Transition-Metal Cation Effects on Electrodeposited Ni(OH)2 for Urea Electrolysis
Urea electrolysis couples the anodic urea oxidation reaction (UOR) with the cathodic hydrogen evolution reaction (HER), making the balance between the two half-reactions critical to bifunctional electrode selection. Here, Ni(OH)2 supported on nickel foam (NF) was systematically compared with electrode series prepared…
Global Solutions to a Fourth-order Degenerate Model for Surface-Tension-Driven Convection
This paper investigates the global existence and non-negativity of weak solutions to an initial-boundary value problem for a one-dimensional fourth-order nonlinear degenerate parabolic equation. This model governs the convection phenomena in thin films driven by surface tension. Our analytical approach begins with the…
Towards Computational Provenance: Carrying Causal-State Evidence in Generated Text
A language model's output does not by itself provide verifiable evidence about the internal computation that produced it. We study computational provenance: whether generated text can carry detectable evidence of which causally relevant internal state occurred. We test a bounded form of this idea in two controlled arc…
Casimir force between plane-layered structures: van Kampen-Schram approach for finite temperature
Based on the van Kampen-Schram method, a formula for the Casimir force between two plane-layered structures is obtained, which includes the sum of the Matsubara frequencies and a contour integral. It is shown that the contour integral is not taken into account in the Lifshitz formula. Taking it into account gives a sm…
Charge-density-wave at elevated temperatures in 1T-TaS2 ink-printed devices
We present results from low-frequency noise and current–voltage measurements on an ink-printed 1T-TaS2 layer on a ceramic substrate, situated between interdigitated platinum electrodes. The measurements were conducted at elevated temperatures and under UV exposure. A charge-density-wave (CDW) phase transition was dete…
Exact mobility rings in non-Hermitian quasiperiodically decorated Lieb lattices
The mobility ring (MR), a critical boundary in the complex energy plane separating extended and localized states, is fundamental to understanding the Anderson transition in non-Hermitian (NH) disordered systems. While MRs have been extensively studied in one-dimensional (1D) NH quasiperiodic models, rigorous analytica…
Thermodynamic analysis on para-ortho hydrogen conversion and chemical energy recovery coupled in vapor-cooled shield for liquid hydrogen storage
A liquid hydrogen storage has been widely applied due to its high volumetric hydrogen density and purity, yet achieving overall efficient hydrogen storage remains a key challenge for the widespread adoption of hydrogen energy. The significant temperature difference between liquid hydrogen and the ambient environment r…
Gradient growth and relaxation to jump profiles for 3-fold symmetric scale-invariant Euler flows
We consider the zero-homogeneous reduction of the two-dimensional Euler equation in the 3-fold symmetric case $m=3$, which is left unsolved in the $m\geq4$ relaxation theory of Said, Elgindi, and Murray \cite{EMS}. We prove that every nonconstant $W^{1,p}$ solution satisfies $\|g_θ(t)\|_{L^p}\to\infty$ as $t\to\pm\inf…
Statistical Mechanics of a Quantum Harmonic Oscillator with Folded Gaussian Frequency
A self-contained statistical-mechanics treatment of a single quantum harmonic oscillator is presented, whose frequency $ω$ is drawn from a folded Gaussian distribution: $ω=|ξ|$ with $ξ\sim\mathcal{N}(μ,σ^2)$. The exact integral representations for the partition function, internal energy, free energy, heat capacity, an…
Genesis of Chromitites in the Andriamena Greenstone Belt (Madagascar): Petrogenetic and Tectonic Implications
Abstract Apart from the well-known stratiform and podiform chromite deposits, those in the Archean greenstone belts are also of great importance to both researchers and the mining industry due to their unique occurrences and critical economic value. Chromitites from the Andriamena greenstone belt are associated with p…
Unlocking high-sulfur-content cathodes by an all-in-one high-entropy sulfide catalyst for all-solid-state Li-S batteries
Abstract Transition-metal sulfide (TMS) catalysis is a promising strategy for accelerating sulfur redox kinetics, yet its catalytic mechanisms in all-solid-state lithium-sulfur batteries (ASSLSBs) remain poorly understood. Here, two distinct catalytic failure modes are identified in conversion-type and intercalation-t…
Resolving the Magnetic Ground State and Field-Induced Transitions in Magnetic Dirac Semimetal Candidate EuMnSb$_2$
The magnetic structure of a magnetic topological semimetal EuMnSb$_2$ is investigated in fields up to 30 T using polarized and unpolarized neutron diffraction, pulsed-field x-ray magnetic circular dichroism and pulsed-field magnetometry. We determine the zero-field magnetic structures of the Eu and Mn sublattices, and…
Effect of Shot Peening on the Corrosion Behavior of 304 Austenitic Stainless Steel in Molten Solar Salt
ABSTRACT The effect of shot peening on the corrosion behavior of 304 austenitic stainless steel in molten Solar Salt (60 wt% NaNO 3 + 40 wt% KNO 3 ) at 550°C was studied. Shot peening markedly improves the corrosion resistance of 304 austenitic stainless steel. Electrochemical tests show a 35.2% reduction in corrosion…
Direct Access to Poly(amino ester)s with Main-chain H-bonding Motifs
We report a novel alternating copolymerization of epoxides and N-carboxyanhydrides as a direct synthetic route to polyesters bearing hydrogen-bonding motifs in their main chain, thereby enabling the straightforward synthesis of a previously inaccessible class of poly(amino ester)s featuring secondary amines. Conventio…
Experimental and Numerical Evaluation of a Shaped Charge Loaded With a Modified Insensitive Explosive Composition
ABSTRACT In the last decade, insensitive munitions (IMs) have attracted considerable attention because they offer a desirable combination of strong operational effectiveness and enhanced safety characteristics. This study explores the application of a DNAN‐based insensitive explosive composition (IEX) as an explosive…
LASSBio-classFLOW: A Semi-Automated KNIME Workflow for Classification Model Benchmarking and Virtual Screening
Machine learning–based quantitative structure–activity relationship (ML-QSAR) modeling requires consistent data preparation, validation, and model comparison. We present LASSBio-classFLOW, an open, modular, and semi-automated KNIME workflow for classification-based ligand screening. It integrates basic molecular struc…
Synthesis of 360° cylindrical optical wavefronts with controlled polarization
A procedure for generating secondary electromagnetic sources with controlled polarization on the surface of a cylinder is proposed and carried out experimentally. The method is based on reflecting a light beam from the outer surface of a conical mirror with an apex angle of 45°. Uniformly and non-uniformly completely…
Insights into the Structural and Orientational Ordering of 2D Metal Halide Perovskites
Metal halide perovskite nanoplatelets combine quantum confinement with structural anisotropy, yet how thickness and processing govern their internal crystal lattice versus collective organization remains unresolved. In this study, we separate internal structure, superlattice organization, and film texture using 2-5 mo…
