Life-Cycle Perspectives on Aquatic Ecotoxicity of Common Ionic Liquids

open access: yes, 2016
This study compares the aquatic ecotoxicity impacts of production- and use-phase release of five common ionic liquids (ILs). Integrating toxicity data, physical properties, and fate and transport parameters with the USEtox model, we report, for the first

Carbon‐Negative Upcycling of Sewage Sludge into Superiorly Stable Gel Via Liquid‐Phase Utilization Strategy for Water‐Remediation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work developed a low‐temperature sludge hydrothermal coupled with gel crosslinking strategy which could upgrade the waste liquid generated from sewage sludge hydrothermal treatment into the hydrothermal‐liquid‐gel. The inventive hydrothermal‐liquid‐gel exhibited the enhanced pollutant removal capability, high synthetic stability, and superior ...

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.
