  2. Antiknock agent - Wikipedia

    en.wikipedia.org/wiki/Antiknock_agent

    Ferrocene and its numerous derivatives have no large-scale applications, but have many niche uses that exploit their unusual structure (ligand scaffolds, pharmaceutical candidates), robustness (anti-knock formulations, precursors to materials), and redox reactions (reagents and redox standards). Use for global cooling has been proposed. [17]

  3. Octane rating - Wikipedia

    en.wikipedia.org/wiki/Octane_rating

    In most countries in Europe, and in Australia and New Zealand, the "headline" octane rating prominently displayed on the pump is the RON, but in Canada, the United States, and Mexico, the headline number is the simple mean or average of the RON and the MON, called the Anti-Knock Index (AKI), and often written on pumps as (R+M)/2.

  4. Bristol Type 138 - Wikipedia

    Of note, this fuel has a high anti-knock value; the high degree of supercharge involved results in the fuel mixture reaching high temperatures, which generally increases the potential for detonation, thus a high anti-knock value was viewed to be of critical importance. [14]

  6. Pratt & Whitney R-2800 Double Wasp - Wikipedia

    en.wikipedia.org/wiki/Pratt_&_Whitney_R-2800...

    When the US entered the war in December 1941, designs advanced rapidly, and long-established engines such as the Wright Cyclone and Double Wasp were re-rated on fuel of much higher octane rating (anti-knock value) to give considerably more power. By 1944, versions of the R-2800 powering late-model P-47s (and other aircraft) had a rating ...

  7. Heptane - Wikipedia

    en.wikipedia.org/wiki/Heptane

    Heptane or n-heptane is the straight-chain alkane with the chemical formula H 3 C(CH 2) 5 CH 3 or C 7 H 16.When used as a test fuel component in anti-knock test engines, a 100% heptane fuel is the zero point of the octane rating scale (the 100 point is 100% iso-octane).

    An experimental nasal spray has helped clear toxic protein buildups in the brains of mouse models of Alzheimer's. Its developers believe the spray may help delay Alzheimer's by at least a decade.

    en.wikipedia.org/wiki/Methyl_tert-butyl_ether

    Methyl tert-butyl ether (MTBE), also known as tert-butyl methyl ether, is an organic compound with a structural formula (CH 3) 3 COCH 3.MTBE is a volatile, flammable, and colorless liquid that is sparingly soluble in water. [1]
