Ethylene is a hormone that affects the ripening and flowering of many plants. It is widely used to control freshness in horticulture and fruits. [20] The scrubbing of naturally occurring ethylene delays ripening. [21] Adsorption of ethylene by nets coated in titanium dioxide gel has also been shown to be effective. [22]
The methanol economy is a suggested future economy in which methanol and dimethyl ether replace fossil fuels as a means of energy storage, ground transportation fuel, and raw material for synthetic hydrocarbons and their products.
Hydrogen, being the lightest existing gas (7% the density of air, 0.08988 g/L at STP), seems to be the most appropriate gas for lifting.It can be easily produced in large quantities, for example with the water-gas shift reaction or electrolysis, but hydrogen has several disadvantages:
Abney’s viral video takes place in his car, so it’s only fitting that he took aim at two extortionate driving expenses: insurance and gas. “My car insurance from four-years-ago until now ...

Miracle Planet is a six-part documentary series, co-produced by Japan's NHK and the National Film Board of Canada (NFB), narrated by Christopher Plummer (Seiko Nakajo in the original Japanese), which tells the 4.6-billion-year-old story of how life has evolved from its humble beginnings to the diversity of living creatures today.
Ethylene tetrafluoroethylene (ETFE) is a fluorine-based plastic. It was designed to have high corrosion resistance and strength over a wide temperature range. ETFE is a polymer and its source-based name is poly (ethene-co-tetrafluoroethene). It is also known under the DuPont brand name Tefzel and is sometimes referred to as 'Teflon Film'. ETFE ...
At the chemical level, ethylene mediates the reduction in the amount of fragrance volatiles produced. Fragrance volatiles act mostly by attracting pollinators. Ethylene's role in this developmental scenario is to move the plant away from a state of attracting pollinators, so it also aids in decreasing the production of these volatiles.
