    Abstract: Disclosed herein is a method of manufacturing inorganic hollow yarns, such as cermets, oxide-non oxide composites, poorly sinterable non-oxides, and the like, at low costs. The method includes preparing a composition comprising a self-propagating high temperature reactant, a polymer and a dispersant, wet-spinning the composition through a spinneret to form wet-spun yarns, washing and drying the wet-spun yarns to form polymer-self propagating high temperature reactant hollow yarns, and heat-treating the polymer-self propagating high temperature reactant hollow yarns to remove a polymeric component from the polymer-self propagating high temperature reactant hollow yarns while inducing self-propagating high temperature reaction of the self-propagating high temperature reactant to form inorganic hollow yarns. The composition comprises 45˜60 wt % of the self-propagating high temperature reactant, 6˜17 wt % of the polymer, 0.1˜4 wt % of the dispersant, and the balance of an organic solvent.

    Abstract: The present invention provides a bioelectrochemical system for removing a polyvalent ion present in seawater etc., capable of producing electricity. The bioelectrochemical system according to the present invention comprises: an anode chamber comprising an anode which accommodates an electron produced when treating an organic material in wastewater with a microorganism; a cathode chamber comprising a cathode receiving the electron from the anode, for producing a hydroxide ion by reacting the electron with oxygen and water provided from the outside, and depositing the polyvalent ion inside an electrolyte by using the hydroxide ion; and an anion exchange membrane for blocking the polyvalent ion inside the electrolyte from moving to the anode chamber. Also, the present invention provides the bioelectrochemical system capable of removing the polyvalent ion present in seawater etc., and simultaneously producing hydrogen. The present invention comprises: the anode chamber, provided with the anode to which electrochemically active bacteria are attached, for producing the electron by having organic wastewater, as a substrate, injected thereto; the cathode chamber, provided with the cathode, for removing the polyvalent ion and simultaneously producing a hydrogen gas by having seawater, as an electrolyte, injected thereto; the anion exchange membrane for separating the anode chamber and the cathode chamber and preventing the polyvalent cation in seawater from moving to the anode chamber; and a power source connected between the anode and the cathode.
