Interactions between nanofibers in fiber-surfactant suspensions: Theory of corresponding distances [PDF]

, 2014
We present the theory of corresponding distances for the interactions mediated by soft nano- structures in fibrous materials. These fibre-soft-fibre interactions are important for the design of fibrous materials as well as for the critical problem of ...

Kinetics and Thermodynamics Equilibrium of Nickel Metal Ions Sorption onto Carbon Nanofibers Irradiated by Ultrasonic Energy

Alchemy
In this work, we investigated the effects of the heavy metal initial concentration and the pH on the sorption of heavy metal ions onto carbon nanofibers using the liquid phase adsorption technique under ultrasonic energy irradiation. These data were then

Voltammetric probing of pH at carbon nanofiber–Nafion™–carbon nanofiber membrane electrode assemblies

Electrochimica Acta, 2012
Abstract Methods are developed for using a carbon nanofiber membrane electrode assembly (cnMEA) for three-electrode electrochemical measurements in unsupported liquid or gaseous media. The carbon nanofiber membrane (ca. 20 μm thickness) is hot-pressed from both sides onto a Nafion™ ion conductor film (ca. 50 μm thickness).

Formation and structure of calcium carbonate thin films and nanofibers precipitated in the presence of poly(allylamine hydrochloride) and magnesium ions [PDF]

, 2013
That the cationic polyelectrolyte poly(allylamine hydrochloride) (PAH) exerts a significant influence on CaCO₃ precipitation challenges the idea that only anionic additives have this effect. Here, we show that in common with anionic polyelectrolytes such
