Thermal Conductance and Mass Transport of Brinkman‐Type Nanofluids Across Porous Plates: A Prabhakar‐Fractional Approach

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The paper establishes an advanced computing algorithm to investigate the thermosolutal dynamics of an electrically conductive Brinkman‐type nanofluid that moves in a porous channel, and the fluid is acted on by an inclined magnetic field exerted externally.

The Progress of Orbitronics: The Enhancement of Orbital Torque Efficiency

Advanced Physics Research, EarlyView.
Orbit‐torque (OT) devices attract significant attention for their low‐power consumption and high stability in applications. This review systematically outlines strategies for enhancing OT efficiency. We categorize approaches into boosting orbital currents/torques and improving the orbital‐to‐spin conversion coefficient.

Fractional-order nonlocal wave propagation in hygro-piezo-photo-thermoelastic semiconductors with dual-moisture diffusion and laser excitation

Journal of Low Frequency Noise, Vibration and Active Control
This study investigates the propagation of coupled waves in a nonlocal hygro-piezo-photo-thermoelastic semiconductor medium subjected to dual-moisture diffusion and fractional-order heat conduction. The mathematical model incorporates the effects of long-

Wave propagation in a hygrothermoelastic half-space along with non-local variable

Journal of Applied Science and Engineering
This particular work is an effort to investigate the propagation of wave in hygrothermoelastic medium in the light of Eringen’s nonlocal theory of elasticity. The coupled wave equations in terms of displacement, temperature and moisture concentration are

Exact controllability to the trajectories for parabolic PDEs with nonlocal nonlinearities [PDF]

, 2019
This paper deals with the analysis of the internal control of a parabolic PDE with nonlinear diffusion, nonlocal in space. In our main result, we prove the local exact controllability to the trajectories with distributed controls, locally supported in ...

Global Continua of Positive Equilibria for some Quasilinear Parabolic Equation with a Nonlocal Initial Condition

, 2012
This paper is concerned with a quaslinear parabolic equation including a nonlinear nonlocal initial condition. The problem arises as equilibrium equation in population dynamics with nonlinear diffusion.

Reaction Diffusion Equations with Nonlocal Boundary and Nonlocal Initial Conditions

Journal of Mathematical Analysis and Applications, 1995
The author considers the existence, multiplicity, and asymptotic behavior of solutions for a reaction diffusion equation under nonlocal boundary and nonlocal initial conditions. The main results are the theorems about the existence of multiple solutions for both the time-dependent and the steady-state problems, and that each of the time-dependent ...

Boosting Electron‐Hole Charge Separation in CO2 Photoreduction through Fluoroporphyrin‐Linked Nickel(II)‐Acetylide Frameworks

Carbon Energy, EarlyView.
A NiII‐acetylide framework, H2TFPP‐Ni‐AF, demonstrates outstanding photocatalytic CO2 reduction performance: 13.16 mmol h−1 g−1 of CO with 97.9% selectivity. Synergistic interactions, including d‐p orbital hybridization within NiII‐bis(acetylide) moieties ( − C ≡ C−NiII(PBu3)2 − C ≡ C − ) and the efficient charge transport afforded by π‐conjugated ...

Nonlocal degenerate reaction-diffusion equations with general nonlinear diffusion term

Electronic Journal of Differential Equations, 2014
We study a class of second-order nonlocal degenerate semilinear reaction-diffusion equations with general nonlinear diffusion term. Under a set of conditions on the general nonlinear diffusivity and nonlinear nonlocal source term, we prove global ...
