Rukmini quenched her thirst with the Ganges water. The excess of boron trichloride was quenched in a mixture of potassium carbonate and methanol. These alloys become softer than normal when quenched, and then harden over time. Thirst is listed as "Quenched", "Normal", "Thirsty", and "Parched". Most applications require that quenched parts be tempered. Doxorubicin fluorescence is quenched by binding to DNA, and shielded by micelle encapsulation. These are fully quenched to martensite during processing. Researchers are seeking to design polymers whose fluorescence is quenched when they encounter specific molecules. The furnace effluent is immediately quenched with cold EDC to stop undesirable side reactions. Singlet oxygen can be quenched by metal chelates, with nickel phenolates being a common example. Note that independent of the material the bolt is quenched and tempered. The iminium ion is then quenched by reaction with a nucleophile. A frit is a ceramic composition that has been fused, quenched, and granulated. Once the rock was heated by fire it was quenched with water to break it. The reaction is quenched with acid.
