Product spaces and the stone-weierstrass theorem
AbstractA space X is said to be completely Hausdorff if C(X), the set of bounded continuous real valued functions defined on X, is point separating. A completely Hausdorff space X is called an SW space if every point separating subalgebra of C(X) which contains the constants is uniformly dense in C(X).The purpose of this paper is to show that there ...

Advances in Magnesium‐Based Thermoelectrics: A Critical Review
Magnesium‐based thermoelectric materials have emerged as promising candidates for low‐to‐mid‐temperature energy conversion due to their abundance, low cost, and competitive performance. This review summarizes recent advances in Mg3X2, MgAgSb, and Mg2X systems, covering transport mechanisms, fabrication strategies, stability challenges, and device ...

Separation properties of the Wallman ordered compactification
The Wallman ordered compactification ω0X of a topological ordered space X is T2-ordered (and hence equivalent to the Stone-Čech ordered compactification) iff X is a T4-ordered c-space.

Some aspects of sacral space markering in the Ural territory
The article analyses different aspects of organization of space as its sacred points — sacred places. Ancient sanctuaries were situated exactly in those marked points: caves, grottos, awnings, mountain peaks, rocks, hills, bald mountains, stone capes ...

Ultra‐High‐Throughput Discovery of Multifunctional Polyphenolic Coatings on Droplet Microarrays
An ultra‐high‐throughput (UHT) combinatorial strategy enables the miniaturized synthesis and screening of ≈30 000 polyamine‐polyphenolic (PaPp) coatings using droplet microarrays (DMA). This approach reveals hundreds of previously unknown fluorescent, redox‐active, and antibacterial materials, including multifunctional, cell‐compatible surfaces ...

Saturated boolean algebras and their stone spaces
For \(\kappa\geq \omega\), a Tychonoff space X is called \(\kappa\)- Parovichenko if (1) X is compact and zero-dimensional, and (2) the Boolean algebra CO(X) of clopen subsets of X is \(\kappa\)-saturated and satisfies \(| CO(X)| =\kappa^{

A multifunctional heparinized polyamide membrane embedded with graphene quantum dots (GQDs) and hyperbranched polyethyleneimine (HPEI) is engineered for efficient bilirubin removal via a one‐step anticoagulation–adsorption process. The membrane demonstrates enhanced hemocompatibility, prolonged clotting times, and high bilirubin adsorption capacity ...

Simple Synthesis of Entropy Stabilized Oxides Single Crystal Films
Diffusion‐controlled enables the creation of a single‐crystal thin film of Entropy‐stabilized oxides (ESO). ABSTRACT Entropy‐stabilized oxides (ESO) have emerged in the last decade as a new class of metastable materials with promising functional properties.
