Antioxidant Response and Oxidative Stress in the Respiratory Tree of Sea Cucumber (Apostichopus japonicus) Following Exposure to Crude Oil and Chemical Dispersant

Journal of Marine Science and Engineering, 2020
Sea cucumber (Apostichopus japonicus) is mainly cultured in the coastal zone, where it is easily threatened by accidental oil spills. Chemical dispersant is one of the efficient oil spill responses for mitigating the overall environmental damage of oil ...

C‐Terminal Nucleobase Modification Amplifies Peptide‐Mediated Liposome Fusion

Chemistry – A European Journal, EarlyView.
Let's come together right now. Cationic peptides are known to promote aggregation of negatively charged liposomes through electrostatic interaction. The process is reversible: once neutrality is achieved, liposomes disaggregate. Here, we demonstrate that end‐capping peptides with nucleobases turns the process into irreversible fusion.

EWOD Sensor for Rapid Quantification of Marine Dispersants in Oil Spill Management

Journal of Sensor and Actuator Networks
In this study, we introduce a novel Electrowetting-on-Dielectric (EWOD) sensor designed to quantify marine dispersants at the spill point. The sensor quantifies changes in the surface tension of liquid droplets at varying dispersant concentrations ...

Synergistic Modulation of Conductivity and Oxidation Stability in SiHfBCN Ceramics via UV‐Assisted Structural Evolution

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A quinary UV‐curable SiHfBCN ceramic photoresist with high ceramic yield enhanced is developed through sequential molecular design for high‐temperature sensing coatings. The elevated interconnected conductive network induced by chemically bonded carboxylated MWCNTs enables the pyrolyzed ceramics' enhanced conductivity and excellent oxidation stability.

Chemical dispersants used in the Gulf of Mexico oil crisis are cytotoxic and genotoxic to sperm whale skin cells

, 2014
The 2010 Deepwater Horizon oil rig explosion in the Gulf of Mexico drew attention to the need for toxicological studies of chemical dispersants. We are still learning the effects these spills had on wildlife.

Biodegradation of Alkali-O2 Oxidized Lignins Used as Dispersants

BioResources, 2022
Large quantities of lignin are produced as by-streams via chemical pulping and emerging biorefinery processes. These lignins are typically water-insoluble; however, they can be converted into a water-soluble form by chemical modifications.
