High-pressure synthesis method allows obtaining single-phase perovskite BiFe1−x Sc x O3 ceramics in the entire concentration range. As-prepared compositions with from 0.30 to 0.55 have antipolar orthorhombic Pnma structure but can be irreversible converted into polar rhombohedral R3c or Ima2 phase via annealing at ambient pressure. Microstructure defects and large conductivity of high-pressure-...

Magnetically induced catalysis in solution for the valorization of biomass-derived compounds using FeNi3@Ni nanoparticles.

The anomalous Hall, Nernst, and thermal Hall coefficients of the itinerant ferromagnet Fe3−xGeTe2 display anomalies upon cooling that are consistent with a topological transition could induce deviations respect to Wiedemann–Franz (WF) law. This law has not yet been validated for transport variables, recent experimental studies yielding material-dependent results. Nevertheless, found, within our...

Phase-change materials serve a broad field of applications ranging from non-volatile electronic memory to optical data storage by providing reversible, repeatable, and rapid switching between amorphous crystalline states accompanied large changes in the electrical properties. Here, we demonstrate how ion irradiation can be used tailor disorder initially Ge 2 Sb Te 5 (GST) thin films via intenti...

Substitution effects of Os for Ru in α-RuCl3 are investigated a wide composition range 0 ≤ x 0.67 Ru1−xOsxCl3 by X-ray and electron diffraction, magnetic susceptibility, heat capacity, Raman spectroscopy measurements. Apart from the Kitaev physics with antiferromagnetic interactions increasing x, rich phase diagram is obtained, which includes an long-range order below 12 K 0.15, dome-shaped spi...

The pressure-induced frequency shift of the CH4 and N2 bands is interpreted by quantitatively attributing to attractive repulsive solvation mean-force variation using Lennard–Jones 6-12 potential perturbed hard-sphere fluid model.

The problem of accurate determination of the position, orientation and width of involute spur gear teeth using a single front-lit image is addressed. The information is used to compute global measures of tooth concentricity and pitch variations across a gear wheel. The approach is based on the use of specialised filters which make maximum use of the grey level information available in the image...
