The introduction of holes in a parent compound consisting of copper oxide layers results in high-temperature superconductivity. It is also possible to dope the cuprate parent compound with electrons1–3. The physical properties of these electrondoped materials bear some similarities to but also significant differences from those of their hole-doped counterparts. Here, we use a recently developed...

We investigate the small-particle phonon-polariton response of several microstructures that are made of silicon carbide (SiC). Phonon polaritons can be excited in a wavelength region between 10 and 12 mm. Simple structures such as elliptical cylinders support phonon polaritons at two wavelengths, which depend on the axis ratio of the particle. In particles with a more irregular shape such as re...

The plasmon resonance of metal nanoparticles shifts upon refractive index changes of the surrounding medium through the binding of analytes. The use of this principle allows one to build ultra-small plasmon sensors that can detect analytes (e.g., biomolecules) in volumes down to attoliters. We use simulations based on the boundary element method to determine the sensitivity of gold nanorods of ...

this paper aims at investigating the effects of weld nugget size and expulsion on the mechanical properties of low carbon steel resistance spot welds using tensile-shear test. mechanical performance of spot welds are described in terms of failure mode, peak load and failure energy obtained from the tensile-shear test. the effects of voids and porosity as well as electrode indentation associated...

Near the boundary between ordered and disordered quantum phases, several experiments have demonstrated metallic behaviour that defies Landau Fermi paradigm1–5. In moiré heterostructures, gate-tuneable insulating phases driven by electronic correlations been recently discovered6–23. Here, we use transport measurements to characterize metal–insulator transitions (MITs) in twisted WSe2 near half f...

Abstract Carbonate melts have been proposed to exist in the lower mantle, but their interaction with other mantle melt compositions is poorly understood. To understand miscibility carbonate‐silicate‐metal system, we simulate endmember, binary, and ternary mixtures study how Gibbs free energies of mixing evolve pressure. We find that carbonate‐metal carbonate‐silicate gaps close increasing press...

The cocrystallization of trans-[PtI2(NCN(CH2)5)2] and iodoform (CHI3) yields crystalline adduct trans-[PtI2(NCN(CH2)5)2]∙2CHI3, the structure which was studied via single-crystal X-ray diffractometry (XRD). In XRD apart from rather predictable C–H∙∙∙I hydrogen bonds (HBs) C−I∙∙∙I halogen (XBs) with iodide ligands, we identified C–I∙∙∙Pt metal-involving XBs, where platinum center functions as an...

B. Grizelj, J. Cumin, Mechanical engineering Faculty in Slavonski Brod, Slavonski Brod, Croatia D. Grizelj, Siemens, Zagreb, Croatia. This paper deals with the eff ects of technological parameters used in the V-die bending process, on the obtained product properties and dimensions. By variation of the tool geometry, several cases of steel sheet bending process are observed through the FEM simul...
