Hydrothermal vents and the origins of life - Chemistry World
网页2017年4月16日 · In 1977, the first deep sea hydrothermal vent was discovered in the East Pacific Rise mid-oceanic ridge. Named ‘black smokers’, the vents emit geothermally heated water up to 400°C, with high levels of sulfides that precipitate on contact with the cold ocean to form the black smoke. This was followed in 2000 by the discovery of a new type ...
What is an element? | Feature | Chemistry World
网页2019年1月10日 · Iupac currently gives a double definition of ‘element’ in its ‘Gold Book’ of chemical terminology, which says that the word can refer either to a ‘species of atom’ (which Ghibaudi sees as akin to Paneth’s ‘basic substance’) or, rather tautologically, to a ‘pure elementary substance’. This double meaning is uncomfortable.
The rise of ferrofluids | Feature | Chemistry World
网页2021年6月14日 · Magnetic medicine. A true ferrofluid is a magnetic colloid; a stable suspension of magnetic particles in an oil- or water-based carrier liquid made by milling iron oxide in a surfactant, or by chemical synthesis. The magnetic particles are small enough, usually between 3–15nm, to move by Brownian motion outside of a magnetic field and do …
The father of the periodic table | Feature | Chemistry World
网页2019年1月2日 · 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 ...
Explainer: The chemistry of farts | News | Chemistry World
网页2016年12月21日 · 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 high …
Explainer: The science of alkyl nitrites aka poppers
网页2021年9月16日 · 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 ...
New rationale for 15-element wide f block - Chemistry World
网页2018年5月21日 · Unlike plutonium or uranium, these shielded f orbitals did not participate in bonding with the cage atoms. The empty f orbitals of actinium and lanthanum behaved in a similar way, causing Ghanty to recommend that all four elements belong in a 15-element wide f block as followed by IUPAC. Physical chemist Laurence Lavelle, from the …
Not just batteries: The chemistry of electric cars
网页2022年4月24日 · 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, …
