Abstract:
The invention includes antibodies that provide superior anti-coagulant activity by binding native human TF with high affinity and specificity. Antibodies of the invention can effectively inhibit blood coagulation in vivo. Antibodies of the invention can bind native human TF, either alone or present in a TF:VIIa complex, effectively preventing factor X binding to TF or that complex, and thereby reducing blood coagulation. Preferred antibodies of the invention specifically bind a conformational epitope predominant to native human TF, which epitope provides an unexpectedly strong antibody binding site.

Abstract:
A planar fuel cell stack, having generators that generate electricity by an electrochemical reaction of a fuel and an oxidizing agent, the generators arranged on a same plane. A beading unit and a protruding portion are formed on a fastening plate and a separator so as to improve structural stiffness thereof. Accordingly, the constituent elements of the stack are fastened with a substantially uniform conjoining pressure compared to a conventional planar stack, and the thickness of the stack of the present invention can be thinner than that of the conventional planar stack.

An apparatus for cleaning a gun barrel having striations is provided, which can uniformly clean an inner surface of the gun barrel by making cleaning members in contact with the inner surface of the gun barrel. The apparatus includes a cleaning device being in contact with the inner surface of the gun barrel as it is moved by a drive device installed inside a cylindrical main body. The cleaning device includes a plurality of divided plates dividedly provided inside the gun barrel in the form of a saddle and being slanted to correspond to a slope of the striations, cleaning members fixed to outer peripheries of the respective divided plates and being in contact with the inner surface of the gun barrel, a cam device converting a rotation of a drive motor installed inside the main body into a rectilinear movement in order to move the respective divided plates upward/downward, and a direction changing part coupling the cam device to the divided plates so that the divided plates go and return along the striations formed on the inner surface of the gun barrel and distributing a frictional force according to the movement of the divided plates forward/backward.
Abstract:
Co-sensitizers that co-adsorb with a sensitizing dye to the surface of an interconnected semiconductor oxide nanoparticle material increase the efficiency of photovoltaic cells by improving their charge transfer efficiency and reducing the back transfer of electrons from the interconnected semiconductor oxide nanoparticle material to the sensitizing dye.
Abstract:
A method of making a photovoltaic cell includes contacting a cross-linking agent with semiconductor particles, and incorporating the semiconductor particles into the photovoltaic cell.
Abstract:
A fuel cell system having an electricity generator that generates electricity by the electrochemical reaction between hydrogen and oxygen. The electricity generator includes a membrane electrode assembly with a conductive polymer membrane, and anode and cathode electrode layers on opposite sides of the conductive polymer membrane. The electricity generator has a pair of separator plates facing the anode and cathode electrode layers of the membrane electrode assembly and having channels through which flow hydrogen containing fuel or oxygen containing gas. There is also a pair of gaskets provided on opposite sides of the ionic conductive polymer to enclose each edge of the anode and cathode electrodes so that fluid leakage is prevented between the ionic conductive polymer membrane and the separator plates, wherein at least one of the gaskets is used as a voltage measuring gasket including a nonconductive first frame and a conductive second frame. The voltage measuring gasket having the conductive frame is used for measuring the voltage of the unit cell, thereby preventing a bipolar plate from being damaged.
Abstract:
A cell voltage measurer of a fuel cell stack and a fuel cell system using the same, the cell voltage measurer including a plurality of terminals electrically connected to a plurality of separators of the stack, respectively; and a plurality of wiring lines coupled to at least one of a plurality of fastening mechanisms and electrically connected to the plurality of terminals, respectively. With this configuration, at least one of the wiring lines is blocked or prevented from being short-circuited by heat generated in the fuel cell stack, and has a sample structure to ease an wiring operation. Since the cell voltage of the fuel cell stack is stably measured to thereby measure (or check) the deterioration of a certain cell (or cell unit), the fuel cell stack is blocked or prevented from being suddenly stopped due to excess deterioration of the certain cell (or cell unit).
