, 2020 In this paper, we introduce and explore γ-S-closed spaces. It is evident by definition that γ-S-closed space coincides with γ-s-closed space, if the underlying space is γ-extremally ...

F-Spaces and Substonean Spaces General Topology as a Tool in Functional Analysis
, 1989 K. Grove and G. Pedersen define a substonean space to be a locally compact (Hausdorff) space in which disjoint σ-compact open subspaces have disjoint compact closures.

Indium‐Mediated Glue‐Like Interlayer Enables Stable High‐Capacity Flexible Sodium Metal Batteries
Advanced Materials, EarlyView.A three‐dimensional Na‐In‐S/Cu composite interlayer is constructed on a flexible current collector via an In‐mediated in situ reaction. Featuring abundant Na nucleation sites and a low diffusion barrier, this interlayer enables rapid and uniform Na deposition.

On n-to-one continuous images of ßℕ
, 2007 Eric van Douwen [5] produced a maximal crowded extremally disconnected regular space and showed that its ech-Stone compactification is an at most two-to-one image of . We construct for any n 3 an example of a compact crowded space

Advanced Materials, EarlyView.A titania‐supported Co1/Ru single‐atom alloy catalyst enables efficient polypropylene hydrogenolysis. Ru─Co─Ru motifs maintain Ru activity while suppressing excessive chain scission to gaseous products. Both virgin and waste plastics achieve high, environmentally and economically optimal C11+ liquid yields, supporting sustainable chemical recycling ...

Zero-dimensional proximities and zero-dimensional compactifications
, 2009 We introduce zero-dimensional proximities and show that the poset 〈Z(X),⩽〉 of inequivalent zero-dimensional compactifications of a zero-dimensional Hausdorff space X is isomorphic to the poset 〈Π(X),⩽〉 of zero-dimensional proximities on X that induce the

Advanced Materials, EarlyView.A double‐sided mechanical interlocking strategy is developed to create robust electrical contact between polymer electrode and metal interconnect. The fibrous structure enables formation of thread–hole adhesion, which only breaks under bulk failure and achieves a record high interfacial energy exceeding 730 J·m−2. This adhesion secures the integrity of

Permutable pairs of quasi-uniformities
, 2011 We continue investigating the lattice (q(X),⊆) of quasi-uniformities on a set X. In particular in this article we start investigating permutable pairs of quasi-uniformities.

Near‐Unity Chiral Lasing Enabled by Quasi‐Bound States in the Continuum
Advanced Materials, EarlyView.Nanoimprinted chiral array that supports bound states in the continuum is doped with an efficient non‐chiral molecule (Rhodamine‐B) acting as gain medium to produce fully circularly polarized lasing emission. The chiral lasing wavelength can be tuned across the emission band of Rhodamine‐B by adjusting the coating thickness of the TiO2 high refractive ...

Embeddings into pseudocompact spaces of countable tightness
, 2004 A method for embedding certain countable spaces into a pseudocompact Tychonoff space of countable tightness is given. In particular, this permits construction under [CH] of two pseudocompact Tychonoff spaces of countable tightness, one does not have ...
