摘要:
A laser device which may be used as an oscillator or amplifier comprising a chamber having a volume formed therein and a gain medium within the volume. The gain medium comprises solid-state elements containing active laser ion distributed within the volume. A cooling fluid flows about the solid-state elements and a semiconductor laser diode provides optical pump radiation into the volume of the laser chamber such that laser emission from the device passes through the gain medium and the fluid. The laser device provides the advantages of a solid-state gain medium laser (e.g., diode-pumping, high power density, etc), but enables operation at higher average power and beam quality than would be achievable from a pure solid-state medium.

A reflective reticle substantially reduces or eliminates pattern distortion that results from the absorption of EUV radiation while maintaining a reticle thickness consistent with industry standards. The reflective reticle includes a layer of ultra-low expansion (ULE) glass and a substrate of Cordierite having a thermal conductivity substantially larger than that of ULE glass. An aluminum layer is disposed onto a first surface of the ULE glass and a second surface of the ULE glass is polished to be substantially flat and defect-free. The Cordierite substrate can be directly bonded to the aluminum layer using anodic bonding to form the reflective reticle. Alternatively, a first surface of an intermediate Zerodur layer can be bonded to the aluminum layer, and a second aluminum layer can be used to anodically bond the Cordierite substrate to a second surface of the Zerodur layer, thereby forming the reflective reticle.

The invention is a hydrogen passivation shut down system for a fuel cell power plant (10). An anode flow path (24) is in fluid communication with an anode catalyst (14) for directing hydrogen fuel to flow adjacent to the anode catalyst (14), and a cathode flow path (38) is in fluid communication with a cathode catalyst (16) for directing an oxidant to flow adjacent to the cathode catalyst (16) of a fuel cell (12). Hydrogen fuel is permitted to transfer between the anode flow path (24) and the cathode flow path (38). A hydrogen reservoir (66) is secured in fluid communication with the anode flow path (24) for receiving and storing hydrogen during fuel cell (12) operation, and for releasing the hydrogen into the fuel cell (12) whenever the fuel cell (12) is shut down.
摘要:
A vegetation pod for creating a green roof is disclosed. The vegetation pod includes vegetation that absorbs and stores water. The roots of the vegetation grow in a growing media that rests atop a layer of filter fabric. The filter fabric is disposed within a tray that is easily handled by an installer. The tray includes a fastening mechanism that couples multiple trays together. An additional layer of absorbent material may be provided between the filter fabric and the tray. A second, preferably larger tray may be provided for accommodating a series of smaller trays. An additional layer of filter fabric may be provided between the trays.

摘要:
Microparticle-based analytical methods, systems and applications are provided. Specifically, the use of resonant resonant light scattering as an analytical method for determining either or both a particle's identity and the presence and optionally, the concentration of one or more particular target analytes is described. Applications of these microparticle-based methods in biological and chemical assays are also disclosed.

A freeze tolerant fuel cell power plant (10) includes at least one fuel cell (12), a coolant loop (18) including a freeze tolerant accumulator (22) for storing and separating a water immiscible fluid and water coolant, a direct contact heat exchanger (56) for mixing the water immiscible fluid and the water coolant within a mixing region (72) of the heat exchanger (56), a coolant pump (21) for circulating the coolant through the coolant loop (18), a radiator loop (84) for circulating the water immiscible fluid through the heat exchanger (56), and a radiator (86) for removing heat from the coolant. The plant (10) utilizes the water immiscible fluid during steady-state operation to cool the fuel cell and during shut down of the plant to displace water from the fuel cell (12) to the freeze tolerant accumulator (22).
