International Classification:

H01L 31/12

US Classification:

257 84, 257184, 257186, 257438, 257440, 257603, 257605, 257606, 257E29335, 257E31063, 257E31064

Abstract:

Apparatuses and systems for photon detection can include a first optical sensing structure structured to absorb light at a first optical wavelength; and a second optical sensing structure engaged with the first optical sensing structure to allow optical communication between the first and the second optical sensing structures. The second optical sensing structure can be structured to absorb light at a second optical wavelength longer than the first optical wavelength and to emit light at the first optical wavelength which is absorbed by the first optical sensing structure. Apparatuses and systems can include a bandgap grading region.

Appl. No.:

15/731032

Inventors:

JAMES CHIN CHENG YANG - HOUSTON TX, US

International Classification:

C05F 11/06

Abstract:

The present invention utilizes a high-speed intensive mixer in fluidizing type solid phase neutralization reactor to blend solid state alkali hydroxide with any humic acid sources. The final product is a dry humic acid salt. The purpose of this innovative method is to eliminate a series of complicated unit operations commonly employed by the traditional process. These removed steps may include dissolving caustic soda, mixing in a paste like formation, extrusion, granulation, drying, and grinding, etc. The new invention contributes to a simplified flowsheet, resulting in sharply reduced equipment investment, the required plant space, and labor and energy costs. All these factors coupled with increased productivity will drastically lower the overall production cost. Also the reduction of dust pollution will greatly minimize the impact in environmental protection and safety issues.
