Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

open access: yesGeological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Metagenomics and digital cell modeling facilitate targeted high‐throughput sorting of anaerobic hydrogen‐producing microorganisms

open access: yesiMeta, EarlyView.
This study proposes a novel strategy that prioritizes functional recognition, followed by targeted high‐throughput sorting, to enable the comprehensive, rapid, and efficient acquisition of target microorganisms. Using metagenomic sequencing and binning analysis, we identified 215 potential anaerobic hydrogen‐producing strains from 12 large‐scale biogas

Increase in CH4 Emissions in a Pantanal Wetland Lagoon Due to Extreme Drought and Sediment Exposure

open access: yesInternational Review of Hydrobiology, EarlyView.
ABSTRACT The Pantanal, one of the largest wetlands on Earth, stores substantial carbon in its diverse ecosystems but faces increasing threats, such as fires, poor soil management, deforestation, and climate change impacts that may elevate CH₄ emissions.

NITRIC OXIDE (NO), CITRULLINE - NO CYCLE ENZYMES, GLUTAMINE SYNTHETASE AND OXIDATIVE STRESS IN ANOXIA (HYPOBARIC HYPOXIA) AND REPERFUSION IN RAT BRAIN

open access: yesInternational Journal of Medical Sciences, 2010
Nitric oxide is postulated to be involved in the pathophysiology of neurological disorders due to hypoxia/ anoxia in brain due to increased release of glutamate and activation of N-methyl-D-aspartate receptors.

Lake–Groundwater Biogeochemical Interactions in a River‐Delimited System: The Groundwater and Lakes Urban Observatory (GLUO)

open access: yesInternational Review of Hydrobiology, EarlyView.
ABSTRACT Preservation of urban aquatic ecosystems is of primary importance for human well‐being, biodiversity protection and the future of society. Lake–groundwater–river interactions within urban floodplains harbour intrinsic fragility, yet remain largely understudied.

Magnetic nanoparticles‐decorated zeolite thin film derived from coal fly ash: Application to detoxification of para‐nitrophenol

open access: yesJournal of the Chinese Chemical Society, EarlyView.
Magnetic zeolite films: Application for the detoxification of para‐nitrophenol. Abstract Fly ash, an industrial by‐product generated from coal combustion, poses significant environmental and health hazards. However, its remarkable adsorption behavior for various toxic pollutants can be further enhanced through physical and chemical modifications ...
