Solution to the monotonicity problem of an interesting class of sequences of real numbers

Journal of Inequalities and Applications
Recently we have presented some sufficient conditions so that the real sequence ( 1 + α n ) n + p $\big (1+\frac{\alpha }{n}\big )^{n+p}$ , n ∈ N $n\in {\mathbb{N}}$ , strictly increasingly converges to e α $e^{\alpha }$ , when 0 ≤ 2 p < α $0\le ...

Differential Sedimentation and Cryo‐TEM Mapping Resolve Structural Heterogeneity in Conjugated Polymer Nanowires for Programmable Stretchable Electronics

Advanced Materials, EarlyView.
Density‐driven differential sedimentation fractionates solution‐assembled P3HT nanowires into crystalline and disordered constituents. High‐resolution cryo‐TEM directly visualizes the molecular chain packing within individual nanowires in real space, and recombining the fractions programs the mobility–stretchability trade‐off without chemical ...

Monotonicity of Chi-square Test Statistics [PDF]

This paper establishes monotonicity of the chi-square test statistic. As the more efficient parameter estimator is plugged into the test statistic, the degrees of freedom of the resulting chi-square test statistic monotonically increase.

Positivity properties of scattering amplitudes

Journal of High Energy Physics
We investigate positivity properties in quantum field theory (QFT). We provide evidence, and in some case proofs, that many building blocks of scattering amplitudes, and in some cases the full amplitudes, satisfy an infinite number of positivity ...

1T‐to‐2H Phase Evolution During Epitaxial Growth of Transition Metal Dichalcogenides

Advanced Materials, EarlyView.
During MOCVD growth of MoS2 and WSe2, a transient metallic 1T phase emerges in early, edge‐rich, chalcogen‐deficient domains and declines as the films ultimately coalesce as 2H material. Together, experiments and ReaxFF simulations link domain size, edge stoichiometry, and vacancies to this evolution.

Breaking Bottlenecks in Solid Electrolyte Discovery With Large Artificial Intelligence Models

Advanced Materials, EarlyView.
Large AI models are presented as a route to break key bottlenecks in solid electrolyte discovery by linking materials databases, machine‐learning interatomic potentials, large language models, and autonomous experiments. This perspective highlights how AI can accelerate the identification of solid electrolytes with fast ion transport, stable interfaces,

From Dark Photocatalysis to Photobattery‐Type Operation: A Re‐Functionalized Ti‐MOF for Solar Energy Storage

Advanced Materials, EarlyView.
ReCl47‐bpy is developed as a solar‐rechargeable, Re‐functionalized two‐dimensional metal–organic framework (MOF) for light‐driven charge storage and dark utilization. Re–bipyridine sites stabilize photoinduced electrons, enabling two complementary configurations: a MOF suspension for long‐lived charge retention and dark H2 evolution, and a spin‐coated ...

A Family of Sodium Solid‐State Electrolytes Based on the NaGaxAl1‐xCl4 Solid Solution

Advanced Materials Interfaces, EarlyView.
ABSTRACT Sodium‐based metal chloride solid electrolytes are promising for sodium solid‐state batteries due to their excellent oxidation stability, which, as shown for Li halides, can coexist with high ionic conductivity. To explore cationic substitution effects, we synthesized NaGaxAl1‐xCl4 (0 ≤ x ≤ 1) via ball milling and investigated structural and ...

Surface Functionalization Modulates Collective Cell Behavior Near Topological Defects Induced by Topographical Patterning

Advanced Materials Interfaces, EarlyView.
Strongly adhered cells align with concentric circular ridges and exhibit predominantly tangential motion, whereas weakly adhered cells fail to follow topographical guidance and display enhanced radial inward motion. ABSTRACT Living cells establish long‐range orientational order through collective alignment, giving rise to topological defects whose ...
