Superparamagnetic iron oxide nanoparticles (NPs) are used in a rapidly expanding number of research and practical applications in the biomedical field, including magnetic cell labeling separation and tracking, for therapeutic purposes in hyperthermia and drug delivery, and for diagnostic purposes, e.g., as contrast agents for magnetic resonance imaging. These applications require good NP stabil...

Aquatic toxicity considerations are part of the net environmental benefit analysis and approval decision process on the use of dispersants in the event of an offshore oil spill. Substantial information is available on the acute toxicity of physically and chemically dispersed oil to a diverse subset of aquatic species generated under controlled laboratory conditions. However, most information ha...

Oil dispersants, the tool of choice for treating oil spills in tropical marine environments, is potentially harmful to marine life, including reef corals. In a previous study, we found that dispersed oil and oil dispersants are harmful to soft and hard coral species at early life stages. In this broader study, we employed a "nubbin assay" on more than 10 000 coral fragments to evaluate the shor...

Increasingly frequent petroleum contamination in water bodies continues to threaten our ecosystem, which lacks efficient and safe remediation tactics both on macro and nanoscales. Current nanomaterial and dispersant remediation methods neglect to investigate their adverse environmental and biological impact, which can lead to a synergistic chemical imbalance. In response to this rising threat, ...

A novel dispersive liquid–liquid microextraction method based on the solidification of a floating organic droplet was proposed to pre-concentrate 16 polycyclic aromatic hydrocarbons (PAHs) from water samples prior their determination using gas chromatography–mass spectrometry, in which effect hydrophilic deep eutectic solvent (DES) used as dispersant investigated. The main extraction parameters...

Currently, oil spill pollution is one of the major environmental concerns for sea cucumber (Apostichopus japonicus) aquaculture. During spills, spraying chemical dispersants generally considered an efficient response. However, impact dispersant deployment during spills on cucumbers still less known. In this study, we treated with physically and chemically (by GM-2 dispersant) dispersed Oman cru...

Carbon dioxide capture and storage is the primary way to reduce greenhouse gas emissions on a large scale. critical link of this technology, in which achieve long-term problem be considered. The elastic anti-corrosion cement slurry key for successful carbon dioxide. In order develop storage, influence resin with both properties performance was investigated. dispersant, retarder, filtrate reduce...
