Development of in-situ high-energy X-ray diffraction capability with flash scanning calorimetry.

WEILONG CHEN · Peihao SUN · Jacopo BAGLIONI · Marco DI MICHIEL · y 1 más

This LTP aims at developing a new capability at ESRF combining in-situ high-energy X-ray diffraction with flash differential scanning calorimetry (FDSC). FDSC is an emerging technology that allows for the precise control of sample temperature and the measurement of calorimetric properties at heating/cooling rates of 10...

Investigating the synergistic effect of a doping and an electrolyte on the charge compensation mechanism in P2-type cathodes for SIBs using

Katherine MAZZIO · Hui WANG · Zeynep ERDÖL · Anastasia MOLOKOVA

Mn-based layered oxides, commonly used as cathodes in sodium-ion batteries, have limited lifespans due to unstable electrode-electrolyte interfaces, particularly at voltages above 4.3 V, which cause oxygen loss. This study presents an ultra-low concentration electrolyte (ULCE, ≤0.5M) to address these challenges and enh...

Study of pressure-induced structural phase transitions in the van der Waals multiferroic CuCrP2S6

Steven GEBEL · Alexander MISTONOV · Gaston GARBARINO · SWARNAMAYEE MISHRA

The aim of this proposal is to investigate the the evolution of the atomic lattice in a van der Waals (vdW) multiferroic CuCrP2S6 as a function of pressure and temperature. CuCrP2S6, a type-I multiferroic material, has generated much excitement and is considered as a promising 2D vdW candidate owing to the coexistence...

Time-resolved X-ray absorption spectroscopy to study hematite Fe2O3 and wüstite FeO phase transitions under laser-shock compression

Marion HARMAND · Nicolas SEVELIN-RADIGUET · Mila FITZGERALD · Eglantine BOULARD · y 8 más

Recent studies of Fe-O phase diagrams have revealed important yet not fully understood phenomena, such as new Fe-O stoichiometries, changes in iron spin and oxidation states, which are important for properly modeling both deep planetary interiors and high-velocity meteorite impacts. The important discrepancies observed...

Exploring mesoscopic microstructural ordering in non-stoichiometric La2NiO4+d

Martin MEVEN · Alexander SOLODOV · Tobias Gerhard GROTE · Sreejith POYYERI KUNNATH · y 4 más

La2NiO4+d is a performant oxygen ion conductor already at room temperature. During the electrochemical oxygen uptake/release reaction, a complex twin domain structure, anti-phase boundary domains and mesoscopic domain ordering is observed. The understanding of domain ordering for interface diffusion is mandatory to bet...

Exploring the dynamical signatures of residual stresses in a colloidal glass former

Domenico TRUZZOLILLO (ORCID: 0000-0002-1841-969X) · Vincenzo RUZZI · Luca CIPELLETTI · Alessandro MARTINELLI · y 1 más

Stress-relaxation mechanisms are regularly observed in amorphous systems, ranging from soft colloidal gels to hard metallic glasses. They are often characterized by hyper-diffusive particle displacements and compete with the spontaneous structural relaxations. Despite intense research is ongoing both experimentally and...

Reconstructing a neural circuit in the spinal cord mediating nocifensivebehavior with X-ray nanotomography and electron microscopy

Artem VOROBYEV · Wangchu XIANG · Alexandra JOITA PACUREANU · Wei-Chung LEE (ORCID: 0000-0002-4618-295X)

Animals sense painful stimuli through specialized sensory neurons on the skin and generate nocifensive behaviours to protect themselves from severe injury. Specialized sensory neurons carry nociceptive information to the central nervous systems (CNS) locates in the spinal cord dorsal horn to trigger avoidance behaviour...

Towards Stable Binary Hybrid Perovskite Glasses: a Combined Long- and Short-Range Order Structural Study

ARAD LANG · Emily SHAW · Celia CHEN · Catherine DEJOIE

Hybrid perovskite glasses are a new class of non-crystalline materials formed by melt-quenching crystalline two-dimensional hybrid organic-inorganic perovskites (2D-HOIPs). These materials have the potential for next-generation applications such as optoelectronics, thermoelectrics, and sensing, however, they are unstab...
