Rapid solid-phase immunoassay for 6-keto prostaglandin F1 alpha on microplates
(The American Association of Clinical Chemistry: Clinical Chemistry, 1990-03-01)We describe, for the measurement of 6-keto prostaglandin F1 alpha in biological media, a solid-phase immunoassay with immobilized antibodies that requires a total processing time of less than 2 h with hands-on time less ... -
Rapid, room temperature, high-density hydrogen adsorption on single-walled carbon nanotubes at atmospheric pressure assisted by a metal alloy
(Materials Research Society 2000 Fall Meeting: Symposium A: Nanotubes and Related Materials, 2001)Laser-generated, carbon single-walled nanotubes (SWNTs) adsorb hydrogen in a matter of minutes at room temperature and atmospheric pressure in the presence of a Ti-6Al-4V metal alloy. The unusual hydrogen adsorption ... -
Rapid, upward buoyant filtration combustion waves driven by convection
(Elsevier Science B.V., Amsterdam, 2001-01)A two-temperature model is employed to analyze upward buoyant filtration combustion (BFC) waves. We consider heterogeneous (solid/gas) combustion in a porous sample open to gas flow only at the top and the bottom. The ... -
Reaction of 2,4-dinitrobenzenesulfenyl chloride with quadricyclene
(The American Chemical Society: The Journal of Organic Chemistry, 1982-04-09)The treatment of quadricyclene with 2,4-dinitrobenzenesulfenyl chloride has been reinvestigated and chloro adducts 1-A and 2b-A as well as acetates 4a-A, 4b-A, 6, and 7 have been obtained. Establishing 2b-A with endo-chloride ... -
Reaction of atomic oxygen with hydrogen bromide
(The American Chemical Society: Journal of Physical Chemistry, 1973-04-26)The reaction of atomic oxygen with HBr was studied in a fast discharge flow system by monitoring epr spectra of O(3P2), Br(2P3/2), OH(2pi3/2), and H(2S1/2) at various reaction times. The experimental results were found to ... -
