Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces
A molecularly engineered triblock polymer (PHZ) rapidly reorganizes into a hydration‐rich interfacial layer on diverse surfaces, strongly suppressing hydrophobic attraction and fouling. The triblock polymer provides robust energy and steric barriers to oily foulants, enabling high‐performance antifouling at ultralow dosage.

25 g of oil sands extracted by dynamic accelerated solvent extraction, yielding 177 mL of bitumen–toluene extract and clean dried solids in approximately 12 min. Abstract Determining the oil, water, and solids (OWS) contents of oil sand is essential to many aspects of the oil sands industry including mine planning, optimization of extraction processes,

A novel multiphase composite was developed to prevent premature failure of waterproofing layers in pig houses. The system, comprising polyurethane, asphalt, and calcium carbonate, achieves a 1.35 MPa bonding strength and resists corrosion via a synergistic crosslinking, buffering, and passivation mechanism.

Experimental methods in chemical engineering: Electrospinning
Abstract Electrospinning produces micro‐ and nanofibres by forcing a polymeric solution through a fine needle in an electric field that produces a filament that accumulates onto a collector plate. The fibre morphology depends on solution properties, distance between needle and plate, feed rate, and electric field intensity.

OVER-STABILIZED BITUMEN EMULSIONS MADE FROM EMULSIFIERS FOR SLOW-SETTING EMULSIONS
Formulations of road over-stabilized cationic bitumen emulsions with orthophosphoric, sulfuric and hydrochloric acids and cationic emulsifiers for slowly disintegrating emulsions have been designed. The physical and mechanical properties of the manufactured over-stabilized bitumen emulsions and their breaking behavior were determined.

Assessing pavement sustainability requires jointly evaluating structural performance and environmental impacts, yet these dimensions are often analyzed separately. This study proposes an integrated framework combining mechanistic–empirical pavement design and life cycle assessment (LCA) to quantify the structural–environmental trade‐off associated with
