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 Na3(N2)4, Ca3(N2)4, Sr3(N2)4, and Ba(N2)3 Featuring Nitrogen Dimers with Non-Integer Charges and Anion-Driven Metallicity
Dominique Laniel, Bjoern Winkler, Timofey Fedotenko +12
Charged nitrogen dimers are ubiquitous in high-pressure binary metal-nitrogen systems. They are known to possess integer formal charges x varying from one through four. Here, we pr…
X-ray Diffraction and Equation of State of the C-S-H Room-Temperature Superconductor
Anmol Lamichhane, Ravhi Kumar, Muhtar Ahart +10
X-ray diffraction indicates that the structure of the recently discovered room temperature carbonaceous sulfur hydride (C-S-H) superconductor is derived from previously established…
Structure and composition of C-S-H compounds up to 143 GPa
Elena Bykova, Maxim Bykov, Stella Chariton +7
We synthesized two C-S-H compounds from a mixture of carbon and sulfur in hydrogen and from sulfur in mixed methane-hydrogen fluids at 4 GPa. X-ray synchrotron single-crystal diffr…
Stabilization of hexazine rings in potassium polynitride at high pressure
Yu Wang, Maxim Bykov, Elena Bykova +6
Polynitrogen molecules represent the ultimate high energy-density materials as they have a huge potential chemical energy originating from their high enthalpy. However, synthesis a…
High-pressure polymeric nitrogen allotrope with the black phosphorus structure
Dominique Laniel, Bjoern Winkler, Timofey Fedotenko +6
Studies of polynitrogen phases are of great interest for fundamental science and for the design of novel high energy density materials. Laser heating of pure nitrogen at 140 GPa in…
