  • Coherent coupling of Alkali atoms by random collisions
    'American Physical Society (APS)', 2015
    Co-Authors: Or Katz, Or Peleg, Firstenberg Ofer
    Abstract:

    Random spin-exchange collisions in warm Alkali vapor cause rapid decoherence and act to equilibriate the spin state of the atoms. In contrast, here we demonstrate experimentally and theoretically a coherent coupling of one Alkali Specie to another Specie, mediated by these random collisions. We show that, the minor Specie (potassium) inherits the magnetic properties of the dominant Specie (rubidium), including its lifetime (T1), coherence time (T2), gyromagnetic ratio, and SERF magnetic-field threshold. We further show that this coupling can be completely controlled by varying the strength of the magnetic field. Finally, we explain these phenomena analytically by modes-mixing of the two Species via spin-exchange collisions

  • Synthesis of Hydroxysodalite from Paper Sludge Ash Using NaOH-LiOH Mixtures
    HAL CCSD, 2017
    Co-Authors: Wajima Takaaki
    Abstract:

    International audienceHydroxysodalite zeolite was synthesized at 90 o C from paper sludge ash, which is industrial wastes in paper manufacturing, using NaOH-LiOH mixed solution. Paper sludge ash was discharged from paper making plant as industrial wastes, and the amount is increasing annually. The new utilization of paper sludge ash is desired. Hydroxysodalite can be used to remove HCl gas at high temperature, and there are papers for hydroxysodalite synthesis from various ashes, for example, coal fly ash. In my previous study, hydroxysodalite can be synthesized from paper sludge ash. However, little information can be available on the synthesis of hydroxysodalite from paper sludge ash. Therefore, we attempted to examine the synthesis of hydroxysodalite from paper sludge ash using NaOH-LiOH mixtures. Hydroxysodalite [Na6Al6Si6O24‧8H2O] was obtained in the mixed solution with Li / (Li + Na) ratios smaller than 0.25, while katoite [Ca3Al2(SiO4)(OH)8] was formed in the mixed solutions with the other molar ratios, due to the dissolution of gehlenite [Ca2Al2SiO7]. The observed concentrations of Si and Al in the solution during the reaction explain the synthesis of reaction products, which depends on Alkali Specie
