Unmaking architecture : holding patterns for misfit matter
This project provides techniques for arranging materials after the demolition and unmaking of architecture. Rather than down cycling concrete into low value aggregate, melting float glass into opaque bottles or grinding up street trees into mulch, methods are shown for this material to be indexed, …

Emergent properties of misfit layer compounds from first principles.
Misfit layer compounds (MLCs) are heterostructures composed of rocksalt units stacked with few-layers transition metal dichalcogenides (TMDs). They host Ising superconductivity, charge density waves, and good thermoelectricity. However, research has mostly focused on specific compounds and …

Microscopy study of extreme lattice mismatched heteroepitaxy using interfacial misfit arrays
… the material relieves strain energy through misfit dislocations, defects and often threading dislocations, which vertically propagate to active regions of devices, thus leads to non-radiative recombination and damages device performance. The majority of the work done in this field has been …

Robust Bayesian inference via optimal transport misfit measures: applications and algorithms
… of transport–Lagrangian (TL) distances as loss/misfit functions: such distances can be understood as “graph-space” optimal transport distances, and they naturally disregard certain features of the data that are more sensitive to time warping. We show that, compared to standard misfit functions, …

A Misfit Mythology: Hanes Taliesin in English Literature and Culture in the Nineteenth Century
Although authors, poets, and scholars of the nineteenth century frequently cited Taliesin as the preeminent bard of Wales, Hanes Taliesin (HT)—particularly the Elphin section—was overshadowed by popular and academic engagement with other traditional tales. Irish and Welsh legends sparked plays, …

Misfit Between Motivational Style and Type of Job Demand as a Factor in Developing Occupational Stress
… theory (1976). Correlational data indicated that misfit was related to perceived work stress and the perception of poor coping ability. Stress-related illnesses were correlated with poor perceived ability to cope. There was an association between misfit and consideration to change jobs as a result …

AN EXPLORATION OF THE EFFECTS OF COGNITIVE MISFIT ON THE RELATIONSHIP BETWEEN PROBLEM-SOLVING ABILITY AND ACCOUNTING TASK PERFORMANCE
… particularly under conditions of cognitive misfit (Chan 1996). Cognitive misfit occurs when an accountant's cognitive style interacts with incongruent demands of the accounting task. Theory suggests the condition of cognitive misfit may explain empirical inconsistencies found in prior …

Effect of systematic variation in Co:Ni ratio on elemental partitioning, lattice misfit and oxidation behaviour of γ'-strengthened (Ni,Co)75Al5Ti5Cr15 (at.%) alloys
… neutron diffraction analysis, the γ-γ' lattice misfits of alloys 0-47Co were found to be positive at all test temperatures (ambient, 400, 600, 700 and 800°C) and the magnitude of lattice misfit increased as Co content increased from 0-38 at.%. Lattice misfit values decreased with increasing …

An Analysis of Non-Uniform Stress States in Finite Thin Film/substrate System: The Need of Full-Field Curvature Measurements
… thickness subjected to non-uniform isotropic misfit strain between film and substrate. We obtain the film stresses and system curvatures in terms of the misfit strains and thickness in thin films. We derive the film stresses and interface shear stresses in terms of system curvatures and film …

Accurate image reconstruction in radio interferometry
… between DFT and FFT dirty images. The 'Least-misfit' gridding function is proposed, so as to minimise the image misfit between the DFT and FFT dirty images, and this is implemented and tested. Given an identical support width, it outperforms the main-stream spheroidal function in the image …

Reaction Paths for Self-Organized Surface Roughening of Silicon-Germanium Alloys During Hydride Gas-Source Molecular Beam Epitaxy
… thicknesses greater than the critical value for misfit dislocation formation (tc ≃ 100 nm) to probe the effect of thetaH on cross-hatch formation. At t slightly larger than tc, surface roughness is dominated by single- and multiple-atomic-height steps associated with the interfacial misfits. …

Investigation of new synchrotron X-ray and neutron techniques for local crystallographic analysis of Ni-based single crystal superalloys
… their mechanical properties is the lattice misfit between the γ and γʹ phases. Consequently, extensive research has been dedicated to optimising lattice misfit values to achieve the desired mechanical performance. Accurate determination of lattice misfit is challenging due to the similar …

The potential for superlattice precipitate reinforcement in titanium-iron alloys
… phase precipitates. However, the lattice misfit between these phases is large in the binary system, which limits precipitate-matrix coherency, and may prevent full exploitation of the superlattice benefits. In principle, the lattice misfit may be tuned through compositional modification. …

Graphene-assisted spontaneous relaxation and direct CVD growth of graphene on III-V substrate
… thesis reports a unique mechanism of relaxing misfit strain in heteroepitaxial films that can enable effective lattice engineering. We have observed that heteroepitaxy on graphene-coated substrates allows for spontaneous relaxation of misfit strain owing to the slippery graphene surface while …
