Promoting microalgal biofilm formation by crushed oyster shell-hydroxyapatite layer on micropatterned aluminum coating for heavy metal ions removal.

Microalgal biomass has shown inspiring potential for the heavy metal removal from wastewater, and forming microalgal biofilm is one of the sustainable methods for the microalgal biomass production. Here we report the formation of microalgal biofilm by accelerated colonization of typical algae Chlorella on thermal sprayed aluminum (Al) coatings with biologically modified surfaces. Micro-patterning surface treatment of the Al coatings promotes the attachment of Chlorella from 6.

A pH-Responsive Polycaprolactone-Copper Peroxide Composite Coating Fabricated via Suspension Flame Spraying for Antimicrobial Applications.

In this study, a pH-responsive polycaprolactone (PCL)-copper peroxide (CuO) composite antibacterial coating was developed by suspension flame spraying. The successful synthesis of CuO nanoparticles and fabrication of the PCL-CuO composite coatings were confirmed by microstructural and chemical analysis. The composite coatings were structurally homogeneous, with the chemical properties of PCL well maintained.
