A method of determining total organofluorine in a sample comprising PFAS, comprising: providing a solution of PFAS in an organic solvent to obtain extracted PFAS, or extracting a sample with an organic solvent to obtain extracted PFAS; treating the extracted PFAS with a sodium metal dispersion and alcohol to obtain sodium fluoride; and quantifying the amount of the fluoride. Surprisingly, we discovered that the method recovered substantial fluorine from PFAS and significantly higher yields obtained by selection of the appropriate alcohols. The method is selective for organofluorine from inorganic fluorine.

A self-glowing solid material comprises a man-made metal mixture containing at least one rare earth metal and an oxide of iron. The material is inducible by flame initiation to self-glow with yellow-to-red colors (577-to-700 nanometer wavelengths). A stealth tracer ammunition comprises a projectile body having a tip and a base, and a solid pellet disposed in the base. The pellet may be made from the above-mentioned self-glowing solid material or another suitable material. The pellet becomes incandescent as a result of being heated when the ammunition is fired. The incandescent pellet emits a glow observable only from behind when the ammunition travels downrange after being fired. An illuminant comprises a bimodal blend of a man-made metal mixture containing at least one rare earth metal and an oxide of iron. The bimodal blend is a blend of smaller-sized fragments and larger-sized pellets. The illuminant is capable of ignition and dispersion in response to ballistic energy to create illumination. An illumination device comprises a body having an interior cavity, the body configured to be launched as a projectile or configured to contain projectiles. An illuminant is disposed in the cavity, the illuminant comprising a bimodal blend of a suitable illuminant material. The illuminant is capable of ignition and dispersion in response to ballistic energy to create illumination.

A method of making CNT films is described in which the film is washed with a mild acid treatment. The method generates a CNT film that is not sensitive to moisture or fluctuations in moisture. The method involves the use of anionic polysaccharides or anionic glycosaminoglycans such as hyaluronic acid, sodium salt, as aqueous dispersing agents and their modification to a hydrophobic matrix after deposition. In the course of conducting the work described here, we made the surprising discovery that washing with an aqueous acidic solution resulted in a decrease in resistance through the material. The invention also includes CNT composites made by the inventive methods and a CNT composite comprising CNTs and anionic polysaccharides or anionic glycosaminoglycans further characterized by a low cationic content and a high conductivity and/or small CNT particle size as measured by SEM.

A novel method of forming thin films of carbon nanotubes (CNTs) is described. In this method, carbon nanotubes are dispersed in a superacid solution and laid down on a substrate to form a conductive and transparent CNT network film. The superacid, in its deprotonated state, is an anion that has a permanent dipole moment. The superacid solution may be a pure superacid or have additional solvent. Preferably, the superacid solution does not contain an oxidizing agent. Novel, highly conductive and transparent CNT network films are also described.

Ferrate(VI)-containing compositions and methods of using ferrate(VI)

An undivided electrochemical cell. The electrochemical cell includes a housing defining an undivided chamber, the housing having one electrolyte inlet and at least two electrolyte outlets; an anode in the chamber; a cathode in the chamber; and an electrolyte in the chamber, wherein the anode and the cathode are not gas diffusion electrodes. The invention also involves a method of operating an electrochemical cell, and methods for making ferrate(VI).

Method for producing ferrate (V) and/or (VI)

Method and composition for decomposing and detoxifying chemical warfare agents, organic toxic compounds (e.g., pesticides), and for removal of contaminants in materials including fuels. The method and composition are based on ferrate (VI). The ferrate is typically applied to a contaminated surface or volume with a phase transfer catalyst and/or with a carrier.

A vaccine for in ovo vaccination against avian coccidiosis produced by a method including obtaining the coccidial oocysts from a fecal suspension, homogenizing the fecal suspension, separating the oocysts from the fecal debris by either salt flotation using sodium sulfate or gas flotation using air, sporulating the oocysts using hydrogen peroxide and air sparging, bleaching the sporulated oocysts, washing the bleached oocysts, concentrating the sterile washed oocysts and combining the concentrates of various species of coccidial oocysts, and producing a vaccine. The method in whole or in part can be applied to other kinds of encysted protozoa to produce vaccines for various types of animals.
