Explainer: The science of alkyl nitrites aka poppers
WEBSep 16, 2021 · Inhaling alkyl nitrites feels like becoming instantly drunk according to some users, although the effect lasts for only a few minutes. Also known as poppers, these chemicals have been taken recreationally since the 1960s. Although they are sold openly, usually in small brown bottles with enticing brand names such as ‘liquid gold’, their ...
The father of the periodic table | Feature | Chemistry World
WEBJan 2, 2019 · A century and a half ago, Dmitri Mendeleev took a crucial step in this search for order among the elements, by publishing the first draft of his periodic table. In 2019 the world-wide community of chemists is celebrating this anniversary, and rightly so. Like Stonehenge, the table reflects regularities in nature which were due to causes that ...

WEBDec 21, 2016 · The men farted between two and 53 times a day, with an average of 12.7, while women farted between once and 32 times a day, with an average of 7.1 times. The number of farts was higher when people ate more fibre. The study shows farting is normal, Stanton says. ‘I hope that has translated to people being prepared to eat more foods …
Not just batteries: The chemistry of electric cars
WEBApr 24, 2022 · The internal combustion engine is not dead, but it may be beginning to die. One of the few bold steps taken at the November 2021 Cop26 climate conference in Glasgow, UK, was a declaration on phasing out sales of petrol and diesel cars by 2040 in all markets and by 2035 in leading ones: many European countries have set earlier dates, …
How elements are made beyond the stars - Chemistry World
WEBJan 5, 2022 · Elements are made in space by a variety of processes, but scientists are still getting to grips with the exact details. After bismuth-209, however, the s-process hits a wall. Adding an extra neutron gives bismuth-210, which decays to polonium-210. This undergoes alpha decay to lead-206. Further neutron capture simply repeats the cycle.
Simulations solve mystery of why silver tarnishes | Research ...
WEBMar 28, 2019 · The long standing mystery of why silver tarnishes much more quickly when exposed to sulfur, rather than oxygen, has been solved using molecular dynamics simulations. The work could be useful for producing corrosion-resistant silver to prevent circuit board failure, as well as help conservators of silver jewellery and historical artefacts.

Explainer: The chemistry that keeps swimming pools clean and safe
WEBAug 4, 2022 · Chloramines can form in various ways in swimming pools. One of the simplest is the reaction of ammonia-like compounds, such as urea from swimmers, with hypochlorous acid. This leads to the formation of mono-, di- and trichloramines. Chloramine formation: R 2 NH + HOCl → R 2 NCl + H 2 O. These toxic chloramines then evaporate, …
