Physics Opportunities with the FCC-hh Injectors [PDF]

, 2017
In this chapter we explore a few examples of physics opportunities using the existing chain of accelerators at CERN, including potential upgrades. In this context the LHC ring is also considered as a part of the injector system.

Phonon instabilities in high-pressure bcc-fcc and the isostructural fcc-fcc phase transitions of Cs [PDF]

Physical Review B, 2000
The phonon instabilities of cesium related to its pressure-induced $\mathrm{bcc}\ensuremath{-}\mathrm{to}\ensuremath{-}{\mathrm{fcc}}^{(1)}\ensuremath{-}\mathrm{to}\ensuremath{-}{\mathrm{fcc}}^{(2)}$ phase transitions are studied using the density-functional perturbation theory.

Composition‐Tuned Enhancement of the Anomalous Nernst Effect in FeCo–Pt Thin Films on Rigid and Flexible Substrates

Advanced Engineering Materials, EarlyView.
Disordered (Fe50Co50)1−xPtx thin films exhibit a pronounced anomalous Nernst effect (ANE) with a strong composition dependence on both rigid and flexible substrates. The transverse thermoelectric response peaks near 22.5 at.% Pt, accompanied by enhanced αxy/σxy scaling, thermal transport, and ANE sensitivity.

Combined Process‐ and Phase‐Field‐Simulation to Predict the Microstructure of Single‐Crystal Ni‐Based Superalloys

Advanced Engineering Materials, EarlyView.
A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

As trajetórias escolares: percepções de crianças/alunos e professoras

Doxa, 2017
Pode-se dizer que há dois eixos centrais que perpassam o conceito de infância. O primeiro é a socialização, atrelada principalmente às instituições sociais, como a escola e a família, em que adultos ensinam maneiras de ser e agir em sociedade para a ...

Low‐Angle Grain Boundaries and Re‐Segregation in Single‐Crystalline Ni‐Base Superalloys

Advanced Engineering Materials, EarlyView.
This work demonstrates that Re‐segregation at low‐angle grain boundaries (LAGBs) in Ni‐base superalloys is influenced by misorientation angle. Advanced microscopy and atom probe tomography reveal that higher misorientation angles increases Re‐segregation.

BFACF-style algorithms for polygons in the body-centered and face-centered cubic lattices

, 2010
In this paper the elementary moves of the BFACF-algorithm for lattice polygons are generalised to elementary moves of BFACF-style algorithms for lattice polygons in the body-centred (BCC) and face-centred (FCC) cubic lattices.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

Advanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.
