Mechanical, Thermal, and Microstructural Evaluation of Bio‐Based Polyurethane Composites Reinforced With Woven Jute and Flax

Polymer Composites, EarlyView.
Graphical overview of the manufacturing and characterization of bio‐based polyurethane composites reinforced with woven jute and flax fibers produced by the VARTM process. Mechanical, thermal, and microstructural analyses reveal differences in stiffness, thermal stability, and interfacial behavior between the natural fiber composites.

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

Polymer 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

Polymer 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 ...

Assessing the evolutionary distinctiveness of a highly threatened plant group: The urgency to preserve a unique lineage of evolution in Brazil

PLANTS, PEOPLE, PLANET, EarlyView.
Brazil's diverse flora is under several threats, with many unique lineages facing extinction, particularly in biodiverse regions like the Cerrado and campo rupestre. This study sheds light on the conservation needs of Cambessedesia (Melastomataceae), an endemic genus with 95% of its species endangered, using an approach to rank and prioritise species ...

Balancing tracks and trees: Assessing railroad impact on Brazilian biodiversity

PLANTS, PEOPLE, PLANET, EarlyView.
The Brazilian West–East Integration Railway (FIOL) aims to boost the national economy by improving commodity transport; however, it crosses three of Brazil's most biodiverse and fragile regions: the Caatinga, Cerrado and Atlantic Forest. Using digitised plant records and land‐use analyses, our study reveals significant vegetation loss within the ...

Effects of Glyphosate on the Planktonic Microbiota: An Experimental Approach

Environmental Toxicology, EarlyView.
ABSTRACT Glyphosate is one of the most widely used herbicides in the world, including in Brazil, and its dispersion through habitats and surface waters can impact entire aquatic ecosystems. However, experimental studies evaluating the effects of pesticides on whole planktonic communities, considering attributes such as richness, density and composition—
