Large Eddy Simulation Of Tidal Turbines

open access: yes, 2017
Understanding of hydrodynamics involved in the ow around tidal turbines is essential to enhance their performance and resilience, as they are designed to operate in harsh marine environments. During their lifespan, they are subjected to high velocities with large levels of turbulence that demand their design to be greatly optimised.

A White Paper on Advancing Long‐Acting Therapeutics for Maternal and Pediatric Health by Bridging Gaps in Clinical Research, Access and Regulation

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
As use cases for long‐acting therapeutics expand across clinical indications, there is a critical need to ensure the inclusion of women who are pregnant or breastfeeding, infants and children—populations with a historical gap in the availability of interventions already approved for use in adults.

Enhancing hydrogen evolution reaction by harnessing bubble dynamics regulation: Principles, methods, and outlook

open access: yesDroplet, EarlyView.
Bubble dynamics pose critical bottlenecks to hydrogen evolution reaction efficiency, causing active site isolation, increased ohmic resistance, and concentration overpotential, especially at high current densities. This review comprehensively summarizes passive and active bubble manipulation strategies, elucidates their underlying principles, and ...

Large-eddy simulation of pyroclastic density currents

open access: yes, 2009
We investigate the dynamics of turbulent pyroclastic density currents (PDCs) by adopting a 3D, Eulerian-Eulerian multiphase flow model, in which solid particles are treated as a continuum and the grain-size distribution is simplified by assuming two ...

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Dimensional Engineering of Wet‐Spun MOF‐Based Woven Fabrics for Superior Electromagnetic Wave Absorption

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work fabricated MOF‐based woven absorbing fabrics with dimensional engineering via a wet spinning strategy. The absorbing fabrics achieve a reflection loss of −51.47 dB at 2.9 mm, with an effective absorption bandwidth reaching 3.54 GHz. The absorbing fabrics can be freely bent, stretched, and folded, with individual fibers exhibiting a break ...
