Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This study investigates the flow of a magnetized hybrid nanofluid over a permeable stretching surface. The mass and thermal transport within the system is regulated using the Cattaneo–Christov flux theory. The fluid is additionally subjected to thermophoresis, chemical reaction, Brownian motion, and activation energy effects.

Journal of Applied Polymer Science, EarlyView.Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Journal of Applied Polymer Science, EarlyView.Thermal black improves polyurethane foam structure and stability. It helps the foam rise smoothly while promoting the formation of smaller, more uniform cells. The foam keeps its strength and insulation performance while reducing shrinkage. Its clean production and easy processing make it a sustainable, cost‐effective option for high‐performance ...

Metalens‐Enabled Double‐Helix Point Spread Function for Multifunctional Imaging
Advanced Physics Research, EarlyView.A single metalens is employed to generate a double‐helix point spread function (DH‐PSF). At the design wavelength, the PSF rotation angle varies linearly with depth, while the lobe spacing follows an inverse dependence on axial position. At a fixed depth, the lobe spacing further exhibits a linear dependence on wavelength due to dispersion.

Production of 3D printed biomodels of the canine brain for veterinary neuroanatomy teaching
Anatomical Sciences Education, EarlyView.Abstract Teaching neuroanatomy presents multiple challenges to both students and teachers, as it is a subject with highly dense content that commonly causes the development of aversion by students, a phenomenon referred to as “neurophobia,” which has been documented in human and veterinary medicine students.

Business Strategy and the Environment, EarlyView.ABSTRACT Retired electric vehicle (EV) batteries can be repurposed to stationary storage batteries. While this circularity solution has attracted attention from entrepreneurs, falling battery prices, along with the longer lifetime of new batteries, high consumer expectations and limited governmental support challenge the approach.
