    摘要： Nozzle Assemblies and methods of use for producing a liquid jet are disclosed that may be permit adjustable time delays between mixing of fluids and observation of reactions. An example nozzle assembly includes: a housing having an inlet and an outlet and a first channel defined therebetween, where the housing includes a gas focusing aperture defining the housing outlet; an intermediate tube disposed within the first channel of the housing, where the intermediate tube has an inlet and an outlet and defines a second channel therebetween; and a central tube disposed within the second channel of the intermediate tube, where the central tube has an inlet and an outlet and defines a third channel therebetween, where the central tube outlet is longitudinally spaced apart from the intermediate tube outlet such that the intermediate tube outlet is disposed between the central tube outlet and the gas focusing aperture's inlet.

    摘要： A nanomachining method for producing high-aspect ratio precise nanostructures. The method begins by irradiating a wafer with an energetic charged-particle beam. Next, a layer of patterning material is deposited on one side of the wafer and a layer of etch stop or metal plating base is coated on the other side of the wafer. A desired pattern is generated in the patterning material on the top surface of the irradiated wafer using conventional electron-beam lithography techniques. Lastly, the wafer is placed in an appropriate chemical solution that produces a directional etch of the wafer only in the area from which the resist has been removed by the patterning process. The high mechanical strength of the wafer materials compared to the organic resists used in conventional lithography techniques with allows the transfer of the precise patterns into structures with aspect ratios much larger than those previously achievable.

    摘要： An optical phase plate system and method for enhancing phase contrast in electron beam imaging includes a transmission electron microscope (TEM) having a back focal plane; an optical cavity having a high internal surface reflectance, the center of the optical cavity located at the back focal plane of the TEM, the optical cavity having first and second ports arranged oppositely along a symmetrical axis of the optical cavity to admit an electron beam provided by the TEM through the first port to pass through and focus at the center of the optical cavity, and to exit through the second port, and wherein the optical cavity further has an optical port on an axis transverse to and intersecting the electron beam axis to admit a laser beam; a laser coupled to the optical cavity to provide a laser beam of a selected wavelength to enter the optical cavity through the optical port, wherein the laser beam is multiply reflected from the high internal surface reflectance to provide a high intensity standing wave optical phase plate focused at the back focal plane of the TEM to cause a modulation of the electron beam; and an image plane of the TEM placed opposite the second port of the optical cavity to receive the electron beam modulated by the high intensity standing wave optical phase plate.

    摘要： The improved bandwidth provisioning solution of the present invention enables the provision of bandwidth on demand by dynamically establishing and terminating one or more dynamic virtual circuits (SVCs) (137) to supplement a subscriber's default broadband connection. The improved bandwidth provisioning solution includes a client-side application (107) residing on the subscriber's data processing system (105) and a connection-management application (142) residing on a proxy signaling server (140). The client-side application (107) transmits a subscriber's request for a bandwidth-on-demand session to the connection-management application (142), which communicates with an asynchronous transfer mode (ATM) edge device (120) using User Network Interface (UNI) signaling to initiate the one or more VCs (137). When the subscriber no longer desires the additional bandwidth, the supplemental VCs (137) may be terminated.
