As with inorganic colloids, most research on biocolloid mobility has been done on saturated transport, with little known about transport in unsaturated soils.
Often the colloidal particles themselves are contaminants of concern, such as colloid-sized pathogenic bacteria and viruses (sometimes referred to as biocolloids) or aggregations of toxic elements.
Milk is a biocolloid
. The synovial fluids that lubricate joints in our body are colloidal in nature.
Director of the Centre for Applied Colloid and BioColloid
Science at Swinburne University, Dr Greg Lonergan, says composting cycles and earthworms are used to test the CRC products.
Flow of suspensions and colloids in porous media with particle retention by matrix is also important for filtering of water and industrial liquid or gas fluid streams [8-10], enhanced bioremediation [11, 12], particle accumulation in the streambed sediments , propagation of biocolloids
(bacteria viruses and protozoan parasites) in aquifers, surface water and wastewater treatment, and so forth [14-20].
humic and fulvic acids, polysaccharides, etc.) and biocolloids
iron (Fe), aluminium (Al), manganese (Mn), or silicon (Si) hydro-oxides, carbonates, phosphates), and biocolloids
including viruses, bacteria, and protozoans (Buffte et al.
They cover phenomena at the micro, nano, and atto-scales, and techniques, theory, and supporting data, and detail recent concepts in the physics and chemistry of interfaces of rigid and deformable particles in homo- and heteroaggregate dispersed systems like emulsions, dispersoids, suspensions, nanopowders, foams, fluosols, polymer membranes, biocolloids
, and plasmas, and the hydrodynamic, electrodynamic, and thermodynamic instabilities that occur at interfaces.
In this work, we focus only on inorganic colloids, even though biocolloids
and organic matter may deserve equal attention.
Living organisms are complex heterogeneous systems in which biocolloids
and physicochemical reactions play the leading role.
From this, it can be extrapolated that a daily loss of iron, as red dust and yellow biocolloids, of between 0.13 and 0.20 tons per day could be occurring from the wreck.
On both the 1996 and 1 998 expeditions, there were periods when the "sea snow", a mixture of biocolloids and zooplankton, was so intense that it resembled a blizzard on the prairies.
