Weak Solutions for a Class of Nonlocal Singular Problems Over the Nehari Manifold

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a nonlocal model of dilatant non‐Newtonian fluid with a Dirichlet boundary condition. By using the Nehari manifold and fibering map methods, we obtain the existence of at least two weak solutions, with sign information.

A Numerical Method Combining Cubic Interpolated Propagation and Shifted Grünwald–Letnikov for Fractional Advection–Dispersion Equations

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Recent advances in the numerical solution of fractional partial differential equations have yielded promising results. In particular, the Shifted Grünwald–Letnikov (SGL) approach allows for a generalization of the traditional finite difference method to the context of fractional differential equations.

Capturing Complex Rate‐Dependent Behaviors of Saturated Clays: A Fractional Consistency Kinematic Hardening Viscoplastic Approach

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Saturated high plasticity clays show complex nonlinear, rate‐dependent, and hysteresis behaviors under non‐monotonic stress paths, requiring advanced mathematical constitutive equations for accurate description. Taking into account the inherent advantages of kinematic hardening mechanisms in simulating complex stress histories, this paper ...

Self‐Assembled Conjugated Hollow Fibers for Spongy Monoliths Toward Solar‐Driven Desalination and Hydrovoltaic Electricity Generation

open access: yesSmall, EarlyView.
A self‐assembled conjugated hollow fiber monolith enables simultaneous solar‐driven desalination and hydrovoltaic electricity generation. Metal‐free polymerization produces cross‐linked hollow fibers that entangle into a porous monolith, followed by gradient polypyrrole coating for efficient light absorption and directional water transport.

Distorted Ultrasmall TiO2 Nanoparticles as Efficient Visible Light Photocatalyst

open access: yesSmall, EarlyView.
The visible‐light absorption of ultrasmall TiO2 nanoparticles is attributed to lattice distortion, which induces band broadening and modifies the electronic structure of TiO2 and enhanced NO photocatalytic performance. ABSTRACT Developing efficient and low‐cost visible light photocatalysts remains a fundamental challenge.
