Triblock Polymer Engineering Enables Hydration‐Rich, High‐Performance, Fouling‐Resistant Interfaces

open access: yesAdvanced Functional Materials, Volume 36, Issue 36, 4 May 2026.
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.

Supercritical water deasphalting and desulphurization of heavy fuel oil with comprehensive molecular‐level analysis and techno‐economic analysis

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1727-1742, April 2026.
Supercritical water deasphalting. Abstract The removal of sulphur from heavy fuel oil (HFO) is essential to address environmental concerns and comply with the stringent regulations imposed by the International Maritime Organization (IMO) in 2020. Previously, the acceptable limit for sulphur was 3.5 wt.%, but it was recently changed to 0.5 wt.%.
