Quantum Geometric Moment Encodes Stacking Order of Moiré Matter

open access: yesAdvanced Materials, EarlyView.
The Berry curvature dipole (BCD) changes across valley Chern transitions. A new electrical technique is developed to use such BCD sign flips for distinguishing the stacking order of a moiré material, namely twisted double bilayer graphene. Such a method, analogous to spectroscopic techniques, establishes a link between quantum geometry and stacking ...

On supra soft topological ordered spaces

open access: yesArab Journal of Basic and Applied Sciences, 2019
In this work, we initiate the concept of supra soft topological ordered spaces which are consider as an extension of the concept of soft topological ordered spaces.

On Topological Groups of Automorphisms [PDF]

open access: yesarXiv
We study spaces $X$ for which the space $Hom_p(X)$ of automorphisms with the topology of point-wise convergence is a topological group. We identify large classes of spaces $X$ for which $Hom_p(X)$ is or is not a topological group.

On the topological equivalence of S-metric and cone S-metric spaces [PDF]

open access: yesarXiv, 2017
The aim of this paper is to establish the equivalence between the concepts of an $S$-metric space and a cone $S$-metric space using\ some topological approaches. We introduce a new notion of $TVS$-cone $S$-metric space using some facts about topological vector spaces.

Revisiting the “Stick‐Slip” Process via Magnetism‐Coupled Flexible Sensors with Bioinspired Ridge Architecture

open access: yesAdvanced Materials, EarlyView.
A sandwich‐like device for stick‐slip perception is developed, featuring a deformable bioinspired ridge layer with capability of lateral deformation and fast recovery. Coupled with magnetized functionality, the morphological transformation is capable to induce periodical electrical pulses which allows to revisit the stick‐slip process when human ...

Heterostructured Electrocatalysts: from Fundamental Microkinetic Model to Electron Configuration and Interfacial Reactive Microenvironment

open access: yesAdvanced Materials, EarlyView.
Heterostructures have emerged as advanced electrocatalysts to convert earth‐abundant simple molecules into high‐value‐added products. On the basis of atomistic understanding to accelerate the electrochemical processes, the architecture of heterostructured electrocatalysts is comprehensively discussed from the point of view of modulating electronic ...
