Patent application numberTitlePublished
20120133540VOLTAGE-TIME CONVERTERS AND TIME-DOMAIN VOLTAGE COMPARATORS INCLUDING THE SAME - Provided is a time-domain voltage comparator including a voltage-time converter. The voltage-time converter includes a conversion unit and an output unit. The conversion unit includes a first MOS transistor which shifts a voltage level of the first detection node according to an external first voltage signal, and a second MOS transistor which shifts a voltage level of the second detection node according to an external second voltage signal. The output unit generates first and second output signals in response to voltages of the first and second detection nodes. The output unit determines a shifted time of the first output signal according to a voltage level of the first detection node and determines a shifted time of the second output signal according to a voltage level of the second detection node.05-31-2012
20110294040PROTON-CONDUCTING HYBRID GLASS AND METHOD FOR MANUFACTURING THE SAME - Proton-conducting hybrid glass and a method for manufacturing the same. The proton-conducting hybrid glass has CsPWA created inside the pores of borosilicate glass. The proton-conducting hybrid glass can be used as an electrolyte for electrochemical devices, such as fuel cells and sensors. When the proton-conducting hybrid glass is used as an electrolyte membrane for a fuel cell, excellent thermal and chemical stability is realized in the range from a high temperature to an intermediate temperature of 120° C. A high proton conductivity of 1012-01-2011
20110183231HIGH MOLECULAR NANOCOMPOSITE MEMBRANE FOR DIRECT METHANOL FUEL CELL, AND MEMBRANE-ELECTRODE ASSEMBLY AND METHANOL FUEL CELL INCLUDING THE SAME - A high molecular nanocomposite membrane for a Direct Methanol Fuel Cell (DMFC), and a Membrane-Electrode Assembly (MEA) and a methanol fuel cell including the same membrane. The high molecular nanocomposite membrane for a DMFC includes a Nafion® high molecular membrane in which hydrophobic silica nanoparticles made of a silane compound having a water repellent functional group are dispersed. Since the high molecular nanocomposite membrane for a DMFC has lower permeability of methanol than a commercially available Nafion® high molecular membrane, the MEA fabricated using the high molecular nanocomposite membrane has little crossover of reaction fuel at the negative electrode. In addition, the methanol fuel electrode fabricated using the MEA that includes the high molecular nanocomposite membrane can decrease fuel loss and voltage loss.07-28-2011
20110129675MATERIAL INCLUDING GRAPHENE AND AN INORGANIC MATERIAL AND METHOD OF MANUFACTURING THE MATERIAL - A material including: graphene; and an inorganic material having a crystal system, wherein a crystal plane of the inorganic material is oriented parallel to the (0001) plane of the graphene. The crystal plane of the inorganic material has an atomic arrangement of a hexagon, a tetragon, or a pentagon.06-02-2011
