Amphiphilic Non‐Isocyanate Polyurethane Coatings With Tunable Antifouling and Fouling‐Release Performance: A Log‐Ratio Assessment Framework

open access: yesAdvanced Materials Interfaces, EarlyView.
Amphiphilic non‐isocyanate polyurethane (NIPU) coatings containing reactive hydrophobic poly(dimethylsiloxane) (PDMS) and hydrophilic methoxy poly(ethylene glycol) (MPEG) prepolymers for marine antifouling (AF) and fouling‐release (FR) applications were investigated. The coatings were evaluated with a set of representative marine foulants.

Experimental aeroacoustics study on jet noise reduction using tangential air injection [PDF]

open access: yes, 2011
PhDAircraft jet exhausts are a source of undesirable noise and continue to be an area of investigation driven by increasingly stringent regulation. The noise is produced by the unsteady mixing of the jet with the surrounding air and is dominated by the ...

Electrospun PCL Fibers Enhanced With Molecularly Imprinted Polymers for the Adsorption of Pharmaceutical Drugs

open access: yesAdvanced Materials Interfaces, EarlyView.
Electrospun polycaprolactone fiber mats embedded with diclofenac‐imprinted polymers were developed to remove persistent pharmaceutical pollutants from water. The materials showed improved adsorption and retention compared to pure polymer mats, with performance influenced by fiber diameter and polymer content.

Control of Bacterial Attachment on Macroporous PDMS/Paraffin SLIPS With Varying Lubricant Viscosity

open access: yesAdvanced Materials Interfaces, EarlyView.
Slippery liquid‐infused porous surfaces (SLIPS) prepared from macroporous PDMS, infused with medical‐grade paraffins, were systematically investigated regarding the correlation of viscosity, surface corrugation, bulk porosity, and bacterial resistance. Substrate porosity was found to dominate lubricant stabilization and the antifouling activity.
