A new look at the finer details of rust show an assumed atomic structure has been wrong all along

Scientists have been studying the behavior of iron oxide surfaces. The atomic structure of iron oxide, which had been assumed to be well-established, turned out to be wrong. The behavior of iron oxide is governed by missing iron atoms in the atomic layer directly below the surface. This is a big surprise with potential applications in chemical catalysis, electronics or medicine.

New materials for more powerful solar cells

Applying a thin film of metallic oxide significantly boosts the performance of solar panel cells. Researchers have developed a new class of materials comprising elements such as bismuth, iron, chromium, and oxygen. These 'multiferroic' materials absorb solar radiation and possess unique electrical and magnetic properties.

Fossil Evidence of Iron Oxidizing Bacteria From the Great Oxidation Event

Nanomedicine Company MagForce Takes $15M From Thiel’s Mithril Capital

6 months agoTechnology : TechCrunch

MagForce injects iron oxide nanoparticles into a patient and then vibrates them with a magnetic field to generate heat that kills cancer cells. It sounds like science fiction but it’s real. That’s why Peter Thiel’s late-stage investment firm Mithril just led a $15 million investment into MagForce’s new American subsidary that values it at $65 million. Founded in 1997… Read More

Nanoscale composites improve MRI: Magnetic particles merged to detect, fight disease

Submicrometer particles that contain even smaller particles of iron oxide could make magnetic resonance imaging a far more powerful tool to detect and fight disease. Medical researchers are creating composite particles that can be injected into patients and guided by magnetic fields. Show More Summary

HOUSTON – (June 16, 2014) – Submicroscopic particles that contain even smaller particles of iron oxide could make magnetic resonance imaging (MRI) a far more powerful tool to detect and fight disease. Scientists at Rice University and...Show More Summary

Promising results with local hyperthermia of tumors

Combined use of iron oxide nanoparticles and an alternating magnetic field can induce local hyperthermia in tumors in a controlled and uniform manner. The results Induced anti-tumor immune response that reduced the risk of recurrence and metastasis. Show More Summary

Research and applications of iron oxide nanoparticles explored

A scientist spent thirty years investigating how craftsman were able to render the beautiful red colors in Bizen and Arita pottery. This research revealed the important role of iron oxide particles for producing the colors. Now he is...Show More Summary

Tiny Timber Noa is a Playful, Six-Sided Prefab Modular Cabin in Estonia

The 270 square foot Noa house features a hexagonal floor plan and is built entirely from wood, with the exterior boards treated with iron oxide for a silvery aged finish. Since each side of the house, from the walls to the roof panels, are identically sized

Handpainted with Iron Oxice Designs

12 months agoArts / Ceramics : NKP Designs

After I scrolled thick black lines on this bead, I applied my hand-drawn lacy iron oxide decal and re-fired. I found it in a bowlful of beads which was sitting in my living room and thought I'd offer it for sale. Find it here.

Iron Oxide Orchid Nugget Beads

I was surprised to find these had 26 views since uploading them late last week. They were originally this lovely purple shade and I added some original homemade iron oxide decals of my own drawings and refired them. The decals came out perfectly and I am very happy with them. Show More Summary

Reclaimed Iron Oxide: Ceramic Artists Use the Byproduct of an Environmental Clean Up

I grew up in Western Pennsylvania (coal country), and I can remember an orange-tinged stream close to my grandmother's house. The cause was Acid Mine Drainage, which contaminates waterways near coal mines with iron, creating biological dead zones. Show More Summary

Welcome 2014

Howdy and hello! I just added this sweet bead to my etsy store. It's a glaze I have played with in the past and I think it is visually more interesting with the addition of iron oxide decals, of my own creation of course.2014 is exciting. Show More Summary

Sticky business: Magnetic pollen replicas offer multimodal adhesion

Researchers have created magnetic replicas of sunflower pollen grains using a wet chemical, layer-by-layer process that applies highly conformal iron oxide coatings. The replicas possess natural adhesion properties from the pollen while gaining magnetic behavior.

Characterization of phenolic exudates from Phaeodactylum tricornutum and their effects on the chemistry of Fe(II)-Fe(III)

The effect of exudates from Phaeodactylum tricornutum on the iron chemistry has been studied at pH 8.0 and 7.5 in seawater and seawater enrichment with the diatom exudates. At pH 8.0 the rate constant for the oxidation of Fe(II) decreased by 29% in the presence of the exudates, while at pH 7.5, the rate constant decreased by 56%. […]
