Iron oxides occur in nature in many forms, often significantly different from each other in terms of structure and physical properties. However, a new variety of iron oxide, recently created and tested by scientists in Cracow, surprised both physicists and engineers, as it revealed features previously unobserved in any other material. read more
Rumors of a truly unbreakable glass breakthrough are greatly exaggerated. In late October, scientists in Japan revealed that they had successfully developed a new form of oxide glass that is as strong as cast iron and, by one metric,...Show More Summary
A video from The Royal Institution explains in a very calm, subdued, British way what happens when you burn iron oxide and aluminum powder inside a pumpkin. The visual effects are quite impressive. (YouTube link) It’s also quite dangerous, so don’t try this at home. Please. Thermite is nothing to fool around with. -via The Daily Dot
Two jack-o’-lanterns demonstrate an explosive thermite reaction in a fiery halloween science video by the Royal Institution of Great Britain. Host Andy Marmery explains the powerful exothermic reaction between iron oxide and aluminum powders that erupts and sets off a wad of gun cotton in the second pumpkin.
What You'll Be Creating Rust. That beautifully terrible oxidation of iron elements. It's a fact of life in our world filled with metal and machines. Time and moisture take their toll, and even our most magnificent machines deteriorate. Show More Summary
Using pictures with atomic resolution, the mechanism of an important chemical reaction has finally be explained: When platinum nanoparticles act as catalysts on an iron oxide surface, the surface plays a crucial role.
An isolated, iron-rich bay in the heart of East Africa is offering scientists a rare glimpse back into Earth's primitive marine environment, and supports theories that tiny microbes created some of the world's largest ore deposits billions...Show More Summary
Itch-relieving action for the summer starts with this eponymous pink stuff, a cocktail of zinc oxide and a little iron oxide. The post What’s Inside Caladryl Will Not Make You Hallucinate appeared first on WIRED.
A stunning timelapse video of Vermilion Cliffs National Monument in Arizona. Vermilion Cliffs hosts some of the most unique landscapes on the planet, from the red iron oxide cliffs of its namesake, to the Jurassic-era petrified sandstone of White Pocket. Vimeo link (thanks Cora) The Presurfer
Biogenic Iron-Rich Filaments in the Quartz Veins in the Uppermost Ediacaran Qigebulake Formation, Aksu Area, Northwestern Tarim Basin, China: Implications for Iron Oxidizers in Subseafloor Hydrothermal Systems Authors:Zhou et alAbstract:Fe-(oxyhydr)oxide-encrusted...Show More Summary
Those bacteria that require iron walk a tightrope. Iron is essential for their growth, but too much iron can damage DNA and enzymes through oxidation. Therefore, bacteria have machinery to maintain their intracellular iron within a range that is healthy for them, scientists report.
You're up in the mountains, the snow is blindingly white, and the sun is blazing down from the sky: ideal skiing conditions -- but any skiers carrying the herpes virus might also have to reckon with the onset of cold sores after their day out. Show More Summary
Toxic sludge paint, made from the iron oxide pigments found in polluted streams, could fund its own large scale clean-up operation.
Precipitation of iron silicate nanoparticles in early Precambrian oceans marks Earth's first iron ageAuthors:Rasmussen et alAbstract:The early ocean was characterized by anoxic, iron-rich (ferruginous) conditions before the rise of atmospheric oxygen ?2.45 b.y. Show More Summary
If you didn't think anything beautiful could come from toxic waste, well, think again. Ohio University art professor John Sabraw and civil engineer Guy Riefler have joined forces and devised a method for extracting iron oxide metals from industrial waste. The extracts can then be turned into vibrant pigments and used to create stunning works of art. Read more...
I added the feet today to the pot I made yesterday (see previous post).The shape I am basing it is on this teapot on the far left. That is a stoneware that was gas fired to cone 10 and covered with an all over iron oxide decal pattern...Show More Summary
Lavender Hand-painted Ceramic Bead I thought I would showcase this bead that I currently have available at my Etsy store. I drew that daisy, scanned the drawing, saved it as a 300dpi jpg photo, and opened up my word processing program. Show More Summary
The Fountain Paint Pots in Yellowstone National Park are named for the colorful muds produced by the oxidizing iron in the mud, the natural result of hot springs. In November 2014, a light dusting of snow both revealed the topography of the area and made the steam rising from the ground clear and eerie. Read more...
Iron oxides, divalent cations, silica, and the early earth phosphorus crisisAuthors:Jones et alAbstract:As a nutrient required for growth, phosphorus regulates the activity of life in the oceans. Iron oxides sorb phosphorus from seawater,...Show More Summary
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.
