Diurnal Pulses in Tropical Cyclones as Convectively Coupled Gravity Waves

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract This study uses convection‐permitting simulations to examine the vertical extent, propagation, and nighttime preference of diurnal pulses (DPs) in tropical cyclones (TCs). DPs are outward‐moving rings of cooler brightness temperatures near the storm center and may indicate TC intensification.

Vortical Differential Scattering of Spatio‐Temporal Optical Vortex With Arbitrarily Oriented Orbital Angular Momentum by Chiral Spherical Particle

Nanophotonics, Volume 15, Issue 15, 13 August 2026.
The vortical differential scattering of spatiotemporal optical vortices by chiral particles is investigated. It is revealed that a longitudinal orbital angular momentum component is essential for inducing vortical dichroism, whereas a purely transverse OAM yields no chiral response.

Engineering Layered Magnetic Hydrogels for Cell Placement via Shear and Magnetic Field‐Induced Assembly

Advanced Materials, Volume 38, Issue 44, 7 August 2026.
Magnetic particles are organized into layered architectures by combining shear flow and magnetic fields, with the resulting structures governed by appropriate Mason numbers. The programmed assemblies provide spatial guidance for cell placement, linking field‐controlled self‐assembly, flow‐induced structuring and biological organization.

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing

Advanced Science, Volume 13, Issue 45, 13 August 2026.
Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

Transient Conjugate MHD Flow With Variable Thermal Conductivity: A CFD to ANN Study

Engineering Reports, Volume 8, Issue 8, August 2026.
A star‐shaped obstacle inside a hexagonal cavity alters fluid flow and heat transfer under magnetic fields. Simulations and ANN predictions reveal that magnetic strength and material properties control cooling efficiency, supporting smarter designs for real‐time thermal management.
