In the future fusion reactor, plasma is confined by using the magnetic field inside the doughnut-shaped vacuum vessel. The blanket is in a location where it almost touches the plasma, and as if to enfold the plasma the blanket is placed on the inner surface of the vacuum chamber. The blanket, by abs more
Compounds with the apatite structure differ from most classes by the variety of their chemical compositions: to create such substances, most chemical elements of the Periodic System can be used, while the characteristics of the crystalline structure of apatite will be preserved. The resulting variet more
Corrosion is an age-old problem that is estimated to cost about $1 trillion a year, or about 5 percent of the U.S. gross domestic product. Corrosion of metals can be particularly bad, but fortunately they are normally protected from catastrophic damage by naturally forming, super-thin oxide films. T more
You may deem the chance slim that mythical monsters are hiding underneath your offspring’s beds. However, danger might be lurking there in the form of toy blocks, action figures, or crayons. Hazardous substances found in everyday items, including toy more
This graphic looks at the colours of transition metal ions when they are in aqueous solution (in water), and also looks at the reason why we see coloured compounds and complexes for transition metals. This helps explain, for example, why rust (iron oxide) is an orange colour, and why the Statue of L more
A previous post looked at the colours of transition metals, and the origin of their colours – this graphic, on the other hand, looks at how transition metals (and some non-transition metals) can be identified by the precipitates they form with sodium hydroxide and ammonia solutions. I’m going to kee more
Many of us enjoyed watching spectacular fireworks displays to usher in the new year. However, the vibrant colours of fireworks belie the effects that they can have on the environment. With this graphic, we take a look at some of the issues that they can cause. more
The mobility and toxicity of chromium (Cr) in soil and water systems are largely controlled by its oxidation state and interactions with solid phases. Relative to abiotic minerals, biogenic iron (Fe) (oxyhydr)oxides (BIOS) may enhance Cr(VI) adsorption and reduction due to their poorly ordered struc more
Magnetic multilayer devices that exploit magnetoresistance are the backbone of magnetic sensing and data storage technologies. Here, we report multiple-spin-filter magnetic tunnel junctions (sf-MTJs) based on van der Waals (vdW) heterostructures in which atomically thin chromium triiodide (CrI3) ac more
