Nanosecond timescale plasticity in shock-compressed polycrystalline MgO: evidence for transition in mechanism above 100 GPa
A. Chakraborti, H. Ginestet, F. Bertrand +80
The mechanical properties of ceramics under extreme conditions directly impact applications ranging from shielding spacecrafts, designing plasma facing materials in nuclear fusion…
Direct High-Magnetic-Field Coupling to Stripe Order in a Cuprate Superconductor
Leonardo Martinelli, Izabela Biało, Jens Oppliger +47
Superconductivity in cuprates emerges out of a complex normal state that hosts density waves, pseudogap physics, and strange metal properties. Here, we access this normal state by…
Iron spin crossover in ferropericlase and its effect on lower-mantle thermal conductivity
Alexander F. Goncharov, Irina Chuvashova, Eric Edmund +29
Thermal conductivity of Earths lower mantle controls heat transfer across the core-mantle boundary (CMB) and strongly influences mantle convection. We report direct measurements of…
Structural evolution of iron oxides melts at Earth's outer-core pressures
Céline Crépisson, Mila Fitzgerald, Domenic Peake +32
Oxygen and other light elements comprise up to 5 wt% of the Earth's outer-core, and may significantly influence its physical properties and the operation of the geodynamo. Here we…
Observation of Body-Centered Cubic Iron above 200 Gigapascals
Zuzana Konopkova, Eric Edmund, Orianna B Ball +34
The crystallographic structure of iron under extreme conditions is a key benchmark for cutting-edge experimental and numerical methods. Moreover, it plays a crucial role in underst…
High-Quality Ultra-Fast Total Scattering and Pair Distribution Function Data using an X-ray Free Electron Laser
Adam F. Sapnik, Philip A. Chater, Dean S. Keeble +48
High-quality total scattering data, a key tool for understanding atomic-scale structure in disordered materials, require stable instrumentation and access to high momentum transfer…
Strong geometry dependence of the X-ray Thomson Scattering Spectrum in single crystal silicon
Thomas Gawne, Zhandos A. Moldabekov, Oliver S. Humphries +17
We report on results from an experiment at the European XFEL where we measured the x-ray Thomson scattering (XRTS) spectrum of single crystal silicon with ultrahigh resolution. Com…
Formation of high-aspect-ratio nanocavity in LiF crystal using a femtosecond of x-ray FEL pulse
Sergey S. Makarov, Sergey A. Grigoryev, Vasily V. Zhakhovsky +30
Sub-picosecond optical laser processing of metals is actively utilized for modification of a heated surface layer. But for deeper modification of different materials a laser in the…
X-ray induced grain boundary formation and grain rotation in Bi2Se3
Kento Katagiri, Bernard Kozioziemski, Eric Folsom +24
Optimizing grain boundary characteristics in polycrystalline materials can improve their properties. Many processing methods have been developed for grain boundary manipulation, in…
Thermomechanical response of thickly tamped targets and diamond anvil cells under pulsed hard x-ray irradiation
J. Meza-Galvez, N. Gomez-Perez, A. Marshall +6
In the laboratory study of extreme conditions of temperature and density, the exposure of matter to high intensity radiation sources has been of central importance. Here we interro…
Synthesis of ultra-incompressible sp3-hybridized carbon nitride
Elissaios Stavrou, Sergey Lobanov, Huafeng Dong +4
Search of materials with C-N composition hold a great promise in creating materials which would rival diamond in hardness due to the very strong and relatively low-ionic C-N bond.…
