Unitary representability of free abelian topological groups
Applied General Topology, 2008 For every Tikhonov space X the free abelian topological group A(X) and the free locally convex vector space L(X) admit a topologically faithful unitary representation. For compact spaces X this is due to Jorge Galindo.

Advanced Functional Materials, EarlyView.Auxeticity‑by‑Assembly converts freeform photovoltaics from cut‑defined layouts to assembly‑defined systems. Standardized interlocking units generate negative‑Poisson‑ratio, reconfigurable architectures, while hinge regions are wired by selectively activatable AgNW–GO@EGaIn composite interconnects and a folding‑enabled interconnector layer. A decimeter‑

On cofree S-spaces and cofree S-flows
Applied General Topology, 2012 Let S-Tych be the category of Tychonoff S-spaces for a topological monoid S. We study the cofree S-spaces and cofree S-flows over topological spaces and we prove that for any topological space X and a topological monoid S, the function space C(S,X) with ...

Local isometries of compact metric spaces [PDF]
Proceedings of the American Mathematical Society, 1982 By local isometries we mean mappings which locally preserve distances. A few of the main results are: 1. For each local isometry f f of a compact metric space ( M , ρ ) (M,\rho ) into itself there exists a unique decomposition of M M into disjoint open sets,

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy
Advanced Functional Materials, EarlyView.This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.

Cohomology Theories on Compact and Locally Compact Spaces
Revista Matemática Iberoamericana, 1986 The aim of this paper is to give an expository account of the uniqueness theorem for cohomology theories on the category of locally compact Hausdorff spaces and proper continuous functions. The uniqueness theorem can be applied to give a proof of the known result that the Chern character induces an isomorphism K(X)\(\otimes {\mathbb{Q}}\cong \check H ...

A compactification of locally compact spaces [PDF]
Proceedings of the American Mathematical Society, 1972 Every locally compact space X X has its topology determined by its 1-1 compact images and hence has a compactification ξ X \xi X obtained as the closure of the natural embedding of X X in the product of those images, just as the Stone-Čech compactification β X

Advanced Functional Materials, EarlyView.A synergistic electrolyte engineering strategy of employing ethyl acetate (EA) with vinylene carbonate (VC) as multifunctional additives is initially pioneered, making various as‐prepared high‐voltage wide‐temperature sodium batteries work well via the formation of a gradient and temperature‐robust interphase.

Atomic Layer Deposition in Transistors and Monolithic 3D Integration
Advanced Functional Materials, EarlyView.Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

One-point extensions and local topological properties
, 2013 A space $Y$ is called an extension of a space $X$ if $Y$ contains $X$ as a dense subspace. An extension $Y$ of $X$ is called a one-point extension of $X$ if $Y\backslash X$ is a singleton. P.
