Finite element modeling of the WC-10 wt.% Co thermal stresses: Build-up and phase specific strain response during cyclic loading

Daniele Mari, Emiliano Campitelli

Several finite element models of the morphology of WC-10 wt.% Co were employed to reproduce the build-up of thermal residual stresses as well as the phase specific strain during loading-unloading in compression. The different models differ only in their ge ...

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 ...

Biomimetic Pieris rapae’s Nanostructure and Its Use as a Simple Sucrose Sensor

Philippe Renaud, David Vincent Bonzon, Rodrigo Martinez Duarte

iomimetics often provides efficient ways to create a product incorporating novel properties. Here we present the replication of the Pieris rapae butterfly optical structure. This butterfly has white wings with black spots. The white coloration is produced ...

Performance of ceramic anvils for high pressure neutron scattering

Livia Eleonora Bove Kado

Three kinds of ceramics, zirconia-toughened alumina (ZTA), alumina-toughened zirconia (ATZ) and yttria-stabilized zirconia (YSZ), were tested as anvil materials, mainly for the purpose of neutron scattering study under high pressure. ZTA with non-toroidal ...

Spin-resolved optical conductivity of two-dimensional group-VIB transition-metal dichalcogenides

Nicola Marzari, Marco Gibertini

We present an ab initio study of the spin-resolved optical conductivity of two-dimensional (2D) group-VIB transition-metal dichalcogenides (TMDs). We carry out fully relativistic density-functional-theory calculations combined with maximally localized Wann ...

Easily-prepared dinickel phosphide (Ni2P) nanoparticles as an efficient and robust electrocatalyst for hydrogen evolution

Xile Hu, Michaël Bensimon, Heron Vrubel, Ligang Feng

Polydispersed dinickel phosphide (Ni2P) nanoparticles were synthesized by a simple and scalable solid-state reaction. These nanoparticles are an excellent and robust catalyst for the electrochemical hydrogen evolution reaction, operating in both acidic and ...

Gold-Free Ternary III-V Antimonide Nanowire Arrays on Silicon: Twin-Free down to the First Bilayer

Sonia Conesa Boj

With the continued maturation of III-V nanowire research, expectations of material quality should be concomitantly raised. Ideally, III-V nanowires integrated on silicon should be entirely free of extended planar defects such as twins, stacking faults, or ...

Origin of Anomalous Slip in Tungsten

Helena Van Swygenhoven, Steven Van Petegem, Cécile Renée Maria Marichal

Low-temperature deformation of body-centered cubic metals shows a significant amount of plastic slip on planes with low shear stresses, a phenomenon called anomalous slip. Despite progress in atomistic modeling of the consequences of complex stress states ...

Persistent conductive footprints of 109 degrees domain walls in bismuth ferrite films

Nava Setter, Igor Stolichnov, Enrico Colla, Monika Iwanowska

Using conductive and piezoforce microscopy, we reveal a complex picture of electronic transport at weakly conductive 109 degrees domain walls in bismuth ferrite films. Even once initial ferroelectric stripe domains are changed/erased, persistent conductive ...
