After the April 2010 explosion on the Deepwater Horizon oil rig, and subsequent release of millions of barrels of oil, two Corexit oil dispersant formulations were used in unprecedented quantities both on the surface and sub-surface of the Gulf of Mexico. Although the dispersant formulations contain four classes of surfactants, current studies to date focus on the anionic surfactant, bis-(2-eth...

BACKGROUND Polylactic acid (PLA) is considered to be a sustainable alternative to petroleum-based polymers for many applications. Using cellulose fiber to reinforce PLA is of great interest recently due to its complete biodegradability and potential improvement of the mechanical performance. However, the dispersion of hydrophilic cellulose fibers in the hydrophobic polymer matrix is usually poo...

A novel electrocatalyst of layered MoS2 supported on reduced graphene oxide (RGO) decorated with nano-sized tungsten carbide (WC) shows an enhanced catalytic performance in the hydrogen evolution reaction, which could be attributed to the presence of a conductive and electrocatalytically-active nano-WC dispersant and the positive synergistic effect between nano-WC/RGO and layered MoS2.

In this paper, the preparation process of low viscosity light curing silicon oxide ceramic slurry and properties sintered samples were studied. By studying effects type concentration dispersant solid content powder on stability slurry, with viscosity, high good was prepared. The ceramics verified by compressive strength, shrinkage test SEM observation. results show that stearic acid as dispersa...

Resource extraction from the ocean comes with ecosystem-wide risks, including threats to its biota such as habitat forming corals that support elevated biomass and biodiversity. Despite catastrophic incidents like Deepwater Horizon oil spill (DWHOS) disaster occurred in 2010, offshore gas drilling continues occur around world. Previous work investigating toxicity of chemical dispersant used an ...

In this study, the physicochemical characteristics of crude oil, dispersant and oil-dispersant test systems their toxicities on representative marine organisms in a simulated ecosystem was assessed. Mechanically dispersed oil-in-water system (MDO) its water accommodated fraction (WAF) alone, combination with third generation (D) (Ecobest®), which gave rise to chemically (CDO) (CEWAF), as well r...
