Abstract:
Disclosed is a sterilizing catalyst, a sterilizing device and a sterilizing system, the sterilizing catalyst includes a metal lattice including a metal oxide, and an oxygen vacancy-inducing metal that is integrated or encompassed within the metal lattice. The metal oxide is an oxide of a divalent or multivalent metal. The oxygen vacancy-inducing metal has an oxidation number lower than that of the divalent or multivalent metal.
Abstract:
A drinking water filter system includes; a filter unit including; a first electrode and a second electrode disposed separate from and substantially opposite to the first electrode, wherein at least one of the first electrode and the second electrode is a filter layer, and a voltage applying device which alternately applies a forward voltage and a reverse voltage between the first electrode and the second electrode to sterilize and regenerate the at least one filter layer.
Abstract:
In the quorum sensing antagonist blocking the communication in bacteria, the method for preventing biofilm formation using this quorum sensing antagonist and the method for reducing the bacterial contamination, the quorum sensing antagonist contains the homoserine lactone moiety and sulfanylethanoyl group, and has a similar chemical structure to that of the autoinducer which is produced by bacteria as a signal, whereby the quorum sensing antagonist can inhibit the formation of biofilm and reduce the bacterial contamination as well.
Abstract:
A filter unit may include an electrode structure, a fluid-purifying flow path, and a pH adjusting chamber. The electrode structure may include a cathode, a cation exchange membrane, an anion exchange membrane, and an anode in that order. The fluid-purifying flow path may be at least one of a path in the cathode, between the cathode and the cation exchange membrane, between the anion exchange membrane and the anode, and in the anode. The fluid-purifying flow path may include an adsorption function. The pH adjusting chamber may be between the cation exchange membrane and the anion exchange membrane. The pH adjusting chamber may be configured to control the pH of the fluid in the fluid-purifying flow path.
Abstract:
A draw solute for forward osmosis may include a copolymer including a first structural unit where a temperature-sensitive side chain is graft polymerized, and a second structural unit including a hydrophilic functional group. The temperature-sensitive side chain may include a structural unit for a side chain including a temperature-sensitive moiety.
Abstract:
A paper cup holder having a disposable teacup shape for a cup is provided. The paper cup holder includes inner and outer lining portions, finger portions, intermediate supporting portions, first and second half crossing cuts, and fastening portions. The inner lining portion wraps around the cup. The outer lining portion is provided around the inner lining portion, and the outer lining portion is configured to wrap around the inner lining portion so as to shield heat from the cup, and wherein the out lining portion comprises first and second edges. The finger hole portions accept one or two fingers. The intermediate supporting surface is provided between the finger hole portions.
