Improved Gas Filling and Sealing of an HC-PCF
new!
|
|
Date added: 09/01/2008 |
|
An improved packaging approach has been devised for filling a hollow-core photonic-crystal fiber (HC-PCF) with a gas, sealing the HC-PCF to retain the gas, and providing for optical connections and, optionally, a plumbing fitting for changing or augmenting the gas filling. |

|
Date added: 09/01/2008 |
|
Assembling large numbers of nanoscale structures in predetermined ways is notoriously difficult, and is a very important problem in current technologies involving
carbon nanotubes and other nanoscale materials. Using fluids to control the patterning and arrangement of nanoscale objects offers a promising solution. |

Fabricating Large-Area Sheets of Single-Layer Graphene by CVD
hot!
|
|
Date added: 08/01/2008 |
|
A set of methods has been developed for producing large area domains of graphene, which can be used as starting materials for lithographic fabrication of graphene-based
electronics. These methods are all variations on the idea of producing graphene by chemical vapor deposition. |

Fabricating High-Resolution X-Ray Collimators
hot!
|
|
Date added: 05/01/2008 |
|
A process and method for fabricating high-resolution x-ray collimators involve photochemical machining and precision stack lamination. Special fixturing and etching techniques have been developed that allow higher resolution multi-grid collimators to be fabricated. |

Vacuum Packaging of MEMS With Multiple Internal Seal Rings
hot!
|
|
Date added: 02/01/2008 |
|
The Multiple Internal Seal Ring (MISR) MEMS vacuum package design eliminates the need for electrical lines running beneath the seal ring and thus eliminates the resulting
vacuum leaks and/or planarization step costs. |

Patterning of Indium Tin Oxide Films
hot!
|
|
Date added: 01/02/2008 |
|
The author has developed a rapid, economical, hazzard-free alternative for paterning indiun tin oxide (ITO) on polyester films that involves readily accessible equipment and chemicals. The process involves equipment that totals less than $500 and can produce patterned ITO films on polyester in less than 1 hour. |

Electrophoretic Deposition on Porous Non-Conductors
hot!
|
|
Date added: 11/01/2007 |
|
The process does not necessitate the need for any heat treatment under reducing atmosphere or use of any conductive coating. The deposition has been made possible simply through the use of adequately porous substrates to ensure the presence of a conductiong path of solvent during EDP. |
