FILTER RESULTS ►Deep Sea Lava Eruptions and the Carbon Cycle
Scientists from the Smithsonian and the University of Rhode Island have found unsuspected linkages between the oxidation state of iron in volcanic rocks and variations in the chemistry of the deep Earth. Not only do the trends run counter to predictions from recent decades of study, they belie a role for carbon circulating in the deep Earth. Show More Summary
Lava erupting on sea floor linked to deep-carbon cycle

Efficient Solar Water-Splitting Catalyst Developed
Ultra-thin films of nickel and iron oxides appear to be very effective catalysts for the solar-powered splitting of water into hydrogen and oxygen, new research from the University of Oregon has found. Such devices could be used to produce...Show More Summary
Thin films of nickel and iron oxides yield efficient solar water-splitting catalyst
EUGENE, Ore. -- (March 20, 2013) -- University of Oregon chemists say that ultra-thin films of nickel and iron oxides made through a solution synthesis process are promising catalysts to combine with semiconductors to make devices that capture sunlight and convert water into hydrogen and oxygen gases. read more
Study Reports Iron Oxide Nanoparticles Effective For Labeling Human Endothelial Cells
A team of researchers from three medical institutions in Guangzhou, China, have found that iron oxide nanoparticles (INOPS) are a useful contrast agent for in vivo magnetic resonance tracking of transplanted human endothelial cells. However, the impact of INOPS on the cells varies with a number of factors including the INOPS load. Show More Summary
"Morpho Towers — Two Standing Spirals."
"[I]t's ferrofluid, which is oil laced with bits of iron oxide. When the magnets are turned on, the little bits of iron (and the oil with them) are pulled by a magnetic field into columns and shapes that produce the 'tree.'"
Concrete House Showcasing a Volumetric Structure in Sao Paolo, Brazil
The Boaçava House in Sao Paolo, Brazil is a residential project with a strong and rigid structure, supported by asymmetrical concrete volumes and with the lower side “painted” in “red”, as a result of the iron oxide pigmentation. The...Show More Summary
Super-Earths May Generate Magnetic Fields Differently Than The Modern Earth
On the modern day Earth the magnetic field is thought to generated by electric currents in the liquid outer core, which is composed of highly conductive molten iron. But new research has found that when magnesium oxide is under extreme pressure and temperature it can behave similarly to molten iron, and could also generate a magnetic field. Show More Summary
Solar Energy Conversion And Storage Breakthrough, New Way To Split Water Molecules Into Hydrogen And Oxygen Created
A new way to split water molecules into hydrogen and oxygen by using just the sun and ultrathin films of iron oxide (rust) has been developed by researchers from the Technion-Israel Institute of Technology. This technological breakthrough will almost undoubtedly lead to more efficient, and less expensive, ways to store solar energy. By using [...]
Rust and sunshine could replace fossil fuels
Using sunlight and ultrathin films of iron oxide, or rust, Technion-Israel Institute of Technology researchers have found a new way to split water molecules into hydrogen and oxygen. read more
New way to split water molecules into hydrogen and oxygen: Breakthrough for solar energy conversion and storage?
Using the power of the sun and ultrathin films of iron oxide, Israeli researchers have found a novel way to split water molecules into hydrogen and oxygen. The breakthrough could lead to less expensive, more efficient ways to store solar energy in the form of hydrogen-based fuels.
The hunt for electron holes
Hematite, the mineral form of iron oxide (or trivially, rust), is a promising anode material for photoelectro-chemical cells (PEC) because of its affordability, availability, high stability and good spectral match to the solar spectrum. Show More Summary
The hunt for electron holes: A molecular glance on solar water splitting
Hydrogen production by solar water splitting in photoelectrochemical cells (PEC) has long been considered the holy grail of sustainable energy research. Iron oxide is a promising electrode material. Scientists have now gained in-depth insights into the electronic structure of an iron oxide electrode – while it was in operation. Show More Summary
Scientific American goes inside the rogue geo-engineering story
Recently, news broke that a scientist in Alaska had unilaterally launched a geo-engineering experiment — dumping iron sulfate and iron oxide into the Pacific Ocean. There were two goals to the project: First, grow a massive plankton bloom which would store atmospheric carbon the same way that trees take in and store atmospheric carbon; second, [...]
Nanoparticles and Magnets Join Forces to Kill Cancer Cells
Korean scientists at Yonsei University in Seoul have developed a new method of using a combination of zinc-doped iron oxide magnetic nanoparticles and an applied magnetic field to selectively kill cancer cells. They were able to show the effectiveness of the system in both laboratory colon cancer tissue as well as in tumors within living zebrafish. Show More Summary
MRI images transplanted islet cells with help of positively charged nanoparticles
Tampa, Fla. (Oct. 1, 2012) – In a study to investigate the detection by MRI of six kinds of positively-charged magnetic iron oxide nanoparticles designed to help monitor transplanted islet cells, a team of Japanese researchers foundShow More Summary
Low-Cost Battery Developments Could Provide Cheap Power Storage
A researcher at USC has developed a new method for inexpensive batteries that could be used for renewable power storage. These batteries use the oxidization of iron exposed to air (also known as rust) to store energy. As professor Sri...Show More Summary
Clearer look at how iron reacts in the environment
ARGONNE, ILL. (Sept. 6, 2012) -- Using ultrafast X-rays, scientists for the first time have watched how quickly electrons hop their way through rust nanoparticles. This gives key insight to how iron oxide, one of the most abundant minerals in soil, behaves and alters the condition of soil and water around it. Show More Summary
