N-Methyl-2-pyrrolidone (NMP) is an organic compound consisting of a 5-membered lactam. It is a colorless liquid, although impure samples can appear yellow. It is miscible with water and with most common organic solvents. It also belongs to the class of dipolar aprotic solvents such as dimethylformamide and dimethyl sulfoxide.
The living nature of NMP is due to the persistent radical effect (PRE). [3] The PRE is a phenomenon observable in some radical systems which leads to the highly favored formation of one product to the near exclusion of other radical couplings due to one of the radical species being particularly stable, existing in greater and greater concentrations as the reaction progresses while the other ...
The Virginia class, or the SSN-774 class, is the newest class of nuclear-powered cruise missile fast attack submarines in service with the United States Navy.The class is designed for a broad spectrum of open-ocean and littoral missions, including anti-submarine warfare and intelligence gathering operations.

According to Los Alamos officials, "many of the CMR facility systems and structural components are aged, outmoded, eroding, and generally deteriorating." In 1999, the NNSA decided to plan for the "end-of-life" of the CMR building around 2010. [2] [3] Thereafter planning began for the CMRR facility which would serve as a replacement. There is ...
RCA 6DS4 "Nuvistor" triode vacuum tube, ca. 20 mm high and 11 mm in diameter Nuvistor with U.S. dime for scale. The nuvistor is a type of vacuum tube announced by RCA in 1959. . Nuvistors were made to compete with the then-new bipolar junction transistors, and were much smaller than conventional tubes of the day, almost approaching the compactness of early discrete transistor casi
