The persistence length of adsorbed dendronized polymers

Giovanni Dietler, Michal Borkovec, Plinio Maroni, Andrey Mikhaylov

The persistence length of cationic dendronized polymers adsorbed onto oppositely charged substrates was studied by atomic force microscopy (AFM) and quantitative image analysis. One can find that a decrease in the ionic strength leads to an increase of the ...

Tuning the Aggregation of Titanate Nanowires in Aqueous Dispersions

László Forró, Endre Horvath

Electrophoretic and dynamic light scattering (DLS) measurements revealed that aggregation in aqueous dispersion of titanate nanowires (TiONWs) can be tuned by poly(diallyldimethylammonium) chloride (PDADMAC) polyelectrolyte. The nanowires possessed negativ ...

Soft nanofluidics governing minority ion exclusion in charged hydrogels

Fabien Patrick Wildhaber, Songmei Wu, Thomas Michael Braschler, Sidi Ahmed Bencherif

We investigate ionic partition of negatively charged molecular probes into also negatively charged, covalently crosslinked alginate hydrogels. The aim is to delimit the domain of validity of the major nanoelectrostatic models, and in particular to assess t ...

Dispersion Characteristics and Aggregation in Titanate Nanowire Colloids

László Forró, Arnaud Magrez, Endre Horvath, Plinio Maroni

Titanate nanowires (TiONWs) are synthesized through the hydrothermal method and characterized in acidic aqueous dispersions by using electrophoresis, dynamic light scattering, and atomic force microscopy. The TiONWs have a rodlike shape with an average len ...

Robust production of purified H-2 in a stable, self-regulating, and continuously operating solar fuel generator

Sophia Haussener, Miguel Antonio Modestino

The development of practical solar-driven electrochemical fuel generators requires the integration of light absorbing and electrochemical components into an architecture that must also provide easy separation of the product fuels. Unfortunately, many of th ...

Synthesis and properties of polymeric analogs of ionic liquids

Jutta Christine Wandrey

A number of methacrylate ionic monomers with different structures and mobilities of ionic centers were synthesized. The free-radical polymerization of these monomers in solution affords high-molecular-mass (M (sD) = 0.5 to 2.5 x 10(6)) thermally stable (T ...
