Conductive metal-organic frameworks (c-MOFs) are promising active electrode materials for electrochemical double-layer capacitors with a performance that already exceeds most carbon-based materials. However, their excellent supercapacitance is primarily based on organic or alkaline electrolytes, which largely impede broad applications and sustainabilities. In this work, we propose new synthesis...

Controlling the structure and morphology of porous electrode materials is an effective strategy for realizing a high surface area and efficient paths for ion diffusion. Moreover, excellent electrical conductivity can significantly decrease the internal resistance of an electrode by the formation of a conductive network and facilitate the application of electrostatic charges, which favors the ac...

Title of Dissertation: THE ROLE OF CHARGE IN SOLVATION AT LIQUID/LIQUID INTERFACES Carmen Louise Huffman, Doctor of Philosophy, 2005 Dissertation directed by: Professor Robert A. Walker Department of Chemistry and Biochemistry This dissertation describes the development and characterization of new surfactants, dubbed “molecular rulers,” that provide an upper limit to the dipolar width in aqueou...

The concentration dependence of the surface tension of single and mixed electrolyte aqueous solutions is studied, based on the assumption that the surface layer can be treated as a separate phase located between vapor and bulk liquid phases. The mean spherical approximation modified by Lu et al. [J.-F. Lu, Y.-X. Yu, Y.-G. Li, Fluid Phase Equilibria 85 (1993) 81–100] is used to calculate the act...

The structure of an aqueous solution of sodium chloride at a planar electrode is investigated by integral equation techniques. With the central force water model the aqueous electrolyte is modelled as a mixture of sodium and chloride ions and partially charged hydrogen and oxygen atoms interacting via effective spherically symmetric pair potentials. The correlation functions obtained from the O...

In this work, existing and modified activity coefficient models are examined in order to assess their capabilities to describe the properties of aqueous solution droplets relevant in the atmosphere. Five different water-organicelectrolyte activity coefficient models were first selected from the literature. Only one of these models included organics and electrolytes which are common in atmospher...

Graphene is a promising material for applications in aqueous electrolyte environments. To explore the impact of such environments on graphene’s electrical properties, we performed Hall bar measurements on electrolyte-gated graphene. Assuming a Drude model, we find that the room temperature carrier mobility reaches 7,000 cm 2 /Vs, the highest mobility recorded for graphene in an aqueous electrol...

Electrostatic stabilization is reduced in its efficiency in an electrolyte-containing environment. The effect of electrolyte concentration is mostly described as negative factor for dispersion stabilization. Usually, zeta potential and physical stability decrease at increasing electrolyte concentration. The purpose of the present study was to measure the surface properties of nanotubes in aqueo...

The aqueous and ethanolic extract of leaves of Coleus aromaticus was evaluated for diuretic activity. Both extracts were evaluated by determination of urine volume and electrolyte concentration in albino rats. Results revealed that both the aqueous and ethanolic extract at dose 500mgl kg showed significant diuretic activity by increasing the total volume of urine and concentration electrolyte. ...
