New analyses of more than 4,000 scientific studies have concluded that a family of "miracle materials" called MOFs have a bright future in products and technologies – ranging from the fuel tanks in hydrogen-powered cars to muting the effects of the greenhouse gas carbon dioxide – that are critical for solving some of the greatest global challenges of the 21st century. The 18 articles examining 4,283 pieces of research on MOFs published in the past appear in a special edition of...

New method removes discovery bottleneck by identifying materials with promise Porous crystals called metal-organic frameworks, with their nanoscopic pores and incredibly high surface areas, are excellent materials for natural gas storage. But with millions of different structures possible, where does one focus? A Northwestern University research team has developed a computational method that can save scientists and engineers valuable time in the discovery process. The new algorithm...

Compounds made from renewable materials could be used for gas storage, food technologies Sugar, salt, alcohol and a little serendipity led a Northwestern University research team to discover a new class of nanostructures that could be used for gas storage and food and medical technologies. And the compounds are edible. The porous crystals are the first known all-natural metal-organic frameworks (MOFs) that are simple to make. Most other MOFs are made from petroleum-based ingredients, but the...

Chemists from UCLA and South Korea report the "ultimate porosity of a nano-material," achieving world records for both porosity and carbon dioxide storage capacity in an important class of materials known as MOFs, or metal"“organic frameworks. MOFs, sometimes described as crystal sponges, have pores "” openings on the nanoscale which can store gases that are usually difficult to store and transport. Porosity is crucial for compacting large amounts of gases into small volumes and...

UCLA chemists report creating a synthetic "gene" that could capture heat-trapping carbon dioxide emissions, which contribute to global warming, rising sea levels and the increased acidity of oceans. The research appears in the Feb. 12 issue of the journal Science. "We created three-dimensional, synthetic DNA-like crystals," said UCLA chemistry and biochemistry professor Omar M. Yaghi, who is a member of the California NanoSystems Institute (CNSI) at UCLA and the UCLA"“Department of...

ANN ARBOR, Mich.--- Since the Industrial Revolution, levels of carbon dioxide---a major contributor to the greenhouse effect---have been on the rise, prompting scientists to search for ways of counteracting the trend. One of the main strategies is removing carbon dioxide (CO2) from the flue exhaust of power plants, using porous materials that take up the gas as it travels up the flue. A new class of materials invented and developed by Omar Yaghi at the University of Michigan can store vast...
