Phase Transformation-Induced Interfacial Debonding of Silica Inclusions in Iron

Andreas Mortensen, David Hernandez Escobar, Julie Nathalie S Gheysen, Alejandra Inés Slagter

We document that in unstressed, undeformed, samples of pure iron containing silica inclusions precipitated by melt deoxidation, the iron matrix and a small fraction of the silica inclusions are locally separated at room temperature by a void. Thermal cycli ...

Direct observation of exchange anisotropy in the helimagnetic insulator Cu2OSeO3

Arnaud Magrez, Priya Ranjan Baral, Jonathan White, Chen Luo

The helical magnetic structures of cubic chiral systems are well explained by the competition among Heisen-berg exchange, Dzyaloshinskii-Moriya interaction, cubic anisotropy, and anisotropic exchange interaction (AEI). Recently, the role of the latter has ...

Structural and Dynamical Properties of Potassium Dodecahydro-monocarba-closo-dodecaborate: KCB11H12

Mirjana Dimitrievska, Wei Zhou

MCB11H12 (M: Li, Na) dodecahydro-monocarba-closo-dodecaborate salt compounds are known to have stellar superionic Li+ and Na+ conductivities in their high-temperature disordered phases, making them potentially appealing electrolytes in all-solid-state batt ...

Iridium(I)/N-Heterocyclic Carbene Hybrid Materials: Surface Stabilization of Low-Valent Iridium Species for High Catalytic Hydrogenation Performance

David Lyndon Emsley, David Benjamin Roger Antoine Gajan

An Ir-I(NHC)-based hybrid material was prepared using a methodology which allowed the precise positioning and isolation of the Ir centers along the pore channels of a silica framework. The full characterization of the material by solid-state NMR spectrosco ...

Solid Solutions of Lead Metaniobate-Stabilization of the Ferroelectric Polymorph and the Effect on the Lattice Parameters, Dielectric, Ferroelectric, and Piezoelectric Properties

Nava Setter, Dragan Damjanovic, Alberto Biancoli, Barbara Maraston Fraygola, Mtabazi Geofrey Sahini

Ferroelectric orthorhombic lead metaniobate (PbNb2O6) is known to be metastable with respect to the thermodynamically stable nonferroelectric rhombohedral polymorph. The high-temperature tetragonal to low temperature rhombohedral phase transition is recons ...

Manipulating nanocrystal doping, structure, and photocatalytic activity with organic ligands

Raffaella Buonsanti, Anna Loiudice

Org. ligands (or surfactants) are key in detg. colloidal nanocrystal structure and, therefore, function. In addn. to their more traditional role as surface passivating agents impacting nanocrystal size and shape, surfactants can also behave as active reage ...

Shock-induced deformation of Shergottites: Shock-pressures and perturbations of magmatic ages on Mars

Philippe Gillet, Pierre Beck

Shergottites and Chassignites practiced major deformation effects whose nature, magnitude and relevance were controversially evaluated and disputatively debated. Our studies of many shocked shergottites present, contrary to numerous previous reports, ample ...

Homologous Critical Behavior in the Molecular Frameworks Zn(CN)(2) and Cd(imidazolate)(2)

Philip Pattison, Vladimir Dmitriev

Using a combination of single-crystal and powder X-ray diffraction measurements, we study temperature- and pressure-driven structural distortions in zinc(II) cyanide (Zn(CN)(2)) and cadmium(II) imidazolate (Cd(im)(2)), two molecular frameworks with the ant ...
