Sustainable Flame‐Retardant Poly Lactic Acid Biocomposites Reinforced with Polyphosphate‐Enriched Microalgae: Unlocking the Potential of Hyper‐Compensation

open access: yesAdvanced Sustainable Systems, EarlyView.
This study explores microalgae cultivation for wastewater treatment and enhancement of poly lactic acid (PLA)‐based biocomposites. It achieves up to 99.9% nutrient removal, increases biomass productivity by 322%, and demonstrates a triphasic luxury phosphorus uptake system. Incorporation into PLA improves fire‐retardant properties, suggesting potential

Bifunctional WO3 Photoelectrodes Decorated by Inkjet Printing for Solar Supercapacitors

open access: yesAdvanced Sustainable Systems, EarlyView.
WO3 bifunctional photoelectrodes, produced by screen printing and then superficially decorated by inkjet printing, are successfully applied to prepare solar supercapacitors. Under illumination, the areal capacitance is enhanced thanks to the positive contribution of the photogenerated charges and the higher exposed area; its value becomes even more ...
