Measurements of the inherent optical properties of aqueous suspensions of microplastics

Limnology and Oceanography Letters
Libraries of inherent optical properties (IOPs) of microplastics are sparse, yet they are essential for the development of optical techniques to detect and quantify microplastics in the ocean.

New developments in point-particle simulation: insights from particle-resolved simulations and theory

, 2019
The Eulerian-Lagrangian point-particle method has become a leading paradigm in the study of dispersed particle-laden flows. This strategy simultaneously represents the non-continuum physics of the dispersed phase coupled to the continuum physics of the ...

Optimization of Flow Uniformity in Fixed-Bed Reactors Using Particle-Resolved Computational Fluid Dynamics and Response Surface Methodology

International Journal of Chemical Engineering
Fixed-bed reactors are widely employed in chemical processes because of their operational stability and high catalyst-loading capacity. However, their performance is often constrained by complex flow behavior within the packed bed.

Uniform Amorphization of Crystalline Silicon Surfaces Enabled by Deep Ultraviolet Femtosecond Laser Pulses

Advanced Engineering Materials, EarlyView.
Deep‐UV (258 nm) femtosecond pulses enable uniform amorphous silicon writing on Si(100)/(111) with a six‐fold larger fluence amorphization window than NIR methods. Optimized fluence and overlap yield 20–45 nm uniform and continuous amorphous layers. Microscopy shows sharp interfaces, and real‐time reflectivity reveals nanosecond melt–resolidification ...

Interface-resolved simulation of droplet–particle interaction dynamics in multi-particle collisions

Physics of Fluids
Understanding wet particle collisions involving droplets is essential for optimizing industrial processes. This study employs interface-resolved simulations combining the volume of fluid model, surface tension model, particle motion model, and overset grids to analyze particle–droplet interactions.

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Enhanced Ultrasound Transmission Through Aberration Layers Using Space‐Coiling Acoustic Metamaterials

Advanced Engineering Materials, EarlyView.
Enhancing ultrasound transmission through an aberration layer exhibiting mismatched impedance with the surrounding medium possesses great implications in imaging and treatment. In this study, we show that a space‐coiling acoustic metamaterial with judiciously tailored structural profile can help improve impedance matching.
