Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
- another term for alkene
- ‘The company said the quarter saw a decline in international prices of olefins, polymer as well as fibre-intermediate on the back of weaker crude oil prices compared with the trailing quarter.’
- ‘The device has three injection-molded elements made of a cyclic olefin copolymer: the lid, a mixing chamber and a delivery cartridge.’
- ‘The material is a thermoplastic olefin nanocomposite.’
- ‘Epoxidation, the conversion of an olefin (an unsaturated alkene hydrocarbon) to a cyclic ether through reaction with hydrogen peroxide, a peracid, or oxygen, is an important chemical technique.’
- ‘In addition, the isomerization of olefins with small molecular weight in glassy solvent at 77 K have been proposed to proceed by H-T mechanism.’
- ‘Classes of polymers used in integrated optics include acrylates, polyimides, polycarbonates, and olefins.’
- ‘Activator solid support for metallocene catalysts in the polymerization of olefins, a process for preparing such a support, and the corresponding catalytic system and polymerization process’
- ‘Thermoplastic olefin was considered instead of the vinyl substrate covering.’
- ‘By use of the present invention it is possible to produce an olefin polymer with high stereoregularity, broad molecular weight distribution, and good fluidity, at high rates of yield.’
- ‘Such investment will be made in the production of plastic pellets, olefins, and aromatics.’
- ‘Process for selective hydrogenation of highly unsaturated compounds and isomerization of olefins in hydrocarbon streams’
- ‘Sharpless had begun his investigations into the oxidation of olefins after starting work as an assistant professor at the Massachusetts Institute of Technology in 1970.’
- ‘It is preferred that the top membrane portion and the base membrane portion are made from thermoplastic olefin material or polyvinyl chloride material.’
- ‘Whatever the feedstock, the product slate is a complex mixture of hydrogen, ethylene, other olefins, diolefins and gasoline as well as smaller amounts of acetylenes and carbon monoxide.’
- ‘I've never done an olefin metathesis reaction, which means that the trend started without me and will leave without me.’
- ‘The second phase comprises an organic solvent containing soluble reagents such as olefins.’
- ‘For the pathway of cis-trans isomerization of olefins, we suggest distinguishing conjugated olefins (including stilbenes) of little polarity from other cases.’
- ‘There are four large plants here - Qenos resins, plastics, elastomers and olefins.’
- ‘Process for the preparation of an olefin polymer using metallocenes having specifically substituted indenyl ligands’
- ‘Ethylene, a two-carbon olefin, is a volatile hormone in higher plants.’
Mid 19th century: from French oléfiant oil-forming (with reference to oily ethylene dichloride).
