Advances in Ultraviolet Technology for Food Processing: Engineering, Matrix‐Driven Design, and Future Directions

open access: yesJournal of Food Process Engineering, Volume 49, Issue 10, October 2026.
Advances in ultraviolet technology for food processing. In this review, we present the main scientific principles and technical advances to broadly scale UV irradiation for food processing, considering synergies and a matrix‐driven design approach for validation studies.

A New Paradigm for Understanding the Rheology and Processability of Poly(p‐Phenylene Terephthalamide) Liquid‐Crystalline Solutions

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 34, September 10, 2026.
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

Hierarchical Assembly as a Design Principle: Structure–Property Relationships Linking Biological Architectures to Functional Aggregate Materials

open access: yesAggregate, Volume 7, Issue 9, September 2026.
Biological function arises from aggregates rather than from molecules. Comparing biomimetic systems on a common basis reveals three transferable design rules governing hierarchical assembly, interfacial gradients, and stimulus‐coupled anisotropy, and identifies self‐healing and single‐step multiscale integration as properties that do not transfer to ...

A Robust Control Approach to Understanding Nonlinear Mechanisms in Shear Flow Turbulence [PDF]

open access: yes, 2010
A robust control framework is used to investigate a streamwise constant projection of the Navier Stokes equations for plane Couette flow. Study of this streamwise constant model is motivated by both numerical and experimental observations that suggest ...

NUMERICAL EXPLORATION OF VISCOUS FLOW REGIMES: INSIGHTS FROM POISEUILLE, COUETTE AND TAYLOR-COUETTE FLOWS [PDF]

open access: yesProceedings on Engineering Sciences
We present a numerical study for Poiseuille and Couette as well as Taylor- Couette swirling flows. The governing equations of momentum and energy are transformed into coupled and nonlinear ordinary differential equations using similarity transformation ...

Thermal and Bioconvective Modeling and Analysis of Unsteady Cu‐Water Nanofluid Flow through Porous Media with Gyrotactic Microorganisms

open access: yesEngineering Reports, Volume 8, Issue 9, September 2026.
The current study investigated unsteady boundary layer flow of a Cu/H2O$$ \mathrm{Cu}/{\mathrm{H}}_2\mathrm{O} $$ nanofluid over an expanding sheet embedded in a Darcy porous medium, containing gyrotactic microorganisms. The model includes heat source effects, unsteadiness, buoyancy, slip conditions, and nanoparticle radius.

Parametric Study of Turbulent Couette Flow over Wavy Surfaces Using RANS Simulation: Effects of Aspect-Ratio, Wave-Slope and Reynolds Number

open access: yesFluids, 2020
A turbulent Couette flow over a wavy surface is subject to a detailed parametric study in which three parameters—Aspect Ratio, Wave Slope and Reynolds number—are independently varied over an order of magnitude to investigate their influence on the flow ...

Local Ecological Knowledge Reveals the Distribution of Cryptic Nocturnal Wildlife 局域生态知识揭示隐秘夜行野生动物的分布

open access: yesWildlife Letters, Volume 4, Issue 3, Page 118-130, September 2026.
Many nocturnal animals are difficult to study because they are rarely seen, including nocturnal primates, galagos and pottos, in West Africa. Working with over 600 people in 52 villages in southern Guinea‐Bissau, we found that communities frequently recognized galagos by their red eyeshine and distinctive calls, while pottos were not known.

Couette flow of hot viscous gas

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2020
A new exact solution is found for the equations of motion of a viscous gas for a stationary shear flow of hot (800–1500 K) gas between two parallel plates moving at different speeds (an analog of the incompressible Couette flow).
