Self-assembly of an amphiphilic diblock copolymer in aqueous solutions: Effect of linear charge density of an ionogenic block

07-Jul-2010 | A. I. Kulebyakina, E. A. Lysenko, P. S. Chelushkin, A. V. Kabanov, A. B. Zezin, Polymer Science Series A, 2010

The effect of linear charge density of the ionogenic block on the self-assembly of the amphiphilic diblock copolymer based on polystyrene and poly(4-vinylpyridine) partially alkylated by ethyl bromide in aqueous solutions at pH 9 is studied by UV spectrophotometry and dynamic and static light ...

Aggregation behavior of poly([gamma]-benzyl-L-glutamate)-b-polyisoprene-b-poly([gamma]-benzyl-L-glutamate) rod-coil-rod triblock copolymer in N,N-dimethylformamide

25-Jun-2010 | Yoichi Ogata, Kazuhiro Iso, Satoshi Kura, Toshiyuki Hayakawa, Yutaka Makita, Journal of Polymer Science Part B: Polymer Physics, 2010

Solution property of poly([gamma]-benzyl-L-glutamate)-b-polyisoprene-b-poly([gamma]-benzyl-L-glutamate) (GIG copolymer) was studied by using dynamic light scattering and static light scattering for N,N-dimethylformamide (DMF) solution and DMF/toluene mixed solutions. GIG copolymer proved to ...

Structure and Gelation Mechanism of Tunable Guanosine-Based Supramolecular Hydrogels

08-Jun-2010 | Zheng Li; Lauren E. Buerkle; Maxwell R. Orseno; Kiril A. Streletzky; Soenke Seifert; Alexander M. Jamieson; Stuart J ..., Langmuir, 2010

The mechanism of gelation of 50/50 w/w mixtures of guanosine (G) and 2′,3′,5′-tri-O-acetylguanosine (TAcG) in aqueous 0.354 M KCl was investigated using a combination of static light scattering (SLS), polarized and depolarized dynamic light scattering (VV and VH DLS), small-angle neutron and ...

Columnar Organization of Head-to-Tail Self-Assembled Pt4 Rings

02-Jun-2010 | Peter D. Frischmann; Samuel Guieu; Raymond Tabeshi; Mark J. MacLachlan, Journal of the American Chemical Society, 2010

Coordination of Pt2+ to a family of tunable Schiff base proligands directs the 12-component self-assembly of disk-shaped Pt4 rings in a head-to-tail fashion. Aggregation of these S4 symmetric Pt4 macrocycles into columnar architectures was investigated by dynamic and static light scattering, NMR ...

Application of Asymmetric Flow-Field Flow Fractionation to the Characterization of Colloidal Dispersions Undergoing Aggregation

11-May-2010 | Marco Lattuada; Carlos Olivo; Cornelius Gauer; Giuseppe Storti; Massimo Morbidelli, Langmuir, 2010

The characterization of complex colloidal dispersions is a relevant and challenging problem in colloidal science. In this work, we show how asymmetric flow-field flow fractionation (AF4) coupled to static light scattering can be used for this purpose. As an example of complex colloidal ...

Hydrodynamic radius of polyethylene glycol in solution obtained by dynamic light scattering

01-May-2010 | K. L. Linegar, A. E. Adeniran, A. F. Kostko, M. A. Anisimov, Colloid Journal, 2010

In order to compare the size characterizations in poly(ethylene glycol) (PEG) obtained by dynamic light scattering (DLS) and small angle neutron scattering (SANS), DLS experiments were performed in various PEG solutions to ascertain the hydrodynamic radius. Data from the experiments were analyzed ...
