Entropy generation and MHD flow characteristics of unsteady Williamson fluid toward a stagnation point over a vertical Riga plate

Partial Differential Equations in Applied Mathematics
This study presents a mathematical model to explore two-dimensional, time-dependent fluid flow towards a stagnation point over a Riga plate, under the influence of magnetohydrodynamics (MHD), activation energy, and a higher-order chemical reaction.

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 ...

UV‐Assisted Direct Ink Writing of Fully Bio‐Derived Photopolymer Composites With High Cellulose Loadings

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Fully bio‐based, cellulose‐reinforced inks are developed to 3D print structures via UV‐assisted extrusion. The inks flow easily during printing and solidify rapidly under light, enabling stable shapes and improved performance. Post‐print treatment allows tuning of strength and stiffness, demonstrating a sustainable route toward functional, plant‐based ...

The Divergent Effects of Nicotinamide Riboside and High‐Intensity Exercise Training on Skeletal Muscle Epigenetic Aging

Aging Cell, Volume 25, Issue 8, August 2026.
This study investigated the effects of nicotinamide riboside supplementation and high‐intensity interval training on skeletal muscle epigenetic aging. Our findings reveal that both interventions may modify epigenetic aging, with the muscle‐specific MEAT and DunedinPACE clocks showing the most responsiveness and links to mitochondrial abundance ...

Stagnation Flow of Eyring-Powell Hybrid Cu-Al2O3/Water Nanofluid Towards a Riga Plate with Newtonian Heating [PDF]

Journal of Applied and Computational Mechanics
The problem of convective heat transfers of Eyring-Powell conveying Copper (Cu) coupled with alumina (Al2O3) are employed as the combination of particles, along with water as the base fluid over a vertical Riga plate is numerically addressed.

Thermal analysis in Darcy-Forchheimer hybrid nanofluid through a Riga plate: An ANN optimization

Case Studies in Thermal Engineering
In the present study, a double-hybrid nanofluid's Darcy-Forchheimer flow behavior over a Riga plate with the presence of radiation and heat source impacts is examined. Two distinct nanoparticles as Silicon Carbide (SIC), and Graphite (C) with a base fluid of Ethylene glycol (C2H6O2) are taken into consideration. The model of Cattaneo-Christov heat flux
