Heteroatom‐Mediated Covalent Organic Framework Membranes With Nitrogen‐Enriched Nanochannels for Efficient Desalination

open access: yesAdvanced Science, EarlyView.
Heteroatom precursor engineering serves as a molecular‐level strategy to tailor hydrazide monomer reactivity and diffusion kinetics, enabling controlled assembly of highly crystalline COF membranes with ultramicroporous channels. The nitrogen‐enriched nanochannels deliver high water/ion selectivity via simultaneous water transport acceleration and ion ...

Control-translated Finsler-type structure and anisotropic Ginzburg-Landau models

open access: yesNuclear Physics B
This paper develops a geometric and analytical extension of the Finsler-Ginzburg-Landau framework by introducing a distributed control field acting as a translation in the tangent bundle.

Second order regularity for solutions to anisotropic degenerate elliptic equations

open access: yes
We consider solutions to degenerate anisotropic elliptic equations in order to study their regularity. In particular we establish second-order estimates and enclose regularity results for the stress field.

Twin‐Lever Multifunctional Meta‐Optics With High Longitudinal Tolerance

open access: yesAdvanced Science, EarlyView.
We introduce a single‐layer, CMOS‐compatible metasurface that allows for polarization‐programmable, achromatic broadband dual‐mode imaging with high longitudinal tolerance. The twin‐lever design combines bright‐field focusing and vortex‐based edge‐enhanced imaging while managing axial intensity distribution from 488 to 633 nm.

Well-Posedness of the Maxwell-Boltzmann System in a Bianchi Type III Space-Time

open access: yesAdvances in Pure and Applied Mathematics
This paper investigates the Maxwell-Boltzmann system in the framework of a Bianchi type III space-time. We conduct a rigorous mathematical analysis of the system, emphasizing its structural properties, functional setting, and energy estimates.

Sublattice‐Resolved Magnetoelastic Coupling and Opposing Pressure Responses in the Frustrated Magnetocaloric GdMn2O5

open access: yesAdvanced Science, EarlyView.
In GdMn2O5, sublattice‐resolved EXAFS and diffraction analysis reveal pronounced spin‐phonon coupling and an unexpected opposing pressure response: the Mn‐driven Néel temperature slightly decreases while the Gd‐sublattice ordering temperature rises under pressures up to 0.86 GPa.

Anisotropic drag force in finite-density QGP from charged rotating 5D black holes

open access: yesJournal of High Energy Physics
We study the drag force acting on a heavy quark in a holographic plasma with rotational anisotropy and finite density. The bulk dual is the CCLP black hole of five-dimensional minimal gauged supergravity, characterised by two independent rotation ...

High‐Performance Violet Phosphorene‐Based Device via Tellurium Doping‐Induced Contact Resistance Reduction

open access: yesAdvanced Science, EarlyView.
Tellurium substitution for phosphorus in violet phosphorus significantly reduces contact resistance, enhancing FET performance under ambient conditions. ABSTRACT Two‐dimensional materials have attracted much attention in various research fields. The phosphorene structures with various allotropes, another type of elemental 2D materials after graphene ...

Polarization Holographic 4D Phenotyping Reveals Nanoplastic Induced Dysfunction in Zooplankton

open access: yesAdvanced Science, EarlyView.
Contaminant‐induced dysfunction in complex aquatic organisms remains difficult to resolve across scales. Polarization Holographic Imaging Microscopy (PHIM) integrates polarization‐sensitive holography with computational volumetric reconstruction for label‐free phenotyping of zooplankton in natural seawater, revealing that nanoplastic stress drives ...

Existence and regularity of solutions for a singular anisotropic $(p,q)$-Laplacian with variable exponent

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
In this paper, we investigate the existence and regularity of positive solutions for certain singular problems that involve an anisotropic $\left(p,q\right)$-Laplacian-type operator and a singular term with a variable exponent, under zero Dirichlet ...
