chlorofluorocarbons (plural)
CFC (abbreviation)
CFK (abbreviation rare)

The proposed replacement for CFC-11, a chlorofluorocarbon used to make plastic foam and in central air-conditioning systems, is a compound called HCFC-22. This is a chlorofluorocarbon already in use in home air-conditioners, but it is more expensive than CFC-11 and its potential applications are limited by its inferior characteristics.

1989 March 7, Malcolm W. Browne, “In Protecting the Atmosphere, Choices Are Costly and Complex”, in The New York Times:

The Renew is also free of polyvinyl chloride, asbestos, chlorofluorocarbons and halons.

2009 February 12, Azadeh Ensha, “A Cellphone That Is Made With the Environment in Mind”, in The New York Times:

(organic chemistry) Any of a class of organic compounds in which the hydrogen atoms of a hydrocarbon are replaced with those of chlorine and fluorine; formerly used as refrigerants and aerosol can propellants but withdrawn due to causing damage to the ozone layer.

fossil fuel

Coordinate term: renewable

Without renewables, we’ll still end up burning (albeit much more efficiently) the same coal and natural gas that we burn today in our power plants and the same fuel oil that we burn in our cars and trucks. And it is precisely these carbon-based fossil fuels that we must distance ourselves from if we really want to come to grips with our dependence on foreign oil and with global warming.

2006 October 11, Robert B. Semple Jr., “Beyond Fossil Fuels”, in New York Times:

The basic point is that we are entering uncharted territory. This toothless statement has been true at every point in history. But I believe that this century is the one in which we must confront the thorniest issue ever presented to the human race. This moment is special because we have dramatically built up our population, technology, science, medicine, and democratic institutions as a direct result of vast amounts of surplus energy stemming from a one-time resource. The fossil fuel experience has made us dangerously confident about our cleverness and dominance over nature. What makes this century special, then, is that we will have to cope with a diminishing supply rate of the resource that has been of paramount importance to our high-tech existence.

2011 October 5, Tom Murphy, “"Sustainable" Means Bunkty to Me”, in Do the Math:

Any fuel derived from hydrocarbon deposits such as coal, petroleum, natural gas and, to some extent, peat; these fuels are non-renewable, and their burning moves carbon from underground into the atmosphere via the greenhouse gas carbon dioxide.

biofuel

pig iron

en-noun

pig iron (usually uncountable, plural pig irons)

We spent a lot of time up on the staging of the great furnaces, trying to pick up the tricks of the trade from the taciturn furnacemen who sat around placidly smoking, or chewing twist, and occasionally throwing in more pig iron to the molten white-hot metal.

1945 January and February, A Former Pupil, “Some Memories of Crewe Works—III”, in Railway Magazine, page 14:

A type of crude, brittle iron shaped like a block, unsuitable for working but suitable for casting, commonly used as an industrial raw material.


flare

→ Italian: flare

Origin unknown, first recorded in the mid 16th century, probably related to Latin flagrō (“I burn”). Norwegian flara (“to blaze; to flaunt in gaudy attire”) has a similar meaning, but the English word predates it. Possibly related to Middle High German vlederen (“to flutter”), represented by modern German flattern.
The noun is derived from the verb.

unknown

Origin unknown

Stulp

widening of an object with otherwise roughly constant width

разкрояване

widening of the lower legs of trousers and jeans

Flare stacks are used in gas plants, petroleum refineries, and petrochemical plants to combust surplus hydrocarbons to produce combustion products that are neither toxic nor combustible. Flares frequently incorporate a liquid-gas separator at the base of the stack and steam assisted burner nozzles at the top of the stack to aid complete combustion.

2013, David Brennan, “Identification of Waste in Utility Systems”, in Sustainable Process Engineering: Concepts, Strategies, Evaluation, and Implementation, Singapore: Pan Stanford Publishing, →ISBN, part B (Strategies), section 6.8 (Flare Stacks), page 122:

A source of brightly burning light or intense heat.

