State-of-the-art flame retardant cotton textiles suffer from release of formaldehyde and are uncomfortable to wear. Empa scientists managed to circumvent this problem by creating a physically and chemically independent network of flame retardants inside the fibers. This approach retains the inherent more
Chemical syntheses of new active ingredients or functional materials are based on the use of molecular building blocks. These must be simultaneously reactive but also stable enough to enable targeted incorporation into larger molecules. A research team from the University of Göttingen and the Goethe more
Blue phosphorus, an atomically thin synthetic semiconductor, becomes metallic as soon as it is converted into a double layer. This has been discovered by an interdisciplinary team led by Prof Thomas Heine from TU Dresden and Prof Gabriel Merino from the Mexican research institute Cinvestav Merida. T more
Matches, as it turns out, have been around for a long time. Sulfur-based matches are mentioned as far back as the 1200s in texts of the time, and in the 1600s a process involving drawing sulfur matches through dried phosphorus-soaked paper was devised. However, the friction matches we’re used to hav more
The latest of the element infographics looks at the Group 5 elements. There is, once again, an interesting fact that I couldn’t quite fit in, or left out at the expense of others: Bismuth-209 was long thought to have heaviest stable nucleus of any element, until 2003 when it was determined by French more
There are an isolated few graphics online that look at elements involved in the manufacture of a smartphone – for example, this ‘Periodic Table of iPhones’ – but there’s actually remarkably little easily accessible information out there that details the specific compounds used for specific purposes more
For the first time, black phosphorus quantum dots (BP QDs) were found to show chemiluminescence (CL) properties in the presence of hydrogen peroxide (H2O2) and hypochlorite (ClO−). Excited phosphorus oxides (HPO) resulting from the oxidation of BP QDs account for CL emission. Taking triacetone tripe more
Readily available P-tBu substituted Li/Cl phosphinidenoid complexes react with carbonyl compounds to furnish sterically almost unhindered oxaphosphirane complexes that reveal new and surprisingly facile intra- and intermolecular ring expansion reactions. 1,3,2-Dioxaphosphole complex formation is exp more

Phosphorus Phosphorus, (, meaning "light", and phoros meaning "bearer"), is the chemical element that has the symbol P and atomic number 15. A multivalent nonmetal of the nitrogen group , phosphorus is commonly found in inorganic phosphate ... more
