However, this review suggests that addition of macro size organic particles and inorganic nanoparticles can enhance rheological performance, reduce filtrate loss volume and improve shale inhibition characteristics of environmental friendly water-based mud (WBM).
This nanoscale size generally confers larger surface areas to nanoparticles (NPs) compared with macro-sized particles [4].
To generate the macroporosity, three straightforward and versatile strategies were implemented through the use of sodium chloride (NaCl) macro-sized particles.
There is evidence that fluidization characteristics of nano-sized particles may be analysed by analogies to those of macro-sized particles.
Analysis shows that fluidization characteristics of nano-sized particles may be bridged to those of macro-sized particles through particle aggregation.
The aim of this paper is to look at whether the mechanism resulting in cohesive behaviour for macro-sized particles may be extended to nano-sized particles.
Fluidization characteristics of macro-sized particles, from several tens of microns to several millimetres, are well described by the Geldart [1973. Types of gas fluidization, Powder Technology 7, 285] classification.
Because of their minute size and innovative surface coatings, nanoparticles may be able to pervade very small spaces in the subsurface and remain suspended in groundwater, allowing the particles to travel farther than larger, macro-sized particles and achieve wider distribution.
Potential solutions come in both micro and macro sizes.
The step-wise breakdown of macro- and micro-aggregates with concurrent liberation of micron- to submicron-size particles upon the increased levels of dispersion, therefore, represents clear evidence of aggregate hierarchy on this soil type.
Several polymer types (PE, PP, PA, bio polymers) in different sizes (macro and micro particles) and different qualities (new, recycling, plastic marine litter) were measured in transflection mode with FTIR microscope (72 scans, R=2 cm−1, 5 25 repeats).
