ClearProgress of Dispersants for Coal Water Slurry
This review examined the development and current state of dispersants used in coal water slurry formulations, covering both traditional and novel dispersant types and their mechanisms for improving slurry concentration.
Synthesis of Water-Dispersible Poly(dimethylsiloxane) and Its Potential Application in the Paper Coating Industry as an Alternative for PFAS-Coated Paper and Single-Use Plastics
Researchers synthesized water-dispersible polydimethylsiloxane (PDMS) and evaluated its potential as a delivery agent and surface-treatment compound in cosmetic and biomedical applications. The water-dispersible PDMS formulations showed stable performance and could enable silicone-based functionality in aqueous formulations without conventional solvents.

Researchers investigated the stabilization of composite water-coal fuel (WCF) using carbon submicron material produced by plasma-chemical conversion of organic wastewater and amino alcohols as chemical additives. The study examined how these additives influence the rheological properties, viscosity, and stability of coal-water slurries with 61% solid-phase concentration.
Effect of water-soluble polymers on the transport of functional group-modified polystyrene nanoplastics in goethite-coated saturated porous media
Researchers examined how polyacrylic acid (a common water-soluble polymer) influences nanoplastic migration through iron oxide-coated and uncoated quartz sand, finding that it inhibits transport in plain sand but promotes it in iron-coated media by forming an ecological corona on nanoplastic surfaces that alters electrostatic interactions and competes with iron binding sites.

This study investigated how natural organic matter stabilizes fragmental polystyrene nanoplastics in aqueous environments, finding that humic and fulvic acid coatings reduce aggregation and enhance colloidal stability, affecting nanoplastic transport and bioavailability.
Carrier Flotation of Low-Rank Coal with Polystyrene
This paper explores using polystyrene as a carrier material to improve flotation of low-rank coal during processing. The study is relevant to understanding how polystyrene microplastics behave in water and their tendency to adsorb onto other surfaces.
Oil‐ and water‐resistant paper substrate using blends of chitosan‐graft‐polydimethylsiloxane and poly(vinyl alcohol)
Researchers developed a plastic- and fluorine-free coating approach for oil and water repellent paper substrates using blends of poly(vinyl alcohol) and chitosan-graft-polydimethylsiloxane copolymer, offering an economical alternative to conventional coatings that contribute to microplastic contamination.
Functionalization of polymers and nanomaterials for water treatment, food packaging, textile and biomedical applications: a review
This review covers surface functionalization strategies for polymers and nanomaterials to improve adhesion, wettability, biocompatibility, and performance in water treatment, food packaging, and biomedical applications. Functionalization is highlighted as an approach to expand the utility of inert conventional polymers and nanomaterials without the environmental drawbacks of additive-laden plastic products.
Molecular simulation of the slurrying mechanism in microplastic semi-coke water slurry
Researchers used molecular simulation to study how microplastic particles influence the slurrying mechanism in semi-coke water slurry fuel systems, finding that plastic surfaces alter slurry viscosity and particle interaction dynamics.
Transport of polystyrene nanoplastics in porous media: Combined effects of two co-existing substances
Researchers studied how cationic and anionic surfactants interact with natural organic matter (humic acid and sodium alginate) to control polystyrene nanoplastic transport through porous media, finding that the dominant mobility mechanism switched from electrostatic (with cationic surfactants) to hydrophobic (with anionic surfactants), with organic matter amplifying each surfactant's effect.
Transport of alumina nanoparticles in natural waters and water saturated porous media- an analysis of the effect of various environmental parameters
This study examined how water chemistry affects the stability, settling, and transport of alumina nanoparticles in aquatic environments and saturated porous media. Understanding nanoparticle fate in the environment is important because engineered nanoparticles in products can behave similarly to nanoplastics, accumulating in soil and water ecosystems.
