Astonomers may have discovered the universe’s most ironic exoplanet

3 weeks agoTechnology / Gadgets : Gizmag

A team of astronomers may have discovered a "hot Jupiter" exoplanet with an atmosphere that snows titanium oxide – a kind of sunscreen – exclusively on the one side of the planet that is bathed in perpetual darkness. The study, which...Show More Summary

Iron Oxide and Iron Deposits

Banded Iron Formation Whilst in Frankfurt a few days ago, a team member from Everything Dinosaur took the opportunity to photograph some of the amazing outdoor exhibits on display opposite the Senckenberg Naturmuseum (Frankfurt Natural History Museum).  Amongst the stunning replicas of prehistoric plants and of course, the iconic, life-size model of Tyrannosaurus rex, our

This is how to make your own version of ferrofluid at home for a fraction of the price

This is how to make your own "ferripaste" at home. All it takes is black iron oxide to motor oil mixed in a 1 to 1 ratio. Iron oxide has some of the most magnetic properties that can be found in nature and when mixed with the motor oil,...Show More Summary

Reliable recipe for DIY ferrofluid

3 months agoHumor / odd : Boing Boing

Braniac75, after trying and failing to replicate the various online recipes for DIY ferrofluid (the consumer stuff is $200+ a liter), figured it out: 1 part iron oxide powder, 1 part "clinging" synthetic motor oil, a stirring stick,Show More Summary

New MRI contrast agent tested on big animals

(Institute for Basic Science) Experiments in dogs, rabbits and monkeys show the efficacy and biocompatibility of a new MRI/MRA contrast agent in detecting stroke. This T1 MRI contrast agent based on ultrasmall iron oxide nanoparticles could become a possible alternative to clinically used gadolinium-based agents.

This week from AGU: Greenland's summer ocean bloom likely fueled by iron

(American Geophysical Union) This week from AGU: Greenland's summer ocean bloom likely fueled by iron, new technique could help scientists track nitrous oxide sources, and more.

Rubbed Off

Early magnetic storage was simple in its construction. The earliest floppy disks and hard drives used an iron (III) oxide surface coating a plastic film or disk. Later media would use cobalt-based surfaces, providing a smaller data resolution than iron oxide, but wouldn’t change much. Samuel H. Show More Summary

Excavator Bucket

One of the pages in my watercolor sketchbook has a random orange underpainting in casein.It matches the orange color of the rust on this excavator bucket. I love the fact that the iron oxide of that rust is the same mineral in my raw sienna color that I use as I paint it. Show More Summary

Recall Watch: At Mazda, It Seems Rust Never Sleeps

Previous generations of the Mazda 3, while popular, soon became known as much for corrosion as for zoom-zoom potential. Tears of iron oxide poured from rear wheel arches, taillights and center-mounted brake lamps, adding a somewhat tragic element to the models’ insanely happy visage. Show More Summary

Manipulating Earth-abundant materials to harness the sun's energy

Depositing one layer of atoms at a time can result in materials that greatly improve fuel cells, batteries and other devices. In this research, scientists precisely added chromium to iron oxides to control the electronic and optical properties. Show More Summary

Magnets and Nanoparticles for On-Demand Leaky Vessels

5 months agoIndustries / Medical : medGadget

Scientists at Rice University have developed a method to open gaps between the endothelial cells that line blood vessels using a magnetic field and iron oxide nanoparticles. The gaps close by themselves after the researchers remove the magnets. They hope that the concept could be used to help deliver larger therapeutic molecules like proteins to […]

Evidence for hydrothermal alteration and source regions for the Kiruna iron oxide-apatite ore (northern Sweden) from zircon Hf and O isotopes

Zircon grains from the Kiruna iron oxide–apatite (IOA) ore bodies in northern Sweden are distinct in their hafnium and oxygen isotopic ratios compared to zircon grains from adjacent metavolcanic host rocks and related intrusions. Here,...Show More Summary

Watching rust transform into iron

Using a state-of-the-art microscopy technique, experimenters at the National Institute of Standards and Technology (NIST) and their colleagues have witnessed a slow-motion, atomic-scale transformation of rust—iron oxide—back to pure iron metal, in all of its chemical steps.

New iron oxide nanoparticles could help avoid a rare side effect caused by current contrast agents for MRI

A new, specially coated iron oxide nanoparticle developed by a team at MIT and elsewhere could provide an alternative to conventional gadolinium-based contrast agents used for magnetic resonance imaging (MRI) procedures. In rare cases, the currently used gadolinium agents have been found to produce adverse effects in patients with impaired kidney function.

A new contrast agent for MRI

(Massachusetts Institute of Technology) A specially coated iron oxide nanoparticle could provide an alternative to conventional gadolinium-based contrast agents used for magnetic resonance imaging (MRI). In rare cases, the currently used gadolinium agents have been found to produce adverse effects in patients with impaired kidney function.

Three new uranium-rich minerals unearthed in Utah

9 months agoTechnology / Gadgets : Gizmag

When oxygen interacts with some metals, it causes an oxidation reaction that results in what is known as a secondary mineral: iron oxide, or rust. Similarly, when oxygen interacts with uranium, an oxidation reaction occurs that, when mixed with other elements, can also create secondary minerals. Show More Summary

Iron(IV) hexahydrazide clathrochelate complexes synthesized in water by air oxidation

A really obscure forgotten audio format: “Talking rubber”

Iron oxide was mixed with rubber and molded into a 1/8" band that could be reused.

Tumor Associated Macrophages are Polarized to an Anti-Cancer Phenotype by Ferumoxytol

Ferumoxytol is an FDA-approved therapeutic for the treatment of anemia. It’s a solution of iron oxide nanoparticles roughly 17-31 nm in diameter and replenishes the body’s iron levels. Researchers from Stanford University have discovered...Show More Summary

Scientists uncover secret to gold's catalytic powers

Settling a decades-long debate, new research conclusively shows that a hierarchy of active species exists in gold on iron oxide catalysis designed for low temperature carbon monoxide oxidation; Nanoparticles, sub-nanometer clusters and dispersed atoms—as well as how the material is prepared—are all important for determining catalytic activity.
