Prediction of structure and phase transformations
This chapter introduces calculational methods that can be used for abinitio structure prediction in multicomponent alloy systems, with an emphasis on concepts relevant to high entropy alloys. Specifically we will address density functional-based calculation of T=0K total energies. Extension to finite temperature will use cluster expansions for the energies to obtain the chemical substitution en...
متن کاملMetal-Metal Bonding in Uranium-Group 10 Complexes.
Heterobimetallic complexes containing short uranium-group 10 metal bonds have been prepared from monometallic IU(IV)(OAr(P)-κ(2)O,P)3 (2) {[Ar(P)O](-) = 2-tert-butyl-4-methyl-6-(diphenylphosphino)phenolate}. The U-M bond in IU(IV)(μ-OAr(P)-1κ(1)O,2κ(1)P)3M(0), M = Ni (3-Ni), Pd (3-Pd), and Pt (3-Pt), has been investigated by experimental and DFT computational methods. Comparisons of 3-Ni with t...
متن کاملHydrogen triggered exothermal reaction in uranium metal
An exothermal reaction has been observed when submitting metallic uranium to the combined action of a magnetic field and an electrical current. The set-up used to study the phenomenon is described and results are given. A tentative explanation is given, based on the possible existence of a still hypothetical proton/electron resonance.
متن کاملTopological Phase Fields, Bäcklund Transformations, and Fine Structure
Quantum coupling is defined by comparing the evolution of an input to an output phase, where the phase is evolving on a curved pseudospherical surface. The difference given by interference obeys a single-valuedness condition since the output phase is coupling back to the input phase. We arrive at Bäcklund transforms and corresponding sine-Gordon soliton equation. The idealized resonance or feed...
