US Patent:

20090000194, Jan 1, 2009

Filed:

Jan 12, 2007

Appl. No.:

12/160803

Inventors:

Puneet Gupta - Houston TX, US
Luis Gilberto Velazquez Vargas - Columbus OH, US
Fanxing Li - Columbus OH, US

International Classification:

C10J 1/20

US Classification:

48199 R, 502102, 501 94

Abstract:

Systems and methods for converting fuel are provided wherein the system comprises at least reactors configured to conduct oxidation-reduction reactions. The first reactor comprises a plurality of ceramic composite particles, wherein the ceramic composite particles comprises at least one metal oxide disposed on a support. The first reactor is configured to reduce the least one metal oxide with a fuel to produce a reduced metal or a reduced metal oxide. The second reactor is configured to oxidize the reduced metal or reduced metal oxide to produce a metal oxide intermediate. The system may also comprise a third reactor configured to oxidize the metal oxide intermediate to regenerate the metal oxide of the ceramic composite particles.

Appl. No.:

16/838249

Inventors:

- Woburn MA, US
Miguel Camargo Soto - Mexicali, MX
Luis Enrique Velazquez Cardenas - Agoura Hills CA, US

International Classification:

B23K 26/36
H01L 21/82
H01L 21/302

Abstract:

A method for separating integrated circuit dies from a wafer includes making at least two cutting passes with a laser along a first die street of an integrated circuit die, the first die street extending along a first axis on the wafer. The method also includes making at least two cutting passes with the laser along a second die street of the integrated circuit die, the second die street extending along a second axis on the wafer that is generally perpendicular to the first axis. In one process, three cutting passes are made with the laser alternatingly along the first and second die streets to separate the integrated die circuit along the first and second axes. In another process, two cutting passes are made with the laser along the first die street in opposite directions, and two cutting passes are then made with the laser along the second die street in opposite directions.

Appl. No.:

14/091654

Inventors:

- Columbus OH, US
Puneet Gupta - Houston TX, US
Luis Gilberto Velazquez Vargas - Columbus OH, US
Fanxing Li - Columbus OH, US

Assignee:

The Ohio State University - Columbus OH

International Classification:

C10J 3/82

US Classification:

48210

Abstract:

A method for converting fuel may include reducing at least one metal oxide in a first reactor with a fuel to produce a reduced metal or a reduced metal oxide, transporting the reduced metal or reduced metal oxide from the first reactor to a second reactor, oxidizing at least a portion of the reduced metal or reduced metal oxide from the first reactor in the second reactor to produce a metal oxide intermediate, transporting the metal oxide intermediate from the second reactor to a third reactor, removing ash, char, or unwanted materials with a separation unit from the metal oxide intermediate transported from the second reactor to the third reactor, regenerating the at least one metal oxide, and transporting the regenerated metal oxide from the third reactor to the first reactor.
