The present invention also includes dilithiated forms of these compounds, lithium and lithium-ion secondary batteries using these compounds as positive electrode materials, and methods of preparing these compounds.

Abstract: A process is disclosed for converting low reactive fly ash to a highly reactive pozzolanic material by heating the fly ash until at least a portion of the fly ash melts; then rapidly cooling the fly ash. The resulting vitrified fly ash has improved cementitious properties relative to untreated fly ash.

Abstract: The present invention is a method for the detoxification and/or chemical remediation of soil contaminated with volatile organic compounds. The process comprises treating the soil with the sodium and calcium salts of naphthalene sulfonates, lignosulfonates, their derivatives and mixtures thereof. The volatile organics are then forced from the soil as the soil is more attracted to the admixture than it is to the volatile organic contaminants.
