The same is true for certain derivatives: N-formylpiperidine is a polar aprotic solvent with better hydrocarbon solubility than other amide solvents, and 2,2,6,6-tetramethylpiperidine is a highly sterically hindered base, useful because of its low nucleophilicity and high solubility in organic ...

Because the Space Force is a new service branch, it is defaulting to the current Air Force terminology ...
Iodine in potassium iodide added to an alcoholic solution of the base in the presence of a little hydrochloric acid gives a characteristic periodide, B 2 ·HI·I 2, crystallizing in steel-blue needles with melting point 145 °C. [7] Piperine can be hydrolyzed by an alkali into piperidine and piperic acid. [7]
Naval Support Facility Diego Garcia, abbreviated NSF Diego Garcia, [1] is a British Ministry of Defence facility leased to the United States Navy, located on the atoll Diego Garcia in the Indian Ocean, for an initial period of 99 years after the forced removal and expulsion of over 2,000 native inhabitants of the island.
The Malabar Transmitter Annex is currently used as an auxiliary communications annex in support of space activities for NASA and the U.S. Space Force. The facility is under the control of the Space Launch Delta 45 as an annex of Patrick Space Force Base. The annex was originally established as a naval airfield in 1943.
The last major U.S. commercial air crash occurred in February 2009 when a Continental Airlines flight out of Newark, New Jersey, operated by Colgan Air crashed into a house as it was approaching ...
In 1935 personnel from the United States Navy's Patrol Wing Two carried out some minor construction to develop the atoll for seaplane operations. They erected some buildings and a boat landing on Sand Island and blasted coral to clear a 3,600-foot (1,097 m) seaplane landing. [2]
