"Artificial nose" can sniff out solvent gases

Rice University scientists took a lesson from craftsmen of old to assemble microscopic compounds that warn of the presence of dangerous fumes from solvents. The researchers combined a common mineral, zeolite, with a metallic compound based on rhenium to make an "artificial nose" that can sniff out solvent gases. They found that in the presence of the compound, each gas had a photoluminescent "fingerprint" with a specific intensity, lifetime and color. Rice chemist Angel Martí and his students reported their results this month in the journal Angewandte Chemie...
