Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

Advanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

Product spaces and the stone-weierstrass theorem

General Topology and its Applications, 1973
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 ...

An Ion‐Based Strategy Toward Synergistic Surface Functionalization Combining the Osteogenic Properties and NIR‐Mediated Antibacterial Activity of PEEK

Advanced Materials, EarlyView.
A multifunctional bioactive PEEK‐based implant (Mn@p/MBG‐SPEEK) is engineered to combat implant‐associated infections while promoting osteogenesis. The hybrid surface activates PI3K/Akt/mTOR and AP‐1 signaling pathways for osteogenic differentiation, while Mn coordination induces electronic coupling that narrows the HOMO‐LUMO energy gap and enhances ...

Separation properties of the Wallman ordered compactification

International Journal of Mathematics and Mathematical Sciences, 1990
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

Вестник археологии, антропологии и этнографии, 2018
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 ...

Saturated boolean algebras and their stone spaces

Topology and its Applications, 1985
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^{

Anomalous Crystallinity and Magnetism in Chemically Disordered Coherent Heterostructures

Advanced Materials, EarlyView.
Coherent isostructural high‐entropy oxide heterostructures are realized despite remarkable >5% interfacial lattice distortion. The resulting buried interface exhibits abrupt valence reconstruction which contributes to 2 × enhanced exchange bias in the heterostructure relative to constituent layers, demonstrating how chemical disorder enabled anomalous ...
