Thus, highly\n active and selective catalysts as well as adsorbents and ion exchangers\n with high capacities and selectivities were developed. In the petroleum\n refining and petrochemical industries, zeolites have made possible\n cheaper and lead-free gasoline, higher performance and lower-cost\n synthetic fibers and plastics, and many improvements in process\n efficiency and quality and in performance. Zeolites also help protect\n the environment by improving energy efficiency, reducing automobile\n exhaust and other emissions, cleaning up hazardous wastes (including\n the Three Mile Island nuclear power plant and other radioactive\n wastes), and, as specially tailored desiccants, facilitating the\n substitution of new refrigerants for the ozone-depleting\n chlorofluorocarbons banned by the Montreal Protocol.<\/jats:p>","DOI":"10.1073\/pnas.96.7.3471","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T10:42:40Z","timestamp":1027680160000},"page":"3471-3478","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":247,"title":["Synthetic zeolites and other microporous oxide molecular sieves"],"prefix":"10.1073","volume":"96","author":[{"given":"John D.","family":"Sherman","sequence":"first","affiliation":[{"name":"Research and Development Department, UOP LLC, 25 East Algonquin\r Road, Des Plaines, IL 60017-5017"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[1999,3,30]]},"reference":[{"key":"e_1_3_3_1_2","doi-asserted-by":"crossref","first-page":"279","DOI":"10.1021\/ba-1971-0101.ch022","volume":"101","author":"Sheppard R A","year":"1971","unstructured":"R A Sheppard Adv Chem Ser 101, 279\u2013310 (1971).","journal-title":"Adv Chem Ser"},{"key":"e_1_3_3_2_2","first-page":"71","volume-title":"Molecular Sieves","author":"Sand L B","year":"1968","unstructured":"L B Sand Molecular Sieves (Soc. of Chem.
