Microfluidic dispersion of mineral oil-seawater multiphase flows in the presence of dialkyl sulfonates, polysorbates, and glycols

Green Processing and Synthesis, 2013
The role of dispersants on hydrocarbon phase behavior in seawater is an important problem that influences marine environment ecology. Offshore petroleum and natural gas catastrophes, such as the Deepwater Horizon spill of 2010, motive the need to ...

Tuning Pre-Solution of an Amphiphilic Polymeric Dispersant with Low Acid-Value toward Colored-Ink Preparation

Applied Sciences, 2023
Recently, a variety of amphiphilic block copolymers for water-based color inks as pigment dispersants have been developed. Although such dispersants require both high adsorption of pigments and dispersion-stability in water, the most crucial issue is the

Multi-domain probiotic consortium as an alternative to chemical remediation of oil spills at coral reefs and adjacent sites

Microbiome, 2021
Background Beginning in the last century, coral reefs have suffered the consequences of anthropogenic activities, including oil contamination. Chemical remediation methods, such as dispersants, can cause substantial harm to corals and reduce their ...

Effect of Dispersants on the Properties of Ni Nanopowders Prepared by Liquid Phase Reduction Method

Crystals
Nickel nanoparticles were synthesized via liquid-phase reduction of NiCl2·6H2O with N2H4·H2O. The efficacy of different dispersing agents in preventing agglomeration was systematically compared, establishing a clear processing-dispersion correlation ...

Bioavailability Enhancement of Poorly Water-Soluble Drugs via Nanocomposites: Formulation–Processing Aspects and Challenges

Pharmaceutics, 2018
Drug nanoparticles embedded in a dispersant matrix as a secondary phase, i.e., drug-laden nanocomposites, offer a versatile delivery platform for enhancing the dissolution rate and bioavailability of poorly water-soluble drugs.

Acidic Biopolymers as Dispersants for Ceramic Processing

, 1990
Some acidic biopolymers serve as dispersants for colloidal processing of ceramics. One biopolymer we tested was alginate, a heteropolysaccharide containing two carboxylic sugar acids, D-mannuronic and D-guluronic. Kelp alginate was a suitable dispersant,

Dispersion processes [PDF]

Random Structures & Algorithms, 2018
We study a synchronous process called dispersion. Initially M particles are placed at a distinguished origin vertex of a graph G. At each time step, at each vertex v occupied by more than one particle at the beginning of this step, each of these particles moves to a neighbor of v chosen independently and uniformly at random.

Influences of molding processes and different dispersants on the dispersion of chopped carbon fibers in cement matrix

Heliyon, 2018
Chopped carbon fiber-reinforced cement composite (CFRC) has become one of the potential smart materials in recent years. The key process of preparing this kind of composite at the early stage is how to disperse carbon fibers evenly into the cement matrix
