Research gives new perspective on periodic table Transforming lead into gold is an impossible feat, but a similar type of "alchemy" is not only possible, but cost-effective too. Three Penn State researchers have shown that certain combinations of elemental atoms have electronic signatures that mimic the electronic signatures of other elements. According to the team's leader A. Welford Castleman Jr., Eberly Distinguished Chair in Science and Evan Pugh Professor in the Departments of Chemistry...

Fierce competition over raw materials for new green technologies could become a thing of the past, thanks to a discovery by scientists from the University of Leeds. Researchers from Leeds' Faculty of Engineering have discovered how to recover significant quantities of rare-earth oxides, present in titanium dioxide minerals. The rare-earth oxides, which are indispensable for the manufacture of wind turbines, energy-efficient lighting, and hybrid and electric cars, are extracted or reclaimed...

A species of bacteria, isolated from sediments deep under the Pacific Ocean, could provide a powerful clean-up tool for heavy metal pollution. Writing in the current issue of the journal, Microbiology, Professor Gejiao Wang and his colleagues from Huazhong Agricultural University in Wuhan, PR China describe how a particular strain of Brachybacterium, strain Mn32, proved to be highly effective in removing manganese from solutions, converting it into insoluble manganese oxides. Not only did the...

An international team of geologists may have uncovered the answer to an age-old question - an ice-age-old question, that is. It appears that Earth's earliest ice age may have been due to the rise of oxygen in Earth's atmosphere, which consumed atmospheric greenhouse gases and chilled the earth. Alan J. Kaufman, professor of geology at the University of Maryland, Maryland geology colleague James Farquhar, and scientists from Germany, South Africa, Canada, and the U.S.A., uncovered evidence...

The Earth's original atmosphere held very little oxygen. This began to change around 2.4 billion years ago when oxygen levels increased dramatically during what scientists call the "Great Oxidation Event." The cause of this event has puzzled scientists, but researchers writing in Nature have found indications in ancient sedimentary rocks that it may have been linked to a drop in the level of dissolved nickel in seawater. "The Great Oxidation Event is what irreversibly changed surface...

Red jasper cored from layers 3.46 billion years old suggests that not only did the oceans contain abundant oxygen then, but that the atmosphere was as oxygen rich as it is today, according to geologists. This jasper or hematite-rich chert formed in ways similar to the way this rock forms around hydrothermal vents in the deep oceans today. "Many people have assumed that the hematite in ancient rocks formed by the oxidation of siderite in the modern atmosphere," said Hiroshi Ohmoto, professor...

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...