The English word is cognate with Italian saturnino (“saturnine”), Portuguese saturnino (“melancholy, saturnine; pertaining to the planet Saturn”), Spanish saturnino (“melancholy, saturnine; pertaining to the planet Saturn”).
Sense 1 (“having a tendency to be cold, bitter, gloomy, etc.”) refers to the fact that individuals born under the astrological influence of the planet Saturn were believed to have that disposition.

cog

The slow saturation of the animal economy by the metal renders the individual saturnine, and prepares in him a fresh ground, containing a reserve of lead, which, under the influence of accidental causes, may pass back in a notable quantity into the blood and bring on accidents analogous to those of acute poisoning or presenting special characteristics. The first effects of lead impregnation are, production of saturnine anæmia [...] acute or chronic saturnine asthma then come on; [...]

lignite

en-noun

lignite (countable and uncountable, plural lignites)

From French lignite, from Latin lignum (“firewood”) + -ite.

Texas industry is turning to lignite, a kind of poor man's coal, to replace its dwindling allocations of natural gas. The Lone Star State now gets an estimated 12 percent of its electricity from lignite, and that figure is expected to double by 1985.

1978 February 14, “Texas Turning to Its Reserves of Lignite”, in New York Times:

[Robert] Habeck, who has found himself in the extremely uncomfortable position of turning from a long-term campaigner against fossil fuels to a short-term defender of them, said: “Putin’s war of aggression is forcing us to temporarily make greater use of lignite so that we save gas in electricity generation. This is painful but necessary in view of the shortage of gas.”

2023 January 10, Kate Connolly, “Climate activists ‘prepared to risk lives’ to stop German coalmine”, in The Guardian:


selenite

selenite (countable and uncountable, plural selenites)

corium

(anatomy) The deep layer of mucous membranes beneath the epithelium.

Passing by the Corium Bubulum of the Classical Ancients, we see in an old charter, dated 1036, "Stallus Sutoris Vaccæ," i. e. the stall of a shoe-maker who used cow-skin.

1825, Thomas Dudley Fosbroke, Encyclopaedia of antiquities, and elements of archaeology, classical and mediæval:

(historical) Armour made of leather, particularly that used by the Romans.


corium

From core + -ium. Apparently coined in 1974 by Martin Peehs, a German nuclear engineer.

1974, Martin Peehs, “Investigations of molten "corium" phases”, in Thermodynamics of Nuclear Materials, volume 1, Vienna: International Atomic Agency IAEA-SM-190/10:

Mexico was given $100,000 to do a series of experiments in which small amounts (10 to 20 grams) of stainless steel and corium (a mixture of 55 percent iron, 10 percent zirconium, and 35 percent uranium dioxide) will be melted and then flooded with water in an arc-melting chamber.

1975 21 October, Hearings on the Nuclear Initiative: Technological Concerns in Nuclear Reactor Safety, Sacramento (CA): California Legislature Assembly Committee on Resources, Land Use, and Energy:

Previous studies of the thermal behavior of corium in a degraded nuclear reactor have focussed primarily on the process of heat transfer within the corium.

1991, Sheau-Wen Shiah, Fan-bill B. Cheung, Dae-Ho Cho, Michael J. Tan, Louis Baker Jr., “Numerical Modeling of Corium/Steel Structure Interaction with Downfacing Boiling Boundary Conditions”, in Chung, Franklin, Hochreiter, Larry E., editors, Numerical Modelling of Basic Heat Transfer Phenomena in Nuclear Systems, presented at the 28th National Heat Transfer Conference, Minneapolis, Minnesota, July 28-31, 1991, New York (NY): American Society of Mechanical Engineers, page 31:

2009, Wei Wei, Xing-rong Cao, “The Simulation of Corium Dispersion in Direct Containment Heating Accidents”, in Zero Carbon Energy Kyoto 2009:

The materials of the nuclear reactor—nuclear oxide fuel and fission products, cladding, metallic alloys, moderator, absorbers, structural materials, coolants, concrete, and so on, could melt to form complex, multiphases, and aggressive mixtures known by the general term corium.

2011, Pascal Piluso, “Appendix 1: Corium Thermodynamics and Thermophysics, 2. Corium Thermophysics”, in Bal Raj Seghal, editor, Nuclear Safety in Light Water Reactors: Severe Accident Phenomenology, Waltham (MA): Academic Press, →ISBN, page 664:
