Mercury (Hg) is a global and top priority contaminant, toxic at low concentrations. Although it
has been progressively eliminated from processes, this metal continues to circulate in the
atmosphere, soil, and water. In this work, the Response Surface Methodology (RSM)
combined with a Box-Behnken Design (3 factors-3 levels) was used to optimize key
operational conditions that influence the removal and uptake of Hg by living macroalga Ulva
sp. in a complex mixture containing several elements used in industry (potentially toxic …

Fibers are extensively used as a fluid additive in the oil and gas industry to improve hole-
cleaning performance, control fluid filtration loss, and enhance hydraulic fracturing
effectiveness. Generally, a small amount of fiber is dispersed in the base fluid to achieve the
desired results without increasing the viscosity of the base fluid. Nevertheless, sustaining a
uniform fiber dispersion can be challenging under wellbore conditions, which is essential for
fibers' functionality. Consequently, a better understanding of fiber suspension or stability in …
