Teflonates — an anion class name derived from the trade name Teflon

The word teflonate is derived from the brand name Teflon, commonly used to denote the perfluorinated polymer poly(tetrafluoroethylene) (PTFE). Chemically, teflonates are not derived from Teflon. The word teflonate applies to any member of the following anion class: [Al(OR_F)₄]^–. The anions of this class are aluminates(-1) (also: alumanuides), consisting of a central aluminum atom that is tetrasubstituted by perfluoroalkoxy (OR_F) groups. The molecular surface (molecular envelope) of a teflonate anion is dominated by fluorine atoms adjacent to carbon atoms (C-F bonds), similar to the surface of a Teflon macromolecule. This explains, why some chemists like to assign a name similarity between Teflon and [Al(OR_F)₄]^– (tetra(perfluoroalkoxy)aluminates(-1) or tetra(perfluoroalkoxy)alumanuides).

Acronyms: CAO, CEO, CFO, CIO, COO and CTO

These acronyms stand for chief managing positions in a company. A person holding such a position can be considered as a Chief Managing Officer (CMO). Now you may guess the meaning of the acronyms by replacing the word Managing by a word describing an activity or department critical to the success of a company:

CAO: Chief Advertising Officer
CEO: Chief Executive Officer
CFO: Chief Financial Officer
CIO: Chief Information Officer
COO: Chief Operating Officer
CTO: Chief Technology Officer

Of course, it doesn't stop here. CSO, for example, can refer to a Chief Strategy Officer, Chief Security Officer, or Chief Sourcing Officer. And who hasn't heard of a Chief Disinformation Officer (CDO) or a Chief Vacationing Officer (CVO)?

Acronym: WESRF for Wallace Energy Systems & Renewables Facility

The WESRF research center has been named

in memory of [Alan] Wallace, who died in 2006, but the Wallace Energy Systems & Renewables Facility (WESRF) is familiarly known as “We Surf.”

Alan Wallace was a professor of electrical engineering at Oregon State University, where he along with Annette von Jouanne and others shared their fascination of ocean's power and studied wave-energy converters.
At WESRF, research and testing is focusing on (although not limited to) surfing objects including an all-electric naval ship, a hovercraft and buoys such as wave-energy converters designed by von Jouanne.

Italian: Capo pazzo • English: mad head • French: tête folle • German: verrückter Kopf

Mad heads are found in all professions. But it is difficult to believe that a composer of beautiful Baroque music, such as the Italian violinist-composer Francesco Maria Veracini (1690-1768) had his dark side:

During the following ten years [1723 and after], during which he was generally inFlorence, he earned a continuing reputation for mental instability, exemplified by an attempt to kill his wife and by eccentricities that brought him the descriptive title of Capo pazzo (mad head).

Spanish: Santiago de Compostela • French: Saint Jacques de Compostelle

Occasionally, you'll find street names explained right on spot next to the street sign, as found in Hanover. No need for a guide book or iPhone! Sometimes, however, nothing can replace a personal description that expresses familarity with a given place and provides the historical background. One such example is the rue Saint-Jacques in Paris, France. Reading Thad Carhart's lovely book about a piano shop in Paris [1], you are getting more than just a history tour of piano making:

One day [...] I walked home from a friend's apartment in the Latin Quarter by a roundabout way, purposely taking the narrow street that leads past my favorite church in Paris, Val de Grâce. It lies on the rue Saint-Jacques, a small but noisy thoroughfare that has led south since the time when Paris was the Roman city of Lutetia. Its current name derives from its use as a route in the Middle Ages for pilgrims heading to Santiago de Compostela in Spain; or, in the usage the French prefer, Saint Jacques de Compostelle. Val de Grâce is a large late Renaissance church that is unusual for Paris; its exuberant carvings and animated façade are more typical of Rome, and the most beautiful dome in the city graces its undulating mass of light yellow stone.

Acronyms: TMBX, TMEX and TMOX are TMAXs

[S-(2H-thiophen-2-yl)]-methyl-alkyl xanthates (TMAXs) are xanthate (dithiocarbonate) derivatives of thiophen. TMAXs have been investigated as additives to rapeseed oil, which is applied as steel-steel lubricant. Selected chemical members of the TMAX compound class are:

TMEX: [S-(2H-thiophen-2-yl)]-methyl-ethyl xanthate
TMBX: [S-(2H-thiophen-2-yl)]-methyl-butyl xanthate
TMOX: [S-(2H-thiophen-2-yl)]-methyl-octyl xanthate

From the name Jagannatha to the noun juggernaut

A juggernaut is something that crushes or seems to crush everything in its path. Literally, this something can be a heavy vehicle such as a steamroller. The word juggernaut can also refer to a strong force, either physically or spiritually, that exercises power. Julia Whitty, with roots in the Indian state of Bengal, explains the origin of the word juggernaut from the local name for the god Krishna: Jagannatha, the Lord of the Universe, whose home is the Temple of Jagannatha in Puri on the Bay of Bengal [1]. Each year Jagannatha is worshipped by being taken on a tour as an oversized head with arms coming out of his ears. Aboard a huge chariot, Jagannatha makes its way to the Gundicha temple through the sea of ecstatic worshippers:

Along the way, most years, a few unlucky disciples are crushed beneath the wheels of the chariot, while others throw themselves under (or once did), desiring deliverance from the cycle of birth and death and the subsequent bliss of nirvana. Upon witnessing Jagannatha's monstrous chariot, its unhurried and invariably deadly path, the British coined the word juggernaut.
