A new Pacific Northwest National Laboratory study offers the most detailed picture to date on how oxygen can be made in frigid reaches far from Earth ATLANTA-- Some may be surprised to learn that bleach-blondes and the enabler of life elsewhere in our solar system have something in common. And, no, it's not intelligence. It is, in fact, hydrogen peroxide. But how that hydrogen peroxide emerges from ice to become life-sustaining oxygen has been unclear. Now, a new study at the Department of...

Many advanced material fabrication techniques use multi-step processes that can be environmentally stressing, energy-consuming and have high-costs. In an article published in AZojomo* researchers have described a novel method called "Localized Hydrothermal Technique" for growing coatings of barium titanate or other complex oxides on titanium. In this method, thin films grow on transition metal substrates by Joule heating of the substrate while it is immersed in an aqueous alkali-earth...

A number of hypotheses have been used to explain how free oxygen first accumulated in Earth's atmosphere some 2.4 billion years ago, but a full understanding has proven elusive. Now a new model offers plausible scenarios for how oxygen came to dominate the atmosphere, and why it took at least 300 million years after bacterial photosynthesis started producing oxygen in large quantities. The big reason for the long delay was that processes such as volcanic gas production acted as sinks to...

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...
