Self-healing polyacrylic acid hydrogels

18-09-2013 | Umit Gulyuz; Oguz Okay, Soft Matter, 2013

pH responsive physical gels were prepared by micellar copolymerization of acrylic acid with 2 mol % stearyl methacrylate in the solution of worm-like sodium dodecyl sulfate micelles. The physical gels are insoluble in water and exhibit time-dependent dynamic moduli, high Young’s modulus (6 – 53 ...

Low-temperature, solution-processed, layered V2O5 hydrate as the hole-transport layer for stable organic solar cells

11-09-2013 | Gerardo Terán-Escobar; Jonas Pampel; José M. Caicedo; Mónica Lira-Cantú, Energy & Environmental Science, 2013

Layered V2O5 hydrate has been applied as the hole transport layer (HTL) in organic solar cells (OSCs). V2O5 is obtained from a sodium metavanadate solution in water under ambient conditions, resulting in a final thin film of formula V2O5·0.5H2O. The 0.5 water molecules are not removed from the ...

Foam‐like polymer/clay aerogels which incorporate air bubbles

08-09-2013 | Rocco P. Viggiano, Matthew D. Gawryla, David A. Schiraldi, Journal of Applied Polymer Science, 2013

ABSTRACT The structure/property relationships of polymer/clay aerogels interfused with uniformly distributed air bubbles were examined. Through the incorporation of a polyelectrolyte in a montmorillonite(MMT) clay solution, the viscosity was systematically changed by the addition of ions with ...

Molecular Dynamics Simulation of SDS and CTAB Micellization and Prediction of Partition Equilibria with COSMOmic

04-09-2013 | Sandra Storm; Sven Jakobtorweihen; Irina Smirnova; Athanassios Z. Panagiotopoulos, Langmuir, 2013

Molecular dynamics (MD) simulations of the self-assembly of different ionic surfactants have been performed in order to obtain representative micellar structures. Subsequently, these structures were used to predict the partition behavior of various solutes in these micelles with COSMOmic, an ...

Phase Equilibrium of the Quaternary System Na2SO4–MgSO4–(NH4)2SO4–H2O at 0 °C

04-09-2013 | Jing Zhang; Hong-Fei Guo; Ji-Lin Cao; Rui-Jie Fan, Journal of Chemical & Engineering Data, 2013

The solubilities of the ternary system MgSO4–(NH4)2SO4–H2O and the quaternary system Na2SO4–MgSO4–(NH4)2SO4–H2O at 0 °C were measured, and the phase diagrams of these two systems were plotted. On the basis of the phase diagrams obtained, we analyzed each saturation point and crystalline region. ...
