Sprayable Polyolefin Sorbents Enabled by Bio‐Solvents for Large‐Scale Oil and Chemical Spill Recovery

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A sprayable POE‐based sorbent formulated with a green solvent blend of α‐pinene, D‐limonene, and p‐cymene enables rapid in situ film formation via solvent evaporation, allowing efficient pollutant capture. The system exhibits high oil uptake (37.3 g g−1) and effectively removes up to 60 mL of VLSFO under simulated marine spill conditions.

Chemically Modular, Nonfluorinated Polymer Adsorbents for Capturing Per‐ and Polyfluoroalkyl Substances (PFAS)

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Nonfluorinated polymer networks for PFAS adsorption are synthesized using active ester click chemistry. Incorporating Lewis base ligands along with hydrophilic and hydrophobic co‐monomers leads to high PFOA binding efficiency. Ligand basicity and pH are found to play an important role in PFOA sorption.

Assessment of trace metals in Amazonian fish exposed to untreated urban sewage: high chromium concentrations in fish tissues

open access: yesRevista Ambiente & Água, 2015
The aim of this study was to evaluate the quality of fish meat in relation to inorganic contaminants (Zn, Pb, Cu, Cr, Ni and Hg), following the Brazilian Health Surveillance Agency (ANVISA) standards in five Amazonian fish exposed to untreated urban ...

Learning Networks Drive Environmental Innovation: Evidence From Fourth‐Stage Purification Diffusion

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Contaminants of emerging concern, including pharmaceuticals and industrial chemicals, threaten water quality globally. In the European Union (EU), until the adoption of the revised Urban Wastewater Treatment Directive in 2024, a regulatory gap had left the member states and the municipalities in them without binding removal standards ...

Per- and polyfluoroalkyl substances (PFAS) in the cryosphere – occurrence, organismic accumulation, ecotoxicological impacts, transformation, and management strategies

open access: yesFrontiers in Environmental Science
The cryosphere faces increasing threats from anthropogenic pollutants, including per- and polyfluoroalkyl substances (PFAS), a class of synthetic chemicals produced in significant quantities and released into the environment for over seven decades.

Total Synthesis of Sacrolide A and Cytotoxic Evaluation

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Isolated from the edible cyanobacterium Aphanothece sacrum, sacrolide A is a highly potent antimicrobial and cytotoxic metabolite. Its total synthesis via a convergent strategy enabled accurate assessment of its effects on liver and colon cells, offering new insights into its bioactivity and potential health risks.
