Filed:

Sep 21, 2004

Appl. No.:

10/946025

Inventors:

D. Wayne Cooke - Santa Fe NM, US
Bryan L. Bennett - Los Alamos NM, US
Ross E. Muenchausen - Los Alamos NM, US
Debra A. Wrobleski - Los Alamos NM, US
Edward B. Orler - Los Alamos NM, US

Assignee:

Los Alamos National Security, LLC - Los Alamos NM

International Classification:

C09K 11/08

US Classification:

250361R

Abstract:

A flexible composite scintillator was prepared by mixing fast, bright, dense rare-earth doped powdered oxyorthosilicate (such as LSO:Ce, LSO:Sm, and GSO:Ce) scintillator with a polymer binder. The binder is transparent to the scintillator emission. The composite is seamless and can be made large and in a wide variety of shapes. Importantly, the composite can be tailored to emit light in a spectral region that matches the optimum response of photomultipliers (about 400 nanometers) or photodiodes (about 600 nanometers), which maximizes the overall detector efficiency.

Abstract:

A stabilized non-conductive polyaniline solution comprising from about 1 to bout 10 percent by weight polyaniline or a polyaniline derivative, from about 90 to about 99 percent by weight N-methylpyrrolidone, and from about 0. 5 percent by weight to about 15 percent by weight of a solution stabilizing additive selected from the group consisting of hindered amine light stabilizers, polymeric amines, and dialkylamines, percent by weight of additive based on the total weight of polyaniline or polyaniline derivative is provided together with a method for stabilizing a polyaniline solution.

Appl. No.:

8/806894

Inventors:

Donald J. Rej - Los Alamos NM
Debra A. Wrobleski - Los Alamos NM

Assignee:

The Regents of the University of California - Los Alamos NM

International Classification:

A62D 3100
G03C 100

US Classification:

252478

Abstract:

A precursor composition adapted for neutron capture induced radiation treatment of said precursor composition including a polymer matrix containing dispersed dopant material, the dispersed dopant material characterized as capable of neutron capture whereupon subsequent in situ energetic ion irradiation of the polymer matrix can occur, and further characterized as dispersed so as to provide dopant domain sizes significantly less than the energetic ion range of the dopant material is provided. Also provided is a process of in situ irradiation of bulk polymeric articles by first providing a precursor composition adapted for neutron capture induced radiation treatment of the precursor composition including a polymer matrix containing dispersed dopant material, the dispersed dopant material characterized as dispersed so as to provide dopant domain sizes significantly less than the energetic ion range of the dopant material, and then exposing the precursor composition to a source of neutrons.

US Classification:

428213

Abstract:

A method of protecting a metal substrate from corrosion including coating a metal substrate of, e. g. , steel, iron or aluminum, with a conductive polymer layer of, e. g. , polyaniline, coating upon said metal substrate, and coating the conductive polymer-coated metal substrate with a layer of a topcoat upon the conductive polymer coating layer, is provided, together with the resultant coated article from said method.
