  • New Fingerprinting Method Tracks Mercury in Environment

    ANN ARBOR, Mich.—With mercury polluting our air, soil and water and becoming concentrated in fish and wildlife as it is passed up the food chain, understanding how the potent nerve toxin travels through the environment is crucial. A new method developed at the University of Michigan uses natural "fingerprints" to track mercury and the chemical transformations it undergoes. A report on the work is published today in Science Express. >> Read the Full Article

  • Platinum-free fuel cell developed in Japan

    TOKYO (Reuters) - Japan's Daihatsu Motor Co Ltd said on Friday it has developed a technology to make fuel cells without platinum, the precious metal used in the electrolyte process in existing hydrogen-based fuel cells. By using alkali, instead of acid, anion exchange membranes, Daihatsu's fuel cell can work with less costly metals which are less resistant to corrosion than platinum, such as cobalt or nickel, Daihatsu said in a statement. >> Read the Full Article
