The Structural Dispersity of Oligoethylene Glycol-Containing Polymer Brushes Determines Their Interfacial Properties

Harm-Anton Klok, Alberto Ongaro, Irene Filipucci

Ought to their bioinert properties and facile synthesis, poly[(oligoethylene glycol)methacrylate]s (POEGMAs) have been raised as attractive alternatives to poly(ethylene glycols) (PEGs) in an array of (bio)material applications, especially when they are ap ...

Ion Adsorption Enhances Apparent Nonelectrostatic Attraction between Monomers in Polyelectrolyte Brushes

Harm-Anton Klok, Xingyu Xu, Jing Yu

Polyelectrolyte brushes are responsive to salt in the environment, and this has found broad applications in antifouling, biolubrication, and drug delivery. Salt primarily influences the conformation of the polyelectrolytes through ion adsorption. While ion ...

Extraction and controlled functionalization of lignin for materials applications

Stefania Bertella

Lignin is a renewable aromatic polymer that due to its abundance and unique chemical structure is a promising candidate to replace aromatic materials that are currently sourced from fossil oil. The same structure of lignin poses however drawbacks for its v ...

A novel reactor concept for thermal integration of naphtha reforming with propane ammoxidation

Alimohammad Bahmanpour, Samira Ebrahimian

In this study, propane ammoxidation as an exothermic process is thermally coupled with the endothermic naphtha reforming process which resulted in the elimination of the naphtha reforming furnaces. Both processes are available in petrochemical plants. Naph ...
