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
Dominique Laniel, Florian Trybel, Bjoern Winkler +12
The lanthanum-hydrogen system has attracted significant attention following the report of superconductivity in LaH10 at near-ambient temperatures and high pressures. Here, we prese…

Aromatic Hexazine [N6]4- Anion Revealed in the Complex Structure of the High-Pressure Potassium Nitride K9N56
Dominique Laniel, Florian Trybel, Yuqing Yin +13
Recent high-pressure synthesis of pentazolates and subsequent stabilization of the aromatic [N5]- anion at atmospheric pressure had an immense impact on nitrogen chemistry. Here, w…
Absence of proton tunneling during the hydrogen bond symmetrization in -AlOOH
Florian Trybel, Thomas Meier, Biao Wang +1
-AlOOH is of significant crystallochemical interest due to a subtle structural transition near 10 GPa from a to a structure, the nature and origin of hydrogen di…
In-situ High Pressure Nuclear Magnetic Resonance Crystallography
