Bullet pressure-cell design for neutron scattering experiments with horizontal magnetic fields and dilution temperatures

Henrik Moodysson Rønnow, Richard Gaal, Ellen Fogh, Gaétan Charles Antoine Giriat, Luc Testa, Jana Pásztorová

The simultaneous application of high magnetic fields and high pressures for controlling magnetic ground states is important for testing our understanding of many-body quantum theory. However, the implementation for neutron scattering experiments presents a ...

Levitation Force Enhancement in Single-Sided Linear Induction Motors

Mario Paolone, André Hodder, Simone Rametti

Traditional magnetic levitation trains (maglev) generally use two or three separate systems to perform propulsion, levitation, and guidance (PLG) functionalities. Linear electromagnetic motors (LEMs) may be used for propulsion, electromagnetic suspension ( ...

Well-Defined Co2 Dual-Atom Catalyst Breaks Scaling Relations of Oxygen Reduction Reaction

Xile Hu, Yiwei Zheng

The 4-electron oxygen reduction reaction (ORR) under alkaline conditions is central to the development of non-noble metal-based hydrogen fuel cell technologies. However, the kinetics of ORR are constrained by scaling relations, where the adsorption free en ...

Real-and reciprocal space characterization of the three-dimensional charge density wave in quasi-one-dimensional CuTe

Arnaud Magrez, Jan Hugo Dil, Michele Puppin, Eduardo Bonini Guedes, Fei Guo, Lukas Jürgen Hellbrück

Low-dimensional materials are susceptible to electronic instabilities such as charge density waves (CDWs), originating from a divergence in the Lindhard electron response function, combined with a finite electron-phonon coupling strength. In this paper, we ...

Structural phase transition in NH₄F under extreme pressure conditions

Richard Gaal

Ammonium fluoride (NH₄F) exhibits a variety of crystalline phases depending on temperature and pressure. By employing Raman spectroscopy and synchrotron X-ray diffraction beyond megabar pressures (up to 140 GPa), we have here observed a novel dense solid p ...

Superconductivity in nickelate and cuprate superconductors with strong bilayer coupling

Bruce Normand

The discovery of superconductivity at 80 K under high pressure in La3Ni2O7 3 Ni 2 O 7 presents the groundbreaking confirmation that high-Tc T c superconductivity is a property of strongly correlated materials beyond cuprates. We use density functional theo ...

Frequency and time domains interactions in nanophotonics

Andrei Kiselev

In this thesis, we discuss the problems of scattering and optical manipulation related to nanosystems of different complexities. The multipolar decomposition method is used to represent scattering processes in nanosystems as a series of elementary excitati ...

Observation of a Plastic Crystal in Water-Ammonia Mixtures under High Pressure and Temperature

Livia Eleonora Bove Kado

Solid mixtures of ammonia and water, the so-called ammonia hydrates, are thought to be major components of solar and extra-solar icy planets. We present here a thorough characterization of the recently reported high pressure (P)-temperature (T) phase VII o ...

Deformation mechanisms of primary ?? precipitates in nickel-based superalloy

Roland Logé

Coarse gamma ' precipitates with ordered structure (i.e. primary gamma ' precipitates) residing on grain boundaries in nickelbased superalloys are generally considered to be non-deformable, they are thus being tailored to restrict grain growth during hot d ...

Synthesis and crystal structure of Fe[SeO4]OH and prediction of polytypes in the extended R[MO4]Z family

Arnaud Magrez, Alla Arakcheeva, Wen Hua Bi, Benoît Guilhem Michel Binh Truc

Single crystals of Fe[SeO4]OH have been synthesized by hydrothermal treatment. The Fe[SeO4]OH structure was investigated using the superspace approach. It is shown that the structure belongs to a family of compounds including kieserite-like and pauflerite- ...
