Exempel på hur man kan använda BIOFOULING i en mening

• Barnacles are economically significant as biofouling on ships, where they cause hydrodynamic drag, reducing efficiency.
• The brig's composite hull was sheathed in copper to protect it from parasites and biofouling and it featured a pronounced tumblehome.
• Tube-side fouling for surface condensers falls into five main categories; particulate fouling like silt and sediment, biofouling like slime and biofilms, scaling and crystallization such as calcium carbonate, macrofouling which can include anything from zebra mussels that can grow on the tubesheet, to wood or other debris that blocks the tubing, and finally, corrosion products (discussed previously).
• Yokochi's current research focuses primarily on problems encompassing advanced functional materials and energy problems including the development of nanocomposite materials, the thermochemical production of hydrogen, the storage of renewable energy using flow batteries, and the development of methodology to avoid biofouling on devices deployed in the ocean.
• To combat parasites from biofouling in finfish aquaculture, treatment protocols such as cypermethrin, azamethiphos, and emamectin benzoate may be administered, but these have been found to have detrimental environmental effects, for example, in lobster operations.
• Because they would operate abroad, they required a significantly greater cruising range, and because dry dock facilities were limited in East Asia and the Pacific, their hulls were coppered to reduce biofouling and allow them to go longer between hull cleanings.
• The most effective natural biocide is 3,4-dihydroxybufa-20,22 dienolide, or bufalin (a steroid of toad poison from Bufo vulgaris), which is over 100 times more effective than TBT at preventing biofouling.
• MDCs are utilized in seawater desalination by primarily acting as a precursor treatment for electrodialysis (ED) due to the inefficiency in salinity removal due to biofouling and membrane scaling by the complex ion composition.
• Among her current projects is work on (1) temperature-sensitive membranes activated using superparamagnetic iron nanoparticles; (2) anti-biofouling membranes; (3) biofouling mechanisms; (4) nanoparticle fouling mechanisms; (5) bio-derived membranes; (6) green membrane fabrication and scale up; and (7) photocatalytic membranes.
