A total of 20 biogenic carboxylic acids, which contain one to three negatively charged -COOgroup(s), were investigated as dispersion additives in the processing of ceramic particles. Only carboxylic acids containing one or more hydroxyl groups were able to disperse ct-A120 3 particles in aqueous suspensions. Detailed studies of two carboxylic acids, citric acid and tricarballylic acid were unde...
During the Deepwater Horizon incident, crude oil flowed into the Gulf of Mexico from 1522 m underwater. In an effort to prevent the oil from rising to the surface, synthetic dispersants were applied at the wellhead. However, uncertainties in the formation of oil droplets and difficulties in measuring their size in the water column, complicated further assessment of the potential effect of the d...
Following the Deepwater Horizon blowout, oil, degraded oil mixed with dispersants, and management responses to spill affected a variety of Gulf Mexico organisms. This review provides examples various documented impacts, common patterns, trends across organisms and/or their environments, discusses future implications as well directions for research. Organism effects are generally characterized l...
