A gas particulate filter well-suited for, but not limited to, removing airborne particulates from air. According to one embodiment, the filter is a composite structure including a porous support and an ionomer coating. The porous support is preferably made of a material designed to endow the filter with good mechanical properties. The pores of the porous support are preferably micron or smaller straight pores. The ionomer coating, which is applied to the porous support but does not completely seal the pores of the porous support, is preferably selected to provide the filter with good filtering properties and regeneration through controlled ionomer hydration/dehydration and corresponding ionomer swelling and contraction.

The case cable management has a shell, a circuit board, multiple sockets and a cover. The shell has a bottom board and a sidewall. The circuit board is attached securely to the bottom board of the shell. The sockets are mounted through the sidewall of the shell and have multiple terminals connected securely to the circuit board. The cover covers the shell. Multiple power lines are mounted through the sidewall of the shell to connect the circuit board and sockets to a power supply and cables from computer apparatuses are connected to the sockets to receive electric power. Different cables can be distinguished clearly and conveniently for simplified cable routing to avoid confusion and facilitate replacement.

A hard disk drive case has a base, a cover and a fan assembly. The base has an inner surface, a sidewall and an outlet formed through the sidewall of the base. The cover is mounted onto the base and has an inlet formed through the cover. The fan assembly is mounted on the inner surface of the base, is surrounded by the sidewall of the base and has a bracket and a hood. The bracket has an airway and a fan. The airway is flared and communicates with the outlet. The fan is mounted in the airway. The hood corresponds to and covers the airway to form a chamber communicating with the outlet and has a hole defined through the hood, corresponding to the fan and allowing the fan to extract air from the inlet and to guide air toward the outlet efficiently.

A solid polymer electrolyte composite membrane and method of manufacturing the same. According to one embodiment, the composite membrane comprises a rigid, non-electrically-conducting support, the support preferably being a sheet of polyimide having a thickness of about 7.5 to 15 microns. The support has a plurality of cylindrical pores extending perpendicularly between opposing top and bottom surfaces of the support. The pores, which preferably have a diameter of about 0.1 to 5 microns, are made by plasma etching and preferably are arranged in a defined pattern, for example, with fewer pores located in areas of high membrane stress and more pores located in areas of low membrane stress. The pores are filled with a first solid polymer electrolyte, such as a perfluorosulfonic acid (PFSA) polymer. A second solid polymer electrolyte, which may be the same as or different than the first solid polymer electrolyte, may be deposited over the top and/or bottom of the first solid polymer electrolyte.

A diffusion media and a process for its fabrication are provided for addressing issues related to water management in electrochemical cells and other devices employing the diffusion media. In accordance with one embodiment of the present invention, a process for fabricating a diffusion media is provided. A diffusion media substrate is provided comprising a porous fibrous matrix defining first and second major faces. The substrate comprises an amount of carbonaceous material sufficient to render the substrate electrically conductive. A mesoporous layer is applied along at least a portion of one of the first and second major faces of the substrate. The mesoporous layer is applied to the substrate by providing a coating comprising a hydrophobic component, a hydrophilic component, and a pore forming agent. The substrate is free of fluorinated polymers outside of regions of the substrate carrying the mesoporous layer. The pore forming agent is decomposed such that the mesoporous layer is more porous than the diffusion media substrate.

A solid polymer electrolyte composite membrane and method of manufacturing the same. According to one embodiment, the composite membrane comprises a thin, rigid, dimensionally-stable, non-electrically-conducting support, the support having a plurality of cylindrical, straight-through pores extending perpendicularly between opposing top and bottom surfaces of the support. The pores are unevenly distributed, with some or no pores located along the periphery and more pores located centrally. The pores are completely filled with a solid polymer electrolyte, the solid polymer electrolyte including a dispersed reduced noble metal or noble metal oxide. The solid polymer electrolyte may also be deposited over the top and/or bottom surfaces of the support.

Electrical devices having a plurality of stacked electrode layers are described. At least one of the electrode layers contains continuous fibers that are infused with carbon nanotubes. The continuous fibers can be disposed upon an electrically conductive base plate. The electrical devices can further contain an electrolyte contacting each electrode layer and a layer of separator material disposed between each electrode layer, in which case the electrical devices can form a supercapacitor. Such supercapacitors can have a capacitance of at least about 1 Farad/gram of continuous fibers. The capacitance can be increased by coating at least a portion of the infused carbon nanotubes with a material such as, for example, a conducting polymer, a main group metal compound, and/or a transition metal compound. Methods for producing the electrical devices are also described.

The invention relates to the new usage of puerarin in the field of pharmaceutical products, in other words, it relates to the application of puerarin in the preparation of drugs for P2X3 mediated pain/nervous system diseases. The experiment shows that puerarin can inhibit pain-related behavioral responses, subsequently immunohistochemical analysis, in situ hybridization, RT-PCR, protein blotting and other techniques were utilized to observe the inhibition of puerarin on mRNA and protein expression of P2X3 receptor in dorsal root ganglion of rats with neuropathic pain and in dorsal root ganglion and sensory nerve ending in the burn model of rats, it was found by using whole-cell patch clamp technique that puerarin can significantly reduce the electric current activated by P2X3 receptor agonist in the neuron of dorsal root ganglion of rats with neuropathic pain. The experiment proves that the mechanism for the inhibitory effects of puerarin on acute and chronic pain is to block the transmission of pain sense information that is mediated by P2X3 receptor in primary sensory neurons. The invention provides a kind of new method for the prevention and treatment on acute and chronic pain, and it also indicates that puerarin can act as a antagonist for P2X3 receptor, which will be helpful for the application of drugs in the prevention and treatment on P2X3 receptor involved nervous system diseases.
