherent Exciton-Lattice Dynamics in a 2D Metal Organochalcogenolate Semiconductor [PDF]

open access: yesarXiv, 2023
Hybrid organic-inorganic nanomaterials can exhibit transitional behavior that deviates from models developed for all-organic or all-inorganic materials systems. Here, we reveal the complexity of exciton-phonon interactions in a recently discovered 2D layered hybrid organic-inorganic semiconductor, silver phenylselenolate (AgSePh).

Revealing protein structures: crystallization of protein‐ligand complexes – co‐crystallization and crystal soaking

open access: yesFEBS Open Bio, EarlyView.
Co‐crystallization crystallizes a protein with its ligand, resulting in protein–ligand complex crystals. In contrast, soaking introduces a ligand into preformed protein crystals, allowing it to bind. Both methods produce crystals for X‐ray diffraction, which generates diffraction patterns that are analyzed to determine the three‐dimensional structure ...

Charting Lattice Thermal Conductivity of Inorganic Crystals [PDF]

open access: yesarXiv, 2020
Thermal conductivity is a fundamental material property but challenging to predict, with less than 5% out of about $10^5$ synthesized inorganic materials being documented. In this work, we extract the structural chemistry that governs lattice thermal conductivity, by combining graph neural networks and random forest approaches.
