Neutrosophic αψ-Homeomorphism in Neutrosophic Topological Spaces

Inf., 2018
In this article, the concept of neutrosophic homeomorphism and neutrosophic αψ homeomorphism in neutrosophic topological spaces is introduced. Further, the work is extended as neutrosophic αψ∗ homeomorphism, neutrosophic αψ open and closed mapping and ...

On resolvability of topological spaces

Topology and its Applications, 2002
A space \(X\) is \(\kappa\)-resolvable if it can be represented as the union of \(\kappa\)-many mutually disjoint dense subsets. It is maximally resolvable if it is \(\Delta(X)\)-resolvable, where \(\Delta(X)\) is the dispersion character of \(X\). The pseudospread, \(\text{ps}(X)\), (respectively, pseudoextent, \(\text{pext}(X)\)) of a space \(X\) is ...

Multimodal Characterization of Sn‐Bi Solder Alloy Solidification Using Synchrotron X‐Ray Microtomography and Energy Dispersive Diffraction

Advanced Engineering Materials, EarlyView.
Real‐time imaging and energy‐dispersive diffraction during solidification of Sn‐Bi alloy interconnect for electronic packaging applications are studied. Sn‐Bi solder alloys have generated significant interest in recent times due to their potential use in electronic packaging.

KC-bitopological spaces

AIMS Mathematics
A topological space $ \left(X, \tau \right) $ is called a $ KC $-space when every compact subset of $ X $ is closed. The aim of this paper is to introduce new, namely $ KC $-bitopological spaces and pairwise $ KC $-topological spaces "$ P $-$ KC ...

Ultrahigh Piezoelectricity in Truss‐Based Ferroelectric Ceramics Metamaterials

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
By leveraging the unique combination of polarization direction and loading state, ultrahigh piezoelectricity is achieved through careful tuning of the relative density and scaling ratio in truss‐based ferroelectric metamaterials. This approach enables the simultaneous realization of extremely high piezoelectric constants and ultralow dielectric ...

Optical Control of the Thermal Conductivity in BaTiO3

Advanced 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

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

Journal 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.

Terahertz‐Driven Ultrafast Dynamics of Rare‐Earth Nickelates by Controlling Only the Charge Degree of Freedom

Advanced Functional Materials, EarlyView.
The THz drive of the Mott insulating state of a rare‐earth nickelate induces instantaneous insulator‐metal transition via quantum tunneling of valence electrons across the bandgap. This transition is pure electronic and highly non‐thermal, which may find its applications in ultrafast opto‐electronics with enhanced performance and minimal device size ...

Local homogeneity in fuzzy topological spaces

International 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.
