Iron (Fe) is mostly complexed with the organic ligands or colloids that are very abundant in natural seawater. In this study, natural colloids were isolated by ultrafiltration and radiolabeled with 59 ...

Amid the balance of attractive decoration size, colloid size, ionic strength and water velocity, the new theory shows how colloids can stick. By varying colloid size, ionic strength and water velocity ...

Particles are of a colloidal size if their size falls in the range of 1 to 1000nm. A colloid is system whereby colloidal particles are suspended in a continuous medium. They are stable and do not ...

Over the past few years, our research group has been investigating some of the geochemical controls on the mobilization and transport of colloids in saturated porous media. Colloids have been ...

In the field of nanotechnology, where properties and functionality of nanostructures critically depend on their dimensions, measuring size differences of the order of nanometers or even angstroms is ...

When bacteria and viruses get into well water and make people sick, often the contamination comes after heavy rain or flooding. In 2000, more than 2,300 people in Walkerton, Ontario, got sick when, ...
