TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The oxy-anion of molybdenum, tungsten, vanadium, phosphorus, and/or antimony comprises alkali metal, alkaline earth metal, ammonium, or amine salt of molybdate, tungstate, metatungstate, vanadate, metavanadate, ortho phosphate, pyrophosphate, hexametaphosphate, polyphosphate, phosphoric acid, antimony tartrates, antimonate, and/or hydroxyantimonate; an oxy-anion of phosphorus; and an oxy-anion of molybdenum, tungsten, vanadium, and/or antimony. The corrosion inhibitor comprises an azole-based corrosion inhibitor, a siloxane-based corrosion inhibitor, colloidal silica, silicate, carboxylate, tall oil fatty acid, borate, nitrate, nitrite, their alkali or alkaline earth metal salt, their ammonium salt, and/or their amine salt (preferably carboxylate selected from 5-24C aromatic and aliphatic, mono-, di- and tri carboxylic acids and/or carboxylic acid salts). Preferred Composition: The heat transfer fluid comprises the oxy-anion of molybdenum, tungsten, vanadium, phosphorus, and/or antimony (0.01-10 wt.%) (preferably oxy-anion of phosphorus (0.01-3 wt.%), and oxy-anion of molybdenum, tungsten, vanadium, and/or antimony (0.01-3 wt.%)). The additive package comprises the oxy-anion of molybdenum, tungsten, vanadium, phosphorus, and/or antimony (1-99 wt.%), and the corrosion inhibitor (1-99 wt.%), where the additive package is free of liquid coolants.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Composition: The liquid coolant comprises water (0.1-90 wt.%), and alcohol (1-99.9 wt.%). The heat transfer system further comprises a colorant, antifoam agent, wetting agent, biocide, bitterant, and/or dispersant. Preferred Components: The liquid coolant comprises an alcohol, and/or water. The alcohol comprises monohydric alcohols and/or polyhydric alcohols (preferably methanol, ethanol, propanol, butanol, furfural, tetrahydro fur fury 1 alcohol, ethoxylated furfuryl alcohol, alkoxy alkanol, ethylene glycol, diethylene glycol, Methylene glycol, 1,2-propylene glycol, 1,3-propylene glycol, dipropylene glycol, butylene glycol, glycerol, glycerol-l,2-dimethyl ether, glycerol-1,3 dimethyl ether, monoethylether of glycerol, sorbitol, 1,2,6-hexanetriol, and/or trimethylol propane).
