Biosurfactant production by Pseudomonas aeruginosa isolated from mining waste: From genomic analysis to development of a polymeric composite for removal of hexavalent chromium

open access: yesPolymer International, EarlyView.
Biosurfactant was produced by Pseudomonas aeruginosa using andiroba waste from Amazonia. A biosurfactant–alginate composite (Alg/BioS) was successfully synthesized via ionotropic gelation, and achieved up to 70% Cr6+ removal from water. Abstract Environmental contamination by heavy metals represents a significant challenge due to their persistence in ...

Synthesis and application of alginate@CuFe2O4 polymeric spheres in 17‐β‐estradiol adsorption processes in Amazonian rivers

open access: yesPolymer International, EarlyView.
Magnetic alginate beads, functionalized with copper ferrite, effectively remove 17‐β‐estradiol from Amazonian water, exhibiting optimized 238.65 μg g−1 capacity, fast 40 min kinetics, easy recovery, and successful remediation. Abstract The presence of endocrine‐disrupting compounds, such as 17‐β‐estradiol, in aquatic ecosystems poses a significant ...

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

open access: yesJournal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.

Polysulfide Immobilization and Sulfur Conversion Kinetics Promotion via a Tetrathiafulvalene–Crown Ether COF@Graphene Layer for High‐Rate Lithium–Sulfur Batteries

open access: yesSmall, EarlyView.
A polysulfide‐regulating covalent organic framework (TUS‐44) integrating tetrathiafulvalene and crown‐ether linkers forms an electron‐delocalized, ion‐coordinative network that synergistically mediates Li–S redox chemistry. When interfaced with graphene, the TUS‐44@G layer functions as a catalytic and chemisorptive interface, enabling efficient ...
