President Barack Obama's pursuit of energy independence promises to accelerate research and development for alternative energy sources -- solar, wind and geothermal power, biofuels, hydrogen and biomass, to name a few. For the hydrogen economy, one of the roadblocks to success is the hydrogen itself. Hydrogen needs to be purified before it can be used as fuel for fuel cells, but current methods are not very clean or efficient. Northwestern University chemist Mercouri G. Kanatzidis, together...

By Gu, April Z Saunders, A; Neethling, J B; Stensel, H D; Blackall, L L ABSTRACT: The abundance and relevance of Accumulibacter phosphatis (presumed to be polyphosphate-accumulating organisms [PAOs]), Competibacter phosphatis (presumed to be glycogen- accumulating organisms [GAOs]), and tetrad-forming organisms (TFOs) to phosphorus removal performance at six full-scale enhanced biological phosphorus removal (EBPR) wastewater treatment plants were investigated. Coexistence of various levels...

By Robert Salonga MARTINEZ -- A sulfur spill early this morning on the Marina Vista on-ramp to southbound Interstate 680 did not pose a health hazard and was left to dissipate, the California Highway Patrol and a county hazardous materials official said. The spill, reported at the Marina Vista Avenue on-ramp about 6:40 a.m., came from a truck operated by Silva Trucking, of French Camp. The chemical involved was molten sulfur, which solidified on the roadway. Shell Oil contracted with...

By JOANN LOVIGLIO By Joann Loviglio The Associated Press PHILADELPHIA For anyone whose last foray into chemistry was being forced to memorize the periodic table of elements in high school, there's new reason to take another look at a subject you may have vowed never to revisit after final exams. As chemical and molecular innovations - from nylon to plastic to cosmetics - transformed modern life, genomics and nanotechnology discoveries could dramatically transform the future. The...

NSF-funded Chemical Bonding Center project provides a new approach for harnessing the sun's energy With the assistance of a five-year $20 million award from the National Science Foundation (NSF), the California Institute of Technology (Caltech) Chemical Bonding Center (CBC) project, called "Powering the Planet," will increase the number of its collaborators to fulfill its goal of efficiently and economically converting solar energy and water into hydrogen and oxygen fuels. The hydrogen and...

Researchers have discovered an unusual molecule that is essential to the atmosphere's ability to break down pollutants, especially the compounds that cause acid rain. It's the unusual chemistry facilitated by this molecule, however, that will attract the most attention from scientists. Marsha Lester, the University of Pennsylvania's Edmund J. Kahn Distinguished Professor, and Joseph Francisco, William E. Moore Distinguished Professor of Chemistry at Purdue University, found the molecule,...

A strange, metal brew lies buried deep within Jupiter and Saturn, according to a new study by researchers at the University of California, Berkeley, and in London. The study, published in this week's online edition of the journal Proceedings of the National Academy of Sciences, demonstrates that metallic helium is less rare than was previously thought and is produced under the kinds of conditions present at the centers of giant, gaseous planets, mixing with metal hydrogen and forming a liquid...

By Ken Ward Jr. A federal judge has sealed from public view documents about a coal company's efforts to clean up selenium pollution from a mountaintop removal mine in Logan County. U.S. District Judge Robert C. Chambers last week granted Apogee Coal Co.'s motion to file the documents under seal. Chambers sealed four documents containing reports from consulting firms that Apogee is considering hiring to design or install selenium treatment equipment at its mining operation. A...

By SHILLINGTON, David Combustion has become widely-researched and highly-effective process, but what is it doing to the environment? ------------------ -- Combustion processes (including wood burning) have been extensively researched, particularly since the advent of the internal combustion engine and the development of the aerospace industry. As a result motor cars of today are far more fuel efficient. The term combustion is used to describe the process whereby a fuel source is oxidised...

Acid Rain
2013-04-01 10:21:17

Acid rain is any form of precipitation that is unusually acidic, meaning that is possesses high levels of hydrogen ions. It can have harmful effects on aquatic animals, plants, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules within the atmosphere to produce acids. Nitrogen oxides can be produced naturally by lightening strikes. Sulfur dioxide can be produced naturally by volcanic eruptions. The chemicals that are...
