    Interactions between surfactants and solids can be understood completely by studying desorption as well as adsorption. During this report period, desorption of tetradecyl trimethyl ammonium chloride (TTAC) and pentadecylethoxylated nonyl phenol (NP-15) mixtures from the alumina-water interface was studied. It was found that in tetradecyl trimethyl ammonium chloride (TTAC) rich mixtures the desorption of the two surfactants from the interface was controlled by the TTAC and was similar to the desorption of TTAC alone. At high concentrations the adsorption of the mixtures was reversible. At low concentrations, however, the desorption of TTAC showed some positive hysteresis. Since the adsorption of NP-15 was dependent upon the presence of TTAC, polyethoxylated nonyl phenol (NP-15) also, like TTAC, showed some positive desorption hysteresis. In contrast, the desorption of both these surfactants from a 1:1 TTAC:NP-15 mixture showed some negative hysteresis. It was clear that the desorption behavior of the components in the mixture system studied here can be controlled by adjusting the ratio of the two surfactants. With an increase of NP-15 in the mixtures, the desorption of surfactants becomes easier. In an attempt to understand adsorption and desorption behavior of mixed surfactant systems, regular solution theory was used to model the interactions between tetradecyl trimethyl ammonium chloride (TTAC) and nonyl phenol polyethoxylated alcohol with fifteen ethylene oxide groups (NP-15). The interaction parameter P and the monomer concentrations were calculated for different mixtures.

  7. Solar neutrinos and the solar composition problem

    E-Print Network [OSTI]

    Standard solar models (SSM) are facing nowadays a new puzzle: the solar composition problem. New determinations of solar metal abundances lead SSM calculations to conflict with helioseismological measurements, showing discrepancies that extend from the convection zone to the solar core and can not be easily assigned to deficiencies in the modelling of the solar convection zone. We present updated solar neutrino fluxes and uncertainties for two SSM with high (old) and low (new) solar metallicity determinations. The uncertainties in iron and carbon abundances are the largest contribution to the uncertainties of the solar neutrino fluxes. The uncertainty on the ^14N+p -> ^15O+g rate is the largest of the non-composition uncertainties to the CNO neutrino fluxes. We propose an independent method to help identify which SSM is the correct one. Present neutrino data can not distinguish the solar neutrino predictions of both models but ongoing measurements can help to solve the puzzle.

  8. Predictability of price movements in deregulated electricity markets

    Uritskaya, Olga Y


    In this paper we investigate predictability of electricity prices in the Canadian provinces of Alberta and Ontario, as well as in the US Mid-C market. Using scale-dependent detrended fluctuation analysis, spectral analysis, and the probability distribution analysis we show that the studied markets exhibit strongly anti-persistent properties suggesting that their dynamics can be predicted based on historic price records across the range of time scales from one hour to one month. For both Canadian markets, the price movements reveal three types of correlated behavior which can be used for forecasting. The discovered scenarios remain the same on different time scales up to one month as well as for on- and off- peak electricity data. These scenarios represent sharp increases of prices and are not present in the Mid-C market due to its lower volatility. We argue that extreme price movements in this market should follow the same tendency as the more volatile Canadian markets. The estimated values of the Pareto indi...
