Amphiphilic block copolymer self‐assemblies of poly(NVP)‐b‐poly(MDO‐co‐vinyl esters): Tunable dimensions and functionalities

10-Oct-2015 | Guillaume G. Hedir, Anaïs Pitto‐Barry, Andrew P. Dove, Rachel K. O'Reilly, Journal of Polymer Science Part A: Polymer Chemistry, 2015

ABSTRACT Functional, degradable polymers were synthesized via the copolymerization of vinyl acetate (VAc) and 2‐methylene‐1,3‐dioxepane (MDO) using a macro‐xanthate CTA, poly(N‐vinylpyrrolidone), resulting in the formation of amphiphilic block copolymers of poly(NVP)‐b‐poly(MDO‐co‐VAc). The ...

Colloid Deposit Morphology and Clogging in Porous Media: Fundamental Insights Through Investigation of Deposit Fractal Dimension

05-Oct-2015 | Eric J. Roth; Benjamin Gilbert; David C. Mays, Environmental Science & Technology, 2015

Experiments reveal a wide discrepancy between the permeability of porous media containing colloid deposits and the available predictive equations. Evidence suggests that this discrepancy results, in part, from the predictive equations failing to account for colloid deposit morphology. This ...

Role of Cosolute–Protein Interactions in the Dissociation of Monoclonal Antibody Clusters

02-Oct-2015 | Thomas M. Scherer, Journal of Physical Chemistry B, 2015

The solution thermodynamics and interactions of a reversibly self-associating monoclonal IgG1 antibody (mAb1) have been investigated as a function of cosolute type (NaCl, NaSCN, Arginine-HCl) and cosolute concentration over a wide range of protein concentrations (1–275 mg/mL) using static light ...

Thermodynamics of Aqueous Methylcellulose Solutions

24-Sep-2015 | John W. McAllister; Peter W. Schmidt; Kevin D. Dorfman; Timothy P. Lodge; Frank S. Bates, Macromolecules, 2015

The weight-average molecular weight Mw, z-average radius of gyration Rg, and second virial coefficient A2 have been determined between 15 and 52 °C for dilute aqueous solutions of methylcellulose (MC) with three different molecular weights and constant degree of substitution (DS) of 1.8 using ...

Rapid and Facile Formation of P3HT Organogels via Spin Coating: Tuning Functional Properties of Organic Electronic Thin Films

18-Aug-2015 | Cameron S. Lee, Wen Yin, Adam P. Holt, Joshua R. Sangoro, Alexei P. Sokolov, Mark D. Dadmun, Advanced Functional Materials, 2015

Poly(3‐hexyl thiophene) (P3HT) is widely regarded as the benchmark polymer when studying the physics of conjugated polymers used in organic electronic devices. P3HT can self‐assemble via π–π stacking of its backbone, leading to an assembly and growth of P3HT fibrils into 3D percolating ...

LCST and UCST in One: Double Thermoresponsive Behavior of Block Copolymers of Poly(ethylene glycol) and Poly(acrylamide-co-acrylonitrile)

04-Aug-2015 | Florian Käfer; Fangyao Liu; Ullrich Stahlschmidt; Valérie Jérôme; Ruth Freitag; Matthias Karg; Seema Agarwal, Langmuir, 2015

The change in thermoresponsive behavior from a single phase transition of upper critical solution temperature (UCST)-type of an acrylamide-acrylonitrile copolymer (AAm-co-AN) to a double responsive behavior (LCST-UCST-type (LCST, lower critical solution temperature)) in water by the introduction ...
