Water‐Coupled Interfacial Modulation Enhances Photovoltaic and Pyroelectric Responses in Transparent Self‐Powered ZnO/NiO Photodetectors

Advanced Science, EarlyView.
Direct water contact enhances the performance of a transparent self‐powered FTO/ZnO/NiO/AgNW/ZnO UV photodetector. Reduced surface reflection improves optical transmission, while an electric double layer at the ZnO/water interface modulates interfacial electrostatics and promotes charge separation.

Quantifying Structure‐Dependent Rigidity of 3D DNA Origami Boxes

Advanced Intelligent Systems, EarlyView.
We investigate the mechanical stability of a hollow 3D DNA origami box during assembly using liquid AFM imaging and finite element simulations. As structural completeness increases from flat sheets through intermediate assemblies to a closed box, rigidity improves.

Residual Strength Prediction of Chemically Reactive Two‐Phase Nanofluid Flow in a Bingham–Papanastasiou Rheological Theory Using a Morlet‐Based Wavelet Neural Network Approach

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The behavior of nanofluid flow involving a zero‐mass flux condition has received considerable interest because of a realistic scenario. In reality, this condition confines the optimistic accumulation or disappearance of nanoparticles past a sheet, constructing a more physically realistic demonstration through several applications, such as heat

Justification of the Cauchy-Born approximation of elastodynamics [PDF]

, 2013
We present sharp convergence results for the Cauchy-Born approximation of general classical atomistic interactions, for static problems with small data and for dynamic problems on a macroscopic time ...

Physical Properties of Transition Metal Hydride Superconductors Mg2TmH6 (Tm = Rh, Pd, Ir, Pt) by First‐Principles Calculations

Advanced Physics Research, EarlyView.
The electronic band structure determines all the charge transport properties of crystalline solids. It also controls the optical response of the material. Bonding characters are strongly influenced by the band structure. The band structures of Mg2TmH6 (Tm = Rh, Pd, Ir, Pt) compounds shown above confirm their metallic nature.

Optimization of 3D‐Printed Structured Packings—Current State and Future Developments

Chemie Ingenieur Technik, EarlyView.
This paper gives an overview about structured packing development for distillation, surveying heuristic development cycles, computational fluid dynamics simulations, and additive manufacturing techniques. The emerging application of shape optimization to improve packings is emphasized, and its benefits, impact, and limitations are discussed.

Strongly Lacunary I?-Convergence and Strongly Lacunary I?-Cauchy Sequence [PDF]

In this paper, we defined the concepts of lacunary I?-convergence and strongly lacunary I?-convergence. We investigated the relations between strongly lacunary I-convergence and strongly lacunary I?-convergence.

Front Propagation Through a Perforated Wall

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We consider a bistable reaction– diffusion equation ut=Δu+f(u)$u_t=\Delta u +f(u)$ on RN${\mathbb {R}}^N$ in the presence of an obstacle K$K$, which is a wall of infinite span with many holes. More precisely, K$K$ is a closed subset of RN${\mathbb {R}}^N$ with smooth boundary such that its projection onto the x1$x_1$‐axis is bounded and that ...

A Geometric Characterization of Steady Laminar Flow

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the steady states of the Euler equations on the periodic channel or annulus. We show that if these flows are laminar (layered by closed non‐contractible streamlines which foliate the domain), then they must be either parallel or circular flows.

Strong lacunary harmonic summability of fractional differences in q-rung orthopair fuzzy normed spaces

Demonstratio Mathematica
We study strong lacunary harmonic summability of fractional difference sequences in q-rung orthopair fuzzy normed spaces. The fractional difference is defined on its convergence domain, with an explicit sufficient condition and a truncation estimate for ...
