Halogen Chains with One-Dimensional Semi-Metallic Electronic Structure and Peierls Physics in Polymorphs of Na4X5 (X = I, Br, Cl) Compounds
Yuqing Yin, Nityasagar Jena, Florian Knoop +16
Since the pioneering works of Peierls, one-dimensional materials have attracted great attention. Still, the synthesis of truly monoatomic chains remains elusive. In this study, we…
Controlled polymorphic competition -- a path to tough and hard ceramics
D. G. Sangiovanni, A. Kjellén, F. Trybel +4
From nanoscale devices including sensors, electronics, or biocompatible coatings to macroscale structural, automotive or aerospace components, fundamental understanding of plastici…
Synthesis of Ultra-Incompressible Carbon Nitrides Featuring Three-Dimensional Frameworks of CN4 Tetrahedra Recoverable at Ambient Conditions
Dominique Laniel, Florian Trybel, Andrey Aslandukov +22
More than thirty years ago, carbon nitrides featuring 3D frameworks of tetrahedral CN4 units were identified as one of the great aspirations of materials science, expected to have…
High-Pressure Synthesis of Seven Lanthanum Hydrides with a Significant Variability of Hydrogen Content

Our recent developments in in-situ nuclear magnetic resonance (NMR) spectroscopy under extreme conditions led to the observation of a wide variety of physical phenomena not accessi…
Proton dynamics in high-pressure ice-VII from density functional theory
Florian Trybel, Michael Cosacchi, Thomas Meier +2
Using a density-functional-theory-based approach, we explore the symmetrization and proton dynamics in ice-VII, for which recent high-pressure NMR experiments indicate significant…
Nuclear Spin Crossover in Dense Molecular Hydrogen
Thomas Meier, Dominique Laniel, Miriam Pena-Alvarez +6
The laws of quantum mechanics are often tested against the behaviour of the lightest element in the periodic table, hydrogen. One of the most striking properties of molecular hydro…
