Avaliação do potencial de processos oxidativos avançados para remediação de águas contaminadas com geosmina e 2-MIB Evaluation of advanced oxidation processes for remediation of contamined water with geosmin and 2-MIB

Química Nova, 2008
In this work, the efficiency of some homogeneous advanced oxidation processes (UVC/H2O2, Fe2+/H2O2, UVC/Fe2+/H2O2, UVA/Fe2+/H2O2, solar/Fe2+/H2O2) was investigated toward the degradation of geosmin and 2-methylisoborneol (2-MIB).

Unexpected transformation of dissolved phenols to toxic dicarbonyls by hydroxyl radicals and UV light. [PDF]

, 2018
Water treatment systems frequently use strong oxidants or UV light to degrade chemicals that pose human health risks. Unfortunately, these treatments can result in the unintended transformation of organic contaminants into toxic products.

Potential of Advanced Oxidation as Pretreatment for Microplastics Biodegradation

Separations, 2023
In the last two decades, microplastics (MP) have been identified as an emerging environmental pollutant. Due to their small size, MP particles may easily enter the food chain, where they can have adverse effects on organisms and the environment in ...

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Nanoconfinement in advanced oxidation processes

Critical Reviews in Environmental Science and Technology, 2022
Advanced oxidation processes (AOPs) based on the generation of reactive radicals are widely accepted to be effective technologies for mineralizing refractory organic contaminants or pretreating bio-recalcitrant compounds. The efficiencies of AOPs suffer from the low availability of ultrashort lifetime radicals due to their rapid self-quenching, mass ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
