Abstract: The present invention provides a natural polymeric nanofiber, which is made by a natural polymeric solution under an applied field control spinning process, wherein the natural polymeric solution comprises: a natural polymeric material, an inorganic salt and/or an enzyme; the present invention further provides a method for preparing the natural polymeric nanofibers. The nature polymeric nanofibers of the present invention have a smaller fiber diameter, and have higher safety and practicability.

Abstract: The present disclosure provides a valuable metal selectively adsorbing electrode, including: an electrode formed by a carbon-containing material; and a protein of a bacterium of genus Tepidimonas immobilized on the electrode formed by a carbon-containing material to form the valuable metal selectively adsorbing electrode, wherein the valuable metal includes gold, palladium, silver or indium.

Abstract: A method for electrochemically selectively removing ions using a composite electrode is provided. The composite electrode includes a composite having a carbon support and an inorganic material immobilized on the carbon support.

Abstract: A binder for capacitive deionization electrode is provided, which is formed by reacting a polyether polyol, a diisocyanate, and a diol having a hydrophobic side chain. The binder may bind an electrode material and to form a capacitive deionization electrode. The electrode material and the binder may have a weight ratio of 90:5 to 90:25.

Abstract: A method of manufacturing a composite material is provided. First, graphene oxide and activated carbon are provided individually. Graphene oxide and activated carbon are added into an alcohol to form a mixture. Then, the mixture is heated by microwave in a single step, so that graphene oxide is chemically reduced to form graphene at the active sites of the surface of the activated carbon uniformly, thereby forming a composite material. The embodied composite material is suitable for being the electrodes of the capacitive deionization (CDI) and supercapacitor application.

Abstract: A forward osmosis process is provided, which includes separating a feed part and a draw solution part by a semi-permeable film. An ionic liquid is introduced into the draw solution part, and brine is introduced into the feed part. The brine has an osmotic pressure lower than that of the ionic liquid, so that pure water of the brine permeates through the semi-permeable film, enters the draw solution part, and mixes with the ionic liquid to form a draw solution. The draw solution was obtained out of the draw solution part to be left to stand at room temperature, so that the draw solution separated into a water layer and an ionic liquid layer.
