Hierarchical MXene‐Derived NTP/C Nanohybrids for Cryogenic Sodium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A hierarchical MXene‐derived NaTi2(PO4)3/C nanohybrid enables efficient sodium‐ion storage down to −40°C by integrating fast ion–electron transport pathways with an ether‐based electrolyte. The system promotes dominant pseudocapacitive behavior and forms a robust inorganic‐rich SEI, collectively mitigating kinetic and interfacial limitations, thereby ...

Some results over thin--thick sets in cone locally convex spaces

open access: yesFixed Point Theory and Applications, 2011
In this article, it is investigated some concepts of normed space like norming, thin-thick sets in cone locally convex spaces. It is also worked some impacts of thick sets over the uniform quasi-boundedness principles in cone locally convex spaces such ...

Regeneration of Rhododendron luteum Sweet (Ericaceae) undergrowth after main clear cuttings in Ukrainian Polissia

open access: yesБіологічні студії
Background. The yellow azalea (Rhododendron luteum Sweet) is a relict species, fragmentally distributed in Ukraine, particularly in the Zhytomyr Polissia, covering an area of approximately 62.000 ha.

Low‐Profile, High‐Gain GRIN RF Lenses via Multi‐Material Vat Photopolymerization

open access: yesAdvanced Functional Materials, EarlyView.
We investigate the opportunity of leveraging multi‐material vat photopolymerization printing to manufacture intricate lenses exhibiting permittivity gradients that can increase signal gain in transmitted radiofrequency signals in the X‐ and Ku‐bands. Lenses produced with more distinct low‐loss materials (up to 5) can deliver an 18 dB signal gain with a

Double Fuzzifying Topogenous Space, Double Fuzzifying Quasi-Uniform Spaces and Applications of Dynamics Fuzzifying Topology in Breast Cancer

open access: yesJournal of New Theory, 2019
The main motivation behind this work is to introduce the notion of (2,L)-double fuzzifying topology which is a generalization of the notion of (2,L)-fuzzifying topology and classical topology.

Informational Holonomy Curvature and Its Discrete-to-Continuous Convergence

open access: yesInternational Journal of Topology
We introduce a notion of curvature based on informational holonomy. Let (M,g) be a smooth Riemannian manifold and let π:P→M be a bundle of state spaces equipped fibrewise with a smooth divergence Dx inducing an information metric gPx.

Interlayer Expansion of Bulk MoS2 via Top‐Down Organic Pillaring Enables Tunable Li+ Intercalation and Controlled Solvent Co‐Intercalation

open access: yesAdvanced Functional Materials, EarlyView.
Top‐down organic pillaring expands the interlayer spacing of bulk‐sized MoS2 particles while preserving the bulk morphology. Operando X‐ray diffraction and electrochemical dilatometry show that MoS2‐bulk undergoes solvent co‐intercalation in diglyme electrolyte, causing large structural expansion, while pillared, expanded MoS2 suppresses solvent uptake

Local properties of transitive quasi-uniform spaces

open access: yes, 2010
If (X,Ƭ) is a topological space, then a quasi-uniformity U on X is compatible with Ƭ if the quasi-uniform topology, Ƭu = Ƭ. This paper is concerned with local properties of quasi-uniformities on a set X that are compatible with a given topology on X ...
