C- sets and decomposition of continuity in generalized topological spaces

open access: yesBoletim da Sociedade Paranaense de Matemática, 2013
In generalized topological spaces, we dene $\mu C- sets and establish some decomposition of continuity between generalized topological spaces. Moreover, we prove that some of the results established in [3] are already established results in topological ...

Countable Fuzzy Topological Space and Countable Fuzzy Topological Vector Space

open access: yesJournal of Mathematical and Fundamental Sciences, 2015
This paper deals with countable fuzzy topological spaces, a generalization of the notion of fuzzy topological spaces. A collection of fuzzy sets F on a universe X forms a countable fuzzy topology if in the definition of a fuzzy topology, the condition of

Interfacial Interaction‐Mediated Regulation of Metal Oxidation States for Enhanced CO2 Reduction

open access: yesAdvanced Functional Materials, EarlyView.
A hybrid strategy is employed to optimize bismuth–oxygen interactions, precisely regulating interfacial bismuth–oxygen bonds during topochemical synthesis. This leads to vanadium oxynitride‐bismuth catalyst exhibiting high Faradaic efficiency and durability for formate production, attributed to enhanced reaction thermodynamics and kinetics.

Functional product topology: A common framework of the topological sum, the product topology and the functional topology of pointwise convergence

open access: yesJournal of Hebei University of Science and Technology, 2015
Based on the topological sum, for X being a discrete topological space, we prove that the product topology generated by some topological spaces is equal to the topology of pointwise convergence related to X.

Engineering a Spin‐Orbit Bandgap in Graphene‐Tellurium Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
Tellurium intercalation in epitaxial graphene on Ir(111) enables the emergence of a spin–orbit‐induced bandgap with energy spin splitting. By combining STM, ARPES, spin‐resolved ARPES, and DFT, two structural phases are identified, both exhibiting tunable electronic doping.

Local homogeneity in fuzzy topological spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
Three types of local homogeneity in L-topological spaces are introduced and studied, and each is characterized and proved to be a good extension of local homogeneity in ordinary topological spaces. Many implications concerning them are introduced.

Spin‐Selective Anisotropic Magnetoresistance Driven by Chirality in DNA

open access: yesAdvanced Functional Materials, EarlyView.
It is shown that magnetoresistance (MR) measurements carried out as a function of angular dependence between the magnetic field and a chiral (DNA) interface provide a valuable new insight into the charge transport mechanism associated with the chiral‐induced spin selectivity (CISS) effect.

Topological Structure of Vague Soft Sets

open access: yesAbstract and Applied Analysis, 2014
We introduce vague soft topological spaces which are defined over an initial universe with a fixed set of parameters. The notions of vague soft open sets, vague soft closed sets, vague soft interior, vague soft closure, and vague soft boundary are ...

Optical Control of the Thermal Conductivity in BaTiO3

open access: yesAdvanced Functional Materials, EarlyView.
Light‐driven manipulation of thermal conductivity in archetypal ferroelectric, BaTiO3, offers a novel and effective approach for the dynamical control of the heat flux, with potential applications in thermal management and phonon‐based logic. Abstract Achieving dynamic control over thermal conductivity remains a formidable challenge in condensed matter
