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 ...

Representações e novas tecnologias

Revista Pedagógica, 2018
Esta exposição centra a atenção sobre a dificuldade que o paradigma moderno tem de explicar a tecnologia e a sociedade e tenta mostrar como a relação e a mistura entre as duas as constitui, como funciona e como pode ser compreendida. A representação moderna vê o mundo composto por elementos independentes, exteriores uns aos outros, constituindo uma ...

Muscle fatigue in patients with severe long COVID: A 2‐year follow‐up study

PM&R, EarlyView.
Abstract Background Fatigue is recognized as one of the most persistent and debilitating symptoms of long COVID, affecting both functionality and quality of life. However, its long‐term effects, especially beyond the first year after infection, remain poorly understood.

Mg2+ Ions as Interfacial Charge Bridges for Enhanced Photocatalytic Hydrogen Evolution in Poly(Heptazine Imide)

Small, EarlyView.
Mg2+ confined within poly(heptazine imide) acts as a heterogenized interfacial charge bridge capable to couple synergistically the semiconductor with Pt co‐catalysts, thus enhancing hydrogen evolution. Through water polarization and hydroxide stabilization, a dynamic Mg2+‐OHδ−‐Hδ+‐Pt motif facilitates proton transfer and overcomes interfacial electron ...

Local Ecological Knowledge Reveals the Distribution of Cryptic Nocturnal Wildlife 局域生态知识揭示隐秘夜行野生动物的分布

Wildlife Letters, EarlyView.
Many nocturnal animals are difficult to study because they are rarely seen, including nocturnal primates, galagos and pottos, in West Africa. Working with over 600 people in 52 villages in southern Guinea‐Bissau, we found that communities frequently recognized galagos by their red eyeshine and distinctive calls, while pottos were not known.

Room‐temperature crystal structure of a metal‐dependent W‐formate dehydrogenase by serial synchrotron crystallography

Acta Crystallographica Section D, EarlyView.
We report a room‐temperature serial synchrotron X‐ray crystallographic structural analysis of Nitratidesulfovibrio vulgaris formate dehydrogenase AB, an enzyme that reduces CO2 to formate.Metal‐dependent formate dehydrogenases (Fdhs) are a promising research target in efforts to mitigate climate change by developing active, efficient, selective and ...

Bat community assembly in the ecotone of two neotropical biodiversity hotspots is determined by environmental filtering rather than historical factors

Journal of Animal Ecology, EarlyView.
We demonstrate that environmental filtering is the primary mechanism shaping bat communities across the Cerrado–Atlantic Forest ecotone. By integrating phylogenetic diversity, environmental gradients, and coevolutionary assembly models, our study provides new insights into the processes maintaining biodiversity in a globally important transition zone ...

High School GPA and Exam Scores: Does Their Relevance for First‐Year Academic Performance Vary With Program Selectivity?

Bulletin of Economic Research, EarlyView.
ABSTRACT This paper examines student admissions to higher education based on past performance, focusing on two measures: high school GPA and national exam scores. GPA is teacher‐assigned and based on repeated assessments, while these exams are externally graded, one‐off standardized tests. Using a nationwide dataset, we investigate how the relevance of
