Six new compounds, omaezol, intricatriol, hachijojimallenes A and B, debromoaplysinal, and 11,12-dihydro-3-hydroxyretinol have been isolated from four collections of Laurencia sp. These structures were determined by MS and NMR analyses. Their antifouling activities were evaluated together with eight previously known compounds isolated from the same samples. In particular, omaezol and hachijojim...
The effects of fouling have only recently been subject to systematic scientific inquiry. Its seriousness, however, has been recognized from very ancient times. Although written records of the treatment of ship bottoms as early as the 5th century B. C.have been found, the search for an antifouling surfacè undoubtedly began with even earlier ships about which we have little information. Historica...
Marine biofouling has been an issue since antiquity whose solutions have a history of negative environmental impact. The development environmentally sustainable is paramount as society becoming more conscious anthropogenic impacts on the global ecosystem, particularly oceans. Herein we include brief overview common strategies in marine antifouling coatings terms their efficacy, durability, and ...
Contamination of biomedical devices in a biological medium, biofouling, is a major cause of infection and is entirely avoidable. This mini-review will coherently present the broad range of antifouling strategies, germicidal, preventive and cleaning using one or more of biological, chemical and physical techniques. These techniques will be discussed from the point of view of their ability to inh...
An experimental study has been made to compare the frictional resistance of several ship hull coatings in the unfouled, fouled, and cleaned conditions. Hydrodynamic tests were completed in a towing tank using a flat plate test fixture towed at a Reynolds number ~ReL! range of 2.8310 6 – 5.5310 based on the plate length and towing velocity. The results indicate little difference in frictional re...
