Protocol for the Preparation of Polyphenols‐Polysaccharide Nanoparticles

open access: yesFood Chemistry International, EarlyView.
ABSTRACT Polyphenols, natural compounds abundantly distributed in plants, possess potent antioxidant and anti‐inflammatory activities and hold promising potential in cardiovascular protection and the management of metabolic disorders. Nevertheless, their intrinsic instability and low bioavailability severely constrain their practical and large‐scale ...

Numerical study of wave transmission over double submerged breakwaters using non-hydrostatic wave model

open access: yesOceanologia, 2015
In the present work, a non-hydrostatic wave model SWASH (an acronym of Simulating WAves till SHore) is used to simulate the wave transmission over double trapezoidal submerged breakwaters.

The Dependence of Properties on Structural Features in Macro/Micro Levels for PBF‐LB Fabricated Porous NiTi Alloy

open access: yesRare Metals, EarlyView.
ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...

Numerical study on the influence of infiltration on swash hydrodynamics and sediment transport in the swash zone [PDF]

open access: yes, 2017
Infiltration and exfiltration processes have a significant influence on the hydrodynamics of the swash zone. Such processes need to be taken into account in the modelling of cross-shore sediment transport and the prediction of beach profile evolution ...

Twin‐Wire In Situ Additive Manufacturing of NiTiNb Eutectic Alloys: Eliminating Unmelted Nb Particles and Tailored Superelasticity

open access: yesRare Metals, EarlyView.
ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...

Study on mixed lubrication characteristics of piston/cylinder interface of variable length

open access: yesAIP Advances, 2019
Aiming at the lubrication problem of piston/cylinder interface of variable length, a two-dimensional mixed lubrication model was established. This model considers the adaptive eccentricity and the force balance of the piston.
