Researchers Identify Key Intermediate Steps In Artificial Photosynthesis Reaction
2014-03-04 11:03:17

Lynn Yarris, Berkeley Lab Artificial photosynthesis, in which we emulate the process used by nature to capture energy from the sun and convert it into electrochemical energy, is expected to be a major asset in any sustainable energy portfolio for the future. Artificial photosynthesis offers the promise of producing liquid fuels that are renewable and can be used without exacerbating global climate change. A key to realizing commercial-scale artificial photosynthesis technology is the...

Amber Earth's Atmosphere
2013-11-18 12:37:00

Brett Smith for redOrbit.com - Your Universe Online Elevated levels of oxygen in the atmosphere may have caused dinosaurs, insects and other organisms to grow to gigantic sizes millions of years ago, according to prevailing theories. If a new study from scientists at the Universities of Kansas and Alberta is correct, then the atmosphere of the Cretaceous had a relatively low oxygen content – making the high-oxygen theories severely flawed. “We do not want to negate the influence...

Tungsten In Aquifer Groundwater Controlled By pH, Oxygen
2013-10-01 11:25:44

Kansas State University Two Kansas geologists are helping shed new light on how tungsten metal is leached from the sediment surrounding aquifers into the groundwater. The findings may have implications for human health. Tungsten is a naturally occurring metal that is primarily used for incandescent light bulb filaments, drill bits and an alternative to lead in bullets. Though it is thought to be nonhazardous to the environment and nontoxic to humans, it can be poisonous if ingested in...

Life-Bearing Oxygen Appeared On Earth Three Billion Years Ago
2013-09-26 07:19:54

April Flowers for redOrbit.com - Your Universe Online New research from the University of Copenhagen and University of British Columbia (UBC) has revealed that oxygen appeared 700 million years earlier than we previously thought. The findings, published in the journal Nature, raises new questions about the evolution of early life. The research team examined the chemical composition of three-billion-year-old soils from South Africa, which are the oldest soils on Earth. They found...

Researchers report discovery in Science about manganese in aquatic environments An often-overlooked form of manganese, an element critical to many life processes, is far more prevalent in ocean environments than previously known, according to a study led by University of Delaware researchers that was published this week in "Science." The discovery alters understanding of the chemistry that moves manganese and other elements, like oxygen and carbon, through the natural world. Manganese...

Manganese Oxidation Played Key Role In Formation Of Oxygen On Earth
2013-06-27 07:25:47

April Flowers for redOrbit.com - Your Universe Online Oxygen is a necessary component for the survival of most terrestrial life on Earth. The planet´s atmosphere, however, did not always contain this life-sustaining substance. How and when oxygenic photosynthesis — the process responsible for producing oxygen on Earth through the splitting of water molecules — first began has been considered one of the great science mysteries of our planet. A new study, led by...

New Type Of Nanoscavenger Could Bring Next Generation Water Purification
2013-05-16 09:11:58

Stanford University New synthetic nanoparticle could disinfect, depollute, and desalinate contaminated water and then get removed magnetically. Among its many talents, silver is an antibiotic. Titanium dioxide is known to glom on to certain heavy metals and pollutants. Other materials do the same for salt. In recent years, environmental engineers have sought to disinfect, depollute, and desalinate contaminated water using nanoscale particles of these active materials. Engineers call...

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...
