Engineering oxygen vacancies at the nanoscale is instrumental for controlling oxygen dynamics that underpin diverse functional behaviors in oxide materials. Here, we present a magnetic-field-assisted synthesis platform that leverages static magnetic fields (3 T) to actively engineer oxygen vacancies in gadolinium oxid…
This revised article addresses Q0027, 'Control interfacial assembly of nanoparticles and surfactants?' using a question-specific mathematical construction rather than a generic logarithmic template. The proposed model, termed the Interfacial Assembly Free-Energy Drift Model, uses surface coverage theta, particle order…
Abstract Sulfur hexafluoride (SF6) can be decomposed under electrical or thermal stress in gas-insulated switchgear (GIS), and the resulting byproducts pose safety risks and provide diagnostic signals. In this work, density-functional-theory calculations were used to evaluate gas-sensing descriptors for six representa…
Researchers at the Max Planck Institute for Polymer Research in Germany have published a review surveying the current state of quantum sensing that uses nitrogen-vacancy (NV) centers in nanodiamonds to detect free radicals. The review emphasizes that T1 relaxometry with NV centers can measure the local paramagnetic en…
Understanding the potential dependent thermodynamic properties and growth-dissolution kinetics of electrode-supported metallic clusters is essential in many situations. The classical approach to do so treats clusters as “droplets” of the metal that possess a constant surface tension. It is shown here that upon treatin…
FINDING: Project Euler hardest problems often reduce to graph theory (NP-complete clique search) or prime sum sieves with Riemann hypothesis implications. | MATH: Figurate number sequences: heptagonal numbers \( P_7(n) = \frac{n(5n-3)}{2} \); cyclic set condition: last digits of one figurate number match first digits…
Cationic covalent organic frameworks (COFs) hold great potential for ion conduction and catalysis, yet poor crystallinity from interlayer electrostatic repulsion severely limits their performance. Herein, we demonstrate that lattice-matched polyoxometalates (POMs) as multifunctional counterions can direct the crystall…
Abstract Glassy materials undergo physical aging, changing their physical properties as they approach thermodynamic equilibrium. When confined in nanopores, glass-forming systems exhibit peculiar behavior, including out-of-equilibrium phenomena observed on a molecular time scale much faster than in the bulk. This occu…

Medial ustunning buzilishi, metafizar komminutsiya va CALCAR defekti bloklovchi plastina bilan osteosintezda ikkilamchi varus deformatsiya, vintlarning bo‘g‘im ic…
The isotopic difference in the thermodynamics of hydration of 20 mol% Y-substituted BaZrO 3 with H 2 O or D 2 O has been investigated by thermogravimetry. Average standard entropies and enthalpies of hydration were extracted from linear regressions of van ‘t Hoff plots of hydration over the range 400–900 °C, further v…
Polylactic acid (PLA) is one of the most promising bio-based and biodegradable polymers, yet its inherent brittleness limits its application in flexible film products. This study compares three mixing strategies, applied as four sample series, to improve the mechanical performance of PLA-based binary blends: (1) singl…
ABSTRACT Thermal depolymerization is typically studied in bulk, yet many systems involve polymers confined within nanoscale geometries. Understanding how nanoconfinement alters radical depolymerization kinetics is essential for interpreting polymer stability in nanostructured environments. Here we show that thermal de…
Abstract Nanoscale quantum light sources are essential building blocks for integrated quantum photonic systems. Here, we report a wavelength-scale entangled-photon source based on van der Waals-engineered NbOBr2 and benchmark its performance for telecom-wavelength quantum light generation. By exploiting the material’s…
Ballistic impact involves the high-velocity interaction response of a projectile with a protective target, resulting in projectile deformation, target damage, and mass loss. The Finite Element Method (FEM) implemented in ANSYS/Autodyn was used to investigate the ballistic response of a Kevlar Fiber Reinforced Polymer…
The need to optimize photoluminescence (PL) signal-to-background ratios for demanding applications in bioanalysis and imaging has led to an ever-growing toolbox of light-emitting materials with diverse strengths and weaknesses. Although the long PL lifetimes of luminescent lanthanide complexes (LLCs) support time-gate…

Abstract Electrode plate contact abnormalities are one of the key factors affecting current efficiency in the zinc electrolysis process. Recent studies on infrared image-based detection of electrode plate contact abnormalities have demonstrated promising performance under conventional scenarios. However, in real indus…
