Toward Intelligent Multimodal Holography for Real‐Time Chemical Imaging of Dynamic Ion Separation

Advanced Intelligent Discovery, Volume 2, Issue 4, August 2026.
Intelligent multimodal holography integrates digital off‐axis holography, spectroscopic imaging, and AI‐driven reconstruction to visualize ion transport and chemical dynamics in real time. In this perspective paper, we outline how this approach enables label‐free, chemically specific monitoring of complex environments and discuss its potential to ...

Modeling and Analysis of Nonlinear Radiative and Electromagnetic Effects With Second‐Order Slip in Unsteady Hybrid Nanofluid Flow Past a Porous Stretching Surface

Engineering Reports, Volume 8, Issue 8, August 2026.
The current work examines the dynamics of the stagnation point flow of an unsteady hybrid nanofluid (Fe2O3–Cu/H2O) across an inclined porous stretching surface. It considers heat transfer, second‐order slip, electrical field, heat source/sink, mixed convection, and magnetic field effects, as well as linear and nonlinear radiation.

Computational Investigation of MHD Radiative Flow of Shape‐Dependent Al2O3$$ A{l}_2{O}_3 $$ and Fe3O4$$ F{e}_3{O}_4 $$ Nanofluids in A Semi‐Porous Channel

Engineering Reports, Volume 8, Issue 8, August 2026.
A computational study of unsteady MHD radiative nanofluid flow in a semi‐porous channel reveals that nanoparticle shape, volume fraction, and magnetic effects significantly influence velocity and heat transfer. Results highlight strong coupling between geometric, electromagnetic, and thermophysical parameters in optimizing thermal system performance ...

Non-Markovian Cosmic-Ray Pitch-angle Transport from Mirror Interactions

The Astrophysical Journal
Cosmic-ray pitch-angle transport in magnetohydrodynamic (MHD) turbulence is governed by the interplay between magnetic mirroring and gyroresonant scattering. We develop a guiding-center Langevin model with explicit mirror drift and gyroresonant diffusion

Rheological Modeling and Numerical Simulation of Annular Flow of a Drilling Mud Based on Local Materials: Theoretical Parametric Study

Engineering Reports, Volume 8, Issue 8, August 2026.
Numerical and analytical modeling of annular flow reveals the hydraulic performance of sustainable drilling muds formulated from Congolese kaolinitic clay, okra mucilage, and plant ashes. Yield stress enhances cuttings transport, while shear‐thinning behavior reduces pressure losses and pumping energy.

Quantifying resonant drive in resistive perturbed tokamak equilibria

Nuclear Fusion
Resonant drive in tokamaks is routinely quantified using a variety of different metrics that target different aspects of a resonant response to an external perturbation. Two of the most direct metrics, $\Delta_{mn}$ and $b_\mathrm{pen}$ , are widely used

Unsteady Magnetohydrodynamics Heat‐Generating Oldroyd‐B Nanofluid Flow in a Stretching Power Generator Duct Using the Crank–Nicolson Method

Engineering Reports, Volume 8, Issue 8, August 2026.
This study explores how a heat‐generating Oldroyd‐B nanofluid behaves inside an annular hydromagnetic power‐generator duct with a porous, axially stretching inner cylinder. The coupled flow, heat, mass, and magnetic‐field equations are solved using the Crank–Nicolson method.

Global gyrokinetic particle simulation of kinetic ballooning modes with energetic ions

Nuclear Fusion
Interactions between energetic ions (EIs) and kinetic ballooning modes (KBMs) are inevitable in fusion reactors characterized by high- β plasmas with a large population of alpha particles ( $\beta_h\sim\beta_{e,i}$ , where $\beta_{h,e,i} = 2\mu_0p_{h,e,i}
