Transitional Structures with Continuous Variations in Atomic Positions from Anatase to Rutile Improve Photocatalytic Activity

Advanced Materials Interfaces, 2023
TiO2 polymorphs have distinct properties that are widely employed in various applications. However, mechanisms of transformations between these polymorphs are not fully understood, especially at atomic scale, inhibiting advancing the design and ...

Gamma-convergence of a gradient-flow structure to a non-gradient-flow structure

Calculus of Variations and Partial Differential Equations, 2022
AbstractWe study the asymptotic behaviour of a gradient system in a regime in which the driving energy becomes singular. For this system gradient-system convergence concepts are ineffective. We characterize the limiting behaviour in a different way, by proving $$\Gamma $$ Γ -convergence of the so-called energy ...

Shifting paradigms: gradient structure in morphology [PDF]

Trends in Cognitive Sciences, 2005
Morphology is the study of the internal structure of words. A vigorous ongoing debate surrounds the question of how such internal structure is best accounted for: by means of lexical entries and deterministic symbolic rules, or by means of probabilistic subsymbolic networks implicitly encoding structural similarities in connection weights.

Magnetoelectric gradient structures

Journal of Physics: Conference Series, 2021
Abstract This work is a comprehensive theoretical study of a new class of structures – magnetoelectric gradient structures, which are a product of the integration of magnetoelectric mutliferroic layered structures and an artificial dielectric.

Simulation-Based Development of Gradient Woven Fabrics for Biomimetic Implants to Restore Tendons and Ligaments

Textiles, 2022
Tendons and ligaments are complex tissues that are necessary for human movement. Injuries occur very commonly and treatment quite often requires implants.
