All-Aqueous SI-ARGET ATRP from Cellulose Nanofibrils Using Hydrophilic and Hydrophobic Monomers

Porous Materials from Cellulose Nanofibrils

Hydrophobic and hydrophilic interactions in aqueous mixtures of alcohols at a hydrophobic surface.

Aqueous solutions of alcohols are interesting because of their anomalous behavior that is believed to be due to the molecular structuring of water and alcohol around each other in solution. The interfacial structuring and properties are significant for application in alcohol purification processes and biomolecular structure. Here we study aqueous mixtures of short alcohols (methanol, ethanol, 1...

سنتز نانوکامپوزیت‌های پلی‌استیرن/‌MCM–41 به روش‌های AGET ATRP و ARGET ATRP

نانوکامپوزیت‌های پلی‌استیرن/MCM–41 به روش پلیمرشدن رادیکالی انتقال اتم (ATRP) در دمای 110 درجه سلسیوس سنتز شدند. روش‌های آغاز فعال‌کننده‌هایی که با انتقال الکترون تولید می‌شوند (AGET) و فعال‌کننده‌هایی که با انتقال الکترون بازتولید می‌شوند (ARGET) به­ عنوان دو روش نوین آغاز در ATRP به­ کار گرفته شدند. ساختار ویژه، مساحت سطح، اندازه ذرات و توزیع آنها و ساختار اسفنجی و حفره‌ای نانوذرات MCM–41 سنت...

Data in support of dual-functionalized cellulose nanofibrils prepared through TEMPO-mediated oxidation and surface-initiated ATRP

We previously studied a suitably 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO)-oxidized cellulose nanofibrils (TOCNs) that can be further functionalized with initiating sites and overcame the obstacle of performing atom transfer radical polymerization (ATRP) in the presence of neutral carboxylic acid sodium salt groups [1]. Herein, characterization of the modified TOCNs and of the products from ...

Fabrication of fibrillosomes from droplets stabilized by protein nanofibrils at all-aqueous interfaces

All-aqueous emulsions exploit spontaneous liquid-liquid separation and due to their water-based nature are particular advantageous for the biocompatible storage and processing of biomacromolecules. However, the ultralow interfacial tensions characteristic of all-aqueous interfaces represent an inherent limitation to the use of thermally adsorbed particles to achieve emulsion stability. Here, we...
