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

ENERGY &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.

The Deep-Sea Microbial Community from the Amazonian Basin Associated with Oil Degradation

Frontiers in Microbiology, 2017
One consequence of oil production is the possibility of unplanned accidental oil spills; therefore, it is important to evaluate the potential of indigenous microorganisms (both prokaryotes and eukaryotes) from different oceanic basins to degrade oil. The

Optimizing Fabrication of Plasma‐Driven CuO Shell Over Porous Al2O3 Substrate to Meet Coating Issues

Journal of the Chinese Chemical Society, EarlyView.
In situ Cu2O‐to‐CuO transformation during plasma electrolytic oxidation of aluminum alloys. ABSTRACT A plasma‐driven in situ conversion strategy was developed in which Cu2O nanoparticles introduced into an alkaline phosphate–hydroxide electrolyte undergo oxidative transformation to CuO within plasma micro‐discharge channels during plasma electrolytic ...

Performance evaluation of acrylic additives and process parameters in freeze granulation for advanced alumina powder processing

European Journal of Materials
Freeze granulation is an effective method for producing homogeneous and spherical ceramic granules, although its efficiency depends strongly on the formulation and processing conditions of the initial suspension.

Formulation of a Commercial Biosurfactant for Application as a Dispersant of Petroleum and By-products Spilled in Oceans

Frontiers in Microbiology, 2016
Oil spills in oceans cause irreparable damage to marine life and harm the coastal populations of affected areas. It is therefore fundamental to develop treatment strategies for such spills. Currently, chemical dispersants have been used during oil spills,

A Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs

Journal of Surfactants and Detergents, EarlyView.
The Green Amphoteric Surfactant Derived From Rapeseed Oil for Enhanced Oil Recovery From Carbonate Acidic Oil Reservoirs. ABSTRACT Surfactants with both positive and negative functional groups (amphoteric or zwitterionic) are particularly advantageous in acidic oil reservoirs because they remain stable under harsh chemical conditions, tolerate acidic ...

Rheology of Titania Pigment Slurry

Applied Rheology, 2012
The influence of polymeric dispersants containing different functional groups on the suspension behaviour of titania pigment slurry was investigated. The dispersants chosen were polyacrylic acid and modified polyacrylamides including homo and copolymers ...

Image_1_Chemical Dispersant Enhances Microbial Exopolymer (EPS) Production and Formation of Marine Oil/Dispersant Snow in Surface Waters of the Subarctic Northeast Atlantic.PNG

, 2019
A notable feature of the Deepwater Horizon oil spill was the unprecedented formation of marine oil snow (MOS) that was observed in large quantities floating on the sea surface and that subsequently sedimented to the seafloor.

Laboratory Evaluation Of Chemical Oil Dispersants [PDF]

International Oil Spill Conference Proceedings, 1969
Abstract This paper describes some of the methods which can be used to evaluate chemical oil dispersants in order to obtain some preliminary data related to their effectiveness as dispersants and problems that may result from their use. Most of the techniques are quite simple and can be done fairly rapidly in the laboratory.
