The dynamic interplay between structure, anastructure and antistructure in extraordinary experiences
Journal of Business Research, 2016 Abstract Through an interpretive investigation of a religious pilgrimage, we explore the dynamic processes at play when consumers navigate the continuum between structure and antistructure in extraordinary experiences. We do so by identifying anastructure, which is a conflict-laden transient category that lies between the poles of antistructure and ...

Vacancy-antistructure defect interaction diffusion in β-LiAl and β-LiIn
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 1988 Abstract The lithium mass transport mechanisms of the NaTl-type intermetallic compounds β-LiAl and β-LiIn were studied by using the pulsed-field-gradient (PFG) nuclear magnetic resonance (NMR) spin-echo technique over a temperature range of 297–485 K.

Antistructure disorder and its relation to dislocations in III–V semiconductors
Crystal Research and Technology, 1987 AbstractIntimate relationship between antistructure defects and dislocations occurs in GaAs which manifests itself as: (i) appearing of spatial correlation between grown‐in dislocations and the EL2 defects (component of the latter are AsGa antisites), (ii) similar suppression of the concentration of EL2 and dislocation density due to the doping with ...

High temperature antistructure disorder in undoped ZnS
Physica B: Condensed Matter, 2009 High temperature electrical conductivity (HTEC) under defined component vapor pressure was investigated in undoped ZnS. The appearance of different slopes on HTEC isotherms can be explained by a two-carrier conduction mechanism involving electrons and holes.

Electronic structure of antistructure Co atoms and Co-vacancies in CoAl
Solid State Communications, 1986 Abstract We report on self-consistent ab-initio calculations for the electronic structure of intrinsic defects in CoAl, i.e. antistructure (AS) Co atoms and vacancies on the Co sublattice. The calculations are based on the Korringa-Kohn-Rostoker (KKR) Green's function method and employ the local spin density approximation of the density functional ...

Concerted-exchange mechanism for antistructure pair defects in GaAs
Solid State Communications, 1999 Abstract We show via first principle calculations why the antistructure-pair (GaAs–ASGa) in the nearest neighbor (nn) configuration is not experimentally detected. A low energy barrier for the concerted exchange mechanism is seen to be responsible for the recovery of the ideal crystal structure.

A theoretical study of disorder in transition metal aluminides: Vacancies and antistructure atoms
European Physical Journal B, 1987 Korringa-Kohn-Rostoker-Coherent-Potential-Approximation (KKR-CPA) calculations were performed on FeAl and NiAl in the CsCl structure with various concentrations of vacancies on the transition metal sublattice and antistructure atoms on both sublattices. It is found that transition metal vacancies only bring about minor changes in the density of states,

Philosophical Magazine A: Physics of Condensed Matter, Structure, Defects and Mechanical Properties, 2002 Based on the Bragg-Williams approximation, a statistical-thermodynamic approach is presented for non-stoichiometric binary B2 phases with a pure anti-structure defect mechanism. Whereas in the original Bragg-Williams model only the state of long-range order is considered and no correlations are allowed in the arrangement of the point defects, short ...

Scripta Materialia, 1996 Nearly stoichiometric NiAl alloys are one of the promising candidate materials for high temperature applications. For clear understanding of the mechanical properties of these B2 ordered alloys, it is essential to know the structural properties of vacancies and antistructure atoms (atoms on the wrong sublattice).

Synthesis, characterization and antistructure modeling of Ni nano ferrite
AIP Conference Proceedings, 2018 We report the role played by cation distribution in determining magnetic properties by comparing dry gel, thermally annealed Ni ferrite prepared by sol-gel auto-combustion technique. X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Mossbauer spectroscopy were used to characterize the ...
