Preparation and Characterization of Sodium Alginate/Chitosan Composite Nanoparticles Loaded with Chondroitin Sulfate

open access: yesAdvances in Materials Science and Engineering, 2021
The chondroitin sulfate (CS)/sodium alginate (SA)/chitosan nanoparticles were prepared by electrostatic spraying technology. Laser particle size analyzer measurements indicated that the size of the particles is strongly affected by the weight ratio of ...

The reinforcing effect of oriented graphene on the interlaminar shear strength of carbon fabric/epoxy composites

open access: yesMaterials & Design, 2020
In this study, nano Fe3O4 functionalized graphene oxide (Fe3O4@GO) was employed to enhance the interlaminar shear strength (ILSS) of carbon fabric/epoxy (CF/EP) composites. The composite was fabricated via a vacuum-assisted resin transfer molding process

Wicking dynamics in yarns

open access: yesJournal of Colloid and Interface Science, 2022
The spontaneous imbibition of a liquid within porous media, known as wicking, can display uncommon features in textiles and yarns. Yarns exhibited step-wise wicking dynamics not captured by current models.Hypothesis: Wicking dynamics in yarns not only depend on inter-fiber pore filling, but are mainly determined by the pore-to-pore transition processes
