The present invention is a fuel cell power plant that includes a fuel cell having a membrane electrode assembly (MEA), which is disposed between an anode support plate and a cathode support plate, and porous water transport plates adjacent the anode and cathode support plates. The porous water transport plates have interdigitated flow channels for the reactant gas streams to pass therethrough and conventional flow channels for a coolant stream to pass therethrough. The fuel cell power plant also has means for creating a pressure differential between the reactant gas streams and the coolant stream such that the pressure of the reactant gas streams is greater than the coolant stream. Incorporating the interdigitated flow channels into the porous water transport plates and operating the fuel cell at a pressure differential allows the coolant water to saturate the water transport plates thereby forcing the reactant gases into the anode and cathode support plate. This, in turn, increases the mass transfer of such gases into the support plates, thereby increasing the electrical performance of the fuel cell. Current densities of about 1.6 amps per square meter are achieved with air stochiometries of not over 2.50.

An apparatus or biopassage (A) includes a housing (20) dimensioned for receipt in a waterway during an increased flow event. The housing has a passage: (26) that provides a region of reduced flow generally irrespective of the flow external to the passage. A flow disrupter (50) disturbs laminar flow in the waterway above the passage. A preferred embodiment of the disrupter includes surfaces (52, 54) disposed in angled relation relative to a common apex (60) located above a longitudinal opening (30) of the passage. The surfaces include a series of peaks and valleys formed by angled planar portions (56) in one arrangement. A deflector (NC) is positioned upstream of an inlet end (40) of the passage to direct water away from the passage.

Also provided herein is a liposome comprising ribonucleic acid (RNA) molecules and a lipid mixture comprising DOTAP and cholesterol, wherein the DOTAP and cholesterol are present in the lipid mixture at a DOTAP:cholesterol ratio of about 3:1 by mass. Related cells comprising the liposome, populations of cells, and compositions are also provided. Methods of making a liposome and methods of using the liposome are further provided.

Disclosed is related to a synthetic peptide consisting of an amino acid sequence of ArgAsnProLeuGluGluThr (SEQ ID NO: 1). Also provided are a pharmaceutical composition benefic to eye care or eye health comprising the peptide, and a method for wound healing using the peptide.

The present invention is directed to a semiconductor multilayer structure and fabrication method thereof. A semiconductor multilayer structure comprises a silicon substrate, and a plurality of semiconductor layers, wherein at least one of the semiconductor layers is an aluminum contained nitride layer; and an indium-containing catalyst is utilized to enhance migration of aluminum in the aluminum contained nitride layer. A fabrication method is also disclosed here. By utilizing the indium-containing catalyst and/or gallium-containing catalyst, the aluminum migration can be enhanced to increase quality and flatness of the aluminum contained nitride buffer layer. Furthermore, the costs and energy consumption can be reduced too.
