Filed:

Oct 25, 2007

Appl. No.:

11/924136

Inventors:

Edward Allen McKigney - Los Alamos NM, US
Anthony Keiran Burrell - Los Alamos NM, US
Bryan L. Bennett - Los Alamos NM, US
David Wayne Cooke - Santa Fe NM, US
Kevin Curtis Ott - Los Alamos NM, US
Minesh Kantilal Bacrania - Los Alamos NM, US

Assignee:

Los Alamos National Security, LLC - Los Alamos NM

International Classification:

G01T 1/20

US Classification:

250361R

Abstract:

An improved nanophosphor scintillator liquid comprises nanophosphor particles in a liquid matrix. The nanophosphor particles are optionally surface modified with an organic ligand. The surface modified nanophosphor particle is essentially surface charge neutral, thereby preventing agglomeration of the nanophosphor particles during dispersion in a liquid scintillator matrix. The improved nanophosphor scintillator liquid may be used in any conventional liquid scintillator application, including in a radiation detector.

Abstract:

An improved nanophosphor composite comprises surface modified nanophosphor particles in a solid matrix. The nanophosphor particle surface is modified with an organic ligand, or by covalently bonding a polymeric or polymeric precursor material. The surface modified nanophosphor particle is essentially charge neutral, thereby preventing agglomeration of the nanophosphor particles during formation of the composite material. The improved nanophosphor composite may be used in any conventional scintillator application, including in a radiation detector.

E21B 33/14
E21B 47/005

Abstract:

Embodiments of the disclosure include swellable smart gel sealants and methods of using smart gel sealants. In certain embodiments, the smart gel sealants reversibly swell when exposed to a certain trigger, such as carbonic acid and/or sulfuric acid. In specific embodiments, the smart gel is comprised within a cement composition.

International Classification:

E21B 33/138
C09K 8/42
C09K 8/44

Abstract:

Embodiments of the disclosure include swellable smart gel sealants and methods of using smart gel sealants. In certain embodiments, the smart gel sealants reversibly swell when exposed to a certain trigger, such as temperature or pH. In specific embodiments, the smart gel is disposed within voids in a well and triggered to swell in order to seal the voids. One application of the smart gel sealant is to seal the casing of a well against the leakage of gas, such as HS.
